From d8ff6ba86acf57bf2855a0f87630d130f4eeefb8 Mon Sep 17 00:00:00 2001 From: morningman Date: Sun, 24 May 2026 19:55:05 -0700 Subject: [PATCH 001/128] [doc](connector) add project tracking system for catalog SPI migration This multi-month refactor needs persistent state for progress, decisions, risks, and cross-session agent handoff. Establishes a file-based tracking system including dashboard, ADR decision log, deviation log, risk register, per-stage task files, per-connector tracking, and an agent collaboration playbook covering context budget / subagent usage / handoff norms. Closes 18 design decisions (D-001..D-018) and registers 14 risks (R-001..R-014).

`${doris_home}/plugins/connectors//`，FE 启动通过 `connector_plugin_root` 加载。运行时 `fe-core` 对具体连接器名一无所知；用户安装/卸载连接器无需重启 FE（决策点 D8）。 + +### 1.2 三个不可妥协的不变量 + +1. **fe-connector → fe-core 单向依赖**：禁止任何 `import org.apache.doris.{catalog,common,datasource,qe,analysis,nereids,planner}`。允许 `org.apache.doris.thrift.*`（provided）和 `org.apache.doris.connector.*` / `org.apache.doris.extension.*` / `org.apache.doris.filesystem.*`。CI 必须有 grep 守门。 +2. **Image / 元数据持久化向后兼容**：旧 FE image 中保存的 `IcebergExternalCatalog`、`PaimonExternalDatabase` 等 GSON 类型必须能被新 FE 反序列化并平滑迁移到 `PluginDrivenExternalCatalog`。范本是 `PluginDrivenExternalCatalog.gsonPostProcess()` 中对 ES/JDBC 的处理（已有），需推广到所有类型。 +3. **用户可见行为不回归**：`SHOW CREATE CATALOG`、`SHOW TABLE STATUS`、`information_schema.tables`、`EXPLAIN` 输出、错误信息、catalog `type` 字段、`engine` 字段（`getEngine` / `getEngineTableTypeName`）需保留旧名字。已经在 `PluginDrivenExternalTable.getEngine()` 用 switch 兜底，迁移过程中维护这个 switch。 + +--- + +## 2. 现状审视：先解决的 SPI 设计缺口 + +迁移之前必须先把 SPI 补齐到能承载所有六个连接器，否则边迁边补会被反复打回。 + +### 2.1 必须新增的 SPI 能力 + +> 全部加在 `fe-connector-api` 下；保持 `default` 方法策略以让现有连接器零迁移成本。 + +| 能力 | 当前在哪 | 计划新增的 SPI | +|---|---|---| +| **DDL info** —— `CreateTableInfo`/`PartitionDesc`/`DistributionDesc` 等都是 nereids 类型，连接器看不到 | `IcebergMetadataOps.createTable(CreateTableInfo)`、`HiveMetadataOps.createTable(CreateTableInfo)` | 在 `ConnectorTableOps` 增加 `createTable(session, ConnectorCreateTableRequest)`，引入 `ConnectorCreateTableRequest`、`ConnectorPartitionSpec`、`ConnectorBucketSpec` 三个 POJO；fe-core 侧加 `CreateTableInfoToConnectorRequestConverter` | +| **Procedures / Actions** —— Iceberg 10 个 `IcebergXxxAction` 通过 `BaseIcebergAction` 调用 `IcebergMetadataOps.commit*` | `datasource/iceberg/action/*` | 新增 `ConnectorProcedureOps`（`listProcedures`、`callProcedure(name, args)`），fe-core 侧 `ExecuteActionCommand` 走通用 dispatch | +| **元数据失效事件**（HMS notification）—— 21 个 `MetastoreEvent` 类 | `datasource/hive/event/MetastoreEventsProcessor` 调用 fe-core 的 `ExternalMetaCacheMgr.invalidate*` | 选项 A：把 event 处理整体搬到 `fe-connector-hms`，通过 `ConnectorContext.getMetaInvalidator()`（新增）回调 fe-core。选项 B：只把"轮询 HMS 拿事件流"和"解析事件"放连接器，"分发失效"留 fe-core。**推荐 A**（决策点 D4） | +| **事务管理器** | `transaction/HiveTransactionManager`、`IcebergTransactionManager` | 新增 `ConnectorTransactionFactory`（已存在的 `PluginDrivenTransactionManager` 当骨架），把 `HiveTransactionMgr` 内部状态搬进连接器实现 | +| **MVCC 快照** | `IcebergMvccSnapshot`、`PaimonMvccSnapshot` | 新增 `ConnectorMvccSnapshot` 类型，`ConnectorMetadata.beginQuery(session) -> ConnectorMvccSnapshot`；fe-core 侧 `MvccSnapshot` 接口由连接器提供实现 | +| **Vended credentials** | `IcebergVendedCredentialsProvider`、`PaimonVendedCredentialsProvider` | `ConnectorCapability.SUPPORTS_VENDED_CREDENTIALS` 已存在；新增 `ConnectorCredentials getCredentialsForScan(session, ConnectorScanRange)` | +| **Sys-tables / metadata-tables** | `IcebergSysExternalTable`、`PaimonSysExternalTable` | 在 `ConnectorTableOps` 增加 `listSysTableTypes()` / `getSysTableSchema(...)` | +| **Statistics 写入**（`ANALYZE TABLE`）| `HMSExternalTable.createAnalysisTask` | 把 `ExternalAnalysisTask` 改为只调 `ConnectorStatisticsOps`；新增 `setColumnStatistics` 方法 | +| **写路径 sink 配置**（不是数据本身，BE 写）| `IcebergDeleteSink`、`IcebergMergeSink`、`IcebergTableSink` | `ConnectorWriteOps.getWriteConfig` 已存在；扩展为支持 `getDeleteConfig`、`getMergeConfig`；planner 用通用 `PhysicalConnectorTableSink` | +| **Partition 列举**（给 TVF / SHOW PARTITIONS 用）| `MaxComputeExternalCatalog`、`PaimonExternalCatalog`、`HMSExternalCatalog` 各自的 `listPartition*` | 新增 `ConnectorTableOps.listPartitions(session, handle, filter)` / `listPartitionValues(session, handle, columns)` | + +### 2.2 推荐放弃 / 推迟的 SPI 演进 + +- **不要**为 ScanRange 引入更多多态——`PluginDrivenScanNode` extends `FileQueryScanNode` 的桥接策略已经验证可行（ES/JDBC）。 +- **不要**抽象 `Resource` 兼容层——旧 resource-backed catalog 用 `gsonPostProcess` 回填 `type` 已足够。 + +### 2.3 SPI 改动的版本号管理 + +`ConnectorProvider.apiVersion()` 当前固定返回 1。每次 SPI **新增** default 方法不动版本号；每次 SPI **改签名 / 删方法**版本号 +1，`ConnectorPluginManager` 中 `CURRENT_API_VERSION` 同步 +1。本计划过程中只新增 default 方法，因此版本号保持 1。 + +--- + +## 3. 阶段划分（按风险与价值排序） + +``` +┌─────────────────────────────────────────────────────────────────────┐ +│ P0: SPI 缺口补齐（不迁连接器） ~2 周 │ +│ P1: 重复代码清理 + scan-node 收口 ~1 周 │ +│ P2: trino-connector 迁移 ~2 周 最小风险，先打通流程 │ +│ P3: hudi 迁移（含 DLA 重构） ~2 周 │ +│ P4: maxcompute 迁移 ~2 周 │ +│ P5: paimon 迁移 ~3 周 │ +│ P6:

+└─────────────────────────────────────────────────────────────────────┘ +``` + +总长度估算 **~25 周**（不含 lakesoul / RemoteDoris 等遗留类型清理）。 + +### 3.1 阶段 P0：SPI 缺口补齐 + +**目标**：让 §2.1 表里所有缺口都有对应 SPI 类型/方法在 `fe-connector-api`，且至少一个连接器的现有实现已经能在 `default` 模式下正常工作。 + +**任务**： + +1. 新增 SPI 类型：`ConnectorCreateTableRequest`、`ConnectorPartitionSpec`、`ConnectorBucketSpec`、`ConnectorProcedureOps`、`ConnectorMvccSnapshot`、`ConnectorCredentials`、`ConnectorMetaInvalidator`（在 SPI 包）。 +2. 在 `ConnectorTableOps`、`ConnectorMetadata`、`ConnectorContext` 上新增对应 default 方法。 +3. 在 `fe-core` 侧加 converter：`CreateTableInfoToConnectorRequestConverter`、`ConnectorRequestToCreateTableInfoConverter`（如果需要双向）。 +4. 给 `PluginDrivenExternalCatalog` / `PluginDrivenExternalTable` 加上分发：CREATE TABLE / EXECUTE PROCEDURE / ANALYZE / SHOW PARTITIONS 都路由到 SPI。 +5. 更新 `ConnectorPluginManager` 文档：列出"新 SPI 在 v1 中以 default 方法形式添加，连接器无需更新版本号"。 +6. CI 守门：grep 脚本 `tools/check-connector-imports.sh` 在 `fe-connector/**/*.java` 中扫描禁用 import 列表，作为 maven 的 `enforcer` 步骤。 + +**完成判据**： +- `mvn -pl fe-connector verify` 全绿。 +- JDBC、ES 仍正常（回归）。 +- 一条 fake 连接器（在测试目录下）能在不实现新 SPI 的情况下编译并工作。 + +### 3.2 阶段 P1：重复清理 + scan-node 收口 + +**目标**：在迁连接器之前先把已经造成混乱的旧代码清掉，并把 `PhysicalPlanTranslator` 的 scan-node 分支从 7 个减到 1 个。 + +**任务**： + +1. 删除 fe-core 旧的 `datasource/jdbc/client/Jdbc*Client.java` 13 个文件 + `JdbcFieldSchema.java`。删除前 grep `org.apache.doris.datasource.jdbc.client` 在 fe-core 内被谁引用——预期只有 `JdbcExternalCatalog` 等已经走 SPI 的代码会引用，需要它们也搬走或改路径。 +2. 删除 fe-core 重复的 `PaimonPredicateConverter`、`McStructureHelper`，让 fe-core 通过 SPI 桥接（如果 fe-core 真的需要这两个工具，应该挪到通用工具包；但更可能它们是 leak，可直接删）。 +3. **收口 `PhysicalPlanTranslator.visitPhysicalFileScan`**：把所有 `instanceof HMSExternalTable / IcebergExternalTable / TrinoConnectorExternalTable / MaxComputeExternalTable / LakeSoulExternalTable` 分支统一改为： + - 若 `table instanceof PluginDrivenExternalTable` → 走 `PluginDrivenScanNode.create(...)` + - 兜底（迁移期）保留老分支 + - 在每个连接器迁移完成时（P3–P7）删掉对应分支。 +4. 把 `visitPhysicalHudiScan` 改为内部委托 `PluginDrivenScanNode` 处理增量场景（这里是 `getScanNodeProperties()` 的扩展）。 +5. 把 `LogicalFileScan.computeOutput` 中的 `instanceof IcebergExternalTable` / `HMSExternalTable` 改成通过 `ConnectorMetadata.getTableSchema` 拿额外列（metadata column）。 + +**完成判据**： +- `PhysicalPlanTranslator` 不再 `import` 任何具体 `*ExternalTable` 类（除迁移期 fallback）。 +- 全量回归 P0 通过。 + +### 3.3 阶段 P2：trino-connector 迁移（先开荒） + +**为什么先做它**： + +- fe-core 侧只有 6 个文件 + `source/`，且只有 2 处反向 `instanceof` 引用。 +- fe-connector-trino 已经有 13 个文件，scan/predicate/plugin loader/services provider 都已搬好。 +- 没有 transaction、没有 event、没有 ACID。 +- 失败的爆炸半径最小，可以把整个 migration playbook 跑一遍。 + +**任务清单**（**这套清单就是后续每个连接器都要走的 playbook**）： + +1. **代码层面**： + - 把 `datasource/trinoconnector/TrinoConnectorExternalCatalog/Database/Table` 中尚未在 connector 模块中的逻辑搬过去（schema cache、plugin loader 关闭、property 校验）。 + - 在 `TrinoConnectorMetadata` 实现 `getTableSchema` / `listTableNames` / `getTableHandle` / `applyFilter` / `applyProjection`（多数已在）。 + - `TrinoScanPlanProvider` 已实现 `planScan` —— review 一遍 split 数量、Thrift desc 字段。 +2. **桥接层面**： + - `CatalogFactory.SPI_READY_TYPES` 加入 `trino-connector`。 + - `PhysicalPlanTranslator` 删除 `instanceof TrinoConnectorExternalTable` 分支。 + - `PluginDrivenExternalTable.getEngine() / getEngineTableTypeName()` 加 `trino-connector` 分支。 + - 检查 `TableIf.TableType.TRINO_CONNECTOR_EXTERNAL_TABLE` 是否仍需保留作为 GSON 兼容（**保留**，并在 `gsonPostProcess` 中迁移到 `PLUGIN_EXTERNAL_TABLE`）。 +3. **持久化兼容**： + - 在 `PluginDrivenExternalCatalog.gsonPostProcess` 中加 `trinoconnector → plugin` 的 logType 迁移（已有 ES/JDBC 范本）。 + - 在 `ExternalCatalog.registerCompatibleSubtype` 注册 `TrinoConnectorExternalCatalog` → `PluginDrivenExternalCatalog`。 +4. **测试**： + - 给 `fe-connector-trino` 加单元测试（mock Trino plugin），覆盖 schema 解析、predicate 转换、scan plan。 + - regression-test 里新增 `trino_connector_migration_compat` 测试：模拟旧 FE image 反序列化。 +5. **打包**： + - 验证 `mvn package -pl fe-connector-trino` 生成的 `plugin.zip` 内容、`lib/` 排除项是否完整。 + - 文档：在 `docs-next/` 添加 trino-connector 插件安装步骤。 +6. **删除 fe-core 旧代码**（迁移完成的最后一步）： + - `rm -rf fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/` + - `CatalogFactory.java` 移除 `case "trino-connector": ...` + - 删除 `import` 失败处全部走 SPI 改造。 + +**风险点**：Trino 插件加载（`TrinoPluginManager` 在连接器内部）要确认 classloader 隔离不会破坏 fe-core 现有 Trino 用法。如果有 BE 端共用 Trino 二进制的情况，需要复核。 + +### 3.4 阶段 P3：hudi 迁移 + +**特殊性**：hudi 没有自己的 `*ExternalCatalog`，它寄生在 HMS 上——表是 `HMSExternalTable.dlaType=HUDI`。 + +**任务**： + +1. **重构 DLA 模型**：在 SPI 层显式建模"一个 HMS 表实际是 hudi 表"。两个选项： + - **选项 A**（推荐）：在 `ConnectorTableSchema.tableFormatType` 上做约定值 `HUDI` / `ICEBERG` / `HIVE`，由 HMS 连接器探测后填充；Doris 侧 `PluginDrivenExternalTable` 根据这个值决定走 `PhysicalHudiScan` 还是 `PhysicalFileScan`。 + - **选项 B**：hudi 作为独立 catalog type，但 catalog 内部委托 HMS 连接器拿元数据。 + - 决策点 D5。 +2. **迁移代码**： + - `datasource/hudi/HudiUtils.java`、`HudiSchemaCacheKey/Value`、`HudiMvccSnapshot`、`HudiPartitionProcessor` 搬入 `fe-connector-hudi`。 + - `datasource/hudi/source/` 下的 `HudiScanNode` 删除，改为 `PluginDrivenScanNode` + `HudiScanPlanProvider`（已存在）补全 incremental relation 逻辑。 + - 4 个 `HoodieIncremental*Relation` 类是和 hudi-spark 库交互，必须在连接器模块里（已在 lib），review classpath。 +3. **桥接**：`SPI_READY_TYPES` 加 hudi。但因为 hudi 不能独立 CREATE CATALOG（它依附 HMS），CatalogFactory 路由可能要特别处理：用户写 `type=hms`，由 HMS 连接器自行判断 dlaType 后用 hudi-specific 行为。 +4. **测试**：用 hudi 测试集群跑读时序，确保 incremental query 不回归。 + +### 3.5 阶段 P4：maxcompute 迁移 + +**任务**： + +1. 搬 `MCTransaction`、`MaxComputeExternalMetaCache`、`MaxComputeSchemaCacheValue` 到 `fe-connector-maxcompute`。 +2. 删 fe-core 重复的 `McStructureHelper`（P1 已删，确认）。 +3. `MaxComputeMetadataOps` 现有 fe-core 实现搬到连接器（连接器内已有 `MaxComputeConnectorMetadata` 骨架）。 +4. 收口 `PhysicalPlanTranslator`、`ShowPartitionsCommand`、`PartitionsTableValuedFunction` 中对 `MaxComputeExternalCatalog/Table` 的 12 处 instanceof。 +5. `SPI_READY_TYPES` 加 `max_compute`。 +6. 删 `datasource/maxcompute/`。 + +### 3.6 阶段 P5：paimon 迁移 + +**复杂度跃升原因**： + +- 6 个 catalog flavor（HMS/DLF/REST/File/Base/Factory）—— 在连接器内用工厂模式重组：`PaimonConnectorProvider.create()` 根据 properties 实例化 `Catalog`。 +- `PaimonMvccSnapshot` —— 用 P0 新增的 `ConnectorMvccSnapshot` 类型承接。 +- `PaimonVendedCredentialsProvider` —— 用 P0 新增的 vended credentials SPI 承接。 +- `PaimonSysExternalTable` —— 用 P0 新增的 sys table SPI 承接。 +- BE 通过 JNI 调用 paimon-reader，序列化 Paimon Table 通过 `ConnectorScanPlanProvider.getSerializedTable` 已有支持。 + +**任务**： + +1. 完整 port `PaimonMetadataOps` → `PaimonConnectorMetadata`（注意 partitionStatistics、bucketing）。 +2.

+ +--- + +## 一、为什么需要规范 + +LLM agent 协作的三大失效模式： + +1. **Context 中毒**：单 session 累积太多无关信息，模型注意力分散、决策质量下降、出现幻觉。 +2. **认知断层**：换 session 后失去前情，重复探索 / 推翻已有决策 / 重新发明轮子。 +3. **维护脱节**：代码改了文档不改，下次进 session 时基于过时文档做错误判断。 + +本规范用三类工具应对： +- **Context 预算与监控**（§2）—— 防失效模式 1 +- **Subagent 与 Handoff**（§3、§4）—— 防失效模式 1、2 +- **强制纪律**（§5）—— 防失效模式 3 + +--- + +## 二、Context 预算 + +### 2.1 单 session 预算 + +| Context 使用率 | 状态 | 推荐行为 | +|---|---|---| +| **0–40%** | 🟢 健康 | 正常工作，可以做任何任务 | +| **40–60%** | 🟢 健康偏高 | 开始倾向于把"独立的探索 / 大文件读"转给 subagent | +| **60–75%** | 🟡 警觉 | **不再读 ≥500 行的整文件**；只做精确 grep / offset+limit read；准备 handoff 草稿 | +| **75–85%** | 🟠 高危 | **停止接新任务**；完成手头 1 个原子工作；写 HANDOFF.md；通知用户切 session | +| **>85%** | 🔴 危险 | **只做记录性工作**（更新 PROGRESS / HANDOFF）；不再做任何决策 / 代码生成 | + +> Claude Code 中可通过 `/context` 查看当前用量；如不可见，按"已发起的工具调用数 + 已读文件总行数"粗略估算。 + +### 2.2 用户对 session 的隐式预期 + +如果用户在一次 session 中要求"重构 X 模块 + 写文档 + 提交 PR"，agent 应： + +- 评估 context 占用：单凭 RFC + 现有代码探索就可能吃掉 30-40% +- **主动报告**：在开始执行前告知 "此任务预计占用约 40% context，是否需要先写 handoff 占位以便分两个 session 完成？" + +### 2.3 节省 context 的硬性技巧 + +1. **永远不要 `Read` 整个 >1000 行的文件** —— 用 `grep` 定位行号，再用 `offset + limit` 精读。 +2. **永远不要重复 grep 同一个 pattern** —— 在 session 心智里记住结果。 +3. **避免 `cat` / `find -type f -name '*.java'` 全量列举** —— 用更精准的 grep / find 加过滤。 +4. **避免 `git log -p`** —— 用 `git log --oneline -20`，需要 diff 再单独 `git show `。 +5. **大文件总结优先用 subagent**（见 §3）：让 subagent 读 5000 行返回 200 字总结。 + +--- + +## 三、Subagent 使用规范 + +### 3.1 何时**必须**用 subagent + +- **跨 5+ 文件的代码搜索 / 调研**（如"找出 fe-core 中所有 instanceof HMSExternalCatalog 的地方"） +- **读取 >1000 行的单文件后只取关键信息**（如 IcebergMetadataOps.java 1247 行，只需了解 createTable 路径） +- **独立的、不影响主线决策的小重构**（如"批量改 import 路径"，给 subagent prompt + 文件列表，背景执行） +- **独立的代码评审**（如"review 这次 PR 的安全性"，需要重读大量上下文） + +### 3.2 何时**不要**用 subagent + +- 主线决策环节 —— subagent 给的建议你最终还是要消化，不如自己做 +- 1-2 次 grep / read 就能解决的简单查找 —— 启动 subagent 的固定开销不值得 +- 需要持续交互的探索（边读边问"那 X 呢"）—— subagent 一次性输出，互动不便 +- 涉及"修改后立即验证"的小改动 —— 主 session 闭环更快 + +### 3.3 写 subagent prompt 的硬性规则 + +``` +1. 自包含：不能假设 subagent 知道主线对话内容。明确说"working directory: /...", + "background: 这是 XX 项目的 YY 阶段，目标是 ZZ"。 +2. 输出格式约束：明确"返回 markdown 表格 / 总字数 ≤ 500 / 只列文件路径不带代码"。 +3. 范围约束：明确"只看 fe-core 目录"、"忽略 test 目录"、"不读 README"。 +4. 决策权约束：明确"只调研，不做任何修改"或"可以修改 X 但不能动 Y"。 +5. 一次性：避免让 subagent 内部继续延伸调研——主 session 来决定下一步。 +``` + +### 3.4 Subagent 类型选择（Claude Code 内） + +| 任务类型 | 推荐 subagent | 备注 | +|---|---|---| +| 大范围代码搜索 | `Explore` | 只读、快、context 隔离 | +| 多步独立工作 | `general-purpose` | 可以执行 grep / read / edit | +| 实现计划设计 | `Plan` | 只产出方案不写代码 | +| 都不适合 | `claude`（默认）| 兜底 | + +### 3.5 Background 模式 + +长耗时任务（如 `mvn test`、跨模块 build）使用 `run_in_background: true`，主 session 不被阻塞。完成时会自动通知，**不要 sleep 轮询**。 + +--- + +## 四、Handoff（跨 session 接管） + +### 4.1 何时**必须**写 handoff + +- Context 使用率 ≥ 70%（§2.1） +- 当前 P 阶段结束（如 P0 → P1 切换） +- 工作天然分段（如"下周再继续"） +- 出现长时间阻塞，等其他人 review / 等 CI 跑（≥4 小时） +- 用户主动说"今天到此为止" + +### 4.2 何时**不需要**写 handoff + +- 同一 session 内自然继续 +- Context < 50% 且任务还很短 + +### 4.3 Handoff 文档结构 + +见 [`HANDOFF.md`](./HANDOFF.md) 模板。核心字段： + +1. **本 session 完成了什么**（具体到 task ID、PR、commit） +2. **当前正在做的事是否完整**（如果中途停的，写明卡在哪个文件、哪一行） +3. **关键认知 / 临时发现**（如"刚发现 X 类的 Y 方法有意外副作用"——这种东西不写下来下次会重复踩坑） +4. **下一个 session 第一件事做什么**（精确到 task ID + 第一行代码 / 命令） +5. **当前 session 没解决但需要标记的问题**（不是 TODO 而是"开放问题"） + +### 4.4 Handoff 文件存放 + +- 单个滚动文件 `plan-doc/HANDOFF.md` +- 每次 session 结束时**覆盖式更新** +- 历史 handoff 通过 `git log plan-doc/HANDOFF.md` 查看 +- **不要**建 `handoffs/2026-05-24.md` 这种归档目录 —— git history 已经胜任 + +### 4.5 接管新 session 的开场流程 + +新 session 开始第一件事（**所有 agent 必须遵守**）： + +``` +1. Read plan-doc/PROGRESS.md ← 全局状态 +2. Read plan-doc/HANDOFF.md ← 上次留言 +3. 如果 HANDOFF 标记当前 task： + Read plan-doc/tasks/Pn-*.md 中对应 task 块 +4. 用一句话向用户复述："上次 session 做完了 X，下一步是 Y，对吗？" +5. 等用户确认后开始 +``` + +**不要**在没读 HANDOFF 的情况下问"我们上次做到哪了" —— 这是失败模式。 + +--- + +## 五、强制纪律 + +### 5.1 文档同步纪律 + +每次完成 task： +1. 更新 `tasks/Pn-*.md` 对应 task 状态 +2. 更新 `PROGRESS.md` §三和§四 +3. 更新 `connectors/.md`（如果该 task 属于某个连接器） +4. 如果产生新决策 → `decisions-log.md` 新增 D-NNN +5. 如果发现偏差 → `deviations-log.md` 新增 DV-NNN + +**5 步缺一不可**。否则下次 session 看到的状态就是错的。 + +### 5.2 RFC 修改纪律 + +任何修改 `01-spi-extensions-rfc.md` 的行为： +1. 先在 `deviations-log.md` 或 `decisions-log.md` 留痕（区别见 [README §3.1](./README.md)） +2. 在 RFC 该节加 `（D-NNN / DV-NNN 修订 YYYY-MM-DD）`脚注 +3. 不要 silent edit + +### 5.3 Task ID 纪律 + +- Task ID 一旦分配**永不复用** +- 删除的 task 标 `[deleted YYYY-MM-DD]` 保留占位行 +- 重命名 task 不改 ID + +### 5.4 提交信息纪律 + +PR title 第一行必须 `[Pn-Tnn] `，例如： +``` +[P0-T03] Implement ConnectorMetaInvalidator interface +``` + +--- + +## 六、Anti-Patterns（绝对禁止） + +| 反模式 | 为什么禁止 | 正确做法 | +|---|---|---| +| 一个 session 又读 RFC、又改 SPI、又写实现、又跑测试 | Context 爆炸；决策质量下降 | 拆 session：阅读/设计 → handoff → 实现 → handoff → 验证 | +| 跨 session 凭记忆继续工作 | 模型完全没记忆，认知断层 | 强制读 HANDOFF | +| Subagent 也用来做"小事" | 启动开销大于收益 | <2 次 grep 直接主线做 | +| 把 RFC 当 PROGRESS 用 | RFC 是设计稳定文档，频繁更新会污染 git history | PROGRESS / tasks / handoff 才是状态文件 | +| Handoff 写得像周报 | 周报对用户有用，对下一个 agent 无用 | 写"下一步第一行命令是什么"才有用 | +| 多个 session 并发改同一 task | 重复劳动 / 文档冲突 | 同一时刻一个 task 只一个 owner | +| Decision / Deviation 直接写到 RFC 里不进 log | 失去追溯性 | 先 log 再改 RFC | + +--- + +## 七、各类 session 的典型节奏（参考） + +### 7.1 "设计 + 评审" session（高密度阅读） + +```

+--- + +## 八、Context "重启"策略 + +如果 context 已经超 75% 但任务还没做完： + +1. **优先保存状态**：立即写 HANDOFF.md，详细到下一行代码该写什么 +2. **完成原子收尾**：当前正在 Edit 的文件**改完 + 保存**，不要留半截 +3. **更新 PROGRESS**：把已完成的 task 标 ✅ +4. **提醒用户切 session**："Context 已 ~78%，建议开新 session 继续。HANDOFF 已写好，新 session 第一句话发 'continue from handoff' 即可。" +5. **不要硬撑**：每多用 1% context 都在降低质量 + +--- + +## 九、Multi-agent 协作的边界 + +本项目原则上一个 task 由一个 agent 推进，但允许： + +- **并行 subagent**：调研 / 测试 / build 等独立任务并行 +- **审计 subagent**：让一个 subagent 审核主线工作（如"以挑刺 reviewer 视角看这次改动"） +- **接力**：handoff 后由完全不同的 agent / 人接手 + +**不允许**： +- 同时两个 agent 改同一 task +- Subagent 跨阶段（subagent 只做本 session 的工作，不要让 subagent 自己写 HANDOFF） + +--- + +## 十、面向"未来 agent"的元规则 + +如果你（未来 agent）发现本规范本身需要修改： + +1. 不要直接改本文件 —— 先在 `deviations-log.md` 写 `DV-NNN: AGENT-PLAYBOOK 规则 X 在场景 Y 不适用` +2. 与用户讨论后再修改本文件 +3. 修改时在文末 §十一 加版本号 + 变更说明 + +--- + +## 十一、版本 + +| 版本 | 日期 | 变更 | +|---|---|---| +| v1 | 2026-05-24 | 初版（与 README、PROGRESS、HANDOFF 同时建立） | diff --git a/plan-doc/HANDOFF.md

**`PhysicalPlanTranslator.visitPhysicalFileScan` line 734-790 是 7-way switch 的单点收口** —— P1 首要清理目标。 +4. **`ConnectorTransactionHandle` 是 24 行空 marker 接口** —— `ConnectorTransaction` 计划继承它，不破坏现有引用。 +5. **`ConnectorPartitionInfo` 已存在** —— RFC E10 复用并扩展 3 个 long 字段（向后兼容构造器）。 +6. **`SPI_READY_TYPES` 白名单当前只含 `jdbc`, `es`** —— 后续连接器加入这个 ImmutableSet 即可生效。 +7. **`fe-connector-hms` 是共享库不是插件** —— 无

**关联**：[01-spi-extensions-rfc.md §11.2](./01-spi-extensions-rfc.md) +- **背景**：`ConnectorColumnStatistics.minValue / maxValue` 用 `Object` 装载，缺少静态类型检查可能导致 connector 间不一致。 +- **决策**：在 `ConnectorColumnStatistics` javadoc 中列出 `ConnectorType` ↔ Java 装箱类型完整映射表（如 INT→Integer、TIMESTAMP→Instant、BINARY→byte[]）；连接器读取不匹配类型时**抛 `IllegalArgumentException`**，由 fe-core 转成 `UserException`。 +- **替代方案**：（a）引入泛型 `ConnectorColumnStatistics`——过于复杂、跨方法签名传染；（b）引入 union 类型——Java 不原生支持。 +- **影响**：仅 javadoc 与运行时检查，无签名变化。 + +--- + +### D-017 — sys-table 命名统一 `$suffix`（原 U5） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[01-spi-extensions-rfc.md §10](./01-spi-extensions-rfc.md) +- **背景**：Iceberg / Paimon 各自有 sys-table（`tbl$snapshots`、`tbl$history` 等）。命名风格 `$xxx` vs `xxx@` vs `[xxx]` 跨方言不一致。 +- **决策**：SPI 层固定 `$suffix` 约定。如未来出现冲突（如某 SQL dialect 把 `$` 视为变量前缀），通过 catalog property `sys_table_separator` 提供别名机制，但**不在本计划范围**。 +- **影响**：所有 sys-table 实现统一遵循。 + +--- + +### D-016 — `getCredentialsForScans` 批量化（原 U4） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[01-spi-extensions-rfc.md §9](./01-spi-extensions-rfc.md) +- **背景**：原设计单 range 调一次 `getCredentialsForScan`，N 个 range 触发 N 次 STS 调用，可能撞限流。 +- **决策**：签名定为 `Map getCredentialsForScans(session, handle, List)`。连接器自由决定 STS 调用粒度（1 次共享 / 按 prefix 分组 / 1:1）。fe-core 一个 scan node 一次调用。 +- **替代方案**：保持单个 + 加内部缓存——把缓存策略推给每个 connector，不一致风险更高。 +- **影响**：替换原 `getCredentialsForScan` 单个签名。调用位置从 `setScanParams` 移到 `createScanRangeLocations`。 + +--- + +### D-015 — `ConnectorTransaction.getTransactionId` 由连接器分配（原 U3） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[01-spi-extensions-rfc.md §7.2](./01-spi-extensions-rfc.md) +- **背景**：transaction ID 是连接器自己分配还是 fe-core 统一分配？ +- **决策**：连接器分配。连接器最清楚事务 ID 与外部系统（如 HMS transaction id、Iceberg snapshot id）的对应关系。fe-core 在 `PluginDrivenTransactionManager` 用 `Map` 索引即可。 +- **影响**：`ConnectorTransaction.getTransactionId()` 是 connector-side 字段。 + +--- + +### D-014 — 不新增 `invalidateColumnStatistics`（原 U2） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[01-spi-extensions-rfc.md §6](./01-spi-extensions-rfc.md) +- **背景**：是否给 `ConnectorMetaInvalidator` 加 `invalidateColumnStatistics(...)`？ +- **决策**：暂不加。column stats 失效一并挂在 `invalidateTable` 上，避免接口表面膨胀。如后续发现频繁需要单独失效列统计，再加方法（向后兼容 default 即可）。 +- **影响**：`ConnectorMetaInvalidator` 接口保持 5 个方法（catalog / database / table / partition / statistics 整张表）。 + +--- + +### D-013 — `ConnectorProcedureOps.listProcedures` 一次性返回（原 U1） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[01-spi-extensions-rfc.md §5.2](./01-spi-extensions-rfc.md) +- **背景**：connector 暴露的 procedure 列表是初始化时固定还是允许运行时变化？ +- **决策**：一次性。Connector 生命周期内稳定；如外部系统的可用 procedure 集合变化，必须重新创建 catalog。 +- **理由**：fe-core 可缓存该列表用于 `SHOW PROCEDURES`、autocompletion；动态变化模型复杂度不值得。 +- **影响**：在 `listProcedures()` 的 javadoc 中明确写出"Lifecycle contract"。 + +--- + +### D-012 — Connector 安装初版强制重启 FE（原 D12） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：装新 connector 后是否要求重启 FE？ +- **决策**：初版强制重启。原因：跨连接器共享类型可能有 classloader 缓存问题，强制重启避免难复现的 corner case。后续版本可考虑热加载。 +- **影响**：文档明确 + 装包流程明确。 + +--- + +### D-011 — `RemoteDorisExternalCatalog` 不在本计划主线（原 D11） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：Doris-to-Doris federation 是否做成 connector？ +- **决策**：长期目标做 connector，但**单独立项**，不在本计划主线（25 周计划中）。 +- **影响**：`RemoteDorisExternalCatalog` 在 P8 不删除；保留独立路径。 + +--- + +### D-010 — `LakeSoulExternalCatalog` 在 P8 删除（原 D10） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：`CatalogFactory` 已抛 "Lakesoul catalog is no longer supported"，但类文件仍在。 +- **决策**：在 P8 收尾时删除剩余 `datasource/lakesoul/` 全部类。 +- **影响**：P8 task 增加 lakesoul 清理项。 + +--- + +### D-009 — API 版本号本计划永不 +1（原 D9） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md)、[01-spi-extensions-rfc.md §2.1](./01-spi-extensions-rfc.md) +- **背景**：`ConnectorProvider.apiVersion()` 何时 +1？ +- **决策**：本计划范围内（25 周）保持 `apiVersion=1`，只新增 default 方法，不破坏现有签名。 +- **影响**：所有 SPI 扩展必须用 default 方法。如真有不可避免的 breaking change，需走 deviation 流程并升级到 v2。 + +--- + +### D-008 — 生产强制目录式插件（原 D8） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：是否允许 built-in connector（classpath 中直接打进 FE jar）？ +- **决策**：否。built-in 模式只用于测试（ServiceLoader 扫 classpath）；生产部署必须从 `connector_plugin_root` 目录加载 plugin zip。 +- **影响**：FE 发行包不含 connector jar；运维流程文档要明确插件部署步骤。 + +--- + +### D-007 — kafka/kinesis/odbc/doris 不在本计划范围（原 D7） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：`datasource/` 下还有 kafka / kinesis / odbc / doris 子目录，是否一并迁移？ +- **决策**：否。流式数据源（kafka/kinesis）与外部 catalog 模型不同；odbc 是 BE-driven；doris 是内部联邦。单独立项。 +- **影响**：P8 不删除这 4 个子目录。 + +--- + +### D-006 — Iceberg snapshot/manifest cache 放连接器内（原 D6） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md)、[01-spi-extensions-rfc.md §8](./01-spi-extensions-rfc.md) +- **背景**：Iceberg 的 snapshot cache 和 manifest cache 是 fe-core 通用基础设施还是连接器内部细节？ +- **决策**：连接器内部细节。fe-core 不感知。连接器自己管理生命周期、淘汰策略。 +- **替代方案**：放 `fe-core/datasource/metacache/` 通用框架——会增加 fe-core 对 Iceberg 概念的耦合。 +- **影响**：P6 迁移时把 `cache/IcebergManifestCacheLoader` 等整体搬到 `fe-connector-iceberg`。 + +--- + +### D-005 — Hudi / Iceberg-on-HMS DLA 模型方案 A（原 D5） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §3.4](./00-master-plan.md) +- **背景**：HMS 表可能"实际是" Hudi 或 Iceberg。如何在 SPI 层建模？ +- **决策**：方案 A — 用 `ConnectorTableSchema.tableFormatType` 字段（值如 `"HIVE"` / `"HUDI"` / `"ICEBERG"`），由 HMS connector 探测后填充；fe-core 据此 dispatch 到对应 `PhysicalXxxScan`。 +- **替代方案**：方案 B — Hudi 作为独立 catalog type，内部委托 HMS——增加 catalog 实例数，用户混淆度高。 +- **影响**：P3 hudi 和 P7 hive 迁移都依赖此模型。 + +--- + +### D-004 — HMS event pipeline 放 fe-connector-hms（原 D4） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §3.8](./00-master-plan.md)、[01-spi-extensions-rfc.md §6](./01-spi-extensions-rfc.md) +- **背景**：21 个 HMS event 类放 fe-core 还是 fe-connector-hms？ +- **决策**：fe-connector-hms。通过新 SPI 接口 `ConnectorMetaInvalidator`（在 `ConnectorContext` 暴露）回调 fe-core 的 `ExternalMetaCacheMgr`。 +- **替代方案**：只把"轮询 HMS 拿事件流"放 connector，"解析事件 + 分发失效"留 fe-core——分散，不利于演化。 +- **影响**：P7.2 完整迁移 21 个类 + `MetastoreEventsProcessor`。`HiveConnector.create(...)` 启动 listener 线程；`close()` 停止。 + +--- + +### D-003 — 旧 `*ExternalCatalog` 子类全部删除（原 D3） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：迁移过程中是保留旧 `IcebergExternalCatalog` 等类作为"中间形态"还是彻底删除？ +- **决策**：全部删除。中间形态会让代码长期处于"两套并存"状态，维护负担、bug 风险都更大。 +- **替代方案**：保留一段"deprecated 但可用"期——拒绝，因为旧实现实质上不会被维护。 +- **影响**：P8 强制删除所有 `*ExternalCatalog` / `*ExternalDatabase` / `*ExternalTable` 类；前置工作是 P2-P7 把所有反向 `instanceof` 改为通用接口调用。 + +--- + +### D-002 — `PluginDrivenScanNode` 长期保持 extends `FileQueryScanNode`（原 D2） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：`PluginDrivenScanNode` 当前继承 `FileQueryScanNode`，但 JDBC / ES 本质不是文件扫描，用 `FORMAT_JNI` 兜底。是否要重构为更彻底的多态？ +- **决策**：长期保持当前继承结构。JDBC / ES 的 `FORMAT_JNI` 兜底已被 ES/JDBC 验证可行。重构成本高、收益不明确。 +- **影响**：所有 plugin-driven connector 走同一 scan-node 子类，简化 dispatch 逻辑。 + +--- + +### D-001 — 沿用 `SUPPORTS_PASSTHROUGH_QUERY`（原 D1） + +- **日期**：2026-05-24 +- **状态**：✅ 生效 +- **关联**：[00-master-plan.md §5](./00-master-plan.md) +- **背景**：是否要为 SQL 透传以外的远程 query 类型（如 `query()` TVF）新增 SPI？ +- **决策**：不新增。已有 `ConnectorCapability.SUPPORTS_PASSTHROUGH_QUERY` + `ConnectorTableOps.getColumnsFromQuery` 覆盖了主要场景，沿用。 +- **影响**：无新增 API。 + +--- + +## 附录：决策模板 + +新增决策时复制以下模板到顶部（在 §详细记录 下方），并更新 §📋 索引表。 + +```markdown +### D-NNN — <一句话主题> + +- **日期**：YYYY-MM-DD +-

aa2c2871967668b8bc917f596fe33783e45febed Mon Sep 17 00:00:00 2001 From: "Mingyu Chen (Rayner)" Date: Mon, 25 May 2026 08:02:10 -0700 Subject: [PATCH 002/128] [feat](connector) P0 SPI baseline + DDL/Partition + import gate (T03-T27) (#63582) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Lands the P0 SPI baseline for the catalog-SPI migration (master plan §3.1 / RFC §2.1), with zero impact on the already-migrated JDBC + ES connectors. - **Batch 0** (commits 1-2): SPI types + fe-core bridges — `ConnectorMetaInvalidator`, `ConnectorTransaction`, `ConnectorMvccSnapshot`, `ExternalMetaCacheInvalidator`, `ConnectorMvccSnapshotAdapter`, `PluginDrivenTransactionManager` generalization. - **Batch 1** (commit 3): DDL + Partition SPI — `ConnectorCreateTableRequest` + 4 spec POJOs, 4 new defaults on `ConnectorTableOps`, 3 new fields on `ConnectorPartitionInfo`, fe-core converter, `PluginDrivenExternalCatalog.createTable` routing. - **Batch 2** (commit 4): Import-gate + unit tests — `tools/check-connector-imports.sh` wired through exec-maven-plugin; `FakeConnectorPlugin` covering every default fall-through; routing tests for the invalidator; converter tests for all 4 partition styles + 2 bucket flavors. ## Commits - `[feat](connector) add P0 batch 0 SPI baseline: MetaInvalidator / Transaction / MvccSnapshot` (T03-T08) - `[feat](connector) wire P0 batch 0 SPI into fe-core` (T09-T12) - `[feat](connector) add P0 batch 1 SPI: CreateTableRequest + listPartitions` (T13-T20) - `[feat](connector) add P0 batch 2 gate + unit tests` (T21-T23, T26-T27) ## Test plan - [x] `mvn -pl fe-connector/fe-connector-api,fe-connector/fe-connector-spi -am compile` — SPI modules compile - [x] `mvn -pl fe-core -am compile -Dmaven.build.cache.enabled=false` — fe-core compile - [x] `mvn -pl fe-core checkstyle:check` — 0 violations - [x] `mvn -pl fe-connector validate` — import gate runs and passes (baseline clean) - [x] `mvn -pl fe-core -am test -Dtest='FakeConnectorPluginTest,ExternalMetaCacheInvalidatorTest,CreateTableInfoToConnectorRequestConverterTest,ConnectorPluginManagerTest,ConnectorSessionImplTest'` — 39/39 green - [x] `mvn -pl fe-connector/fe-connector-jdbc,fe-connector/fe-connector-es -am compile` — downstream connectors compile unchanged - [ ] JDBC regression-test suite (T24) — to be exercised by this PR's CI pipeline - [ ] ES regression-test suite (T25) — to be exercised by this PR's CI pipeline ## Tracking Full plan, decisions, and risk log live under `plan-doc/` in the repo (introduced by 63159837043, already on the

+- **选项 B1**：P0-T28 benchmark（R-006 缓解，1k catalog × `listTableNames` 性能基线）。原列入 P1，可前置到 P0 末加，让 P0 出阶段干净 +- **选项 B2**：直接进 P1（scan-node 收口 + 重复清理）。P0 既然 93% 接近收尾，T24/T25 跑完即关阶段 +- 推荐 B2（B1 在 P1 阶段开题更自然，benchmark 跟 scan-node 工作正好同期） -**强烈推荐 Track B → Track A**：本次 session 创建了 17 个文档但都没提交；先 commit 沉淀，否则一旦本地文件意外丢失，所有跟踪机制要重做。 +### ~~Track C：commit 批 2~~（已收尾） + +批 2 已合入 `catalog-spi-00`；无需再开 Track C。 --- ## ⚠️ 开放问题 / 风险提示 -1. **跟踪机制本身从未被实际"使用"过**——所有文件都是预期模板，实际产生 deviation / 周维护时是否好用还要看。后续 session 第一次 append decision-log 或 deviation-log 时如果发现模板缺字段，按 DV 流程改 README §3。 -2. **`tools/check-connector-imports.sh` 守门脚本仍未实现**（RFC §15.4 + tasks/P0 P0-T21）—— P0 末必须完成。 -3. **`maven enforcer` 接入方式未敲定**——技术决策，留 P0 实施时定。 -4. **本 session 大量决策（D-001..D-018）尚未进入 git history** —— 见 Track B 推荐。 -5. **本跟踪机制没有 PMC review**——单人推进风险。建议在开 P0 编码前至少让一位 reviewer 看一遍 README + AGENT-PLAYBOOK。 +继承上版 7 项不变（删了"未 commit batch 1"项；增加本场 trade-off）： + +1. **守门挂 `exec-maven-plugin` 而非 `maven-enforcer-plugin`**：RFC §15.4 原文写后者。本场用前者（等价实现，0 新依赖）。是否在 RFC §15.4 加脚注说明这个偏差？**判断**：trade-off 在 RFC 范围内，不升 DV；若有 reviewer 强烈要求 enforcer 写 Java Rule 类再重做 +2. **守门 `inherited=false`**：dev 跑单连接器 `mvn -pl fe-connector/fe-connector-iceberg compile` 时不会触发。是否要改 `inherited=true`？**判断**：现状没人手动跑这条命令日常迭代，重复扫的成本（11 × ~50ms）也不大；如未来某个连接器开发体感差再改 +3. **`invalidatePartition` 测试 pin 当前 fallback**：一旦 SPI 在该方法签名上加 column 名携带能力，bridge 和测试必须同步更新。测试已留 inline comment 描述意图 +4. **`CreateTableInfo` 用 mock**：converter 改用 mock 之外的 getter 时，需在 `stubInfo` helper 加新 stub。Trade-off：测试更聚焦但代价是输入对象不"真实" +5. **partition 风格的 IDENTITY vs TRANSFORM 判别**：测试覆盖了"全 UnboundSlot → IDENTITY"和"含 UnboundFunction → TRANSFORM"两路径，但没覆盖"UnboundSlot + UnboundFunction 混合"——按 converter 当前实现，只要有任意一个 UnboundFunction 就走 TRANSFORM 路径，UnboundSlot 在 `convertFields()` 里也会被识别为 `identity` transform。这个混合场景的语义是否符合预期？**判断**：RFC §4.2 未明确混合用法，留待 P5/P6 Iceberg 真正用到时评估 +6. （沿用）`ColumnDefinition.defaultValue` SPI 缺位 +7.

Three surgical changes route `PluginDrivenExternalTable` first in the nereids translator hot paths so already-migrated SPI connectors (JDBC, ES) take the SPI route, while the existing `instanceof XExternalTable` chains remain as fallbacks for connectors still pending migration (P3–P7). - **T3** — `PhysicalPlanTranslator.visitPhysicalFileScan`: move the existing `PluginDrivenExternalTable` branch from position 8 to position 1; the 7 connector-specific branches (HMS / Iceberg / Paimon / Trino / MaxCompute / LakeSoul / RemoteDoris) stay in place as migration-period fallbacks - **T4** — `PhysicalPlanTranslator.visitPhysicalHudiScan`: add a `PluginDrivenExternalTable` branch routed to `PluginDrivenScanNode.create(...)`, threading `tableSnapshot` + `scanParams` through `FileQueryScanNode` setters; `incrementalRelation` flagged as a P3 Hudi SPI extension TODO. The new branch is unreachable today (`PhysicalHudiScan` is only built for `HMSExternalTable + DLAType.HUDI`), so this is groundwork for P3 with zero current-day runtime impact - **T5** — `LogicalFileScan`: in `computeOutput()`, add a `PluginDrivenExternalTable` branch calling new helper `computePluginDrivenOutput()` — same shape as `computeIcebergOutput`, using `getFullSchema()` + virtualColumns; in `supportPruneNestedColumn()`, add an explicit `PluginDrivenExternalTable → false` branch. Both behaviorally equivalent for JDBC/ES today since they have no hidden cols and no virtualColumns P1 batch B (T1 — delete 13 legacy `Jdbc*Client` + `JdbcFieldSchema`) is deferred to P8 because the 3 fe-core callers — `PostgresResourceValidator`, `StreamingJobUtils`, `CdcStreamTableValuedFunction` — are live CDC streaming code that requires SPI extension for `getPrimaryKeys` / `getColumnsFromJdbc` / `listTables`, which is out of P1 surgical scope.

trino-connector to catalog SPI (T01-T13) (#64096) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### What problem does this PR solve? Related PR: #63582 (P0 — SPI baseline), #63641 (P1 — nereids plugin-driven routing) Problem Summary: This is **P2** of the catalog SPI migration and targets the `branch-catalog-spi` feature branch (continuing P0 #63582 and P1 #63641). It fully migrates `trino-connector` off the legacy in-tree `fe-core/datasource/trinoconnector/` implementation and onto the connector SPI module `fe-connector-trino`, making `trino-connector` the first connector to complete the SPI consumption playbook that later connectors will reuse as a template. All five batches land together so there is no intermediate state where a newly-created trino catalog cannot be serialized. **Batch A — complete the SPI surface (`fe-connector-trino` only, no fe-core changes)** - `TrinoConnectorProvider.validateProperties`: enforce the required `trino.connector.name` property at `CREATE CATALOG` time (ported from the legacy `checkProperties`). - `TrinoDorisConnector.preCreateValidation`: call `ensureInitialized()` so plugin loading + connector-factory resolution happen at catalog creation instead of being deferred to the first `SELECT`. - `TrinoConnectorDorisMetadata.applyFilter` / `applyProjection`: bridge Trino native filter/projection pushdown, reusing `TrinoPredicateConverter` to translate a Doris `ConnectorExpression` into a Trino `TupleDomain`. `remainingFilter` is conservatively returned as the original expression to match legacy behavior (conjuncts are not stripped; BE re-evaluates them). **Batch B — fe-core bridge for image compatibility** - `GsonUtils`: atomically replace the three legacy `registerSubtype` entries (`TrinoConnectorExternalCatalog` / `Database` / `Table`) with `registerCompatibleSubtype` redirects onto the `PluginDrivenExternal*` hierarchy. This must be atomic — `RuntimeTypeAdapterFactory` rejects duplicate labels, so keeping both bindings would throw at static init. Mirrors what ES/JDBC already did. - `PluginDrivenExternalCatalog.gsonPostProcess`: extract a `legacyLogTypeToCatalogType()` helper that maps `Type.TRINO_CONNECTOR` → `"trino-connector"`; the generic `name().toLowerCase()` would otherwise produce the wrong `"trino_connector"` (underscore) that `CatalogFactory` does not recognize. - `PluginDrivenExternalTable.getEngine()` / `getEngineTableTypeName()`: add `trino-connector` branches that preserve the legacy engine-name / table-type display across `SHOW TABLE STATUS` and `information_schema`. **Batch C — flip the switch** - Add `"trino-connector"` to `CatalogFactory.SPI_READY_TYPES` so catalog creation routes through the SPI path. **Batch D — remove legacy code** - Drop the `instanceof TrinoConnectorExternalTable` scan branch in `PhysicalPlanTranslator` (the `PluginDrivenExternalTable` SPI branch already handles it). - Drop `case "trino-connector"` in `CatalogFactory`. - Delete `fe-core/datasource/trinoconnector/` (10 files) and the now-dead legacy `TrinoConnectorPredicateTest`. - Route the `TRINO_CONNECTOR` db-build case in `ExternalCatalog` to `PluginDrivenExternalDatabase` (mirrors the migrated JDBC case). - **Retained for image compatibility**: the `InitCatalogLog.Type.TRINO_CONNECTOR` and `TableType.TRINO_CONNECTOR_EXTERNAL_TABLE` enums, the GsonUtils redirects, and the `MetastoreProperties` trino-connector entry. **Batch E — tests + tracking docs** - 29 JUnit 5 unit tests over the plugin-free converters: - `TrinoPredicateConverterTest` — `ConnectorExpression` pushdown trees → Trino `TupleDomain` (EQ / range / NE / IN / IS [NOT] NULL / AND / OR, Slice encoding), plus graceful degradation to `TupleDomain.all()` on null/unsupported input. - `TrinoTypeMappingTest` — Trino SPI type → Doris `ConnectorType` (scalars, decimal precision/scale, timestamp precision clamp, array/map/struct, unsupported-type failure). - `TrinoConnectorProviderTest` — `validateProperties` fast-fails when `trino.connector.name` is missing/empty. - No Trino plugin/cluster required; plugin-dependent paths remain covered by the existing `external_table_p0/p2` `trino_connector` regression suites. - Sync the migration tracking docs under `plan-doc/` (already carried on this feature branch since P0). **Net effect**: 28 files, +1025 / −2681 (~1656 LOC net removed). Old FE images holding legacy trino catalogs / databases / tables deserialize onto the `PluginDrivenExternal*` hierarchy through the GsonUtils string-name redirect, with engine-name display preserved. **Deferred (follow-ups, not in this PR)**: - `trino_connector_migration_compat` regression test (old-image deserialization) — requires a running cluster + Trino plugin + docker, unavailable in this dev environment; tracked as a CI/cluster follow-up. - The plugin-install documentation update lives in the `doris-website` repo and is handled separately. ### Release note None ### Check List (For Author) - Test - [x] Unit Test — 29 new tests in `fe-connector-trino` (predicate converter / type mapping / property validation). - [ ] Regression test — existing `trino_connector` suites cover plugin paths; the new old-image compat regression is deferred to a CI/cluster follow-up. - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test. Explain why: - [ ] This is a refactor/code format and no logic has been changed. - [ ] Previous test can cover this change. - [ ] No code files have been changed. - [ ] Other reason - Behavior changed: - [x] No. Internal routing moves from the legacy fe-core path to the SPI path; image compatibility, engine-name display, and pushdown semantics all mirror the legacy behavior. All batches land together, so there is no serialization-gap window. - Does this need documentation? - [x] Yes. The trino-connector plugin-install doc update is a follow-up in the `doris-website` repo. ### Check List (For Reviewer who merge this PR) - [ ] Confirm the release note - [ ] Confirm test cases - [ ] Confirm document - [ ] Add branch pick label --- .../doris/connector/trino/TrinoBootstrap.java | 51 +- .../trino/TrinoConnectorDorisMetadata.java | 137 +++- .../trino/TrinoConnectorProvider.java | 11 + .../connector/trino/TrinoDorisConnector.java | 15 +- .../trino/TrinoScanPlanProvider.java | 73 +- .../connector/trino/TrinoBootstrapTest.java | 70 ++ .../trino/TrinoConnectorProviderTest.java | 61 ++ .../trino/TrinoPredicateConverterTest.java | 239 ++++++ .../connector/trino/TrinoTypeMappingTest.java | 141 ++++ fe/fe-core/pom.xml | 4 - .../connector/DefaultConnectorContext.java | 4 + .../doris/datasource/CatalogFactory.java | 9 +- .../doris/datasource/ExternalCatalog.java | 3 +- .../PluginDrivenExternalCatalog.java | 15 +- .../datasource/PluginDrivenExternalTable.java | 6 + .../TrinoConnectorExternalCatalog.java | 329 -------- .../TrinoConnectorExternalCatalogFactory.java | 30 - .../TrinoConnectorExternalDatabase.java | 37 - .../TrinoConnectorExternalTable.java | 263 ------- .../TrinoConnectorPluginLoader.java | 134 ---- .../trinoconnector/TrinoSchemaCacheValue.java | 90 --- .../TrinoConnectorPredicateConverter.java | 334 -------- .../source/TrinoConnectorScanNode.java | 342 -------- .../source/TrinoConnectorSource.java | 106 --- .../source/TrinoConnectorSplit.java | 95 --- .../translator/PhysicalPlanTranslator.java | 5 - .../apache/doris/persist/gson/GsonUtils.java | 18 +- .../TrinoConnectorPredicateTest.java | 736 ------------------ plan-doc/HANDOFF.md | 207 ++--- plan-doc/PROGRESS.md | 38 +- plan-doc/connectors/trino-connector.md | 65 +- plan-doc/deviations-log.md | 61 +- .../tasks/P2-trino-connector-migration.md | 197 +++++ 33 files changed, 1212 insertions(+), 2714 deletions(-) create mode 100644 fe/fe-connector/fe-connector-trino/src/test/java/org/apache/doris/connector/trino/TrinoBootstrapTest.java create mode 100644 fe/fe-connector/fe-connector-trino/src/test/java/org/apache/doris/connector/trino/TrinoConnectorProviderTest.java create mode 100644 fe/fe-connector/fe-connector-trino/src/test/java/org/apache/doris/connector/trino/TrinoPredicateConverterTest.java create mode 100644 fe/fe-connector/fe-connector-trino/src/test/java/org/apache/doris/connector/trino/TrinoTypeMappingTest.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/TrinoConnectorExternalCatalog.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/TrinoConnectorExternalCatalogFactory.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/TrinoConnectorExternalDatabase.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/TrinoConnectorExternalTable.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/TrinoConnectorPluginLoader.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/TrinoSchemaCacheValue.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/source/TrinoConnectorPredicateConverter.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/source/TrinoConnectorScanNode.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/source/TrinoConnectorSource.java delete mode 100644 fe/fe-core/src/main/java/org/apache/doris/datasource/trinoconnector/source/TrinoConnectorSplit.java delete mode 100644 fe/fe-core/src/test/java/org/apache/doris/datasource/trinoconnector/TrinoConnectorPredicateTest.java create mode 100644 plan-doc/tasks/P2-trino-connector-migration.md diff --git a/fe/fe-connector/fe-connector-trino/src/main/java/org/apache/doris/connector/trino/TrinoBootstrap.java b/fe/fe-connector/fe-connector-trino/src/main/java/org/apache/doris/connector/trino/TrinoBootstrap.java index 3b7d4892a2dfbc..eecb8078cddb56 100644 --- a/fe/fe-connector/fe-connector-trino/src/main/java/org/apache/doris/connector/trino/TrinoBootstrap.java +++ b/fe/fe-connector/fe-connector-trino/src/main/java/org/apache/doris/connector/trino/TrinoBootstrap.java @@ -144,6 +144,21 @@ public static TrinoBootstrap getInstance(String pluginDir) { return instance; } + /** + * Returns the already-initialized singleton.

-继承前一版认知。**本场新增**： +## ⚠️ 关键认知 / 临时发现 -1. **`tools/check-connector-imports.sh` 是一个隐含的设计约束** — fe-core 不能 import fe-connector 内部类（`org.apache.doris.connector.*`），所以"复用"SPI 实现唯一通道是 `ConnectorPlugin` 接口。批 B 直接 import `JdbcConnectorClient` 替换 `JdbcClient` 本能解法**走不通**——一定要经过 SPI capability 扩展。这条约束以前 P0 文档讲过，但批 B recon 时是第一次真正触发它 -2. **CDC streaming 是 SPI 未覆盖的 use case** — 现有 SPI（ConnectorMetadata.getTable / listTables / getTableHandle）是面向"标准 SELECT"的，没暴露 PK 探测、columns-from-jdbc-driver、replication-slot 校验。P8 启动前需要先在 RFC 中起 §17 章节描述这套扩展，否则 P8 实施会 stall -3. **fe-connector 侧的 `Jdbc*ConnectorClient` 是 P0 阶段 JDBC 迁移的产物** — 它们没有暴露 PK / column-from-driver 接口（按 ConnectorMetadata 标准抽象设计），所以即便允许 fe-core 直接 import 也不能直接替换 legacy client。换言之 SPI 设计本身需要扩展（不只是 "改 import 路径"） +1. **rebase 后 fe-core 编译坑（非代码问题）**：本场最大时间消耗。rebase 拉入 `#63823`（nereids 语法从 fe-core 拆到新模块 `fe-sql-parser`）后，`fe-core/target/generated-sources/.../DorisParser.java` 旧生成物残留（git 不管 target/），FQCN 撞名盖过 fe-sql-parser 依赖里的新版 → `LogicalPlanBuilder` 报 `cannot find symbol HOT()/expression()`。**修法：`clean` fe-core**（旧生成物删除、fe-core 已无 grammar 不会再生成）。只 clean fe-sql-parser 不够。任何 rebase 后遇此症状先 clean fe-core，别当代码 bug 查。 +2. **`MetastoreProperties` trino 条目有意保留**：它在 `property/metastore/` 子系统、不引用被删目录、删之不影响编译，但 SPI 建 catalog 可能仍走它解析属性。批 D 不动它；是否死代码留待后续评估（DV-001 后续动作）。 +3. **docs-next 不在本代码仓**：用户向文档在 doris-website 仓（DV-004）。本仓只有 `docs/`。 +4. （沿用）`tools/check-connector-imports.sh` import gate：fe-core 不能 import `org.apache.doris.connector.*`。 +5. （沿用）P1 fallback：`PhysicalPlanTranslator` 里其余 6 个连接器的 instanceof 分支待 P3-P7 各自迁完时删；本场只清了 trino 那一支（T08）。 --- ## 🎯 下一个 session 第一件事 -> P1 已关闭。下一阶段 P2 (trino-connector，2 周)。**预备动作**：先把批 A push + PR，再做 P2 recon。 -

(Rayner)" Date: Sat, 6 Jun 2026 10:34:04 +0800 Subject: [PATCH 005/128] [feat](connector) P3 hudi connector hardening + test baseline + dispatch design (hybrid, T02-T08) (#64143) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Proposed changes testing with #64146 P3 of the catalog-SPI migration (base: `branch-catalog-spi`). Migrates the **hudi** connector following the **hybrid** strategy (D-019): harden the dormant HMS-over-SPI hudi connector to correctness parity, build a test baseline, and write the per-table dispatch design — **all behind the closed gate** (`SPI_READY_TYPES` unchanged). > ⚠️ **No user-visible behavior change.** The SPI hudi path stays dormant (gate closed); hudi queries continue to use the legacy `HMSExternalTable.dlaType=HUDI` path. This PR removes correctness blockers ahead of the live cutover (deferred to P7 / batch E). ### What's included **Correctness fixes (hardening dormant code, behind gate):** - **T02** — fix hudi JNI `column_types` double bug: emit full Hive type strings (was Doris bare type names, losing precision/scale/subtypes) and send `column_names`/`column_types`/`delta_logs` as typed lists end-to-end (was comma join/split, which shattered `decimal(10,2)` / `struct<...>`). Matches the BE `hudi_jni_reader.cpp` contract (names `,` / types `#` / delta `,`). - **T04** — fail loud on time-travel / incremental read in the SPI `visitPhysicalHudiScan` branch (was silently returning the latest snapshot / silently full-scanning). - **T05** — real EQ/IN partition pruning in `HudiConnectorMetadata.applyFilter` (was a placeholder that ignored predicates and unconditionally switched the partition source from Hudi-metadata to HMS); faithfully mirrors `HiveConnectorMetadata.applyFilter`. - **T07** — column-name casing fix in `avroSchemaToColumns` (top-level lowercase, mirroring legacy `HMSExternalTable`). **Test baseline (all three connector modules started P3 with 0 tests):** - `fe-connector-hudi` (33): type-mapping / schema-parity (COW/MOR golden) / table-type / partition-pruning / scan-range. - `fe-connector-hms` (12): shared Hive-type-string parser tests. - `fe-connector-hive` (14): file-format / partition-pruning (mirrors T05). - COW/MOR schema is **type-agnostic** (golden parity vs legacy `initHudiSchema`); table type only affects scan planning. **Decisions / design (code-grounded, design-only):** - **T03** — defer `schema_id`/`history_schema_info` field-id evolution to batch E (DV-006; not a model-agnostic SPI fix). - **T06** — keep MVCC/snapshot SPI defaults (opt-out) + document (DV-007). - **T08** — `tableFormatType` dispatch design memo + **D-020**: single `hms` catalog per-table routing via a new backward-compatible `ConnectorMetadata.getScanPlanProvider(handle)` (per-table provider seam); refines D-005. The keystone gap is split into M1 (identity consumption, fe-core reads `tableFormatType` as an opaque string) and M2 (scan routing). ### Deferred to batch E / P7 (not in this PR) Gate flip (`SPI_READY_TYPES += hms/hudi`), fe-core `tableFormatType` consumption (M1+M2 implementation), live cutover, delete legacy `datasource/hudi/`, full incremental/time-travel/MVCC, Iceberg-on-hms via SPI (needs P6 `IcebergScanPlanProvider`), cluster/runtime validation. ### Verification Per task tracking, each code batch landed with: per-module compile + checkstyle 0 (incl. test sources) + connector import-gate pass + new unit tests green. The two most recent commits are docs-only (`plan-doc/`); the code is unchanged since the last green batch. Gate stays closed → the dormant SPI path is unreachable at runtime → zero live-path risk.

fe-core，不动 BE，不动 thrift**），gate 保持关闭。 + +### 改动 1 — `HudiTypeMapping.java`：新增 Avro→Hive 类型串方法 + +新增 `public static String toHiveTypeString(Schema schema)`，**逐行 mirror** legacy `HudiUtils.convertAvroToHiveType`（fe-core，import gate 禁止直接复用，故在连接器模块内复刻）。语义完全对齐，包括： +- `decimal(p,s)`、`array<...>`、`struct`、`map`、`timestamp`/`date`、primitives； +- UNION 单一非空类型递归 unwrap； +-

上报（`HudiConnectorMetadata.java:240`），是正确的、另一条路径。 + +### 改动 2 — `HudiScanPlanProvider.java`：用 Hive 类型串生成 column_types + +`planScan` 中 column_types 生成（:118-120）： +```java +// before +columnTypes = avroSchema.getFields().stream() + .map(f -> HudiTypeMapping.fromAvroSchema(unwrapNullable(f.schema())).getTypeName()) + .collect(Collectors.toList()); +// after +columnTypes = avroSchema.getFields().stream() + .map(f -> HudiTypeMapping.toHiveTypeString(f.schema())) + .collect(Collectors.toList()); +``` +（`toHiveTypeString` 自己处理 union unwrap，直接传 `f.schema()`，对齐 legacy `convertAvroToHiveType(field.schema())`。）若此改动使私有 `unwrapNullable`（:350-359）变为未引用，则一并删除。 + +### 改动 3 — `HudiScanRange.java`：三个 list 字段端到端 typed，弃逗号 join/split + +- 新增三个 `List` 字段：`deltaLogs`、`columnNames`、`columnTypes`（不可变副本）。 +- 构造器：**移除** `props.put("hudi.delta_logs"/"hudi.column_names"/"hudi.column_types", String.join(",", ...))`（:88-96 三处），改为赋值字段。标量 JNI

仅被 `HudiScanRange.populateRangeParams` 自身消费（`PluginDrivenScanNode.java:392` 调 `populateRangeParams`，且 `HudiScanRange` override 了该方法、不走 `ConnectorScanRange` 默认 generic 路径）——故三个 list key 从 map 移除对外部零影响。 + +--- + +## Implementation Plan + +1. `HudiTypeMapping.java`：加 `toHiveTypeString(Schema)` + 递归 helper（mirror legacy）。 +2. `HudiScanPlanProvider.java`：改 :118-120；若 `unwrapNullable` 变 dead 则删。 +3. `HudiScanRange.java`：加 3 字段、改构造器、改 `populateRangeParams`。 +4. 新增单测（见下）。 +5. 构建守门：`mvn -pl fe-connector/fe-connector-hudi -am test -Dmaven.build.cache.enabled=false

caller**（trino-connector 之外的 SPI 表才会触达，hudi 未翻闸）。改动纯属硬化 dormant 代码，**零 live-path 风险**。 +- **契约风险**：BE↔Java 的 `#`/`,` 分隔已两点确认；不改 BE/thrift，契约不变。 +- **parity 残留（不在 T02 范围，登记）**： + - column_names/types

`toHiveTypeString` 对不支持类型抛异常，会被上述 try/catch 吞 → 同属 T04 范畴。 +- **simplicity（CLAUDE.md R2/R3）**：仅 3 文件、新增一个 mirror 方法 + 字段化三个 list；标量保持原样，最小 diff。 + +--- + +## Test Plan + +### Unit Tests（本 task 交付；建立 fe-connector-hudi 首个测试） + +`HudiTypeMappingTest`（验证 Avro→Hive 串编码意图，Rule 9）： +- `decimal` logical type → `"decimal(10,2)"`（**精度/scale 不丢** —— 直击 bug a）。 +- record → `"struct"`（**含逗号的复杂类型** ——

2001 From: "Mingyu Chen (Rayner)" Date: Tue, 9 Jun 2026 17:23:08 +0800 Subject: [PATCH 006/128] [refactor](connector) P4 maxcompute: remove legacy subsystem from fe-core + make fe-core odps-free (T07-T09) (#64300) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-up to #64253 (the MaxCompute catalog-SPI cutover). After the cutover a `max_compute` catalog deserializes to `PluginDrivenExternalCatalog` and no legacy `MaxComputeExternal*` object is ever instantiated, so the legacy MaxCompute subsystem in fe-core is dead code. This removes it and makes fe-core's dependency tree fully odps-free. **1. Remove legacy subsystem** (`7a4db351100`) - Delete 20 fe-core files: `datasource/maxcompute/*` (incl. `MCTransaction`, `MaxComputeScanNode`/`Split`), the MaxCompute sink/insert/txn plumbing, and 2 legacy-only tests. - Clean ~21 reverse-reference sites (imports + dead `instanceof`/visitor/rule branches), keeping every `PluginDriven`/connector sibling branch and the image/replay keep-set (GsonUtils compat strings; `TableType`/`TransactionType`/`TableFormatType`/`InitCatalogLog.Type` `MAX_COMPUTE` enums; block-id thrift). - Rewire 3 tests; e.g. `FrontendServiceImplTest`'s block-id RPC test now mocks the generic `Transaction` SPI, since `getMaxComputeBlockIdRange` reads the PluginDriven connector transaction. **2. Make fe-core odps-free** (`409300a75b8`) - Drop the two odps deps from `fe-core/pom.xml`. - Move `MCUtils` from fe-common into `be-java-extensions/max-compute-connector` (its only consumer after the removal); keep `MCProperties` (odps-free constants) in fe-common. - Drop `odps-sdk-core` from fe-common — it was also leaking netty/protobuf transitively to fe-common's own `DorisHttpException`/`GsonUtilsBase`, so declare `netty-all` + `protobuf-java` directly (proper dependency hygiene). **3. Doc-sync** (`f8c305765e8`) — plan-doc PROGRESS/HANDOFF/deviations/design tracking notes. - `mvn -pl :fe-core -am test-compile` (main+test) passes; checkstyle 0 violations; connector import-gate passes. - `grep -rn com.aliyun.odps fe/fe-core/src` → empty. - `mvn -pl :fe-core dependency:tree | grep odps` → empty (no odps, direct or transitive). 🤖 Generated with [Claude

+ * + *

Boundary: this connector module has no fe-core dependency, so the test can only assert the + * override's OWN output. It cannot reach the fe-core {@code toThrift} call site (passing remote + * dbName/remoteName, numCols) — that half of the contract is covered by user-run e2e only.

WHY this matters: BE has no {@code split_type} field on the wire — it classifies a + * MaxCompute split purely by the numeric {@code split_size} it receives. {@code MaxComputeJniScanner} + * does {@code if (splitSize == -1) BYTE_SIZE else ROW_OFFSET} (MaxComputeJniScanner.java:125-128), + * then in {@code open()} builds {@code IndexedInputSplit} (BYTE_SIZE) or + * {@code RowRangeInputSplit(sessionId, startOffset, splitSize)} (ROW_OFFSET). If a byte_size split + * carries a real byte count (e.g. 268435456) instead of {@code -1}, BE silently mis-reads it as a + * ROW_OFFSET split and returns CORRUPT data (no error). So the provider's byte_size branch MUST emit + * size {@code -1}; this mirrors legacy {@code MaxComputeScanNode}'s + * {@code MaxComputeSplit(..., length=-1, fileLength=splitByteSize, ...)}.

+ * + *

This test drives the PROVIDER's real byte_size split-building code + * ({@code buildSplitsFromSession}) with offline fakes (no network, no live ODPS) — so it locks the + * provider's CHOICE of {@code -1}, not merely the range mechanism. Reverting the byte_size branch to + * {@code .length(splitByteSize)} makes {@code byteSizeBranchEmitsMinusOneSizeSentinel} FAIL + * (getSize() would become the real byte size). The row_offset case is the contrast that proves only + * byte_size uses the sentinel — its size is the real row count, never {@code -1}.

+ * + *

The connector module has no fe-core / Mockito; we reach the private split-building method via + * reflection and stub the ODPS {@code TableBatchReadSession} / {@code InputSplitAssigner} with plain + * Serializable fakes ({@code serializeSession} writes the session, so it must be Serializable).

In production the connector runs inside {@code ConnectorPluginManager}'s plugin isolation, + * where {@code org.apache.doris.connector.} / {@code org.apache.doris.filesystem.} are parent-first + * (the shared SPI) while the connector impl and its third-party deps — including the ODPS SDK + * ({@code com.aliyun.odps.*}) — load child-first, getting an isolated copy per plugin. Risk R-004 is + * that loading the ODPS SDK in such isolation breaks (NoClassDefFoundError / ClassCastException) or + * that a per-plugin SDK copy poisons a process-wide singleton.

+ * + *

新结论】keystone gap = M1（身份消费）⊥ M2（scan 路由），可分离 -- `tableFormatType` **产而不用**：`HiveConnectorMetadata.getTableSchema` 设了它，但 `PluginDrivenExternalTable.initSchema:79-109` **只读 `getColumns()`**、丢 `getTableFormatType()`（本 session firsthand 核读确认）。第二缺口：`getEngine:195-215`/`getEngineTableTypeName:217-231` switch **catalog type** 非 per-table format。 -- **M1**（fe-core 读格式做 per-table 引擎名/身份，**opaque 串、热路径不读**）在 A/B/C **三方案通用**；**M2**（单 hms connector 产 Hudi/Iceberg scan plan）才是 A/B/C 分歧处。→ keystone 可控化。 -- **M2 = 方案 B**（[D-020]，用户签字）：新增向后兼容 default `ConnectorMetadata.getScanPlanProvider(handle)`（默认 null→回落 per-catalog `Connector.getScanPlanProvider()`），fe-core `PluginDrivenScanNode.getSplits` 优先 per-table、回落 per-catalog。前提：`ConnectorScanPlanProvider.planScan:62-66` 入参已带 per-table handle（本 session 核实）。**A 备选**（连接器内 router，零 SPI churn）；**C 否决**（fe-core 长格式分派，违瘦 fe-core）。 -- **D-020 细化 D-005**（非推翻）：tableFormatType 区分符沿用；D-005 的"fe-core→PhysicalXxxScan"措辞早于 P1 scan-node 统一，由 per-table provider seam 取代。**批 E 实现别按 D-005 旧措辞做 PhysicalXxxScan**。 +> **用户原话**：确认所有 maxcompute 的操作，都走到新的 SPI 框架上，不允许回退到老的代码上。 -### 2.【批 C 已用，批 E 仍需】parity 可行性 = golden-value（无跨模块编译路径） -- `fe-core` 只依赖 `fe-connector-api` + `fe-connector-spi`，**不依赖**具体 `-hudi`/`-hms`/`-hive` 模块；连接器模块不依赖 fe-core。import-gate（`tools/check-connector-imports.sh`）**只扫 `*/src/main/java`、只禁 connector→fe-core 单向**（test 豁免，但无编译路径仍使跨模块 parity 不可行）。 -- → legacy↔SPI parity 用 **golden 值**（注 legacy `file:line`）。测试栈 **JUnit5 only，无 mockito**，替身手写（`FakeHmsClient` 先例）。checkstyle **含 test 源**（`fe/pom.xml:162`）、**禁 static import**（用 `Assertions.assertX`）、**test 阶段不跑 checkstyle** → 单独 `mvn -pl checkstyle:check`。 +**目标**：对 `max_compute` catalog 的**每一类操作**，证 FE 分发可达新 SPI/PluginDriven 实现，且 legacy `MaxCompute*` 对应路径在运行时**零可达**（无静默回退）。= 🅱 Batch-D 删 legacy 的**静态前置确认**（零可达调用方 → 删除才安全）。 -### 3.【批 C 关键结论】COW/MOR schema = type-agnostic -- legacy `HMSExternalTable.initHudiSchema` 与 SPI `HudiConnectorMetadata.getTableSchema`→`avroSchemaToColumns` 都从**同一 avro schema** 推导列表，**零表型分支**。COW/MOR 区别**只在 scan planning**（`HudiScanPlanProvider.planScan:92`：COW=base files native、MOR=merged slices + delta logs JNI）。→ schema parity 是 avro→column 纯函数；表型只影响 `detectHudiTableType` + split 收集。 +**审计范围（逐类核「FE 入口 → SPI 路由」+「legacy 路径零可达」）**： +- 读：scan / 分区裁剪(P1-4) / 谓词下推(G0/G2) / limit-split(P3-9) / batch-mode(P3-11) / CAST 剥壳(F9)。 +- 写：INSERT / INSERT OVERWRITE(P0 gate) / 事务 begin·commit·block-alloc(GC1) / sink

isKey(P3-10) / SHOW PARTITIONS / partitions() TVF。 -### 4.（沿用）SPI 分区裁剪链路 + Hive parity 基准（T05） -- `PluginDrivenScanNode.applyFilter`→`currentHandle`→`getSplits`→`HudiScanPlanProvider.resolvePartitions` 读 `getPrunedPartitionPaths()`。Hudi `applyFilter` 镜像 `HiveConnectorMetadata.applyFilter`（7 步 + 7 helper duplicate，hudi 仅依赖 fe-connector-hms）。 +**已知风险区（必查、勿信先验「已修」标签 — Rule 8/12）**： +- ⚠️ **FE 分发缺口** [[catalog-spi-cutover-fe-dispatch-gap]]：`PluginDrivenExternalCatalog` 仅 override

`plan-doc/reviews/P4-maxcompute-full-rereview-2026-06-07.md`）→ 必须逐路径重核，不得信任何「已修」标签。 +- legacy 删除候选逐个确认对 `max_compute` **零运行时可达调用方**：`MaxComputeExternalCatalog` / `MaxComputeScanNode` / `MaxComputeMetadataOps` / `MCTransaction` / `PhysicalMaxComputeTableSink` / `bindMaxComputeTableSink` / `allowInsertOverwrite` 的 MC 分支 / `MaxComputeExternalTable`。 +- 「分发只接一半」反模式（已多次踩：P0 overwrite 顶层网关挡死下层；FE 仅 override createTable）：每个 op 须核**完整**分发链，非仅「连接器实现存在」。 -### 5.（沿用）BE Hudi JNI column_types/names/delta 契约（T02） -- `THudiFileDesc.{delta_logs,column_names,column_types}` thrift `list`；**BE 自做 join**：names `,` / types **`#`** / delta `,`（`hudi_jni_reader.cpp:52-54`）。FE 传 typed list、类型串用 Hive 串（`HudiTypeMapping.toHiveTypeString`，非 `getTypeName()`）。 +**成功标准（Rule 4，强标准供独立 loop）**：产出审计报告（建议 `plan-doc/reviews/P4-cutover-completeness-audit-.md`）——每 op 一行：路由✅(FE 入口→SPI 实现 file:line) / 回退⚠️(file:line + 判据)；任何回退/缺口登记为新 gap 进 `plan-doc/task-list-batchD-redline-gaps.md` 修复。**法**：grep + 调用链

端类型混淆下整体不可用,且写/DDL/分区在若干用户可见维度存在回归。"gate-green / flip only changes dispatch / 读路径已通"这三条历史核心论断在代码层面均不成立。** + +## 一、Top 问题(按 severity) + +### Blocker(翻闸后即坏,必须修) + +1. **读取描述符类型混淆(READ-P1 / READ-C1)** — PluginDriven MaxCompute 的 `toThrift` 走 null 兜底产出 `SCHEMA_TABLE` 描述符且不含 `TMCTable`,但 BE `file_scanner.cpp` 在 `table_format_type=="max_compute"` 时无条件 `static_cast` 到 `MaxComputeTableDescriptor*`,造成非法向下转型,endpoint/quota/project/凭证全为越界/垃圾内存、无鉴权。**重要性**:读路径整体不可用,SELECT 必崩或返回错误数据。**回归:是**。根因是 `MaxComputeConnectorMetadata` 缺 `buildTableDescriptor` override。 + +2. **byte_size split size 误填(READ-P2)** — 默认 split 策略下 `rangeDesc.size=splitByteSize`(应为 `-1` sentinel),BE 据 `size==-1` 区分 BYTE_SIZE/ROW_OFFSET,误把 byte-size split 当 row-offset split → 损坏读取。**重要性**:即便绕过 blocker 1,默认路径仍读出错误数据。**回归:是**。 + +3. **无 ENGINE 子句的 CREATE TABLE 分析期报错(DDL-P1)** — `paddingEngineName` 只认 `MaxComputeExternalCatalog`,翻闸后 catalog 是 `PluginDrivenExternalCatalog` → 落 else 分支抛 `Current catalog does not support create table`,根本到不了 override。**重要性**:legacy 可用、翻闸即坏的 CREATE TABLE 子场景,且是 T06c 矩阵漏标(矩阵把 CREATE TABLE 一律标 PASS)。**回归:是**。 + +### Major(语义/可观察行为偏离,多数应修) + +4. **分区裁剪整体丢失(READ-P3 / READ-C2 / CACHE-C-SELECT)** — `PluginDrivenExternalTable` 不暴露任何分区 API(`supportInternalPartitionPruned`/`getPartitionColumns`/`getNameToPartitionItems` 全默认),connector 又恒传 `requiredPartitions=emptyList` → 大分区表退化整表扫,仅靠易整体回退的 ODPS filter 兜底。**回归:是**。 + +5. **partitions() TVF 与 SHOW PARTITIONS 仍被 FE 门禁挡死(DDL-C1 / CACHE-C1 / CACHE-C2)** — T06c 只接了 BE 取数支路(`MetadataGenerator`),`PartitionsTableValuedFunction.analyze` 的 catalog/table 类型 allow-list 与 `ShowPartitionsCommand` 的 `isPartitionedTable()` 门未接 → 这两条命令在 analyze 期即抛错,已接好的 BE handler 是不可达死代码。**回归:是**。 + +6. **DDL 远端名解析丢失(DDL-P3 / DDL-C2)** — CREATE/DROP TABLE 用本地名直发 ODPS SDK,丢了 legacy 的 `getRemoteName()` 映射;在 `lower_case_meta_names` / `meta_names_mapping` 生效时建错库、删错/找不到表。**回归:是(数据正确性)**。 + +7. **DROP DATABASE FORCE 级联静默丢弃(DDL-P2 / DDL-C3)** — force 不转发,直发 `schemas().delete`;ODPS 常拒删非空 schema → legacy FORCE 成功而翻闸失败/留残表。**回归:是(待真实 ODPS 确认非空库删除行为后定级)**。 + +8. **INSERT 影响行数恒为 0(WRITE-P1 / WRITE-C1)** — `doBeforeCommit` 在 txn 模型分支被跳过,丢了 legacy 的 `loadedRows = transaction.getUpdateCnt()` 一行;数据写对,但客户端/SHOW INSERT RESULT/audit 报 `affected rows: 0`。**重要性**:可观察输出回归,且 `getUpdateCnt` 链路已实现、只差一行赋值。**回归:是**。 + +9. **datetime 谓词下推损坏 + 源时区错(READ-P4 / READ-C3)** — `LocalDateTime.toString()` 产 ISO-8601,被 `yyyy-MM-dd HH:mm:ss.SSS` formatter 解析失败 → 谓词被静默吞成 NO_PREDICATE;且源时区取 endpoint region 而非会话时区。**回归:是**。 + +10. **limit-split 优化无条件触发(READ-P5 / READ-C4)** — 忽略 `enable_mc_limit_split_optimization`(默认 OFF),且分区等值场景永不触发;默认行为与 legacy 相反。**回归:是**。 + +11. **DDL 列约束/本地校验丢失(DDL-P4 / DDL-C6)** — `ConnectorColumn` 不携带 auto-increment / 聚合标志,legacy 的拒绝校验被静默绕过;本地 db 存在校验亦缺失。**回归:是(静默丢语义)**。 + +12. **CAST 谓词下推语义不同(READ-C6)** — 翻闸默认剥离 CAST 把内层比较下推 ODPS,legacy 遇 CAST 保守不下推;有产生错误结果的风险。**回归:unsure**(需端到端核实)。 + +### Minor(窄口径差异,可接受但应登记) + +- **block 上限硬编码 20000(WRITE-P2 / WRITE-C2)** — 忽略可配置 `Config.max_compute_write_max_block_count`,仅运维调大时差异。**回归:是**。 +- **isKey 标记不同(READ-C7)** — data 列 legacy `isKey=true`,翻闸 `false` → DESCRIBE/information_schema 列属性差异。**回归:是**。 +- **CREATE TABLE IF NOT EXISTS 命中已存在表仍写 editlog + 刷缓存(DDL-C5)** — SPI 返回 void 无法区分新建/已存在,legacy 为 no-op。**回归:是**(冗余 editlog,不阻塞)。 +- **master 侧 editlog 与 cache 失效顺序反转(REPLAY-P1 / REPLAY-C1)** — 同 FE 本地同步,无可观察后果。**回归:否**。 +- **FE 侧 partition_values 二级缓存成死代码(CACHE-P1)** — 改为每查询直连 ODPS 列举分区,从一致性看更安全但多一次 round-trip。**回归:unsure(性能)**。 +- **split 缺 FILE_NET / fileSize / modificationTime(READ-C8)**;**post-commit 缓存刷新异常翻闸吞错而 legacy 抛错(WRITE-P3 / WRITE-C3)** — 后者实为改进(legacy 报失败会诱导重复写),但属可观察行为变更,应登记。 + +### 经核实属"翻闸更正确"的项(应作为回归基线,勿误判为差异) + +- **IN/NOT IN 取反 bug(READ-C9)** — legacy 把 NOT IN 下推为 ODPS IN(漏数据),翻闸修正了取反。**回归:否(有意修正)**,回归用例须以正确语义为基线。 + +## 二、与历史结论最关键的分歧 + +本轮基于代码**明确不认同**以下"历史认为没问题/已解决"的判定: + +1. **"翻闸后 read/write/DDL/partition/show 全经 SPI 正常工作""flip only changes dispatch"** — `route through the SPI` 仅在 dispatch 层成立,语义层不成立。读路径有 2 个 BE 端 blocker(描述符类型混淆、split size 误填)+ 分区裁剪丢失 + 多处下推语义偏离。**gate(compile/checkstyle/单测)从不覆盖 BE thrift 描述符类型、split 语义、与 legacy 的下推 parity,故 "gate-green" 不构成读 parity 证据**——该风险被错误标为"已缓解"。 + +2. **HANDOFF live 矩阵 "SELECT(含分区裁剪)✅ PASS / 读路径已通"** — 该 PASS 缺 BE 端与分区裁剪的核实。trino 路径验证的只是 split→BE 的通用 plumbing,不代表 MC 读语义正确;MC 在描述符类型混淆下拿不到凭证。 + +3. **"T06c 已把 partitions() TVF 的 FE 分发接到 SPI"(commit 2cf7dfa81ad ③,HANDOFF/设计标 ✅)** — **证伪**。`git show --stat` 显示该 commit 只改 `MetadataGenerator.java`,从未触碰 `PartitionsTableValuedFunction.java`;全文 grep 无 `PluginDrivenExternalCatalog` 分支。`dealPluginDrivenCatalog` 是不可达死代码,该 TVF 对翻闸后 MC 仍 100% FAIL。 + +4. **Batch D 设计的危险 amendment** — 其声称"T06c 已在 `PartitionsTableValuedFunction` 加 PluginDriven 分支,Batch D 应删 :173 的 MaxCompute 分支"。前提是错的:文件里根本没有该分支。**若按它执行删除,会删掉该 TVF analyze 唯一的非-Plugin 放行分支,使 partitions() 对 MC 永久不可用——正是 amendment 自称要防止的场景被它自己触发。** + +5. **"SHOW PARTITIONS 翻闸后可用(T06c 已接线,live 全绿)"** — 部分证伪。T06c 修了 allow-list/表类型/dispatch/handler,但漏了 `analyze()` 的 `isPartitionedTable()` 门;`PluginDrivenExternalTable` 未 override 该方法(default false)→ 真实分区表先抛"is not a partitioned table",新 handler 对分区表成死代码。设计 §4.3 把 `isPartitionedTable` 标"验证项"却未实现,却标全绿。 + +6. **"无 ENGINE 的 CREATE TABLE PASS"** — 矩阵不完整。`paddingEngineName` 在分析期即抛错,是 T06c 范围外、HANDOFF 与设计均未识别的 blocker 级回归。 + +7. **"doBeforeCommit 在 MC 路径被跳过是正确的,镜像 legacy MCInsertExecutor"** — 不认同。跳过会丢 legacy 的 `loadedRows = getUpdateCnt()`(load-bearing 一行);设计的 G1–G5 gap 与风险表只覆盖"能否写成功",完全没覆盖"写成功后报告的行数",loadedRows 是被设计遗漏的独立 gap。 + +8. **"DDL 远端名经连接器内部解析 remote 映射"(T06c 设计假定)** — 与代码相反。`MaxComputeConnectorMetadata` 的 `getTableHandle`/`createTable`/`dropTable` 都把本地名原样喂给 SDK,零 local→remote 解析。 + +9. **"DROP DATABASE FORCE 级联不复刻可接受(记 OQ)"** — 不认同其"可接受"定级;这是用户可见的 DDL 语义回归(major),不应在设计 §5 一笔带过。 + +10. **"A1 缓存失效全对齐 legacy 行为"** — 对齐了"是否失效"与 master/follower parity,但 master 侧 editlog 与 cache 失效的执行顺序被反转(legacy 先失效后写日志,翻闸相反)。判定无可观察回归,但"完全对齐"措辞不严谨,存在未记录的副作用顺序反转(Rule 12 fail loud)。 + +## 三、建议的后续动作(供决策) + +### A. live 验证 / Batch D 删除前**必须修复**(blocker + 阻断核心 DDL) + +- **READ-P1/C1**:为 `MaxComputeConnectorMetadata` 补 `buildTableDescriptor` override,产出 `MAX_COMPUTE_TABLE` + `TMCTable`(endpoint/quota/project/table/properties 含 time_zone),对齐 legacy `toThrift`。这是读路径能否工作的总开关。 +- **READ-P2**:byte_size split 回填 `rangeDesc.size=-1` sentinel,恢复 BE 的 BYTE_SIZE/ROW_OFFSET 判别。 +- **DDL-P1**:`paddingEngineName` / `checkEngineWithCatalog` 识别 `PluginDrivenExternalCatalog`(按 `getType()=="max_compute"` 或 connector 声明的 engine)。 +- **DDL-C1 / CACHE-C1 / CACHE-C2**:补 `PartitionsTableValuedFunction.analyze` 的 catalog/table allow-list、`ShowPartitionsCommand` 的 `isPartitionedTable()` 门,并让 `PluginDrivenExternalTable` override `isPartitionedTable`/`getPartitionColumns`/`getNameToPartitionItems`,打通已接好的 BE handler。 +- **⚠️ Batch D 红线**:**不要**按 Batch D 设计删除 `PartitionsTableValuedFunction:173` 的 MaxCompute 分支——该 amendment 前提错误,执行会使 partitions() 对 MC 永久不可用。删除前先在代码确认 PluginDriven 分支确已存在。 +- **DDL-P3/C2**:CREATE/DROP TABLE override 内先解析 `getRemoteName()`/`getRemoteDbName()` 再发连接器(否则名映射场景删错/建错对象,数据正确性回归)。 + +上述每项修完都应配**端到端 live SQL**:无 ENGINE 的 CREATE TABLE、分区表 SELECT、SHOW PARTITIONS、partitions() TVF、INSERT(看 affected rows)、DROP DATABASE FORCE 非空库。 + +### B. **强烈建议在本批次内修复**(major,影响正确性/可观察输出) + +- **READ-P3/C2**:打通分区裁剪(暴露分区 API + planScan 透传 prunedSpecs),否则大分区表整表扫。 +- **WRITE-P1/C1**:`doBeforeCommit` txn 分支回填 `loadedRows = getUpdateCnt()`(一行,链路已存在)。 +- **READ-P4/C3**:datetime 字面量按 `yyyy-MM-dd HH:mm:ss.SSS` 格式化、源时区改用会话时区。 +- **DROP DATABASE FORCE(DDL-P2/C3)**:**先用真实 ODPS 验证 `schemas().delete` 对非空库的行为**;若拒删则必须补回级联(逐表 drop)或在 force=true+非空库时报明确错。 + +### C. **可接受 / 待定**(须显式登记 deviation,Rule 12) + +- **READ-P5/P6/C4**(limit-opt 无条件触发)、**READ-C6**(CAST 下推)、**READ-C7**(isKey)、**READ-C8**(split locationType)、**WRITE-P2/C2**(block 上限)、**WRITE-P3/C3**(post-commit 吞错,实为改进)、**DDL-C5**(IF NOT EXISTS 冗余 editlog)、**CACHE-P1**(partition_values 死代码 + 每查询多一次 round-trip):若产品决定接受,**逐条写入 deviations-log 并在 release note 声明能力收敛**,不得静默。 +- **REPLAY-P1 / editlog-cache 顺序反转**:无可观察回归,接受,但在设计文档显式声明顺序差异。 +- **READ-C9(IN/NOT IN)**:确认为有意修正 legacy bug,回归用例以正确语义为基线。 + +**一句话决策建议**:当前翻闸**不具备 live 验收条件**——至少 A 类 6 项(2 个读 blocker + CREATE TABLE + partitions/SHOW PARTITIONS 门 + 远端名解析)必须先修;Batch D 的删除动作在 partitions() TVF 真正接线前**应冻结**,以免触发自伤。 + +## 🔴 与历史结论的分歧(最高优先级) + +| 路径 | 历史声称 | 本轮立场 | 证据 | 历史出处 |

Must **atomically replace** (RuntimeTypeAdapterFactory throws duplicate-label IAE if both forms coexist — P2-T03 precedent). +- `PluginDrivenExternalTable` (`fe-core/.../datasource/PluginDrivenExternalTable.java`): `getEngine()` switch `:196-215` (cases jdbc/es/trino-connector), `getEngineTableTypeName()` `:218-231`.

Mirrors P2 trino batch-B. + +1. `GsonUtils`: replace `registerSubtype(MaxComputeExternalCatalog…)` `:397` → `registerCompatibleSubtype(PluginDrivenExternalCatalog.class, "MaxComputeExternalCatalog")` (move into the `:405-412` block); same for table `:472` → `registerCompatibleSubtype(PluginDrivenExternalTable.class, "MaxComputeExternalTable")` (into `:478-483`). Atomic replace. +2. `PluginDrivenExternalTable.getEngine()` `:196-215` + `getEngineTableTypeName()` `:218-231`: add `case "max_compute"`. +3. `legacyLogTypeToCatalogType`: **no change** (default branch covers it — verified §1.1). Add a code comment noting MAX_COMPUTE relies on the default, to prevent a future "add a redundant case" churn. + +Gate: compile + checkstyle + import-gate (fe-core only). Commit `[P4-T05]`. Still dormant — `max_compute` not yet in `SPI_READY_TYPES`, so live catalogs remain legacy. + +> ⚠️ Intermediate-state caveat (P2 batch-B precedent): after the atomic GSON replace but **before** the flip, a freshly-created MC catalog cannot round-trip (compat subtype registered, but factory still legacy). Do not deploy between T05 and T06; land them close together. + +### 3.4 Implementation notes (T05 landed 2026-06-06 — gate-green, pending commit) +- **DB registration folded in (correction to §3.1 / §8 step 1).** The ordered TODO listed only catalog `:397` + table `:472`, but the **database** `:452` (`MaxComputeExternalDatabase`) was still a plain `registerSubtype`. Left un-migrated it throws `ClassCastException` post-flip: `MaxComputeExternalDatabase.buildTableInternal:44` casts `extCatalog` to `MaxComputeExternalCatalog`, but a replayed catalog is now `PluginDrivenExternalCatalog`. es/jdbc/trino migrated catalog+**db**+table together (their legacy DB classes are deleted). T05 therefore migrated **all three** GSON registrations to `registerCompatibleSubtype` + removed the 3 now-unused `maxcompute.*` imports. Verified safe: `InitDatabaseLog.Type.MAX_COMPUTE` has no replay-dispatch use (self-ref only); `dbLogType` is not `@SerializedName` → handled identically to the shipped es/jdbc/trino DBs. +- **Adversarial verification fan-out (4 read-only agents) — 2 alarms adjudicated as non-issues:** + - *`getMetaCacheEngine()` → "default" not "maxcompute"* = **false positive.** The plugin path loads schema via the connector (`PluginDrivenExternalTable.initSchema`) under the "default" bucket — exactly as shipped es/jdbc/trino tables (which never overrode it). `MaxComputeExternalMetaCache` is referenced only by legacy `MaxComputeExternalTable:71,122` (Batch-D dead code); partitions come from the connector (P4-T02). No override needed. + - *`getMysqlType()` → "BASE TABLE" not null* = **consistent with accepted precedent.** Migrated ES tables already went null→"BASE TABLE" (`ES_EXTERNAL_TABLE` is absent from `TableType.toMysqlType`) and shipped with no override. MC matching is the same accepted change. + - *dormancy ("a new MC catalog can't serialize in the T05↔flip window")* = the **already-documented** intermediate-state caveat above. The agent's suggested fix (keep `registerSubtype` too) is **wrong** — coexistence throws the duplicate-label IAE the atomic replace exists to avoid. No action. +- **Test:** `PluginDrivenExternalTableEngineTest` extended with 2 `max_compute` cases (engine = null; type name = `MAX_COMPUTE_EXTERNAL_TABLE`) — 9/9 green. Matches the file's existing Mockito helper (the §7 "no mockito" guidance is for new T06 files). +- **Gate (fe-core):** compile BUILD SUCCESS · checkstyle 0 · import-gate 0 · UT 9-0-0 (real BUILD/MVN_EXIT/CS_EXIT verified). + +--- + +## 4. P4-T06 — live cutover + +### 4.1 Dormant→live write wiring (the hard part — all dormant-safe, additive) + +**W-a (G1) — bind a txn into the session.** `ConnectorSession`: add `default void setCurrentTransaction(ConnectorTransaction txn) { throw … }` (or no-op default + override). `ConnectorSessionImpl`: add a `volatile ConnectorTransaction currentTransaction` field + `setCurrentTransaction` + `@Override getCurrentTransaction()`. `PluginDrivenTableSink`: add `getConnectorSession()` getter (field exists `:114`, no getter today). + +**W-b (DECISION-1) — capability signal.** Add `ConnectorWriteOps.usesConnectorTransaction()` default `false`; `MaxComputeConnectorMetadata` overrides `true`. The executor routes on this **before** touching any throwing-default write method. (Alternatives weighed in §5.) + +**W-c (G2) — `PluginDrivenInsertExecutor` restructure** (mirrors legacy `MCInsertExecutor`, which returns `TransactionType.MAXCOMPUTE` `:81-82` and pulls the txn from the manager): +- Extract connector/session/writeOps setup into a helper; call it at the **start of `beginTransaction()`** (currently built in `beforeExec:71-76`). +- `beginTransaction()`: + - txn-model: `connectorTx = writeOps.beginTransaction(execSession)` (`MaxComputeConnectorMetadata:264` → `new MaxComputeConnectorTransaction(session.allocateTransactionId())`); `txnId = ((PluginDrivenTransactionManager) transactionManager).begin(connectorTx)`. + - else: `super.beginTransaction()` (unchanged `:87-89`). +- `finalizeSink()` (override): if `connectorTx != null && sink instanceof PluginDrivenTableSink`, `((PluginDrivenTableSink) sink).getConnectorSession().setCurrentTransaction(connectorTx)` **before** `super.finalizeSink(...)`. +- `beforeExec()` (override): `if (connectorTx != null) return;` (write session already created by `planWrite`; no `getWriteConfig`/`beginInsert`). JDBC path unchanged. `doBeforeCommit`/`onFail` already guard on `insertHandle != null` (`:108`,`:140`) → null for MC ⇒ correctly skipped. +- `transactionType()`: txn-model → `TransactionType.MAXCOMPUTE` (enum value exists; profiling-only, low-risk — note it's MC-specific in a generic executor, acceptable while MC is the sole txn-model adopter). + +Two `ConnectorSession` instances exist (executor's, built for id-alloc; sink's, which planWrite reads) — the **txn is shared by reference** via W-a, so this is correct; a future simplification could unify them, out of scope here. + +**W-d (G3) — global registration.** `PluginDrivenTransactionManager.begin(connectorTx)` `:71-77`: also `Env.getCurrentEnv().getGlobalExternalTransactionInfoMgr().putTxnById(txnId, theWrappedTxn)` (mirror `AbstractExternalTransactionManager.begin:42-48`). Verify `commit`/`rollback` (`:80-…`) `removeTxnById` (add if missing — legacy removes at `AbstractExternalTransactionManager:54`).

Keep it the **last** commit (§4.5). + +### 4.4 R-004 — ODPS-SDK-under-plugin-classloader defensive test +Risk (risks.md R-004): "classloader 隔离打破 SDK 单例." Plugin isolation = `ConnectorPluginManager` + `ChildFirstClassLoader`, parent-first prefixes `org.apache.doris.connector.*` / `org.apache.doris.filesystem.*`. No in-repo harness loads a plugin **under its isolated classloader** (`FakeConnectorPluginTest` loads via the test classpath — does NOT exercise isolation). No ODPS endpoint/creds in the repo. + +**Two separable concerns** — split the test accordingly: +1. **Isolation correctness (no creds, CI-runnable):** load the connector under a plugin-style classloader and instantiate the ODPS client (`MCConnectorClientFactory`, needs `mc.endpoint`/`mc.default.project`/auth) — assert **no `NoClassDefFoundError` / `ClassCastException` / SDK-singleton poisoning** when class-loading the ODPS SDK in isolation. This is the part that actually addresses R-004's "broken singleton" risk and can run without a live endpoint. +2. **Live connectivity (creds, user-run):** one trivial metadata call (e.g. `odps.projects().get(project).reload()` or `tables().exists`) against a real endpoint. **I author it; user runs it** (per sign-off; mirrors P0-T24/25). Credentials via env vars / system properties — never committed. + +Cutover is declared complete only after the user reports (2) green; (1) lands as a normal connector UT. + +### 4.5 Commit granularity +All of §4.1+§4.2 is **additive / dormant-safe** (only reachable once `max_compute` is in `SPI_READY_TYPES`). Recommended ordering inside T06: land write-wiring + binding-context + R-004-isolation-UT **first** (dormant), then the **flip** (§4.3) as the final, smallest, highest-signal commit. (DECISION-2: is this two commits `[P4-T06a]`/`[P4-T06b]`, or one `[P4-T06]`?) + +--- + +## 5. Decisions (✅ all signed off 2026-06-06) + +**DECISION-1 ✅ = (A)** `ConnectorWriteOps.usesConnectorTransaction()` flag. — capability signal for the txn-write model (W-b): +- **(A) `ConnectorWriteOps.usesConnectorTransaction()` flag, default false — CHOSEN.** Matches the SPI's existing capability style (`supportsInsert/Delete/Merge`, `supportsWriteBlockAllocation`); explicit; one default method; zero coupling; lets the executor branch *before* any throwing-default call. +- (B) Route on `connector.getWritePlanProvider() != null`. Zero new SPI, but couples "has a write-plan provider" with "uses a connector transaction" — loose; breaks for a future planWrite-but-autocommit connector. +- (C) Un-throw `getWriteConfig` for MC + add `ConnectorWriteType.MAXCOMPUTE` (or reuse `CUSTOM`); route on write-type. Reuses one SPI method conceptually, but reverses D-4, adds enum churn, and forces `getWriteConfig` to be called earlier. More moving parts (Rule 2 disfavors). + +**DECISION-2 ✅ = two commits, flip last** (§4.5): `[P4-T06a]` = wiring/binding/R-004 isolation UT (dormant); `[P4-T06b]` = the SPI_READY_TYPES flip + delete CatalogFactory case.

The helper must map between them. +- **Must NOT** reuse `TableType.MAX_COMPUTE_EXTERNAL_TABLE.toEngineName()`: that enum has no case in + `TableIf.toEngineName()` → returns `null` (confirmed; `PluginDrivenExternalTable.getEngine()` + itself documents this null). Mapping must be a direct literal `"max_compute" → ENGINE_MAXCOMPUTE`. +- Downstream is satisfied once padded: `checkEngineName` (`:940-944`) and `analyzeEngine` + (`:1121-1127`) whitelist `ENGINE_MAXCOMPUTE`, so producing `"maxcompute"` makes the rest of the + path byte-identical to legacy with zero further edits. + +## Design +Mirror the in-repo convention `PluginDrivenExternalTable.getEngine()` (switch on +`((PluginDrivenExternalCatalog) catalog).getType()`): add a `PluginDrivenExternalCatalog` branch to +both gate methods, keyed on `getType()` (not a hardcoded `instanceof MaxComputeExternalCatalog`), so +it generalizes to any future full-adopter and survives Batch-D deleting the legacy MC branch. + +1. **Import** — add `import org.apache.doris.datasource.PluginDrivenExternalCatalog;`. **Placement + (critic correction):** immediately after `:49 org.apache.doris.datasource.InternalCatalog` and + **before** `:50 org.apache.doris.datasource.hive.HMSExternalCatalog`. Rationale: Checkstyle + `CustomImportOrder` is ASCII-case-sensitive; after `org.apache.doris.datasource.` the next char is + uppercase `P` (0x50) for PluginDriven vs lowercase `h`/`i`/`m`/`p` (≥0x68) for the + `hive.`/`iceberg.`/`maxcompute.`/`paimon.` sub-packages, so `P` sorts **before** all of them and + **after** `I` (InternalCatalog, 0x49). Grouped with the top-level `datasource.*` classes + (`CatalogIf :48`, `InternalCatalog :49`), NOT after the sub-packages. (The parent design's + "between :51/:52, after MaxCompute" was off-by-two and would put it after `hive`/`iceberg` → + Checkstyle reject.) + +2. **`paddingEngineName`** — insert after the MC branch (`:913`), before the `:914 else`: + ```java + } else if (catalog instanceof PluginDrivenExternalCatalog + && pluginCatalogTypeToEngine((PluginDrivenExternalCatalog) catalog) != null) { + engineName = pluginCatalogTypeToEngine((PluginDrivenExternalCatalog) catalog); + } else { + throw new AnalysisException("Current catalog does not support create table: " + ctlName); + } + ``` + A max_compute PluginDriven catalog gets `engineName = "maxcompute"`. A jdbc/es/trino PluginDriven + catalog (helper returns `null`) falls through to the existing `else` and throws the **same** + "does not support create table" message it already throws today — byte-identical pre/post for + those types. + +3. **`pluginCatalogTypeToEngine` (new `private static`) — RETURNS `null` for unmapped types, does + NOT throw** (refinement over parent design — Rule 7): + ```java + // Maps a PluginDriven (SPI) catalog's type to the legacy engine name used for DDL + // engine-padding / catalog-engine consistency. Keyed on getType() (CatalogFactory key), + // mirroring PluginDrivenExternalTable.getEngine()/getEngineTableTypeName(); the two switches + // must stay in sync if SPI_READY_TYPES gains a CREATE-TABLE-capable full-adopter. + // Returns null for SPI types that do not support CREATE TABLE (jdbc/es/trino-connector), + // so callers preserve their existing behavior for those types. + private static String pluginCatalogTypeToEngine(PluginDrivenExternalCatalog catalog) { + switch (catalog.getType()) { + case "max_compute": + return ENGINE_MAXCOMPUTE; + default: + return null; + } + } + ``` + **Why null, not default-throw (the parent design's version):** the helper is shared by BOTH gate + methods. If it threw for non-max_compute types, then `checkEngineWithCatalog` — which legacy lets + jdbc/es/trino pass through unconditionally (they are not in legacy's instanceof chain) — would + newly throw for a jdbc catalog with an explicit engine. Returning null lets each caller keep + legacy semantics: `paddingEngineName` falls to its existing else-throw; `checkEngineWithCatalog` + simply skips. This makes jdbc/es/trino byte-identical to legacy in **both** methods; only + max_compute gains behavior. + +4. **`checkEngineWithCatalog`** — insert after the MC branch (`:391`), before the `:392` close: + ```java + } else if (catalog instanceof PluginDrivenExternalCatalog) { + String pluginEngine = pluginCatalogTypeToEngine((PluginDrivenExternalCatalog) catalog); + if (pluginEngine != null && !engineName.equals(pluginEngine)) { + throw new AnalysisException("MaxCompute type catalog can only use `maxcompute` engine."); + } + } + ``` + `pluginEngine` is non-null only for max_compute, so the message is only ever reachable for + max_compute and is the **verbatim legacy MC message** (`:391`) — matching the established + convention asserted for sibling catalogs (`test_iceberg_create_table.groovy` / `test_hive_ddl.groovy`: + `" type catalog can only use \`\` engine."`). jdbc/es/trino (pluginEngine == null) + fall through with no throw, exactly as legacy. + +5. **SPI / connector / thrift / BE: no change.** The `Connector` SPI has no engine-name concept; + adding one is over-design. `getType()` is sufficient. Pure fe-core. + +## Implementation Plan (fe-core only) +1. `CreateTableInfo.java`: add the import (§Design 1, exact placement). +2. `CreateTableInfo.java:896-918 paddingEngineName`: insert the PluginDriven branch (§Design 2). +3. `CreateTableInfo.java:376-393 checkEngineWithCatalog`: insert the PluginDriven branch (§Design 4). +4. `CreateTableInfo.java`: add `private static pluginCatalogTypeToEngine` (§Design 3). +5. Gate: `mvn -pl :fe-core -am` (compile + UT); `fe-code-style` Checkstyle (new import must be used + + correctly ordered). Independent commit `[P4-T06d] FIX-DDL-ENGINE`. + +## Risk +- **Regression surface is narrow**: a new branch fires only when (padding) `engineName` is empty AND + catalog is PluginDriven, or (check) catalog is PluginDriven. HMS/Iceberg/Paimon/Internal and + legacy-MC (`instanceof MaxComputeExternalCatalog`, still in keep-set) paths are byte-unchanged + (branch order: after MC, before else / before close). +- **jdbc/es/trino**: byte-identical to legacy in both methods (null-returning helper, §Design 3). + No new capability, no new breakage. Verified non-regressive: pre-fix they already hit the same + `:915` "does not support create table" throw; `ConnectorTableOps.createTable` default also throws. +- **CTAS**: fixed transitively (validateCreateTableAsSelect → paddingEngineName); covered by UT. +- **Follower replay / master sync**: not a concern — engine padding is analysis-time on the receiving + FE; persistence uses `logCreateTable` independent of engineName. +- **getType() string fragility**: depends on the `"max_compute"` literal (CatalogFactory key), same + convention as `PluginDrivenExternalTable.getEngine()`. The helper comment cross-references both so a + future SPI_READY_TYPES key change updates both switches. +- **Checkstyle/import-gate**: one new import, used in 3 places; placement verified (§Design 1). + +## Batch-D ordering (keep-set dependency — must record in decisions-log) +`P4-batchD-maxcompute-removal-design.md:100` plans to delete both +`instanceof MaxComputeExternalCatalog` branches in `CreateTableInfo`. This fix **must land first**; +Batch-D then degrades to "delete only the legacy MC instanceof branches + the +`maxcompute.MaxComputeExternalCatalog` import", leaving the PluginDriven branches (keyed on +getType()) in place. If Batch-D runs first, no-ENGINE CREATE TABLE is permanently broken (the +"amendment self-triggers" pattern). This fix depends on the `MaxComputeExternalCatalog` import +staying in keep-set until Batch-D. (Confirmed `UnboundTableSinkCreator` already has PluginDriven +branches from T06c, so `CreateTableInfo` is the last unwired analysis-time CREATE TABLE gate.) + +## Test Plan +**UT (CI-runnable, fe-core)** — new file +`fe/fe-core/src/test/java/org/apache/doris/nereids/trees/plans/commands/info/CreateTableInfoEngineCatalogTest.java` +(same package → can construct `CreateTableInfo`; private gate methods invoked via reflection). +Infra (mirrors `PluginDrivenExternalCatalogDdlRoutingTest`): `MockedStatic` → +`mockEnv.getCatalogMgr()` → `mockCatalogMgr.getCatalog("mc_ctl")` returns a +`Mockito.mock(PluginDrivenExternalCatalog.class)` with `getType()` stubbed to `"max_compute"` (a +Mockito mock IS an `instanceof PluginDrivenExternalCatalog`; getType() is non-final). **This +registration via the mocked CatalogMgr is mandatory** because both gate methods look the catalog up +by name (critic correction — a directly-constructed catalog would be ignored). + +Cases (each assertion message encodes WHY — Rule 9; each fails if its branch is reverted): +1. `noEnginePaddedToMaxcomputeForPluginDriven` — `CreateTableInfo` with empty engine, ctl `"mc_ctl"`; + reflectively invoke `paddingEngineName("mc_ctl", null)`; assert `getEngineName() == "maxcompute"`. + WHY: no-ENGINE CREATE TABLE must auto-pad maxcompute, not throw. (Revert branch → throws "does not + support create table" → red.) +2. `ctasNoEnginePaddedToMaxcompute` — drive the **CTAS** entry point + `validateCreateTableAsSelect(["mc_ctl"], , ctx)` far enough to assert padding ran (assert + `getEngineName() == "maxcompute"` after the call, or that it does not throw "does not support + create table").

Legacy worked; cutover breaks it. Severity: **blocker**. + +## Root Cause + +Direct cause: `MaxComputeConnectorMetadata` lacks a `buildTableDescriptor` override (unlike +`JdbcConnectorMetadata.java:182-217` / `EsConnectorMetadata.java:121-131`). The dispatch + +SPI hook + null fallback in fe-core are correct and generic; the fix belongs in the MC connector. + +## Design (decisions B1–B4) + +- **B1** — Add `@Override public org.apache.doris.thrift.TTableDescriptor buildTableDescriptor(...)` + to `MaxComputeConnectorMetadata` with the SAME signature as the SPI default. Build a `TMCTable` + and call `setEndpoint(endpoint)`, `setQuota(quota)`, `setProject(dbName)`, `setTable(remoteName)`, + `setProperties(properties)`. `project`/`table` use the **remote-name params** (`dbName`, + `remoteName` are already remote at the call site — see B-registrations OQ-7). Do **not** set + region/access_key/secret_key/public_access/odps_url/tunnel_url (legacy leaves them unset / + deprecated — mirror that; credentials flow through the `properties` map). +- **B2** — Construct + `new org.apache.doris.thrift.TTableDescriptor(tableId, TTableType.MAX_COMPUTE_TABLE, numCols, 0, tableName, dbName)` + then `setMcTable(tMcTable)`. The **6th ctor arg (descriptor dbName field) = remote `dbName` param**, + mirroring legacy `MaxComputeExternalTable.toThrift:318-319` which passes `dbName` there. BE does + NOT read this field for MC reads (JNI scanner uses `TMCTable.project/table`), so it is harmless, + but we mirror legacy faithfully (this diverges from jdbc/es which pass `""` — recorded below). +- **B3** — Extend `MaxComputeConnectorMetadata` ctor with + `private final String endpoint; private final String quota; private final Map properties;` + (reuse existing `java.util.Map` import) + corresponding ctor params; assign them. Update + `MaxComputeDorisConnector.getMetadata` to pass `endpoint, quota, properties`. These fields are + assigned in `doInit()` and `getMetadata()` calls `ensureInitialized()` first, so they are non-null + at construction time. +- **B4** — Style: match the jdbc/es override exactly — fully-qualified `org.apache.doris.thrift.*` + names, **no new thrift imports**. The connector import-gate only forbids fe-core internal packages + and only scans `^import` lines in `src/main/java`; fully-qualified usage trips neither it nor + Checkstyle. The only reused import is `java.util.Map` (already present). + +## Implementation Plan (per file) + +1. `fe/fe-connector/fe-connector-maxcompute/.../MaxComputeConnectorMetadata.java` + - Add three final fields `endpoint`, `quota`, `properties` and extend the ctor with the three + params; assign them. + - Add `@Override buildTableDescriptor(...)` per B1/B2 (fully-qualified thrift names). +2. `fe/fe-connector/fe-connector-maxcompute/.../MaxComputeDorisConnector.java` + - `getMetadata`: `new MaxComputeConnectorMetadata(odps, structureHelper, defaultProject, endpoint, quota, properties)`. +3. No changes to BE, thrift, fe-core, or any other connector. + +Gate: only the connector is touched → `mvn ... -pl :fe-connector-maxcompute` (no `-pl :fe-core`). + +## Risk + +- Low: pure new override + ctor passthrough. No fe-core dispatch / BE / thrift / other-connector + change. jdbc/es/trino unaffected (own override or null fallback). +- Keep-set untouched: legacy `MaxComputeExternalTable.toThrift` stays (unused under cutover; removed + in Batch D). No ordering conflict with this fix. +- BE `descriptors.cpp:289-320` reads region/access_key/... without `__isset` guards, but since we set + the whole `mcTable`, unset fields default to empty strings (not UB) — identical to legacy, which also + does not set them. + +## Test Plan + +- **UT** — new `MaxComputeBuildTableDescriptorTest` in + `fe/fe-connector/fe-connector-maxcompute/src/test/java/org/apache/doris/connector/maxcompute/`. + Plain JUnit 5 (no fe-core dep, no Mockito). Construct `MaxComputeConnectorMetadata` directly with + `null` odps/structureHelper (ctor only assigns; `buildTableDescriptor` never dereferences them) and + real endpoint/quota/properties/defaultProject. Call `buildTableDescriptor(null, tableId, tableName, + dbName, remoteName, numCols, catalogId)` and assert: (1) result != null; (2) + `getTableType()==MAX_COMPUTE_TABLE`; (3) `isSetMcTable()`; (4) `mcTable.getEndpoint()/getQuota()/ + getProject()==dbName/getTable()==remoteName/getProperties()` equal inputs. Comment encodes WHY: BE + static_casts to `MaxComputeTableDescriptor` and reads these as the auth/addressing contract — a + SCHEMA_TABLE/null fallback crashes BE (Rule 9). The test FAILS if the override returns null or a + SCHEMA_TABLE descriptor. +- **E2E (user-run, live ODPS)** — under cutover, run `test_external_catalog_maxcompute.groovy` / + `test_max_compute_all_type.groovy` `SELECT` with column projection (a real-data SELECT, not just + `count(*)`, per critic gap) against existing `.out` baselines. +- **Build note (both modules).** Run these UTs with `-am` (e.g. + `mvn -f fe/pom.xml -pl :fe-core -am -DfailIfNoTests=false -Dtest=PluginDrivenExternalTableEngineTest test`). + Without `-am`, sibling SNAPSHOT artifacts (incl. the connector-api jar) resolve from a stale + `~/.m2`, causing `NoClassDefFoundError: ConnectorTransaction`. The `-am` reactor build also requires + `-DfailIfNoTests=false` so the `-Dtest=` filter does not fail upstream modules with "No tests were + executed". + +## Parity & boundary registrations + +- **OQ-7 — project/table use remote names (intentional fix).** The SPI read session itself uses + remote names: `PluginDrivenScanNode` builds the table handle from `db.getRemoteName()/table + .getRemoteName()`, and the JNI scanner does `requireNonNull(project)` + `odps.setDefaultProject( + project)`. So the descriptor MUST carry remote names to stay consistent with the read session; + reverting to legacy local names would diverge from the SPI read session. This is the correct, + not merely tolerable, choice (same family as DDL-P3/DDL-C2 remote-name fixes). Note: for the + actual data read the descriptor `project/table` are largely vestigial — real addressing uses the + FE-prebuilt serialized scan session — but they must still be the remote names for consistency and + to satisfy the BE `MaxComputeTableDescriptor` contract. +- **6th ctor arg dbName choice.** We pass the **remote `dbName` param** (mirrors legacy + `MaxComputeExternalTable.toThrift:318-319`), NOT `""` as jdbc/es do. BE does not read + `TTableDescriptor.dbName` for MC reads, so it is harmless; we choose legacy-faithful over + jdbc/es-uniform here, and record the deliberate divergence from the jdbc/es style. +- **UT coverage boundary (now closed — two-sided).** Coverage is split across two modules: + 1. The connector UT (`MaxComputeBuildTableDescriptorTest`) asserts the override's OWN output. It + CANNOT reach the fe-core `PluginDrivenExternalTable.toThrift` call site (cross-module; this + module has no fe-core dependency). + 2. The fe-core call site is now covered by + `PluginDrivenExternalTableEngineTest#testToThriftPassesRemoteNamesAndNumColsToBuildTableDescriptor` + (`fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalTableEngineTest.java`). + It uses a Mockito-mocked `ConnectorMetadata` with an `ArgumentCaptor` on `buildTableDescriptor`, + drives `table.toThrift()` (stubbing only the two Env-backed methods it traverses — + `makeSureInitialized()` and `getFullSchema()` — plus a `TestablePluginCatalog.getConnector()` + override that bypasses Env-backed catalog init), and asserts the captured args: + `dbName == "REMOTE_DB"` (≠ local `mydb`), `remoteName == "REMOTE_TBL"` (≠ local `mytbl`), and + `numCols == schema.size()`. Local names differ from remote names so a regression that passes + local names (or a wrong numCols) FAILS the test (verified by a temporary mutation: + `db.getRemoteName()→db.getFullName()` / `getRemoteName()→getName()` / `size()→size()+1` + produced `expected: but was: `). The previous "e2e-only" claim is superseded: + the call-site wiring is now automated; e2e still covers the live-ODPS end-to-end read. +- **time_zone note.** The BE JNI scanner requires `time_zone`, but BE injects it via the jni_reader + framework (`jni_reader.cpp:151` `_scanner_params.emplace("time_zone", _state->timezone())`) for all + JNI scanners, NOT via the descriptor. So this fix neither needs nor touches `time_zone`.

Concretely: +- (a) **Consistent-hash split→BE placement** will differ from the **current buggy build** (because + the hashed `getLength()` changes from 268435456 to -1). This is invisible/benign for correctness + and matches legacy. Do NOT mistake this A/B placement difference for a regression during + validation. +- (b) **`totalFileSize` goes negative** for byte_size scans (one `-1` per split).

Two tests: +- `byteSizeBranchEmitsMinusOneSizeSentinel` — asserts size == -1 (plus startOffset == splitIndex and + path == `"[ 7 , -1 ]"`). **This guards the provider's CHOICE, not just the range mechanism**: + reverting the byte_size branch to `.length(splitByteSize)` makes it FAIL with + `expected: <-1> but was: <268435456>` (verified by a real revert — see below). +- `rowOffsetBranchKeepsRealRowCount` — contrast: the row_offset branch carries the real row count + (never the -1 sentinel), locking the intent that ONLY byte_size uses -1 (guards against an + over-broad "set everything to -1" fix). + +Each assertion message encodes WHY (Rule 9): BE distinguishes BYTE_SIZE vs ROW_OFFSET solely by +`size == -1`; a wrong value → silent corrupt read. + +**Why provider-level (not the weak range-level UT):** the parent design proposed a UT that builds a +range with `.length(-1)` itself then asserts `getSize()==-1`. That is weak — it sets length=-1 +itself, so it would NOT fail if the provider reverted to `.length(splitByteSize)`; it locks the +range mechanism, not the fix. This UT instead exercises the changed provider line, so it is a real +regression red point. + +**E2E (NOT run in normal CI):** `regression-test/suites/external_table_p2/maxcompute/ +test_external_catalog_maxcompute.groovy` is an `external_table_p2` suite requiring **live +MaxCompute/ODPS credentials**, so it is **SKIPPED in normal CI**.

No overrider in any connector needs updating. +- **No existing test assertions break.** `PluginDrivenExternalTablePartitionTest:171-207` uses the + 5-arg ctor and asserts on partition pruning, not on auto-inc — unaffected. + `CreateTableInfoToConnectorRequestConverterTest` asserts name/nullable/comment/partition/bucket, + none of which change for its fixtures (all use non-auto-inc `ColumnDefinition`s, so + `isAutoInc==false`) — unaffected. +- **fe-connector-api consumers rebuilt:** since the SPI module (`fe-connector-api`) changes, the + build must rebuild api + maxcompute + fe-core (operational note). No es/jdbc/hive/hudi/iceberg/ + paimon/trino source edits. +- **Import-gate:** no connector module gains an fe-core import (the new field lives in + fe-connector-api; the converter that reads `getAutoIncInitValue()` is already in fe-core). The + maxcompute change uses only already-imported symbols. `bash tools/check-connector-imports.sh` + stays green. + +## Risk Analysis + +- **Risk: a legitimate non-auto-inc CREATE TABLE wrongly rejected.** Mitigated: the gate is + `getAutoIncInitValue() != -1`, the exact same predicate `toSql` (`:225`) uses to emit + `AUTO_INCREMENT`; default is `-1`. The converter test asserts a normal column yields + `isAutoInc()==false`. +- **Risk: behavior drift for the other 6 connectors.** Eliminated by additive default `false` — + proven above; their producers never set auto-inc, and their `validateColumns` (if any) do not + read it. +- **Risk: package-private `validateColumns` widens API surface.** Minimal: it stays package-private + (not public), is documented as test-only, and the method is pure FE-side validation. Matches the + module's existing offline-test idiom. +- **Risk: equals/hashCode change breaks a set/map keyed on ConnectorColumn.** Low: adding a field + to equals/hashCode is the correct invariant (two columns differing only in auto-inc ARE + different). No production code keys collections on `ConnectorColumn` identity across the auto-inc + boundary (all producers default false, so existing keys are unchanged in value). +- **Risk: aggregation half (F31) erroneously added.** Explicitly excluded per issue and report; + only the auto-inc branch is mirrored. +- **Truth-gate:** UT is sufficient here — the rejection is pure FE validation that throws before + any ODPS RPC, so no live ODPS e2e is required (unlike the write-path blockers). + +## Test Plan + +### Unit Tests + +#### A. Connector validation — `fe-connector-maxcompute` + +- **File:** `fe/fe-connector/fe-connector-maxcompute/src/test/java/org/apache/doris/connector/maxcompute/MaxComputeValidateColumnsTest.java` (new) +- **Class:** `MaxComputeValidateColumnsTest` +- **Setup:** construct `new MaxComputeConnectorMetadata(null, null, "proj", "ep", "quota", emptyMap)` + (same offline idiom as `MaxComputeBuildTableDescriptorTest`); call the now package-private + `validateColumns(List)` directly. +- **Tests:** + - `autoIncColumnIsRejected` — list = `[new ConnectorColumn("id", ConnectorType.of("INT"), "", + false, null, false, true)]` → assert `DorisConnectorException` thrown AND message contains + `"Auto-increment columns are not supported for MaxCompute tables: id"`. + **WHY (Rule 9):** MaxCompute physically cannot store auto-increment; legacy rejected it loudly + (`MaxComputeMetadataOps:422-425`). Silent acceptance is a data-model regression — the user's + auto-inc intent is dropped without warning. This test fails if the connector ever stops + rejecting auto-inc. + - `nonAutoIncColumnPasses` — list = `[new ConnectorColumn("id", ConnectorType.of("INT"), "", + false, null, false, false)]` → assert `validateColumns` returns without throwing. + **WHY:** guards against over-rejection — a normal column must still create successfully; the + gate must key on the flag, not reject all columns. +- **MUTATION:** removing the `if (col.isAutoInc()) throw ...` block in + `MaxComputeConnectorMetadata.validateColumns` makes `autoIncColumnIsRejected` go red (no + exception). This is the one-line production revert that re-introduces the regression. + +#### B. Converter passthrough — `fe-core` + +- **File:** `fe/fe-core/src/test/java/org/apache/doris/connector/ddl/CreateTableInfoToConnectorRequestConverterTest.java` (existing — add tests) +- **Class:** `CreateTableInfoToConnectorRequestConverterTest` +- **Tests:** + - `autoIncInitValueIsPropagatedAsIsAutoInc` — build a `ColumnDefinition` with + `autoIncInitValue != -1` using the public 10-arg ctor + (`new ColumnDefinition("id", IntegerType.INSTANCE, false, null, ColumnNullableType.NOT_NULLABLE, + 1L /*autoIncInitValue*/, Optional.empty(), Optional.empty(), "", Optional.empty())`), run + `convert(...)`, assert `req.getColumns().get(0).isAutoInc() == true`. + **WHY (Rule 9):** the connector can only reject what the converter carries. This proves the + flag survives the `ColumnDefinition → ConnectorColumn` boundary, i.e. the converter does not + re-drop it. Without passthrough, the connector gate (Test A) is dead code. + - `plainColumnIsNotAutoInc` — existing-style `ColumnDefinition` (default `autoIncInitValue == -1`) + → assert `isAutoInc() == false`. + **WHY:** guards the `!= -1` predicate boundary — a normal column must map to false, not true + (catches an inverted/constant-true mistake). +- **MUTATION:** reverting the converter to the 6-arg ctor (dropping the 7th arg, i.e. not passing + `d.getAutoIncInitValue() != -1`) makes `autoIncInitValueIsPropagatedAsIsAutoInc` go red + (`isAutoInc()` would be false). + +#### C. SPI equals/hashCode — `fe-connector-api` + +- **File:** `fe/fe-connector/fe-connector-api/src/test/java/org/apache/doris/connector/api/ConnectorColumnTest.java` (new) +- **Class:** `ConnectorColumnTest` +- **Tests:** + - `equalsAndHashCodeDistinguishAutoInc` — two columns identical except + `isAutoInc` (`...false, false` vs `...false, true`) → assert `!a.equals(b)` and (best-effort) + `a.hashCode() != b.hashCode()`. + **WHY (Rule 9):** auto-inc is now a semantic discriminator; two columns differing only by it are + genuinely different. If equals/hashCode ignored the field, collections deduping + `ConnectorColumn`s could collapse an auto-inc column onto a plain one, silently re-dropping the + flag downstream. + - `defaultCtorsLeaveAutoIncFalse` — `new ConnectorColumn("c", ConnectorType.of("INT"), "", true, + null)` (5-arg) and the 6-arg form both report `isAutoInc() == false`. + **WHY:** locks the additive-default contract — proves the 7 other connectors and read-path + producers (which use 5/6-arg) keep `isAutoInc=false`, i.e. zero behavior change. +- **MUTATION:** removing `&& isAutoInc == that.isAutoInc` from `equals` makes + `equalsAndHashCodeDistinguishAutoInc` go red. + +### E2E Tests + +- No live ODPS e2e required for this fix: the rejection is pure FE-side validation that throws + before any ODPS RPC. CI is UT-only anyway and skips live ODPS. +- Optional regression-test coverage (CI-skip, for the standing live truth-gate documentation): + `regression-test/suites/external_table_p2/maxcompute/test_mc_create_table.groovy` (or the + existing MC DDL suite if present) could add a case asserting + `CREATE TABLE ...

The cutover connector already +raises on this case (`MaxComputeConnectorMetadata.java:343`, +`"Table '...' already exists in database '...'"`), which the override wraps to `DdlException` +at `:282-283`. To keep the change **minimal and surgical** and avoid a second source of truth +for "already exists", we do **not** add an FE-side `ErrorReport.reportDdlException` for the +existing-table check. Instead: +- We only short-circuit (skip the connector call) for the `IF NOT EXISTS` hit. +- For `exists && !isIfNotExists()` we let control fall through to the existing + `connector.createTable(...)` call, which throws → `DdlException` (today's behavior, unchanged). + +This means the FE-side existence probe is used **only** to decide the `IF NOT EXISTS` +short-circuit; the not-`IF NOT EXISTS` error stays exactly as it is today. Trade-off surfaced: +the legacy error code (`ERR_TABLE_EXISTS_ERROR`, MySQL 1050) differs from the connector's +generic `DdlException` message. That message divergence already exists on the cutover branch +today and is **out of scope** for this data-change fix; restoring the exact error code would +add FE-side error machinery for no behavioral parity benefit beyond the message text. Flagged +for cleanup, not fixed here. (If the orchestrator wants exact-message parity, see Open +Question.) + +Also update the stale Javadoc at `:256-261` that claims the override "conservatively assumes +creation happened and writes the edit log" — that statement is now false for the IF-NOT-EXISTS +existing-table path. + +# Implementation Plan + +All production changes in **one** file.

No connector is broken. + +**Callers of the changed method:** +- `Env.createTable` (`Env.java:3749-3752`) → `catalogIf.createTable(info)`: now receives `true` + on the IF-NOT-EXISTS existing-table case.

No code change at the call site; behavior is the fix. +- Plain (non-CTAS) `CREATE TABLE IF NOT EXISTS` on an existing table: `CreateTableCommand.run` + non-CTAS branch (`:91`) calls `Env.createTable` and ignores the return — behavior is now + "no editlog, no SDK call" instead of "redundant editlog"; strictly an improvement, no visible + user effect. + +**Existing tests whose assertions must change: NONE (they are preserved, not changed).** +- `testCreateTablePassesRemoteDbNameToConverter` (`:315-341`): stubs neither `getTableNullable` + nor `getTableHandle`.

Legacy `createTableImpl` did the same `tableExist` + probe (`:179`), so this is **parity, not a new cost** (legacy's `tableExist` was a remote + call too). The `getOdpsTable` inside `getTableHandle` is marginally heavier than a bare + existence check, but CREATE TABLE is rare and not latency-sensitive; acceptable. (Avoiding it + would require a `tableExists` SPI method — rejected per the No-SPI-change directive.) +- **Short-circuit skips the connector's own `IF NOT EXISTS` no-op.** We now never call + `connector.createTable` on the existing+ifNotExists path. The connector's branch + (`:337-341`) was *also* a pure no-op in that case, so no behavior is lost; we just decide it + FE-side (required to get the correct `return true`). +- **Local-vs-remote existence divergence.** If the FE cache is stale (table exists remotely but + not in cache), `getTableHandle` still catches it (remote probe). If it exists in cache but not + remotely (dropped out-of-band), `getTableNullable` catches it → we `return true` and skip + create. Legacy did the identical OR (`:179` remote OR `:189` local), so this is exact parity. +- **Error-message divergence on `exists && !IF NOT EXISTS`** (DdlException text vs legacy + `ERR_TABLE_EXISTS_ERROR`) — pre-existing on the cutover branch, explicitly out of scope, + flagged for cleanup.

Optionally add one explicit +line to that test: `assertFalse(catalog.createTable(info))` capture — but since it already +locks the side effects, adding a 4th near-identical test is redundant. + +**MUTATION CHECK (Rule 9):** +- One-line production revert: change the new branch back to the original unconditional tail — + i.e. delete the `if (exists && createTableInfo.isIfNotExists()) { return true; }` block (so the + method always falls through to `logCreateTable` + `resetMetaCacheNames` + `return false`). + → **Test 1 goes red** on every assertion (`assertTrue(res)` first: gets `false`; + `verify(never()).logCreateTable` fails: editlog written; `resetMetaCacheNamesCount` becomes 1). + This is precisely the DG-6 production bug, so the test cannot pass while the bug is present. +- Second mutation: change `exists = getTableHandle(...).isPresent() || getTableNullable(...) != null` + to drop the `|| getTableNullable(...) != null` arm. → **Test 2 goes red** (remote stub is + empty, so `exists` becomes `false`, falls into the new-table path, `createTable` gets called). + Encodes the local-cache parity intent. + +## E2E Tests + +`regression-test/suites/...` — the truth-gate is a live ODPS run (CI-skipped, per the standing +e2e policy; no e2e is exercised in CI). Intent to verify when a live ODPS env is available: + +1. `CREATE TABLE IF NOT EXISTS mc_existing AS SELECT * FROM src;` against a pre-existing + `mc_existing` → asserts the table's row count / contents are **unchanged** (no INSERT + occurred) and the statement returns OK. This is the end-to-end form of the silent-data-change + regression. (Pre-fix: rows from `src` get appended.) +2. `CREATE TABLE IF NOT EXISTS mc_new AS SELECT * FROM src;` for a fresh `mc_new` → table is + created and populated (new-table path intact). + +These belong alongside the existing MaxCompute CTAS / DDL suites; CI will skip the live-ODPS +suite. Note (Rule 12): UT alone cannot prove the absence of the downstream INSERT against a real +table — UT proves `createTable` returns `true` and the CTAS command's `if (...) return;` +short-circuits; the live e2e is what confirms no rows were written. diff --git a/plan-doc/tasks/designs/P4-T06e-FIX-DATETIME-PUSHDOWN-FORMAT-design.md b/plan-doc/tasks/designs/P4-T06e-FIX-DATETIME-PUSHDOWN-FORMAT-design.md new file mode 100644 index 00000000000000..5713f7c01f6dc5 --- /dev/null +++ b/plan-doc/tasks/designs/P4-T06e-FIX-DATETIME-PUSHDOWN-FORMAT-design.md @@ -0,0 +1,180 @@ +# [P4-T06e] FIX-DATETIME-PUSHDOWN-FORMAT (GAP0/1) — design + +> 来源：Batch-D 红线扩充对抗复审 workflow `wbw4xszrg`。用户定 **Fix（Tier 1，major correctness/perf）**。 +> 关联：legacy 对照 `MaxComputeScanNode.convertLiteralToOdpsValues:529-613`；fe-core 字面量来源 `ExprToConnectorExpressionConverter.convertDateLiteral:309-321`。 + +## Problem + +翻闸后，对 max_compute 表的 **DATETIME / TIMESTAMP / TIMESTAMP_NTZ** 列下推谓词坏。当 catalog 开启 `datetime_predicate_push_down`（默认开，见 `MCConnectorProperties.DEFAULT_DATETIME_PREDICATE_PUSH_DOWN`）时： + +```sql +-- 例：dt 为 DATETIME 列，session time_zone = 'Asia/Shanghai'（非 UTC） +SELECT * FROM mc.db.t WHERE dt = '2023-02-02 00:00:00'; +``` + +两条独立 delta（互不掩盖，须同修）： + +- **delta-1（format，perf + 可能错）**：谓词字面量被错误地序列化为 `LocalDateTime.toString()` 形态（`'T'` 分隔、变精度，如 `"2023-02-02T00:00"`），再喂给空格分隔、定长的 `DATETIME_3/6_FORMATTER` → + - **非 UTC session**：`LocalDateTime.parse` 抛 `DateTimeParseException` → 被顶层 `convert()` catch → **整棵 conjunct 树降为 `NO_PREDICATE`**（谓词永不下推 = 性能回归，全表扫 + BE 兜底过滤）。 + - **UTC session**：`convertDateTimezone` 短路返回未转换的 `"2023-02-02T00:00"` → 把 **malformed 字面量**推给 ODPS（`dt == "2023-02-02T00:00"`，结果未定：可能 ODPS 报错、可能匹配错/丢行）。 +- **delta-2（TZ source，丢行）**：source timezone 取 **project-region TZ**（由 endpoint URL 推），而 legacy 取 **session TZ**。当 session TZ ≠ project-region TZ 且 ≠ UTC 时，转换基准错位 → 推给 ODPS 的 UTC 字面量整体偏移 → **静默丢行 / 匹配错行**。仅 delta-1 修好后 delta-2 才会显形（否则谓词早已被丢）。 + +行正确性 + 性能双回归。仅 MaxCompute 暴露（唯一翻闸的 SPI 文件扫描连接器；`MaxComputePredicateConverter` 为 MC 专有类）。 + +## Root Cause（已核码确认） + +### delta-1：过早 stringify LocalDateTime + +| #

The Javadoc + at **:332-335** explicitly self-documents the gap: *"The SPI carries no `force`; + cascade semantics, if any, are left to the connector, so `force` is intentionally not + forwarded."* — but the connector does NOT cascade either (below). +- `fe/fe-connector/fe-connector-api/.../ConnectorSchemaOps.java:54-59` + the SPI only declares `default void dropDatabase(session, dbName, ifExists)` — there + is no `force`/cascade parameter, so the flag cannot even reach the connector. +- `fe/fe-connector/fe-connector-maxcompute/.../MaxComputeConnectorMetadata.java:415-420` + `dropDatabase(session, dbName, ifExists)` is just + `structureHelper.dropDb(odps, dbName, ifExists)` — no table enumeration, no cleanup. + `ProjectSchemaTableHelper.dropDb` (`McStructureHelper.java:195`) calls + `schemas().delete()`; `ProjectTableHelper.dropDb` (`:323-328`) throws "not supported" + (namespace-schema=false has no schemas to drop). + +**Effect:** with `force=true` on a non-empty schema, the cutover issues a bare +`schemas().delete()` against a schema that still has tables → ODPS rejects / residue. + +# Parity Reference + +Legacy code being mirrored — +`fe/fe-core/src/main/java/org/apache/doris/datasource/maxcompute/MaxComputeMetadataOps.java:132-157`: + +```java +public void dropDbImpl(String dbName, boolean ifExists, boolean force) throws DdlException { + ExternalDatabase dorisDb = dorisCatalog.getDbNullable(dbName); + if (dorisDb == null) { + if (ifExists) { LOG.info(...); return; } + else { ErrorReport.reportDdlException(ERR_DB_DROP_EXISTS, dbName); } + } + if (force) { // <-- cascade gate + List remoteTableNames = listTableNames(dorisDb.getRemoteName()); + for (String remoteTableName : remoteTableNames) { + ExternalTable tbl = null; + try { + tbl = (ExternalTable) dorisDb.getTableOrDdlException(remoteTableName); + } catch (DdlException e) { LOG.warn(...); continue; } // <-- skip-on-fail + dropTableImpl(tbl, true); // drop each table first + } + } + dorisCatalog.getMcStructureHelper().dropDb(odps, dbName, ifExists); // THEN delete schema +} +``` + +Two parity facts that bound the fix: +1. **Enumerate-then-drop ordering**: every table is dropped (with `ifExists=true`) + BEFORE `dropDb` deletes the schema. This is the behavior we must restore. +2. **FE-cache effect of the legacy force path is db-level ONLY**: legacy emits NO + per-table editlog and NO per-table `afterDropTable` for the cascaded tables — the + only FE bookkeeping is the single db-level `afterDropDb → unregisterDatabase` + (`MaxComputeMetadataOps.java:160-162`) plus the single `logDropDb` + (`ExternalCatalog.dropDb`). Therefore pushing the cascade entirely into the + connector (no per-table FE editlog) is exactly faithful to legacy — the plugin + path already emits the one `logDropDb` + `unregisterDatabase` + (`PluginDrivenExternalCatalog.java:352-353`), which is the complete legacy FE + bookkeeping. + +# Design + +**Chosen direction (honoring the user's decision): extend the SPI `dropDatabase` with +`force` and push the cascade into the connector — NOT an FE-side cascade.** + +Why this is correct and minimal: +- The cascade is inherently a remote-storage operation (enumerate ODPS tables, delete + each via the ODPS `tables().delete()` already used by `MaxComputeConnectorMetadata.dropTable`). + Pushing it into the connector keeps fe-core generic and confines MaxCompute-specific + semantics to the MaxCompute connector — matching how the cutover already routes + CREATE/DROP TABLE/DB through the SPI. +- An FE-side cascade would force fe-core to enumerate + per-table editlog, which is + EXTRA bookkeeping legacy never did (legacy cascade is editlog-silent per table) — so + the connector-side approach is *also* the closer parity match, not just the simpler one. +- **Additive-default SPI overload** (the established pattern used by P0-1/2/3 and + P1-4's 6-arg `planScan`): add a new 4-arg `dropDatabase(session, dbName, ifExists, + boolean force)` with a `default` body that delegates to the existing 3-arg form. The + other six connectors (es/jdbc/hive/hudi/iceberg/paimon/trino) never override + `ConnectorSchemaOps.dropDatabase` (verified: only MaxCompute does) and never call the + SPI form (they go through their own `metadataOps`), so they are ZERO-break: the + default 4-arg simply forwards to their inherited (or absent) 3-arg behavior. +- Only `MaxComputeConnectorMetadata` overrides the 4-arg to cascade. The cascade is + gated by `if (force)`; non-force preserves today's behavior verbatim. + +# Implementation Plan + +Ordered, file-by-file. SPI change first (api module), then connector, then fe-core +caller, then tests. + +### 1. SPI: add additive 4-arg overload +`fe/fe-connector/fe-connector-api/src/main/java/org/apache/doris/connector/api/ConnectorSchemaOps.java` + +After the existing 3-arg `dropDatabase` (ends at :59), add: + +```java +/** + * Drops the specified database, cascading to its tables when {@code force} is true. + * Default delegates to the non-cascading 3-arg form, so connectors that do not + * support cascade keep their current behavior with zero change. + */ +default void dropDatabase(ConnectorSession session, + String dbName, boolean ifExists, boolean force) { + dropDatabase(session, dbName, ifExists); +} +``` + +Keep the existing 3-arg `dropDatabase` unchanged (it is the delegation target and is +still used by the default). + +### 2. Connector: override the 4-arg to cascade +`fe/fe-connector/fe-connector-maxcompute/src/main/java/org/apache/doris/connector/maxcompute/MaxComputeConnectorMetadata.java:415-420` + +Decision on the existing 3-arg override: **fold the 3-arg into the 4-arg** to avoid two +methods that both touch `dropDb`. Replace the current 3-arg `dropDatabase` override with +the 4-arg override; the inherited `default` 3-arg will delegate into it. Concretely, +change the existing override signature from +`dropDatabase(ConnectorSession session, String dbName, boolean ifExists)` to +`dropDatabase(ConnectorSession session, String dbName, boolean ifExists, boolean force)` +and add the cascade: + +```java +@Override +public void dropDatabase(ConnectorSession session, String dbName, + boolean ifExists, boolean force) { + if (force) { + // ODPS schemas().delete() does NOT auto-cascade; enumerate and drop each + // table first (mirrors legacy MaxComputeMetadataOps.dropDbImpl force branch). + for (String tableName : structureHelper.listTableNames(odps, dbName)) { + try { + structureHelper.dropTable(odps, dbName, tableName, true); + } catch (OdpsException e) { + throw new DorisConnectorException("Failed to drop MaxCompute table '" + + tableName + "' during force-drop of database '" + dbName + + "': " + e.getMessage(), e); + } + } + } + structureHelper.dropDb(odps, dbName, ifExists); + LOG.info("dropped MaxCompute database {} (force={})", dbName, force); +} +``` + +Helper signatures confirmed present and already used in this class: +- `structureHelper.listTableNames(odps, dbName)` — used at `MaxComputeConnectorMetadata.java:102`. +- `structureHelper.dropTable(odps, dbName, tableName, true)` — used at `:398` + (single-table `dropTable`); declared `throws OdpsException` + (`McStructureHelper.java:73-74`), hence the try/catch wrapping into + `DorisConnectorException` exactly as the existing single-table `dropTable` override + does at `:399-401`. +- `structureHelper.dropDb(odps, dbName, ifExists)` — the existing terminal call (`:418`). + +Note on legacy skip-on-fail (`continue`): legacy logs+continues if it can't *resolve* +a Doris table wrapper, but its actual remote drop (`dropTableImpl`) is NOT swallowed. +Here there is no FE table-wrapper resolution step (we enumerate remote names directly), +so the only failure point is the remote `dropTable`, which we surface as +`DorisConnectorException` (fail loud, Rule 12) rather than silently continuing — this is +stricter than legacy only for the genuinely-failing-remote-drop case, which is the +correct fail-loud behavior. No imports change (`OdpsException`, `DorisConnectorException` +already imported, confirmed at `:25` and `:37`). + +### 3. fe-core caller: forward `force` +`fe/fe-core/src/main/java/org/apache/doris/datasource/PluginDrivenExternalCatalog.java:348` + +Change: +```java +connector.getMetadata(session).dropDatabase(session, dbName, ifExists); +``` +to: +```java +connector.getMetadata(session).dropDatabase(session, dbName, ifExists, force); +``` + +Also update the now-stale Javadoc at `:329-335` — replace the "force is intentionally +not forwarded" sentence with: "`force` is forwarded to the connector, which performs the +table cascade (mirroring legacy `MaxComputeMetadataOps.dropDbImpl`)." The surrounding +FE bookkeeping (`logDropDb` at :352, `unregisterDatabase` at :353) is unchanged — that +is the complete legacy db-level FE effect. + +### 4. FE routing test: update 3-arg stubs to 4-arg + add force-forwarding tests +`fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java` + +The FE caller will now call the 4-arg SPI, so the existing Mockito verify/doThrow stubs +that reference the 3-arg `dropDatabase` must move to the 4-arg form: +- **:139** `Mockito.verify(metadata).dropDatabase(session, "db1", false)` → + `Mockito.verify(metadata).dropDatabase(session, "db1", false, false)`. +- **:151** `Mockito.verify(metadata, Mockito.never()).dropDatabase(Mockito.any(), Mockito.any(), Mockito.anyBoolean())` + → add a 4th matcher: `..., Mockito.any(), Mockito.anyBoolean(), Mockito.anyBoolean())`. +- **:167** `Mockito.doThrow(...).when(metadata).dropDatabase(Mockito.any(), Mockito.any(), Mockito.anyBoolean())` + → `..., Mockito.any(), Mockito.anyBoolean(), Mockito.anyBoolean())`. + +Add two new tests in the DROP DATABASE section (mock `ConnectorMetadata`, so the default +delegation is irrelevant — we assert the exact 4-arg call): +- `testDropDbForceForwardsForceTrueToConnector` — `dropDb("db1", false, true)` then + `verify(metadata).dropDatabase(session, "db1", false, true)`. +- `testDropDbNonForceForwardsForceFalseToConnector` — `dropDb("db1", false, false)` then + `verify(metadata).dropDatabase(session, "db1", false, false)`. + +### 5. Connector cascade test (NEW) +`fe/fe-connector/fe-connector-maxcompute/src/test/java/org/apache/doris/connector/maxcompute/MaxComputeConnectorMetadataDropDbTest.java` + +The maxcompute test module has junit-jupiter but **NO mockito** (confirmed: no mockito +in `fe-connector-maxcompute/pom.xml`, connector parent, or api pom; no test uses +`org.mockito`). So the test uses a **hand-written recording fake `McStructureHelper`** +(implements the interface, records call order) — matching how +`MaxComputeBuildTableDescriptorTest` constructs the metadata offline with `null` odps. +The cascade code never dereferences `odps` (it only passes it to the fake helper), so +`null` odps is safe. See Test Plan for the exact tests. + +# Blast Radius + +**SPI overriders of `ConnectorSchemaOps.dropDatabase`** (grep across `fe/fe-connector/`): +only two files — `ConnectorSchemaOps.java` (declaration) and +`MaxComputeConnectorMetadata.java` (the sole override). The other six connectors +(es/jdbc/hive/hudi/iceberg/paimon/trino) do NOT override it and do NOT call the SPI form +(their DROP DB goes through `metadataOps.dropDb` / +`ExternalCatalog.dropDb:1037` / `PaimonMetadataOps.java:158` / `HiveMetadataOps.java:162`, +none of which touch `ConnectorSchemaOps`). The new 4-arg is a `default` that delegates to +the 3-arg, so: +- es/jdbc/hive/hudi/iceberg/paimon/trino: ZERO source change, ZERO behavior change + (they never reach this method; even if they did, the default preserves 3-arg behavior). +- MaxCompute: only connector whose behavior changes, and only on the `force==true` + branch (non-force is byte-for-byte the prior `dropDb` call). + +**Production callers of the SPI `dropDatabase`**: exactly one — +`PluginDrivenExternalCatalog.java:348` (the FE caller being updated). No other +production call site exists (the many `dropDatabase` hits in the grep are Hive/Glue/Datalake +metastore *clients*, an unrelated method on a different interface). + +**Tests whose assertions must change (signature change forces this):** +- `PluginDrivenExternalCatalogDdlRoutingTest.java:139,151,167` — the three 3-arg + `dropDatabase` stubs/verifies, as itemized in Implementation Plan step 4. These are + compile-or-verify breaks caused directly by the FE caller switching to the 4-arg form; + they are mandatory. + +No SPI method is removed; the 3-arg `dropDatabase` stays (it is the delegation target). +No fe-core public signature changes — `PluginDrivenExternalCatalog.dropDb` already had +`force` in its signature. + +# Risk Analysis + +1. **Cross-module rebuild ordering.** SPI lives in `fe-connector-api`. A signature + *addition* (additive default) does not break binary compat for the existing 3-arg + callers, but the new call site in fe-core and the new override in maxcompute both + reference the 4-arg, so api + maxcompute + fe-core must be rebuilt together + (`-am`). Mitigation: build order in Test Plan. + +2. **dbName local-vs-remote name resolution (pre-existing, out of scope).** Legacy + enumerates via `dorisDb.getRemoteName()` and drops via `dorisTable.getRemoteName()`, + whereas `PluginDrivenExternalCatalog.dropDb` passes the **local** `dbName` straight to + the SPI (it does NOT remote-resolve, unlike the `dropTable`/`createTable` overrides at + :390/:279). The cascade therefore enumerates against whatever name the FE passes. For + a non-name-mapped catalog (the common case) local==remote and behavior is correct. + For a name-mapped catalog this is a latent bug — but it is **identical to and + inherited from the already-shipped non-force 3-arg path** (which also passes local + dbName to `dropDb`). Per Rule 3 (surgical) this fix does NOT widen scope to remote- + resolve dbName; doing so would change the existing non-force path too. Surfaced as an + open question (see below) and flagged for the DG-3/DG-4 DB-DDL triage batch. + +3. **Partial cascade on mid-loop failure.** If table N's remote drop throws, tables + 1..N-1 are already gone and the schema is NOT deleted (we throw before `dropDb`). + This is a fail-loud partial state — but it matches legacy's exposure (legacy's + `dropTableImpl` could equally throw mid-loop) and is the correct behavior vs silently + leaving residue. The DdlException surfaces to the user. + +4. **namespace-schema=false mode.** `ProjectTableHelper.dropDb` throws "not supported" + (`McStructureHelper.java:323-328`). With `force=true` in that mode, we now enumerate + + dropTable first, then hit the same "not supported" on `dropDb`. Net behavior is the + same terminal error as today (CREATE/DROP DB is unsupported without namespace-schema); + the extra table drops before the throw are harmless because that mode realistically + isn't used for DROP DB at all. No regression vs current. + +5. **Live ODPS truth-gate.** UT verifies routing + cascade ordering with fakes/mocks; + it cannot verify ODPS actually rejects non-empty `schemas().delete()`. That remains + the standing live-e2e truth gate (CI-skip). + +# Test Plan + +## Unit Tests + +### A. FE routing — `PluginDrivenExternalCatalogDdlRoutingTest` (fe-core) +File: `fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java` +Class: `PluginDrivenExternalCatalogDdlRoutingTest` + +- **(edit) testDropDbRoutesToConnectorAndUnregisters** (:134) — change the :139 verify + to `dropDatabase(session, "db1", false, false)`. WHY: the FE caller now uses the 4-arg + SPI; this keeps the existing routing+unregister assertion valid against the new signature. +- **(edit) testDropDbIfExistsWhenMissingIsNoop** (:145) — change :151 `never()` matcher + to the 4-arg form. WHY: keeps "missing db + IF EXISTS never touches the connector" + meaningful against the new signature. +- **(edit) testDropDbWrapsConnectorException** (:163) — change :167 `doThrow...when` + matcher to the 4-arg form. WHY: keeps "connector failure → DdlException" wrapping + guarded against the new signature. +- **(new) testDropDbForceForwardsForceTrueToConnector** — `catalog.dbNullableResult = + mock; catalog.dropDb("db1", false, true);` then + `verify(metadata).dropDatabase(session, "db1", false, true)`. WHY (Rule 9): the + regression is that `force` was silently dropped (Rule 12 violation / lost cascade); + this asserts the user's `FORCE` intent actually reaches the connector. +- **(new) testDropDbNonForceForwardsForceFalseToConnector** — same but `force=false` + → `verify(metadata).dropDatabase(session, "db1", false, false)`. WHY: guards that the + fix does NOT spuriously cascade a non-FORCE drop (over-correction would be a new bug). + +MUTATION check: reverting `PluginDrivenExternalCatalog.java:348` to pass a hardcoded +`false` (or back to the 3-arg form) makes **testDropDbForceForwardsForceTrueToConnector** +go red (verify sees `force=false`/no 4-arg call, not `true`). + +### B. Connector cascade — `MaxComputeConnectorMetadataDropDbTest` (fe-connector-maxcompute, NEW) +File: `fe/fe-connector/fe-connector-maxcompute/src/test/java/org/apache/doris/connector/maxcompute/MaxComputeConnectorMetadataDropDbTest.java` +Class: `MaxComputeConnectorMetadataDropDbTest` + +Harness: NO mockito in this module → use a hand-written recording fake +`RecordingStructureHelper implements McStructureHelper` that (a) returns a fixed table +list from `listTableNames`, (b) appends `"dropTable:"` to an ordered `List` +log on each `dropTable`, (c) appends `"dropDb:"` on `dropDb`. Construct +`new MaxComputeConnectorMetadata(null /*odps*/, fake, "proj", "ep", "quota", emptyMap)` +(same offline pattern as `MaxComputeBuildTableDescriptorTest`). Call the 4-arg +`dropDatabase` directly. + +- **forceTrueCascadesAllTablesBeforeDroppingSchema** — fake `listTableNames` returns + `["t1","t2"]`; call `dropDatabase(session, "db1", false, true)`; assert the recorded + log equals `["dropTable:t1", "dropTable:t2", "dropDb:db1"]` (per-table drops, in order, + all BEFORE the schema delete). WHY (Rule 9): encodes the legacy parity requirement that + ODPS does NOT auto-cascade, so every table must be dropped first — the exact regression + DG-3 describes. MUTATION: removing the `if (force) { ...enumerate/dropTable... }` block + in `MaxComputeConnectorMetadata.dropDatabase` makes this red (log becomes just + `["dropDb:db1"]`). +- **forceFalseDoesNotEnumerateOrDropTables** — fake `listTableNames` returns + `["t1","t2"]` (would-be tables present); call `dropDatabase(session, "db1", false, + false)`; assert the log equals `["dropDb:db1"]` (no `dropTable`, no enumeration). WHY: + guards that non-FORCE never cascades — a regression in the other direction (always + cascading) would silently delete tables on a plain DROP DB. MUTATION: changing the gate + from `if (force)` to unconditional makes this red. +- **forceTrueOnEmptySchemaJustDropsDb** — fake `listTableNames` returns `[]`; call with + `force=true`; assert log equals `["dropDb:db1"]`. WHY: FORCE on an empty schema must + behave like a plain drop (no spurious table calls) — confirms the loop is a no-op when + there are no tables. +- **forceTrueSurfacesRemoteDropFailureAsConnectorException** — fake `dropTable` throws + `OdpsException` for `t2`; assert `dropDatabase(session,"db1",false,true)` throws + `DorisConnectorException` whose message contains `t2`, AND that `dropDb` was NOT + recorded (schema not deleted after a failed cascade). WHY (Rule 12, fail-loud): a + failing remote drop must not be swallowed and must abort before deleting the schema — + the opposite of the silent-degradation regression. MUTATION: swallowing the + `OdpsException` (catch+continue without rethrow) makes this red. + +## E2E Tests + +No new e2e file is strictly required for UT-level parity, but the standing truth-gate is +live ODPS (CI-skip). If an e2e suite is added it belongs under +`regression-test/suites/external_table_p2/maxcompute/` (mirroring existing MC suites): +- `test_mc_drop_db_force` — create a `max_compute` schema, create ≥2 tables, run + `DROP DATABASE FORCE`, assert it succeeds and the schema + tables are gone; + and that `DROP DATABASE ` (non-force) on a non-empty schema fails. CI-skip + (requires real ODPS credentials/quota); this is the only layer that proves ODPS + `schemas().delete()` truly rejects a non-empty schema, which the loop exists to avoid. diff --git a/plan-doc/tasks/designs/P4-T06e-FIX-ISKEY-METADATA-design.md b/plan-doc/tasks/designs/P4-T06e-FIX-ISKEY-METADATA-design.md new file mode 100644 index 00000000000000..836d7b29b5abf3 --- /dev/null +++ b/plan-doc/tasks/designs/P4-T06e-FIX-ISKEY-METADATA-design.md @@ -0,0 +1,158 @@ +# P4-T06e FIX-ISKEY-METADATA — Design + +> Issue: P3-10 / NG-6 / F3 / F10 (minor, read/metadata, regression).

(Same + pattern the JDBC connector already uses for `jdbc_clickhouse_query_final`, + `enable_odbc_transcation`, etc. — the connector hardcodes the var-name string; it must not + depend on fe-core's `SessionVariable` constant, per import-gate.) +- **Gate (2) — only-partition-equality.** The `filter` passed to `planScan` is + `buildRemainingFilter()` → `ExprToConnectorExpressionConverter.convertConjuncts(...)`: + - empty conjuncts → `Optional.empty()` (handled by the `!filter.isPresent()` arm). + - 1 conjunct → the bare converted node. + - N conjuncts → a **flat** `ConnectorAnd` (count preserved; `convertConjuncts` never drops a + conjunct — unknown types become `ConnectorFunctionCall`). + - MaxCompute uses the **default** `supportsCastPredicatePushdown = true`, so `buildRemainingFilter` + takes the `else` branch and passes the **full** conjunct set (no whole-conjunct drops).

Post-cutover the same command throws before reaching the (fully +wired) write machinery. + +## Root Cause + +`allowInsertOverwrite` is a pure `instanceof` allow-list of *legacy* table classes. The cutover +replaced the concrete `MaxComputeExternalTable` with the generic `PluginDrivenExternalTable`, but +this gate was never extended to recognise the generic SPI table type. The lower OVERWRITE machinery +*was* extended (it already has a `UnboundConnectorTableSink` branch — see below), so this is a +classic "dispatch only half-wired": the entry gate rejects what the body already supports. + +### The lower machinery is already complete (one-gate change confirmed) + +Once the gate passes, the path is fully wired for the plugin/connector case: + +1. `run()` (`:157-160`) calls `InsertUtils.normalizePlan(...)`. For a `PluginDrivenExternalCatalog`, + the parsed `INSERT OVERWRITE` plan is an `UnboundConnectorTableSink` + (`UnboundTableSinkCreator.java:68-69, :108-110, :149-151` all map + `curCatalog instanceof PluginDrivenExternalCatalog` → `UnboundConnectorTableSink`; + `InsertUtils.normalizePlan` handles it at `InsertUtils.java:609-610`). +2. The non-OLAP branch at `run()` `:215-218` sets `partitionNames = []` (FE does not create temp + partitions for external tables), and the flow enters `insertIntoPartitions(...)` via `:241-279`. +3. `insertIntoPartitions` (`:345-444`) dispatches on the sink type. The + `UnboundConnectorTableSink` branch (`:420-440`) rebuilds the sink, creates a + `PluginDrivenInsertCommandContext`, sets `overwrite=true`, and copies the static-partition spec + from `sink.getStaticPartitionKeyValues()`. This is the genuine OVERWRITE wiring — it just is + never reached today. + +So the fix is a single gate edit. No change to the body, the sink, the context, or the translator. + +## Design + +### The change + +Add a `PluginDrivenExternalTable` branch to `allowInsertOverwrite`: + +```java +private boolean allowInsertOverwrite(TableIf targetTable) { + if (targetTable instanceof OlapTable || targetTable instanceof RemoteDorisExternalTable) { + return true; + } else { + return targetTable instanceof HMSExternalTable + || targetTable instanceof IcebergExternalTable + || targetTable instanceof MaxComputeExternalTable + || targetTable instanceof PluginDrivenExternalTable; + } +} +``` + +### Predicate choice — `instanceof PluginDrivenExternalTable` (Rule 7, Rule 2) + +The re-review (§NG-1 处置) phrased the predicate as "key on the SPI generic type; whether OVERWRITE +is supported is decided by whether downstream produces an `UnboundConnectorTableSink`." Examining the +actual code, those two phrasings collapse to the *same* predicate: + +- `UnboundTableSinkCreator` produces an `UnboundConnectorTableSink` **iff** + `curCatalog instanceof PluginDrivenExternalCatalog` (`:68`, `:108`, `:149`) — there is **no** + capability flag or table-level toggle in that decision. +- A `PluginDrivenExternalTable` always belongs to a `PluginDrivenExternalCatalog` (its ctor and all + metadata accessors cast `catalog` to `PluginDrivenExternalCatalog`). +- Therefore "table is `PluginDrivenExternalTable`" ⇔ "downstream produces `UnboundConnectorTableSink`" + ⇔ "the `:420-440` OVERWRITE branch will fire". The `instanceof` is the faithful, minimal encoding + of the report's "downstream produces UnboundConnectorTableSink" criterion. + +**Alternative considered — capability-gated** (`ConnectorCapability.SUPPORTS_INSERT`): +`ConnectorCapability` already exists and has `SUPPORTS_INSERT` (`ConnectorCapability.java:30`), and +`PluginDrivenExternalTable.supportsParallelWrite()` (`:78-85`) shows the established pattern for +reading capabilities. We could gate the branch on +`((PluginDrivenExternalCatalog) catalog).getConnector().getCapabilities().contains(SUPPORTS_INSERT)`. + +Rejected for this fix, because: +1. **It would not match the current contract.** No other downstream component (the sink creator, the + BindSink connector branch, `InsertUtils`) consults `SUPPORTS_INSERT` before producing/binding a + connector sink. Gating *only* the OVERWRITE gate on the capability would make OVERWRITE stricter + than plain INSERT, which is inconsistent and surprising. A capability check, if wanted, belongs in + the sink-creation layer (`UnboundTableSinkCreator`) so that INSERT and OVERWRITE share it — that + is a separate, broader change, out of scope for a regression fix. +2. **Rule 2 (simplicity) / Rule 11 (match conventions).** Every other arm of `allowInsertOverwrite` + is a bare `instanceof` (OlapTable / RemoteDoris / HMS / Iceberg / MaxCompute — `:316-321`); none + gates on a capability or write-support flag. A bare `instanceof PluginDrivenExternalTable` matches + the surrounding style exactly. If the underlying connector genuinely cannot write, the failure + surfaces deterministically deeper in the write path (BE / connector sink), exactly as it would for + plain INSERT today — the gate is not the right place to pre-empt that. +3. **The report's literal criterion is the `UnboundConnectorTableSink`, not a capability** — and that + is what `instanceof PluginDrivenExternalTable` encodes (see above equivalence). + +**Recommendation:** `instanceof PluginDrivenExternalTable`. This is the simplest predicate that is +*correct against the actual downstream dispatch* and consistent with both the existing arms of this +method and the FIX-PART-GATES decision① principle ("key on the SPI type, do not over-broaden"). Note +the contrast with FIX-PART-GATES decision①: there the override was *shared* by jdbc/es/trino/MC, so +an unconditional `true` would have flipped non-MC behavior, and the predicate had to be narrowed +(`!getPartitionColumns().isEmpty()`). Here the predicate already *is* type-scoped — `instanceof +PluginDrivenExternalTable` only fires for plugin tables — and the downstream is uniformly wired for +all of them, so no further narrowing is warranted or beneficial. + +### Shared-override / blast-radius note (jdbc/es/trino) + +`allowInsertOverwrite` is **not** an override shared across table classes — it is a private method of +`InsertOverwriteTableCommand` keyed on `instanceof`. Adding the branch only changes behavior for +tables that are `PluginDrivenExternalTable` (jdbc, es, trino-connector, max_compute after cutover). +For jdbc/es/trino this *enables* the OVERWRITE entry gate where it was previously rejected — but the +downstream is identical for all of them: they all flow through the same `UnboundConnectorTableSink` → +`PluginDrivenInsertCommandContext(overwrite=true)` branch (`:420-440`). If a given connector cannot +actually perform an overwrite, it fails at the connector/BE write layer with a connector-specific +error, exactly as a plain INSERT into a write-incapable connector does today. The gate is not the +behavioral firewall for "can this connector write" — the connector itself is. This is the same +semantics legacy had: legacy gated only on `instanceof MaxComputeExternalTable` because MC was the +only connector-style table; the generic replacement is `instanceof PluginDrivenExternalTable`. + +## Implementation Plan + +**File:** `fe/fe-core/src/main/java/org/apache/doris/nereids/trees/plans/commands/insert/InsertOverwriteTableCommand.java` + +**Method:** `allowInsertOverwrite(TableIf)` (`:315-323`). + +**Edit** — append one `instanceof` arm to the `else` return (`:319-321`): + +```java + return targetTable instanceof HMSExternalTable + || targetTable instanceof IcebergExternalTable + || targetTable instanceof MaxComputeExternalTable + || targetTable instanceof PluginDrivenExternalTable; +``` + +**Import to add:** +`import org.apache.doris.datasource.PluginDrivenExternalTable;` + +**Import placement / checkstyle (CustomImportOrder: doris → third-party → java; UnusedImports; +LineLength 120):** the new import is in the `org.apache.doris.datasource.*` block.

Insert it as the **first** line of that block, i.e. +immediately before `:29`. (Confirm against `checkstyle:check`; if the project's import comparator is +case-insensitive the line may instead sort after the `maxcompute` line — let checkstyle dictate the +exact slot.) + +No other edits. The branch body and all downstream wiring are unchanged. + +## Risk Analysis + +- **Blast radius — non-MC plugin connectors (jdbc/es/trino):** This change lets jdbc/es/trino-backed + `PluginDrivenExternalTable`s pass the OVERWRITE *entry* gate. Pre-cutover those were legacy + `JdbcExternalTable` / `EsExternalTable` / `TrinoConnectorExternalTable`, which were **never** in + `allowInsertOverwrite` — so for them this is a *new* code path being opened, not a parity + restoration. Mitigation/justification: the downstream is uniform (all plugin catalogs produce + `UnboundConnectorTableSink`), and a connector that cannot overwrite fails deterministically at the + bind/BE layer with a connector-specific error — the same place plain INSERT fails for a + write-incapable connector. The gate is intentionally not the per-connector write-capability check. + If product wants OVERWRITE locked down per-connector, that belongs in `UnboundTableSinkCreator` + (shared by INSERT + OVERWRITE), not here — flagged, out of scope. +- **Batch-D red-line interaction (🔴):** Batch-D plans to delete the legacy + `instanceof MaxComputeExternalTable` arm (`:321`) from this method + (`P4-batchD-maxcompute-removal-design.md` §2, file row for `InsertOverwriteTableCommand.java`). + That deletion is safe **only after** this fix adds the `PluginDrivenExternalTable` arm — otherwise + the gate loses *all* coverage for MaxCompute tables (legacy class is gone post-cutover anyway, and + the generic arm would not yet exist) and `INSERT OVERWRITE` breaks permanently. Ordering: this fix + must land *before* the Batch-D delete-branch edit for `:321`. **Doc-sync flag below.** +- **What can still fail at BE/live (real truth-gate):** This fix only proves the FE entry gate is + passable. The actual OVERWRITE execution (static-partition spec honored, partition replace + semantics, affected-rows, MC `INSERT OVERWRITE` vs `INSERT INTO ... OVERWRITE` mapping) is BE + + connector + ODPS, and per the re-review (§NG-1 note, §E#5/#6) the truth-gate is **live e2e against + real ODPS, which CI skips**. The re-review also flags adjacent write blockers (NG-2/NG-4 dynamic + partition GATHER/local-sort, NG-3 static-partition bind) that this fix does *not* address — a green + gate here does not imply a green end-to-end OVERWRITE until those are fixed and run live. + This fix is necessary-but-not-sufficient for working OVERWRITE; it removes the first (FE) blocker. + +## Test Plan + +### Unit Tests + +**Location:** new test class +`fe/fe-core/src/test/java/org/apache/doris/nereids/trees/plans/commands/insert/InsertOverwriteTableCommandTest.java` +(no existing unit test targets `allowInsertOverwrite` — verified; this is the package home of the +command under test). + +`allowInsertOverwrite(TableIf)` is `private` and field-independent (it inspects only its argument), +so invoke it directly via the project's established private-method test helper +`org.apache.doris.common.jmockit.Deencapsulation.invoke(instance, "allowInsertOverwrite", table)` +(pattern: `transaction/TableStreamOffsetTransactionTest.java:112`). Construct the command with any +minimal `LogicalPlan` (the ctor only requires a non-null `logicalQuery`; `allowInsertOverwrite` never +touches it — use a mock/stub `LogicalPlan` or a trivial unbound sink). Build the +`PluginDrivenExternalTable` with the mock-catalog pattern from +`PluginDrivenExternalTablePartitionTest` (`TestablePluginCatalog("max_compute", ...)` + a +`PluginDrivenExternalTable` anonymous subclass that no-ops `makeSureInitialized()`), so no Doris env +is required. + +**Test 1 — `allowInsertOverwriteAcceptsPluginDrivenTable` (the Rule-9 red-before / green-after test):** +- Arrange: a `PluginDrivenExternalTable` backed by a `max_compute` `TestablePluginCatalog`. +- Act: `boolean allowed = Deencapsulation.invoke(cmd, "allowInsertOverwrite", table);` +- Assert: `assertTrue(allowed, "INSERT OVERWRITE into a cutover MaxCompute (PluginDrivenExternalTable) must pass the gate; legacy MaxComputeExternalTable did")`. +- **Why it encodes intent (Rule 9):** it asserts the *business* invariant "cutover MaxCompute tables + retain INSERT OVERWRITE support that legacy had" — not merely "method returns a boolean". +- **Mutation / red-before proof:** remove the new `|| targetTable instanceof PluginDrivenExternalTable` + arm (i.e. revert the production change) → `allowInsertOverwrite` returns `false` for a + `PluginDrivenExternalTable` → this assertion goes **red**. With the arm present it is green. This is + the loop's red-before/green-after gate. + +**Test 2 (optional parity guard) — `allowInsertOverwriteStillRejectsUnsupportedType`:** +- Arrange: a `TableIf` that is none of the allow-listed types (e.g. a mock `TableIf`, or any + internal table type not in the list). +- Assert: `assertFalse(...)`. +- **Why:** pins that the new arm did not accidentally broaden to "all external tables" — a mutation + that replaced the targeted `instanceof` with an unconditional `true` would make this red.

This is heavier (needs more of `run()`'s collaborators) and is +not required — Test 1 already gives the deterministic red-before/green-after gate. Prefer Test 1 + +Test 2 for the loop. + +**Out of scope for this loop (state explicitly):** end-to-end `INSERT OVERWRITE` execution against +real ODPS (`external_table_p2/maxcompute/*`). Per §Risk, that is the real truth-gate but requires +live credentials and is CI-skipped; it is not part of this fix's unit-test loop. + +--- + +# Round 2 revision (2026-06-07) — narrow predicate via SPI capability (user decision = Option A) + +**Why revised:** round-1 clean-room adversarial review (`w5ke8sjaq`) confirmed (2/2) that the bare +`instanceof PluginDrivenExternalTable` predicate also admits **JDBC** (which is `PluginDrivenExternalTable` +post-cutover, `supportsInsert()=true` but `getWriteConfig` never propagates the overwrite flag) → +`INSERT OVERWRITE` **silently degrades to a plain INSERT (data loss)**.

limit-opt（`getSplitsWithLimitOptimization(requiredPartitionSpecs)` @`:737`）同样接收裁剪集。 + +### 3) fe-core — `PluginDrivenScanNode` +- 新增字段 `private SelectedPartitions selectedPartitions =

This +is the write-path face of the recurring "half-wired dispatch" (re-review §C domain-6): the read/DDL +dispatch was generalized, the write *distribution* was not. + +## Design + +### Two orthogonal connector signals → two capabilities + +The legacy 3-branch needs exactly two connector-declared facts, which I map to **`ConnectorCapability` +enum** values read through `connector.getCapabilities()` — the *same* mechanism the sibling +`supportsParallelWrite()` already uses (read in this very method), so both reads are uniform and +require no `ConnectorSession`/metadata construction in the planner property-derivation hot path: + +1. **`SUPPORTS_PARALLEL_WRITE`** (already exists, `ConnectorCapability.java:51`) — "multiple + concurrent writers are safe." Drives the non-partition / all-static → `SINK_RANDOM_PARTITIONED` + branch. **MaxCompute must now declare it** (fixes NG-4). Read via the existing + `PluginDrivenExternalTable.supportsParallelWrite()`. +2. **`SINK_REQUIRE_PARTITION_LOCAL_SORT`** (NEW enum value) — "dynamic-partition writes must be + hash-distributed and locally sorted by partition columns" (the MaxCompute Storage-API streaming + constraint). Drives branch-1. **MaxCompute declares it** (fixes NG-2). Read via a new + `PluginDrivenExternalTable.requirePartitionLocalSortOnWrite()`. + +Default for the new capability is **absent/false** → no behavior change for any other connector +(jdbc/es/trino: neither capability → still GATHER), mirroring the FIX-OVERWRITE-GATE +default-false-opt-in philosophy. The two capabilities are intended to be declared **together** by a +partition-writing connector (hash distribution is inherently parallel); the sink does not force that +pairing (branch-1 keys only on the local-sort capability, faithful to legacy's unconditional +dynamic→hash+sort), but the design note records the intended pairing. + +### The fe-core sink logic — **critical correction vs legacy: index by `cols`, not full-schema** + +> ⚠️ **SUPERSEDED by P0-3 / FIX-BIND-STATIC-PARTITION ([D-030], 2026-06-07).** This section's "index by +> `cols`" decision was **reverted to legacy full-schema indexing**. Reason: P0-3 makes +> `bindConnectorTableSink` project the child to **full-schema** order for positional-write connectors +> (MaxCompute, gated by capability `SINK_REQUIRE_FULL_SCHEMA_ORDER`), so `child().getOutput()` is again +> aligned with `table.getFullSchema()` — *not* `cols` (cols excludes static partition cols and may be +> user-reordered). `cols`-indexing silently shuffled by the wrong column in the partial-static and +> reordered-explicit-list cases. The "`cols.size() == child output size`" invariant below holds only for +> the non-positional (JDBC/ES) path. See `reviews/P4-T06e-FIX-BIND-STATIC-PARTITION-review-rounds.md`. + +The generic sink's `getRequirePhysicalProperties()` reproduces the legacy 3-branch, **but the +partition-column → child-output index mapping MUST differ from legacy.** This is the single most +important correctness point of this fix: + +- Legacy `bindMaxComputeTableSink` (`BindSink.java:904-906`) projects the child to **full-schema** + order (`getOutputProjectByCoercion(table.getFullSchema(), ...)`), so legacy + `PhysicalMaxComputeTableSink` can index `child().getOutput().get(fullSchemaIdx)`. +- The generic `bindConnectorTableSink` (`BindSink.java:949-950`) projects the child to **`bindColumns`** + order (`getOutputProjectByCoercion(bindColumns, ...)`), where `bindColumns == boundSink.getCols()`, + and enforces `cols.size() == child.getOutput().size()` (`:941`). So for the generic sink + `child().getOutput().get(i)` corresponds to **`cols.get(i)`**, NOT to `fullSchema.get(i)`. + +Therefore the generic sink finds each partition column by its index **in `cols`** and reads the +aligned child output slot at the same index: + +```java +@Override +public PhysicalProperties getRequirePhysicalProperties() { + if (!(targetTable instanceof PluginDrivenExternalTable)) { + return PhysicalProperties.GATHER; + } + PluginDrivenExternalTable table = (PluginDrivenExternalTable) targetTable; + + // Branch 1 — dynamic-partition write that the connector requires to be hash-distributed and + // locally sorted by partition columns (MaxCompute Storage API streams partition writers and + // errors on unsorted multi-partition data — mirrors legacy PhysicalMaxComputeTableSink). + if (table.requirePartitionLocalSortOnWrite()) { + Set partitionNames = table.getPartitionColumns().stream() + .map(Column::getName).collect(Collectors.toSet()); + if (!partitionNames.isEmpty()) { + // Index by cols (== child output alignment for the connector sink), NOT full schema. + List partitionColIdx = new ArrayList<>(); + for (int i = 0; i < cols.size(); i++) { + if (partitionNames.contains(cols.get(i).getName())) { + partitionColIdx.add(i); + } + } + if (!partitionColIdx.isEmpty()) { // a partition col present in cols == dynamic write + List exprIds = partitionColIdx.stream() + .map(idx -> child().getOutput().get(idx).getExprId()) + .collect(Collectors.toList()); + DistributionSpecHiveTableSinkHashPartitioned shuffleInfo = + new DistributionSpecHiveTableSinkHashPartitioned(); + shuffleInfo.setOutputColExprIds(exprIds); + List orderKeys = partitionColIdx.stream() + .map(idx -> new OrderKey(child().getOutput().get(idx), true, false)) + .collect(Collectors.toList()); + return new PhysicalProperties(shuffleInfo) + .withOrderSpec(new MustLocalSortOrderSpec(orderKeys)); + } + // partition cols exist but none in cols == all-static: fall through. + } + } + + // Branch 2/3 — non-partition or all-static: parallel writers if the connector supports it. + if (table.supportsParallelWrite()) { + return PhysicalProperties.SINK_RANDOM_PARTITIONED; + } + return PhysicalProperties.GATHER; +} +``` + +Result mapping: + +| table / write shape | caps declared | output | legacy parity | +|---|---|---|---| +| MaxCompute, dynamic partition | both | hash(part) + local-sort(part) | ✅ = legacy branch-1 | +| MaxCompute, all-static partition | both | `SINK_RANDOM_PARTITIONED` | ✅ = legacy branch-2 | +| MaxCompute, non-partitioned | both | `SINK_RANDOM_PARTITIONED` | ✅ = legacy branch-3 | +| jdbc / es / trino | none | `GATHER` | ✅ unchanged | + +### Why no change is needed in `RequestPropertyDeriver` + +`RequestPropertyDeriver.visitPhysicalConnectorTableSink():212-227` already routes correctly: +`GATHER → GATHER`; else (with `enableStrictConsistencyDml`, default **true** — +`SessionVariable.java:1566`) `→ getRequirePhysicalProperties()` to children. So once +`getRequirePhysicalProperties()` returns hash+local-sort, the deriver enforces it (inserts the +shuffle + local sort) exactly as it does for legacy `visitPhysicalMaxComputeTableSink():180-188`. The +non-strict (`enable_strict_consistency_dml=false`) path pushes `ANY` for **both** legacy MC and the +generic connector sink — i.e. it drops the requirement identically in legacy and cutover, so it is a +pre-existing parity, not a regression introduced here. (A user who turns off strict-consistency DML +loses local-sort on dynamic partitions in legacy too; default-on covers the common case.) + +### Known minor divergence — `ShuffleKeyPruner` (documented, not fixed here) + +`ShuffleKeyPruner.visitPhysicalConnectorTableSink():286-295` lacks the non-strict short-circuit that +`visitPhysicalMaxComputeTableSink():272-283` has. In the **default strict** mode both compute +`childAllowShuffleKeyPrune = required.equals(ANY)` → `false` for a dynamic-partition write → **identical +behavior**. They diverge **only** when `enable_strict_consistency_dml=false`: legacy prunes shuffle keys +(`true`), generic does not (`required` is hash+sort ≠ `ANY` → `false`). The generic path therefore +prunes **less** (more conservative) — a missed optimization, never a correctness issue, and it is +**pre-existing** (the generic branch already differs; this fix does not introduce it). Recorded as a +minor deviation; aligning it would touch the shared connector branch for jdbc/es and is out of scope. + +### Coupling with P0-3 (FIX-BIND-STATIC-PARTITION) — correct either way, fully exercised only after P0-3 + +The dynamic/static detection reads `cols` and relies on the contract *"static partition columns are +excluded from `cols`"* — the same contract legacy `getRequirePhysicalProperties()` relies on (legacy +`bindMaxComputeTableSink:876-879` excludes them). The generic `bindConnectorTableSink` does **not** yet +exclude them (that is the P0-3 bug, NG-3). Consequences, both **safe**: + +- `INSERT INTO mc PARTITION(p='x') SELECT ` (no column list, all-static): today + this **fails at bind** (`cols` includes `p`, child output excludes it → `:941` count mismatch + throws) — so `getRequirePhysicalProperties()` is **never reached**. After P0-3, `cols` excludes the + static `p` → branch falls through to `SINK_RANDOM_PARTITIONED`. ✅ either way. +- `INSERT INTO mc PARTITION(p) SELECT ... , p_val` (dynamic): `p` is in `cols` → branch-1 + hash+local-sort. ✅ today and after P0-3. +- Mixed `PARTITION(p1='x', p2) SELECT ...`: after P0-3, `cols` excludes static `p1`, includes dynamic + `p2` → hash+sort by `p2` only. Legacy hashes+sorts by `{p1,p2}` but `p1` is a projected constant, so + `{p2}` ≡ `{p1,p2}` for grouping. ✅ functionally equivalent. + +So **this fix is correct regardless of P0-3 ordering**; it is merely not *exercised* for the all-static +no-column-list shape until P0-3 lands.

Simpler (Rule 2), but forces the MaxCompute Storage-API local-sort + policy on **every** future parallel-write partitioned connector, even ones that buffer per-partition + and don't need it (an unnecessary sort cost).

All gates green: test-compile (main+test), checkstyle 0, import-gate, grep-empty (`com.aliyun.odps` in fe-core/src = ∅, no non-comment refs), and `mvn -pl :fe-core dependency:tree | grep odps` = ∅. §8 surfaced a hidden transitive leak — odps-sdk-core was also providing netty/protobuf to fe-common's own DorisHttpException/GsonUtilsBase; fixed by declaring them directly (see [DV-022]).

The conclusion (fix is legacy-equivalent and safe) is unchanged and verified, but the supporting statement 'grep 全证实 ... 只 流向两处' is wrong and should be corrected. +- Minor: the design says the fix mirrors legacy MaxComputeScanNode.java:659 length=-1; verified accurate -- legacy constructor MaxComputeSplit(BYTE_SIZE_PATH, splitIndex, -1, splitByteSize, ...) puts -1 in arg3 (length) and splitByteSize in arg4 (fileLength, unread by BE). Connector after fix is byte-exact (setSize=-1, setStartOffset=splitIndex, path='[ splitIndex , -1 ]'). No correction needed to the core claim. + +**遗漏(gaps)**: +- Risk analysis omits a third consumer of getLength(): PluginDrivenSplit.java:42 passes scanRange.getLength() into the FileSplit.length field. The design's repeated claim that splitByteSize/getLength flows ONLY into setPath(:120) and setSize(:122) ('grep fully confirms') is factually incomplete. FileSplit.length is consumed downstream by FederationBackendPolicy.java:499 (primitiveSink.putLong(split.getLength()) in consistent-hash backend assignment) and FileQueryScanNode.java:430 (totalFileSize += split.getLength()). After the fix these see -1 instead of 268435456 -- which is BENIGN because legacy MaxComputeSplit also used length=-1 (the current buggy cutover diverges from legacy here too), so the fix actually improves parity. But the design must update the grep claim and add these consumers to the impact analysis instead of asserting 'only two places'. +- Test Plan does not acknowledge that the named E2E suite (regression-test/suites/external_table_p2/maxcompute/test_external_catalog_maxcompute.groovy) is an external_table_p2 suite requiring live MaxCompute/ODPS credentials, so it will be skipped in normal CI. The design frames it as 'the most direct coverage', but the only CI-runnable automated guard is the proposed UT. This should be stated explicitly so the fix is not merged believing E2E runs unattended. +- The design scopes out (correctly) the broader read-path descriptor population, but for the reviewer's checklist: the JNI scanner requires TIME_ZONE (MaxComputeJniScanner.java:139 Objects.requireNonNull on 'time_zone'), and BE max_compute_jni_reader.cpp:62-77 does NOT set time_zone in the properties map -- it must arrive via mc_desc->properties()/endpoint. Whether the cutover descriptor carries time_zone/project/quota/endpoint correctly is the separate READ-P1 blocker; this fix neither helps nor regresses it, but the split-size fix alone will NOT yield correct reads if READ-P1 is unfixed. The design states this dependency but does not call out the time_zone requirement specifically. + +**额外风险**: +- Backend-assignment determinism: FederationBackendPolicy.java:499 hashes split.getLength() into the consistent-hash placement. Changing length from 268435456 to -1 for every byte_size split changes which backend each split lands on (vs the current buggy cutover). This is invisible/benign for correctness and matches legacy, but means a before/after A-B comparison of split-to-BE placement on the SAME cutover build will differ -- worth noting so it is not mistaken for a regression during validation. +- FileQueryScanNode.java:430 accumulates totalFileSize += getLength(); with length=-1 per split this drives totalFileSize negative for byte_size scans (one -1 per split). This is a pre-existing legacy behavior (legacy also had -1) used only for stats/cost/logging, not correctness, but it propagates to profile/explain numbers and any cost-based heuristic keyed on totalFileSize. Low risk, pre-existing, but the design does not mention it. +- Other PluginDriven connectors (jdbc/es/trino/hive/hudi): the fix is strictly inside MaxComputeScanRange's byte_size branch in MaxComputeScanPlanProvider, so zero cross-connector impact is confirmed -- the design's claim holds. No additional risk here, but it is worth recording that the -1 sentinel semantics are private to the MaxCompute connector <-> MaxComputeJniScanner contract and any future generic use of ConnectorScanRange.getLength()==-1 by other code paths would need re-examination. +- No follower-replay/master sync concern: verified the change is purely in query-plan-time scan-range construction (planScan/populateRangeParams), not persisted to the edit log, so no replay/HA implications.

Step 1 says insert the new import 'between :51 InternalCatalog and :52 maxcompute.MaxComputeExternalCatalog, 按字母序'. Actual lines are 48-53 (off by two), and ASCII-case-sensitive ordering puts uppercase 'PluginDrivenExternalCatalog' (P) BEFORE lowercase sub-package imports 'hive.' / 'iceberg.' / 'maxcompute.' / 'paimon.'. Correct position is immediately after line 49 (org.apache.doris.datasource.InternalCatalog) and BEFORE line 50 (org.apache.doris.datasource.hive.HMSExternalCatalog) — i.e. grouped with the top-level datasource.* classes, not after the sub-packages. The stated placement would put it after hive/iceberg and Checkstyle CustomImportOrder would reject it. +- Line-number anchors throughout are off by two for the import region (design cites :51/:52 for InternalCatalog/MaxComputeExternalCatalog; actual is :49/:52). The method/branch anchors (paddingEngineName 896-918, MC branch 912, checkEngineWithCatalog 376-393, MC branch 390) are accurate; only the import-region anchors drift. Minor but the import-region drift directly produces the wrong-placement error above. + +**遗漏(gaps)**: +- E2E assertion is factually wrong and would FAIL even with a correct fix. The design's proposed supplementary assertion 'SHOW CREATE TABLE 输出包含 ENGINE=maxcompute' contradicts actual rendering. SHOW CREATE TABLE renders ENGINE= + table.getEngineTableTypeName() (Env.java:4283-4284), and PluginDrivenExternalTable.getEngineTableTypeName() (PluginDrivenExternalTable.java:232-233) returns TableType.MAX_COMPUTE_EXTERNAL_TABLE.name() == 'MAX_COMPUTE_EXTERNAL_TABLE'. The recorded baseline regression-test/data/.../test_max_compute_create_table.out line 3 confirms 'ENGINE=MAX_COMPUTE_EXTERNAL_TABLE', not 'ENGINE=maxcompute'. The design conflates analysis-time engineName ('maxcompute', used for DDL padding/validation) with display-time getEngineTableTypeName ('MAX_COMPUTE_EXTERNAL_TABLE'). The existing qt_test1_show_create_table already covers the regression correctly; the proposed extra assertion must be dropped. +- UT feasibility detail omitted: both paddingEngineName (line 899) and checkEngineWithCatalog (line 383) re-fetch the catalog via Env.getCurrentEnv().getCatalogMgr().getCatalog(ctlName) by NAME — they ignore any directly-constructed catalog object. The UT plan says 'construct a PluginDrivenExternalCatalog so getType()==max_compute' but never states it must be registered into CatalogMgr (or CatalogMgr mocked) for the by-name lookup to return it. As written the UT would hit the real CatalogMgr and not find the test catalog. +- CTAS path benefits but is unmentioned: validateCreateTableAsSelect (line 926) also calls paddingEngineName, so CTAS into a max_compute PluginDriven catalog is equally broken pre-fix and equally fixed. The design scopes only plain CREATE TABLE and never lists CTAS as a covered scenario or a test target, leaving a verification gap. +- No UT/E2E asserts the checkEngineWithCatalog mirror actually had a behavior change. The design claims the explicit-ENGINE consistency check is 'silently bypassed' pre-fix, but provides no failing-then-passing test that a wrong explicit ENGINE (e.g. ENGINE=hive on a max_compute catalog) is rejected only after the fix. Without it the mirror branch is untested against its WHY (violates Rule 9: the test could pass with the branch absent). + +**额外风险**: +- Root-cause analysis, central type-string mapping, and both target sites are otherwise CORRECT and verified: getType() returns lowercase 'max_compute' (CatalogFactory.java:90 toLowerCase + :100 putIfAbsent, :235-239 getType), the same key PluginDrivenExternalTable.getEngine()/getEngineTableTypeName() switch on; ENGINE_MAXCOMPUTE='maxcompute' (:125); and the warning against reusing TableType.MAX_COMPUTE_EXTERNAL_TABLE.toEngineName() is valid — that enum is NOT in the toEngineName() switch (TableIf.java) and returns null. The fix's destination is real: MaxComputeConnectorMetadata.createTable IS implemented (line 283), so padding the engine genuinely reaches a working createTable, not just a deferred failure. +- default-branch behavior for jdbc/es/trino is correctly non-regressive: pre-fix those catalogs already hit the same 'Current catalog does not support create table' throw at line 915, and ConnectorTableOps.createTable default also throws 'CREATE TABLE not supported' (line 66). So the helper's default-throw preserves their status quo — no new breakage, as claimed. +- Follower replay / master sync is NOT a concern for this fix (prompt flagged it): engine padding is analysis-time on the receiving FE; persistence uses logCreateTable edit log (PluginDrivenExternalCatalog.java:279) independent of engineName. No replay change needed. +- Batch-D ordering dependency is real and correctly flagged: P4-batchD-maxcompute-removal-design.md:100 plans to delete both instanceof MaxComputeExternalCatalog branches in CreateTableInfo; if Batch D runs without first landing the PluginDriven branch, no-ENGINE CREATE TABLE is permanently broken. The keep-set / commit-ordering note is warranted.

So the 'before' behavior described (OdpsException→RuntimeException) is not what actually happens for a missing DB on the drop path today; the improvement is real (clearer 'database' vs 'table' message) but the stated before-state is inaccurate. +- The design asserts CREATE must NOT remote-resolve the table name and cites legacy as authority. Verified correct (MaxComputeMetadataOps.java:219 passes createTableInfo.getTableName() = local literal; only db uses getRemoteName at :219). No correction to the decision itself — but note legacy createTableImpl ALSO does two FE-side existence checks (tableExist on remote db at :179 and getTableNullable at :189) that the plugin createTable override does NOT replicate and the fix does NOT add. The fix only adds the db null-check, leaving the connector to do the existence/IF-NOT-EXISTS check. This is a pre-existing divergence the fix neither closes nor flags; acceptable for scope but should be stated as an explicit non-goal rather than implied parity. + +**遗漏(gaps)**: +- EXISTING TESTS WILL BREAK, not just 'extend' — the design's test plan says 扩既有 but omits a mandatory rewrite. In /mnt/disk1/yy/.../PluginDrivenExternalCatalogDdlRoutingTest.java the stub TestablePluginCatalog.getDbNullable returns dbNullableResult which DEFAULTS TO null. After the fix, dropTable calls getDbNullable FIRST, so all 4 existing drop tests (testDropTableResolvesHandleRoutesAndUnregisters:176, testDropTableIfExistsWhenMissingIsNoop:190, testDropTableMissingWithoutIfExistsThrows:200, testDropTableWrapsConnectorException:209) will now throw 'Failed to get database' before ever reaching getTableHandle — they currently stub only getTableHandle, never getDbNullable/getTableNullable. Likewise testCreateTableInvalidatesDbCache:223 stubs only getDbForReplay, not getDbNullable, so the new createTable null-check throws DdlException and the test fails. The plan must explicitly list these 5 tests as REQUIRING rewrite (stub dbNullableResult + db.getTableNullable), otherwise the suite goes red. This is a Rule-12 'fail loud' omission. +- SHARED-OVERRIDE BLAST RADIUS understated. CatalogFactory.java:51-52 SPI_READY_TYPES = {jdbc, es, trino-connector, max_compute}. createTable/dropTable in PluginDrivenExternalCatalog are inherited by ALL FOUR, not just max_compute (verified: EsConnectorMetadata/JdbcConnectorMetadata/TrinoConnectorDorisMetadata do NOT override createTable/dropTable). The design repeatedly says '任何 full-adopter' but never names jdbc/es/trino concretely nor adds a UT proving the resolution is benign for a connector whose createTable throws 'not supported'. For DROP on jdbc/es/trino the new getDbNullable+getTableNullable adds a remote getTableNullable round-trip (ExternalDatabase.getTableNullable can hit the remote system, line 270-302) that the current code path skips — behavior end-state is still a throw so no functional regression, but the added remote call on a code path that previously short-circuited is unflagged. +- DROP path adds a getTableNullable() remote round-trip that the CURRENT plugin dropTable does not make (it goes straight to getTableHandle). This matches base ExternalCatalog.dropTable:1123 and legacy, so it is correct parity — but the design's Risk section claims '回归面小' / '逐字节一致' which is false for the unmapped case too: even WITHOUT name mapping, the fix changes the control flow (extra getDbNullable+getTableNullable resolution + potential remote validation, plus changed exception type for missing-db) for every drop on every PluginDriven catalog. The '逐字节一致' claim only holds for the SDK-bound names, not for the FE-side control flow. +- No coverage for the case where FE resolves the table exists locally but getTableHandle(remoteDb,remoteTbl) returns empty (table dropped out-of-band remotely). The existing handle-absent ifExists/throw branch (line 360-365) is preserved, but the test plan adds no case asserting it still fires AFTER the new getTableNullable resolution succeeds — i.e. a table present in FE cache but absent remotely. +- Line numbers and package paths in the design are stale/wrong (it cites fe-core/.../connector/ddl and MaxComputeMetadataOps line refs that don't all line up; actual converter is org.apache.doris.connector.ddl, CREATE override is at PluginDrivenExternalCatalog.java:263-287 with the local-dbName at :268). Cosmetic, but indicates the design was not re-derived against the current tree before writing the plan. + +**额外风险**: +- getDbNullable / getTableNullable on the master can trigger lazy metaCache build / remote round-trips (ExternalDatabase.getTableNullable Step 2-3, lines 270-302) the moment a DDL fires. If the remote (ODPS) is slow/unreachable, CREATE/DROP now blocks on metadata resolution before the SDK call, whereas the current plugin createTable path reaches the converter without that resolution. Minor latency/failure-surface change on the master write path, unmentioned. +- getRemoteDbName() on ExternalTable delegates to db.getRemoteName() (ExternalTable.java:536), and the design resolves db separately via getDbNullable then table via db.getTableNullable. There is a latent assumption that dorisTable.getRemoteDbName() (== its parent db's remoteName) equals the remoteName of the db just fetched via getDbNullable. They should be the same object, but if cache invalidation races between the getDbNullable call and getTableNullable (concurrent refresh), the two could momentarily diverge. Legacy base dropTable has the identical structure so this is not a new risk, but it is unaddressed by any concurrency note. +- The E2E plan proposes lower_case_meta_names=true on a max_compute catalog and asserts post-create visibility. But ODPS project/db naming under name-mapping is environment-specific (mixed-case real DB must already exist on the ODPS side). If the test infra's ODPS project has no mixed-case database, the E2E silently can't exercise the mapping divergence and degenerates to local==remote, giving a green test that does NOT prove the fix (Rule 9 violation). The plan does not specify how the mixed-case remote object is provisioned, so the E2E may not actually fail pre-fix. +- Per Rule 9, the proposed UT 'testCreateTableUsesRemoteDbName' must use a real CreateTableInfoToConnectorRequestConverter (or assert on the dbName actually passed) — but the existing test mocks the converter statically (MockedStatic at line 227). If the new UT keeps mocking the converter, verify(metadata).createTable(argThat(req -> req.getDbName().equals('DB1'))) cannot work because the mocked converter returns a stub req unaffected by the dbName argument. The UT must capture the SECOND argument passed to convert() (the dbName) via the static-mock invocation, not the resulting request's getDbName(). The test-plan wording 'argThat(req -> req.getDbName()...)' is unimplementable against the existing mocking style and would either not compile against intent or pass vacuously. + +--- + +### 阶段 3 — 恢复分区可见 (partitions TVF / SHOW PARTITIONS) + +### FIX-PART-GATES — partitions() TVF + SHOW PARTITIONS analyze 网关 + 分区元数据 override + +**Scope**: review 发现 DDL-C1 / CACHE-C1 / CACHE-C2(severity major,regression=yes,对抗存活 3✓/0✗ ×3),含 ⚠️ Batch-D 红线。本 section 只设计、不写码。 + +#### Problem +翻闸(cutover)后 MaxCompute catalog 变成 `PluginDrivenExternalCatalog`、其表是 `PLUGIN_EXTERNAL_TABLE`。对一张真实分区的 MC 表执行两条用户命令在 FE **analyze 阶段直接抛错**,legacy 可用、翻闸即坏: +- `SELECT * FROM partitions('catalog'='mc','database'='d','table'='t')` → 抛 `AnalysisException("Catalog of type 'max_compute' is not allowed in ShowPartitionsStmt")`(若补了 catalog 网关,下一步又因表类型不在 allow-list 抛 `MetaNotFound`)。 +- `SHOW PARTITIONS FROM ` → 抛 `Table X is not a partitioned table`。 + +触发条件:翻闸后(`SPI_READY_TYPES` 含 max_compute、CatalogFactory 走 PluginDriven)对任意真实分区的 MC 表跑上述两命令。两条命令的 BE 取数支路 / dispatch / handler 都已由 T06c 接好,但因 analyze 网关挡在前面,这些 handler 是**不可达死代码**(`MetadataGenerator.dealPluginDrivenCatalog`、`ShowPartitionsCommand.handleShowPluginDrivenTablePartitions`)。 + +#### Root Cause +三个独立缺口,均为 T06c "FE 分发接线" 漏接 analyze 网关: + +1. **DDL-C1 / CACHE-C1(partitions() TVF 双重网关)** — `fe/fe-core/.../tablefunction/PartitionsTableValuedFunction.java:172-176` 的 catalog allow-list 只认 `internal / HMSExternalCatalog / MaxComputeExternalCatalog`,无 `PluginDrivenExternalCatalog`;`:184-185` 的 `getTableOrMetaException(...)` 允许类型只到 `OLAP/HMS_EXTERNAL_TABLE/MAX_COMPUTE_EXTERNAL_TABLE`,无 `PLUGIN_EXTERNAL_TABLE`。构造器 `:149` 即 eager `analyze()`,故双重挡死。已接好的 BE handler `MetadataGenerator.java:1317-1318`(dispatch)+`:1359-1377`(`dealPluginDrivenCatalog`,走 SPI + remote 名解析)永不可达。 + -

The 'equivalent: !getPartitionColumns().isEmpty()' phrasing for isPartitionedTable() is circular if getPartitionColumns itself depends on the prop. Correct the design to specify the exact prop-sourcing mechanism (re-fetch vs. cache-subclass). +- The Batch-D red-line (part D) is correct AND the existing Batch-D doc is factually wrong as the design states: the amendment at P4-batchD-maxcompute-removal-design.md:70-77 asserts 'P4-T06c adds a PluginDrivenExternalCatalog branch' for PartitionsTableValuedFunction — verified FALSE (the file contains no PluginDrivenExternalCatalog reference at all). The design's instruction to reword 'T06c adds' -> 'FIX-PART-GATES adds' and to gate the :173 MC-branch deletion behind this fix is a valid and necessary correction. No error here; this part is sound. + +**遗漏(gaps)**: +- PROP-SOURCING (load-bearing, unaddressed): The design's getPartitionColumns()/isPartitionedTable() both depend on the connector's `partition_columns` prop, but that prop is NOT persisted anywhere reachable at call time. Verified: PluginDrivenExternalTable.initSchema():108 stores `new SchemaCacheValue(columns)` (base class), and base SchemaCacheValue.java only holds `List schema` (no properties field). There is NO PluginDriven SchemaCacheValue subclass (grep confirms only Iceberg/Paimon/HMS/MaxCompute subclasses exist). ConnectorColumnConverter.convertColumn():67 drops all partition-key markers (it only carries isKey, and MaxComputeConnectorMetadata:141-146 builds partition ConnectorColumns with isKey=false). Therefore the design's stated 'minimal impl: filter getFullSchema() by the prop's name set' is impossible as written — getFullSchema() returns only Columns with no way to identify partition columns, and the prop is not in the cache. The override MUST either (a) re-call metadata.getTableSchema() via the connector SPI on every isPartitionedTable()/getPartitionColumns() call (a remote ODPS metadata round-trip), or (b) introduce a PluginDrivenSchemaCacheValue subclass that persists partition_columns and have initSchema() populate it. The design picks neither and the two design bullets contradict (one says 'read getTableSchema-exposed prop' = re-fetch; the other says 'filter getFullSchema()' = impossible). This must be resolved before implementation. +- PERF/BEHAVIOR DEVIATION not flagged: if the chosen sourcing is per-call getTableSchema() re-fetch (the only option without a new cache subclass), then isPartitionedTable() — called inside ShowPartitionsCommand.validate() at :264 and potentially in planner partition paths — issues a live remote metadata fetch each time, whereas legacy MaxComputeExternalTable.getPartitionColumns():92-97 reads from the cached MaxComputeSchemaCacheValue. Design does not register this as a deviation. +- TEST INFEASIBILITY for the proposed UT not acknowledged: the new 'assert isPartitionedTable()==true' test on PluginDrivenExternalTable requires stubbing the connector's getTableSchema() to return the partition_columns prop AND ensuring the schema-cache/init path is reachable (the existing PluginDrivenExternalTableEngineTest helper never triggers initSchema(); it only exercises getEngine/getEngineTableTypeName which don't touch schema). The test plan doesn't state how the prop is fed to the table under test, which is non-trivial given the prop is not cached. +- COLUMN-NAME MAPPING mismatch for the generalized claim: initSchema():98-105 remaps column names via metadata.fromRemoteColumnName() (e.g., JDBC lowercases), but MaxComputeConnectorMetadata writes the RAW remote partition names into the `partition_columns` prop at :140 BEFORE any mapping. So 'filter getFullSchema() (mapped names) by prop names (raw names)' breaks for any connector that remaps identifiers. MC itself does NOT override fromRemoteColumnName (verified — default returns name unchanged), so MC works today, but the design's central 'keyed on connector, any full-adopter reuses' claim is unsound for remapping connectors and must be either narrowed or fixed by mapping the prop names through fromRemoteColumnName. +- partition_values() TVF gate not mentioned: PartitionValuesTableValuedFunction.java:114-115 has the identical missing-PluginDriven catalog gate and :127 lacks PLUGIN_EXTERNAL_TABLE, and Batch-D's delete list includes its MC branch (~:115). The design scopes out partition_values entirely. This is DEFENSIBLE (verified :132-134 only ever supported HMS tables — 'Currently only support hive table's partition values meta table' — so MC tables always hit that throw even in legacy, meaning no regression and no Batch-D red-line equivalent), but the design should explicitly note it distinguished this case rather than silently omitting a file in the same Batch-D delete list. + +**额外风险**: +- Ordering fragility beyond Batch-D: getPartitionColumns() correctness relies on the prop's comma-separated order matching the schema-append order. Verified this holds today (MaxComputeConnectorMetadata:137-147 builds partitionColumnNames and appends columns in the same loop; legacy MaxComputeExternalTable.initSchema:181-197 appends in odpsTable partition-column order). But if a connector ever builds the prop and the column list in different orders, getPartitionColumns() would silently misorder — there's no invariant enforcing this. Worth a guard/assert or a doc note in the SPI contract for partition_columns. +- isPartitionedTable() is a TableIf default returning false and is consumed in more places than SHOW PARTITIONS (planner, DESCRIBE, partition-prune entry checks). Flipping it to true for MC PluginDriven tables WITHOUT also overriding supportInternalPartitionPruned()/getNameToPartitionItems() (which the design explicitly defers) can produce an inconsistent state: a table that reports isPartitionedTable()==true but supportInternalPartitionPruned()==false and getNameToPartitionItems()=={} (the ExternalTable defaults at :458/:478). Verified ExternalTable.initSchemaAndPartitionPrune-style logic uses these together (PartitionValuesTableValuedFunction/ExternalTable:440-446 gate on supportInternalPartitionPruned + getPartitionColumns + getNameToPartitionItems). The design registers the pruning loss as a known degradation, but should also verify no code path assumes isPartitionedTable()==true IMPLIES non-empty getNameToPartitionItems(), which could NPE/empty-prune-to-full-scan inconsistently rather than cleanly. +- follower/replay and gsonPostProcess: PluginDrivenExternalTable.gsonPostProcess():157-165 only fixes table type; the new overrides read live connector schema, so on a follower FE (or after replay) the first isPartitionedTable() triggers connector init. If the connector/session isn't ready on a follower at validate() time this could throw where legacy (cache-backed) did not. Not analyzed by the design; worth confirming follower behavior for the re-fetch path. +- The new 'non-partitioned guard' in PartitionsTableValuedFunction (design B: `else if (table instanceof PluginDrivenExternalTable && !table.isPartitionedTable())`) will, under per-call re-fetch sourcing, perform a remote getTableSchema() during TVF analyze for every partitions() call on a PluginDriven table — including non-MC connectors that declared no partition_columns (they'll re-fetch, get empty, and throw 'not a partitioned table'). Behavior is correct but adds a remote call to the analyze hot path that legacy MC avoided (legacy used cached getOdpsTable().getPartitions()). + +--- + +### 阶段 4 — 写回正确性 (affected rows) + +### FIX-WRITE-ROWS — INSERT affected rows 恒 0 — doBeforeCommit 补 loadedRows=getUpdateCnt() + +- **Problem**: 翻闸(SPI 事务模型,当前唯一 adopter = MaxCompute)后,对 PluginDriven 外表执行 `INSERT INTO ...` 数据被正确写入,但客户端返回 / `SHOW INSERT RESULT` / `fe.audit.log` 的 returnRows 恒为 `affected rows: 0`。触发条件:catalog 走 SPI 事务模型(`writeOps.usesConnectorTransaction()==true`,即 `connectorTx != null`)的任意 INSERT。JDBC / auto-commit handle 模型(`connectorTx==null`)不受影响。属可观察输出回归(数据不丢,但行数判读错误,影响用户、审计、上层工具)。 + +- **Root Cause**: 精确定位 + - `fe/fe-core/src/main/java/org/apache/doris/nereids/trees/plans/commands/insert/PluginDrivenInsertExecutor.java:146-150` —— `doBeforeCommit()` 只在 `insertHandle != null` 时调 `writeOps.finishInsert(...)`。事务模型下 `insertHandle` 恒为 null(handle 仅在 `beforeExec()` 的 JDBC 分支创建,而事务模型在 `:109-113` 早退),整段被跳过,`loadedRows` 永不赋值。 + - `loadedRows` 字段定义于 `AbstractInsertExecutor.java:69`(`protected long loadedRows = 0;`)。事务模型下,BE 的 MaxCompute sink 只通过 `TMCCommitData.row_count` 上报行数,从不更新 `num_rows_load_success`(DPP_NORMAL_ALL),故 `AbstractInsertExecutor.java:221-222` 取回 0,`loadedRows` 停在默认 0。 + - 下游 `BaseExternalTableInsertExecutor.java:197/201/203` 用 `loadedRows` 设 `setOk` / `setOrUpdateInsertResult` / `updateReturnRows` → 全部为 0。 + - legacy 基线 `MCInsertExecutor.java:74-78`:`doBeforeCommit()` 在 `finishInsert()` 之外还有 load-bearing 的一行 `loadedRows = transaction.getUpdateCnt();`。翻闸 restructure 只镜像了 `finishInsert` 的等价物(`connectorTx.commit` 经 txn manager),漏镜像 `loadedRows` 赋值。 + - 历史误判:`plan-doc/tasks/designs/P4-T05-T06-cutover-design.md:114`(W-c / gap G2)称 `doBeforeCommit ... → null for MC ⇒ correctly skipped`,把"跳过 doBeforeCommit"当作正确——本设计显式推翻该结论(见 Risk)。 + +- **Design**: 在 `PluginDrivenInsertExecutor.doBeforeCommit()` 的事务模型分支回填 `loadedRows`,镜像 legacy 可观察行为。 + - 不扩展任何 SPI:`getUpdateCnt()` 全链路已实现且仅差调用方 —— `ConnectorTransaction.getUpdateCnt()`(default,`fe-connector-api/.../ConnectorTransaction.java:96`)→ `MaxComputeConnectorTransaction.getUpdateCnt()`(`fe-connector-maxcompute/.../MaxComputeConnectorTransaction.java:158-160`,= `sum(TMCCommitData.getRowCount())`)→ 经 `PluginDrivenTransaction.getUpdateCnt()`(`PluginDrivenTransactionManager.java:183-184`)暴露 → `Transaction.getUpdateCnt()`(`Transaction.java:65` default)。`transactionManager.getTransaction(long)` 已声明 `throws UserException`(`TransactionManager.java:30`),与 `doBeforeCommit()` 现有签名 `throws UserException` 兼容。 + - 通用插件层修法,keyed on `connectorTx != null`(SPI 事务模型),非 hardcode maxcompute —— 任何未来事务模型 connector 自动受益;`connectorTx == null` 的 JDBC/auto-commit 路径保持原状(沿用 coordinator/DPP_NORMAL_ALL 取到的 `loadedRows`,与 legacy JdbcInsertExecutor 一致,不回填)。 + - 镜像 legacy 的 mirror 方式:legacy 用 `(MCTransaction) transactionManager.getTransaction(txnId)` 取 txn 再 `getUpdateCnt()`;翻闸已持有 `connectorTx` 字段且 `txnId == connectorTx.getTransactionId()`。两种等价取法:(a) 直接 `connectorTx.getUpdateCnt()`(`connectorTx` 是 executor 现有字段,最少耦合,无需 throws/lookup);(b) `transactionManager.getTransaction(txnId).getUpdateCnt()`(与 legacy 取法逐字一致,但引入 `throws UserException` 的 lookup)。推荐 (a):`connectorTx` 已在手、语义等价、不引入可失败的 manager lookup,改动最小;最终值与 legacy 一致(同一 `TMCCommitData.row_count` 累加链)。 + - 现有 `if (writeOps != null && insertHandle != null)` 的 `finishInsert` 分支不动(JDBC handle 模型仍需);新增逻辑作为事务模型独立分支。 + +- **Implementation Plan**: 逐文件逐方法 + - [fe-core] `fe/fe-core/.../insert/PluginDrivenInsertExecutor.java` `doBeforeCommit()`(:146-150):在现有 `finishInsert` guard 之外,新增事务模型回填分支 —— `if (connectorTx != null) { loadedRows = connectorTx.getUpdateCnt();

Verified the ORDER in legacy MCInsertExecutor.java:75-78 is: getTransaction -> `loadedRows = transaction.getUpdateCnt()` (line 76) THEN `transaction.finishInsert()` (line 77). i.e. legacy reads the count BEFORE finishInsert commits. The fix's recommended approach (a) reads `connectorTx.getUpdateCnt()` in doBeforeCommit BEFORE PluginDrivenTransactionManager.commit() (called later in onComplete:105). Order is preserved — but note getUpdateCnt() reads commitDataList which is independent of commit(), so order is immaterial here; the design's 'order 无关' claim is correct. No behavioral error, just confirming the mirror is faithful. +- The design says approach (b) `transactionManager.getTransaction(txnId).getUpdateCnt()` is 'with legacy 取法逐字一致'. Not quite literal: legacy casts to `(MCTransaction)` and calls the concrete getUpdateCnt; the SPI path returns a `PluginDrivenTransaction` whose getUpdateCnt delegates to connectorTx (PluginDrivenTransactionManager.java:183-184). Semantically equivalent, but (b) is NOT a byte-for-byte mirror. This does not affect the recommendation — (a) is the right choice and the design picks it — but the '逐字一致' characterization of (b) is slightly overstated. + +**遗漏(gaps)**: +- E2E affected-rows capture shape unverified. The design proposes `def res = sql "INSERT ..."; assertEquals(3, res[0][0])`, but no existing external-table write suite (hive/iceberg/mc) uses this pattern — they all verify via `order_qt_*` on a follow-up SELECT. Whether the Doris regression `sql` helper returns INSERT affected-rows as `res[0][0]` (vs. needing `SHOW INSERT RESULT` / a JDBC updateCount path) is unconfirmed in-repo; implementation should pin the exact accessor before claiming the E2E asserts the regression. This is a test-mechanics gap, not a design flaw. +- Multi-statement / multi-fragment accumulation not explicitly covered by the proposed UT. The real value comes from summing N `TMCCommitData.row_count` fed by multiple BE fragment reports; the proposed StubConnectorTransaction returns a single fixed N, so it does not exercise the `commitDataList.stream().sum()` accumulation path (that lives in MaxComputeConnectorTransaction, in fe-connector-maxcompute, which the fe-core UT cannot reach). E2E Test 4 (multi-batch, 3 separate INSERTs of 1 row each) is the only place real accumulation across the feed path is exercised, and the design only proposes asserting Test 1/Test 2 — adding an affected-rows assertion to Test 4 would close this. +- Design does not state whether `filteredRows` should also be backfilled. It correctly mirrors legacy MCInsertExecutor (which only sets loadedRows), and MC never populates DPP_ABNORMAL_ALL so filteredRows legitimately stays 0 — but the design should explicitly note this as an intentional non-change for completeness, since `afterExec`/`setOk` also report a filtered count. +- No mention of the empty-insert path. Verified independently it is safe (empty insert skips executeSingleInsert entirely, so doBeforeCommit never runs and loadedRows=0 is correct), but the design's risk section should have named it since `beginTransaction`/`connectorTx` are skipped there. + +**额外风险**: +- Strict-mode interaction is benign but undocumented. AbstractInsertExecutor.checkStrictModeAndFilterRatio (line 232-246) runs in executeSingleInsert BEFORE onComplete->doBeforeCommit, so it evaluates with loadedRows still 0. For MC this is harmless (filteredRows=0 too, so the ratio guard `filteredRows > ratio*(filteredRows+loadedRows)` is `0 > 0` = false). The backfill happening afterward cannot retroactively affect the strict-mode check — which matches legacy exactly. Worth a one-line note in the design so a future reader doesn't 'fix' the ordering and accidentally make the filter-ratio denominator non-zero. +- getUpdateCnt() is read off connectorTx without holding the synchronized lock that addCommitData/commit use (MaxComputeConnectorTransaction.addCommitData synchronizes on `this`, but getUpdateCnt streams commitDataList unsynchronized). At doBeforeCommit time all BE fragment reports have completed (coordinator.join returned) so no concurrent addCommitData is in flight — same as legacy MCTransaction.getUpdateCnt which is also unsynchronized. Low risk, but it relies on the join->doBeforeCommit happens-before edge; if a future change moves commit-data feed off the join path this read could race. Pre-existing in legacy, not introduced by this fix. +- If a future SPI transaction-model connector returns a stateful ConnectorTransaction but does NOT override getUpdateCnt(), the backfill will silently write 0 (SPI default returns 0) — re-introducing the exact symptom for that connector with no fail-loud. The fix is generic and correct for MC, but the 'any future transaction-model connector automatically benefits' claim is conditional on that connector implementing getUpdateCnt(). Worth flagging in the connector-author contract / SPI javadoc rather than relying on the default. +- The design proposes a doc correction to P4-T05-T06-cutover-design.md:114 and decisions-log but scopes it out of the code commit. Confirmed line 114 does say 'doBeforeCommit ... null for MC => correctly skipped' and is genuinely wrong about loadedRows.

合并行数）、谓词转换（`convertPredicate:189`）、per-split thrift（`setPaimonParams:253`）、`getPaimonSplitFromAPI:581`（真 SDK 调

分支——非 DataSplit 强制 JNI、`shouldForceJniForSystemTable`（binlog/audit_log，`:523-536`）、`getProcessedTable` 拒 scan-params/time-travel（`:883-890`）。 +- **关键迁移约束**：迁后 sys wrapper **必须 extends

`getOrFetchSnapshotCacheValue:383` 复用同 pin。`StatementContext.loadSnapshots:987` 按 `MvccTableInfo` 存不透明 `MvccSnapshot`。 +- **SPI 拆分难点**：`ConnectorMvccSnapshot`（final）只能载 snapshotId/timestamp，**载不动**分区 map + Table handle → 富 pin 须留 fe-core 侧。MTMV 类型（`PartitionItem`/`PartitionType`/`Column`/`MTMVSnapshotIf` 及其 GSON 子类）**无 SPI 等价物** → MTMV 必须留在 fe-core。 +- **好消息**：表级 staleness=snapshotId 正好映 `ConnectorMvccSnapshot.getSnapshotId():51`（long，-1 哨兵对齐 `PaimonSnapshot.java:23`）；分区级 staleness=`ConnectorPartitionInfo.getLastModifiedMillis():90`（**已存在**，firsthand 核实，6-arg ctor

Real gaps with NO automated parity coverage + +These are the holes the regression suites in §2 do **not** close. They are the substance of +the cutover risk and must be addressed by new UTs and/or the live-e2e hard gate. + +### 3.1 Connector-path predicate-conversion UT (❌ no coverage) +`fe-connector-paimon` has `PaimonPredicateConverter` but **no unit test** for it — contrast +`fe-connector-trino/.../TrinoPredicateConverterTest.java` and +`fe-connector-maxcompute/.../MaxComputePredicateConverterTest.java`, which both exist. Note the +**legacy** converter (`datasource.paimon.source.PaimonPredicateConverter`) *does* have a direct +fe-core unit test (`fe/fe-core/src/test/java/org/apache/doris/planner/PaimonPredicateConverterTest.java`) +on top of the `test_paimon_predict` row checks; the gap is specifically that the **connector** +converter (`ConnectorExpression` → `org.apache.paimon.predicate.Predicate`) has no +direct test. **Recommended:** a connector-side `PaimonPredicateConverterTest` (offline, +no fe-core import) covering each op (eq/ne/lt/le/gt/ge/in/isNull/and/or) + the datetime/TZ +literal-format edge (the source-TZ session gotcha that bit maxcompute — see MEMORY +"连接器 session TZ"). This is the highest-value missing UT. + +### 3.2 Native-reader + deletion-vector connector parity (⚠️ partial) +The native ORC/Parquet path and deletion-vector merge are exercised on the **legacy** split +classifier (`test_paimon_cpp_reader`, `test_paimon_deletion_vector`). After cutover the +classification + deletion-file plumbing run through the **connector** `PaimonScanPlanProvider` +(`buildJniScanRange` / `RawFile` / `DeletionFile` handling, ~`PaimonScanPlanProvider.java`). +There is no assertion that the connector emits the same native-vs-JNI split decision or the +same deletion-file list. The before/after run (§4) covers row correctness, but a focused +**connector split-classification UT** would localize a regression instead of surfacing it as +a wrong row count three suites away. + +### 3.3 Sys-table forced-JNI override (⚠️ partial) +`$binlog` / `$audit_log` (and other non-data sys-tables) must be **forced to the JNI reader** +even when native is otherwise preferred. `paimon_data_system_table` exercises the queries but +nothing asserts the *forced-JNI override decision itself* on the connector path. After cutover +this override lives in the connector; a regression here would silently route a sys-table to a +native reader that cannot read it. Needs an explicit connector-side assertion (or a +before/after explain diff on `$binlog`). + +### 3.4 Live-e2e hard gate (CI skips — env-gated) +The flavor suites for **HMS / DLF / DLF-REST / S3 / OSS / MinIO / GCS** (§2 row 15) require +real remote catalogs/credentials and are **skipped in CI**. The connector's per-flavor +catalog assembly (`PaimonConnector.createCatalog` switch + per-flavor +`ExecutionAuthenticator`, P5-T03) is therefore **not** validated by CI at all. This is the +single biggest before/after risk and must be a **user-run live-e2e hard gate** before +cutover (consistent with `tasks/P5-paimon-migration.md` §翻闸前置硬门 ①). + +--- + +## 4. Live-e2e run plan (user-run, pre-cutover hard gate) + +CI proves only the offline + filesystem/JDBC slice. The live gate proves the env-gated +flavors and the full read path against a real paimon deployment. Run this **twice** — once on +`master` (legacy) and once on the cutover branch (paimon in `SPI_READY_TYPES`) — and diff the +`.out` files. Identical output = parity. + +1. **Per-flavor connectivity + read** (one warehouse per flavor): + - filesystem (local/HDFS), HMS, DLF, DLF-REST, JDBC, plus S3/OSS/MinIO/GCS storage. + - For each: `SHOW DATABASES`, `SHOW TABLES`, `SELECT *` (no predicate), one predicate + query, one partition-pruned query → diff vs legacy. +2. **Read-path matrix on at least one keyed+partitioned table per flavor:** + predicate pushdown, partition pruning, runtime-filter pruning, COUNT pushdown, + deletion-vector (orc+parquet), native vs `set force_jni_scanner=true`, incremental read, + time-travel (snapshot-id + tag), `$snapshots/$files/$binlog/$audit_log`, session-TZ + datetime predicate. +3. **MTMV staleness:** create an MV over a paimon source, mutate the source, confirm the MV + detects staleness via the snapshot-pin key (P5-T25 invariant) → diff vs legacy. +4. **Gate criterion:** every diff empty. Any non-empty diff blocks cutover (B7). + +The offline FE→BE round-trip smoke (`PaimonTableSerdeRoundTripTest`, this task) is the CI-side +companion to step 2's serialization — it catches version-drift / non-serializable / base64 +breaks that step 2 would otherwise only surface as a runtime BE failure. + +--- + +## 5. What this task (T02) delivers vs what remains + +- **Delivered (T02):** this parity-baseline doc; the offline FE→BE serialized-`Table` + round-trip smoke (CI, not env-gated); the R-007 3-way `paimon.version` pin comment in + `fe/pom.xml`. +- **Remaining (other tasks):** the connector `PaimonPredicateConverterTest` (§3.1), the + connector split-classification / deletion-vector / forced-JNI assertions (§3.2–3.3), the + MTMV snapshot-pin UT (P5-T25), and the user-run live-e2e hard gate (§4).

B4: sys-tables (E7) + MVCC (E5) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Port paimon system tables and MVCC snapshots onto the plugin connector SPI. - T16: greenfield E7 SPI on ConnectorTableOps — listSupportedSysTables + getSysTableHandle (default no-ops; MC/jdbc/es/trino unaffected). - T17: PaimonConnectorMetadata implements E7 — names from SystemTableLoader.SYSTEM_TABLES; sys table loaded via the existing getTable seam with a 4-arg Identifier(db,table,"main",sysName); sys handle carries sysTableName + forceJni (binlog/audit_log); shared PaimonTableResolver gives metadata + scan one sys-aware reload rule. - T18: generic fe-core glue — PluginDrivenExternalTable centralizes handle acquisition into resolveConnectorTableHandle and delegates getSupportedSysTables to the connector; new PluginDrivenSysExternalTable (reports PLUGIN_EXTERNAL_TABLE) + PluginDrivenSysTable reuse the live SysTableResolver/NativeSysTable machinery (reusable by future connectors). - T19: forceJni gate so binlog/audit_log go JNI not native; buildTableDescriptor -> HIVE_TABLE (also fixes a latent normal-table SCHEMA_TABLE descriptor gap, DV-024); PluginDrivenScanNode fail-loud guard rejects scan-params/time-travel on system tables. - T20: first E5 MVCC consumer — beginQuerySnapshot/getSnapshotAt/getSnapshotById (empty table -> -1; sys handle -> empty) + SUPPORTS_MVCC_SNAPSHOT/TIME_TRAVEL capabilities. Inert until B5 wires the fe-core MvccTable consumer. Decisions: D-039 (E7 reuses the live SysTable machinery; RFC §10's $-suffix-via-getTableHandle design was never implemented and is superseded, DV-023). Deviations: DV-023, DV-024. Verification: import-gate 0; connector 124 tests pass (1 live skipped); fe-core PluginDriven*Test 100 pass; checkstyle 0; no cutover/B5 leakage (paimon not in SPI_READY_TYPES; PluginDrivenExternalTable still not an MvccTable).

The class is + * source-agnostic: it is constructed directly here against a mocked connector.

From: morningman Date: Thu, 11 Jun 2026 11:06:01 +0800 Subject: [PATCH 014/128] [P5-B7+fixes] (connector+fe-core) P5 paimon B7 cutover + 8 fullpath-review fixes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Combines all previously-uncommitted P5 paimon work into one commit (per request). 8 fullpath-review fixes (BLOCKERs + key MAJORs) — connector + SPI + fe-core bridge: - FIX-STORAGE-CREDS: applyStorageConfig translates canonical s3.*/oss.*/AWS_* -> fs.s3a./fs.oss. (+DLF region->OSS endpoint) - FIX-NATIVE-PARTVAL: per-type serializePartitionValue + session TZ (LTZ only); binary/varbinary drops the partition map (no [B@hash garbage) - FIX-TZ-ALIAS: full legacy ZoneId.SHORT_IDS + 4 Doris overrides alias map (CST/PST/EST now resolve for FOR TIME AS OF datetime strings) - FIX-TABLE-STATS: getTableStatistics override + PaimonCatalogOps.rowCount seam (normal AND system tables, via the sys-aware resolveTable) - FIX-CPP-READER: honor enable_paimon_cpp_reader -> native DataSplit.serialize so BE's PaimonCppReader can decode the split - FIX-READ-NOTNULL: mapFields forces read-path columns nullable (legacy parity) - FIX-HMS-CONFRES: new ConnectorContext.loadHiveConfResources hook + 2-arg buildHmsHiveConf file-base merge (external hive-site.xml reaches the metastore) - FIX-REST-VENDED: new ConnectorContext.vendStorageCredentials hook + scan-props vended AWS_* overlay (REST per-table tokens reach BE) Also carries the previously-uncommitted B7 core cutover + D-045/D-046 restores. Tests: fe-connector-paimon 213 pass / 0 fail / 1 skip (live-gated); fe-core compiles + DefaultConnectorContextVendTest 2/0. Each fix's root-cause/patch/UT and impl-time corrections are in plan-doc/tasks/designs/P5-fix--design.md. Excluded from this commit: regression-test/conf/regression-conf.groovy (plaintext Aliyun keys, pending scrub) and scratch dirs (.audit-scratch/, conf.cmy/, META-INF/, *.bak).

design 尾 + 已修，复审锚点） +- **FIX-STORAGE-CREDS**：设计的 anon-bucket 测断言 `assertNull(fs.s3a.aws.credentials.provider)` 错——Hadoop `Configuration` 有 baked-in 默认 provider 链；改 `assertNotEquals(Simple-single,…)`（产线正确，仅测断言订正）。 +- **FIX-NATIVE-PARTVAL**：`ISO_LOCAL_DATE_TIME` 在秒+纳秒皆 0 时**省略秒**（`08:00:00`→`"…T08:00"`，legacy 同行为）；测用非零秒 wall clock（`01:02:03`）避歧义。 +- **FIX-TZ-ALIAS**：把 `resolveTimestampDigitalUnaffectedByUnsupportedZoneAlias` 的 `"CST"`→`"XYZ"`（CST 修后会解析，留 CST 则测失去捕变力）——设计说"keep as-is"，此为 Rule 9 必要订正。 +- **FIX-HMS-CONFRES**：设计 test2 用 `hive.metastore.uris`，被 `HMS_URI` 别名二次解析干扰；改用非 uri 键 `hive.metastore.sasl.qop` 隔离 file-base-vs-user 优先级（产线正确）。 +- **FIX-REST-VENDED**：设计"Construction change"（线程 `Supplier` 入 ctor + 改 `PluginDrivenExternalCatalog`/`CatalogFactory`）**实际不需要**——impl 仅用 `rawVendedCredentials` 入参，故 0 ctor 改、0 `PluginDrivenExternalCatalog` 改（blast-radius 更小）。 -1. **D-039（签字）— E7 形状 = 复用 live SysTable 机制（非 RFC §10）**：RFC §10 的「`$`-后缀普通表 + 连接器 `getTableHandle` 内解析 + `listSysTableSuffixes`」**从未落地**；live fe-core 用 `SysTableResolver`+`NativeSysTable`+`TableIf.getSupportedSysTables/findSysTable`（iceberg+legacy-paimon 共用）。用户签复用该机制。RFC §10 已加 superseded 脚注（[DV-023]）。 -2. **T20 MVCC inert until B5（签字留 B4）**：E5 SPI

不达用户（安全）。 -3. **final review BLOCKER（已修）**：`PluginDrivenScanNode.create` 原直调 `metadata.getTableHandle(remoteName)` **绕过** T18 的 `resolveConnectorTableHandle` seam → sys 表得普通 handle（forceJni=false）→ binlog/audit_log DataSplit 走 native **静默错行**（inert today，翻闸后 live）。修 = `create` 改走 `table.resolveConnectorTableHandle(session, metadata)`（普通表字节等价、sys 表得 sys handle），TDD red→green。**教训**：scan node 有独立 handle 获取面，T18 集中 seam 时漏了它——下轮改 fe-core handle 流时须 grep 全 `metadata.getTableHandle(` 调用方。 -4. **DV-024（B2 遗留缺陷，B4 顺修）**：连接器无 `buildTableDescriptor` override → 普通 paimon plugin 表 toThrift 走 SCHEMA_TABLE fallback（BE `descriptors.cpp:635` SchemaTableDescriptor），legacy+sys 须 HIVE_TABLE（`:644`）。T19 一处 override 同修普通+sys。 +--- -## 🎯 下一 session = B5（MTMV 桥；gated on B4 全完，现满足） +# ▶️ 下一步 —

PluginDrivenExternalTable` implements `MTMVRelatedTableIf`+`MTMVBaseTableIf`+`MvccTable`；`loadSnapshot`（`beginQuerySnapshot` 定 snapshotId + at-snapshot 物化分区集**一次**）。**这是 E5 接活点**：须调 `connector.getMetadata().beginQuerySnapshot` + 构造 `ConnectorMvccSnapshotAdapter`（现零构造方）；并把 scan-params/time-travel 接到 `PluginDrivenScanNode`（接活后 T19 sys-table fail-loud guard 才生效，否则现 dormant）。 --

preload。 +- **failureScenario**: 此前预载 latest snapshot + partition view(锁获取前)的 paimon 查询/MTMV plan 现规划时惰性载。仅规划延迟/preload-warmup 回退;MVCC pin 仍经 StatementContext.loadSnapshots 在正常规划创建,故查询和 MTMV-refresh 结果不受影响。 +- **suggestion**: 若 paimon preload parity 重要则 override supportsLatestSnapshotPreload()=true(并考虑 supportsExternalMetadataPreload),或 gate on connector capability;否则 document intentional preload reduction。 + +--- + +### 路径 12. mvcc + +覆盖说明:MVCC snapshot-isolation 路径两侧端到端追踪。关键结果(flagged risk):查询起始钉的 snapshot 确实到达 split planning — 三个 scan-side handle-consumption 站点(getSplits:554、startSplit:694、getOrLoadPropertiesResult:877)在消费 currentHandle 前调 pinMvccSnapshot,resolveScanTable 的 Table.copy(scan.snapshot-id) override scan-time reload 默认值,故 split planning 从不静默 re-resolve "latest"。batch 路径也被钉。empty-table/no-handle 正确降级 snapshotId -1 不发 scan.snapshot-id=-1。time-travel、MTMV、isPartitionInvalid、@incr null-reset 剥离全 faithful 移植。 + +#### Finding 12.1 — B5a query-begin pin 不像 legacy 那样冻结 schema 版本(schemaId),故并发中途 schema evolution 可读 latest schema 而非 query-begin schema + +- **Severity**: MINOR +- **New**: `PluginDrivenMvccExternalTable.java:348-357`(getSchemaCacheValue)和 201-202(loadSnapshot B5a 路径返回 pinnedSchema==null) +- **Legacy**: `PaimonExternalTable.java:374-376`(getSchemaCacheValue)→ 378-381 getPaimonSchemaCacheValue → PaimonUtils.getSchemaCacheValue 在 snapshotValue.getSnapshot().getSchemaId() 解析;`metacache/paimon/PaimonLatestSnapshotProjectionLoader.java:79-81` 在 query-begin 捕获 latestSchemaId +- **Difference**: 对普通(非 time-travel)query-begin pin,legacy 在 loadSnapshot 时将 latest schemaId 存入钉的 PaimonSnapshot,每个 getSchemaCacheValue/getFullSchema 在该冻结 schemaId 读 schema(cache keyed by (nameMapping, schemaId))。新 B5a pin 设 pinnedSchema=null(仅显式 time-travel 设 pinned schema),故 getSchemaCacheValue fallback 到 getLatestSchemaCacheValue() 读当前 latest schema(仅 nameMapping keyed,无 schemaId)。connectorSnapshot 确携 schemaId 但 B5a 路径从不查询。 +- **failureScenario**: 查询在 paimon 表 schema v5 起始;statement 仍 analyzing/planning 时并发 writer commit schema 变更到 v6 且 FE schema metacache 该表条目被刷新。Legacy 全查询继续在钉的 schemaId v5 解析列;新路径对 getFullSchema/getPartitionColumns 解析现-latest v6 schema 而数据仍在钉的 snapshot id 读,故列元数据(如加/改名/重排列)可与读行的 snapshot 不一致。窗口窄(需单 statement 内 schema-cache 刷新)且数据行仍在钉的 snapshot id 读,故为一致性分歧而非保证错结果。 +- **suggestion**: 在 B5a latest 路径捕获 query-begin schema id 入 pin 并在该 id 解析 schema(让 beginQuerySnapshot 也返回 latest schemaId,经 getTableSchema(session,handle,connectorSnapshot) 在该 schemaId 建 pinned PluginDrivenSchemaCacheValue 并存为 pinnedSchema),使 getSchemaCacheValue 在 query begin 冻结 schema 版本。若 intentional 则显式 document 为 known reduction。 + +--- + +### 路径 13. cross-cutting: 旧逻辑/fallback sweep + +覆盖说明:追踪 paimon catalog 每个可达 cross-cutting dispatch 点,对比 post-cutover(NEW PluginDriven)与 LEGACY 流。验证每个残留 legacy 引用 post-cutover 为 DEAD(不可达)而非分歧 live fallback。详见下 "仍走旧逻辑 / fallback 清单" 章节。 + +#### Finding 13.1 — SHOW CREATE TABLE 仅在 connector 属性非空时发 LOCATION/PROPERTIES(legacy paimon 始终发) + +- **Severity**: NIT +- **New**: `Env.java:4946-4959` +- **Legacy**: `Env.java:4917-4928` +- **Difference**: legacy PAIMON_EXTERNAL_TABLE 分支(:4917-4928)无条件追加 `"\nLOCATION ''"` 和 PROPERTIES (...) 块,即使属性 map 为空。新 PLUGIN_EXTERNAL_TABLE 分支(:4947)将整个 LOCATION+PROPERTIES 发出 guard 于 `if (!properties.isEmpty())`。guard 为使其他 SPI connector(如 MaxCompute 返空 map)保持 comment-only 而加,但也改变 paimon 的理论 empty-map 情形。 +- **failureScenario**: 对真实 paimon 表不触发:PaimonConnectorMetadata.buildTableSchema 始终将 coreOptions().toMap()(总含 'path' 键)放入 schema properties(DataTable),故 properties 永不空,LOCATION/PROPERTIES 行始终渲染,匹配 legacy。分歧仅在(不出现的)paimon 表暴露零属性的假设中可达。 +- **suggestion**: 正确性无需改;guard intentional + benign(paimon 总暴露非空 coreOptions map 含 path)。可选加注释说明 guard 为与 always-emit legacy paimon DDL 的 deliberate 分歧点,防未来误判回退。 + +--- + +## new ↔

instead of the Java JNI reader. The C++ reader deserializes the split with Paimon's **native binary** format (`paimon::Split::Deserialize`). The new connector (`PaimonScanPlanProvider`) ignores the `enable_paimon_cpp_reader` session flag entirely and **always** serializes the split with Java object serialization (`InstantiationUtil.serializeObject`). So when a user (or the regression harness, which randomizes the flag) turns the flag on, BE's `PaimonCppReader::_decode_split` runs a native deserialize over a Java-serialized blob and fails hard with `Status::InternalError("paimon-cpp deserialize split failed: ...")`.

The flag `enable_paimon_cpp_reader` is read nowhere in the connector (verified: `grep` for `enable_paimon`/`getSessionProperties` in the connector main source returns nothing). The `planScan` method receives a `ConnectorSession session` (`:149-153`) but never threads it into `buildJniScanRange`. + +**Legacy honored the flag — the branch the connector dropped.** +`fe/fe-core/src/main/java/org/apache/doris/datasource/paimon/source/PaimonScanNode.java:260-268`: +``` +if (split != null) { + rangeDesc.setFormatType(TFileFormatType.FORMAT_JNI); + if (sessionVariable.isEnablePaimonCppReader() && split instanceof DataSplit) { + fileDesc.setPaimonSplit(PaimonUtil.encodeDataSplitToString((DataSplit) split)); + } else { + fileDesc.setPaimonSplit(PaimonUtil.encodeObjectToString(split)); + } + ... +} +``` +The two encoders differ by wire format: +- `PaimonUtil.encodeObjectToString` (`PaimonUtil.java:519-526`): `InstantiationUtil.serializeObject` + base64 → **Java serialization** (for the Java JNI reader). +- `PaimonUtil.encodeDataSplitToString` (`PaimonUtil.java:533-543`): `split.serialize(new DataOutputViewStreamWrapper(baos))` + base64 → **Paimon native binary** (javadoc: "compatible with paimon-cpp reader").

The Java JNI reader instead expects the Java-serialized blob. So the FE format MUST match the flag. + +**The flag is reachable and exercised, not theoretical.** +`enable_paimon_cpp_reader` is a visible, non-removed session var (`SessionVariable.java:2884-2887`, name constant `:774`), so `VariableMgr.toMap` emits it by name (`VariableMgr.java:930-948` skips only REMOVED/INVISIBLE). `ConnectorSessionBuilder.extractSessionProperties` (`ConnectorSessionBuilder.java:116-127`) forwards the whole `toMap` result into `ConnectorSession.getSessionProperties()`. The regression harness randomizes it (`SessionVariable.java:3875` `this.enablePaimonCppReader = random.nextBoolean();`). Default is `false`, so default reads are unaffected; flag-on reproduces deterministically. + +# Design + +Mirror the legacy branch inside the connector, as a small, pure, unit-testable seam — exactly the shape already used for the native-vs-JNI routing decision (`shouldUseNativeReader`, a static at `:366`). + +1. Read the flag once in `planScan` from the session: `boolean cppReader = isCppReaderEnabled(session);` where `isCppReaderEnabled` reads `session.getSessionProperties().get("enable_paimon_cpp_reader")` and parses it as boolean (default false). This is the only place the flag is consumed; no fe-core import — `ConnectorSession` and its `getSessionProperties()` are the established SPI channel (same channel MaxCompute uses for its tunables). + +2. Thread the flag into `buildJniScanRange(...)` as a new `boolean useCppFormat` parameter. + +3. Inside `buildJniScanRange`, select the encoder via a new pure static `encodeSplit(Split split, boolean useCppFormat)`: + - If `useCppFormat && split instanceof DataSplit` → Paimon-native: `((DataSplit) split).serialize(new DataOutputViewStreamWrapper(baos))` + STANDARD base64 (port of `encodeDataSplitToString`). + - Else → existing Java path: `encodeObjectToString(split)`. + + The `instanceof DataSplit` guard is **load-bearing parity**: non-`DataSplit` system splits (the `nonDataSplits` loop, `:206-210`) and the empty-RawFiles JNI fallback for a `DataSplit` (`:246-251`) MUST stay Java-serialized even when the flag is on, because the native binary format only exists for `DataSplit`. Both call sites pass the flag, but the static's guard keeps non-DataSplit on Java automatically — matching legacy's single `split instanceof DataSplit` gate. + +Constraints honored: +- **No fe-core import**: `DataOutputViewStreamWrapper` (paimon-common, already on the connector classpath — same package as the already-imported `org.apache.paimon.io.DataFileMeta`) and `DataSplit.serialize` are pure Paimon SDK. The flag comes through the connector SPI session, not via `SessionVariable`. +- **Minimal/surgical**: no new class; one new static encoder + one new boolean param + one flag-read helper, all in `PaimonScanPlanProvider`. `PaimonScanRange` and `PaimonTableHandle` are untouched (the wire property `paimon.split` and the BE-side `populateRangeParams` are format-agnostic — they carry an opaque base64 string either way; BE picks the decoder off `enable_paimon_cpp_reader`, which is already plumbed independently to BE via `SessionVariable.toThrift`/`query_options`). +- **Style match**: the pure-static + per-call-site-flag pattern is identical to `shouldUseNativeReader`/`supportNativeReader`. + +Note: BE already learns the flag through its own `query_options.enable_paimon_cpp_reader` (set by `SessionVariable.toThrift`, `SessionVariable.java:5526`) — that path is independent of the connector and unchanged.

Legacy gate = `enablePaimonCppReader && split instanceof DataSplit`; ported verbatim (flag via SPI session + the `instanceof DataSplit` guard inside `encodeSplit`). The Java-serialization default path is unchanged, so flag-off behavior is bit-for-bit identical to today. +- **Non-DataSplit / fallback splits**: must NOT switch to native even with the flag on (no native binary exists for them). The `instanceof DataSplit` guard preserves this; verified against legacy which only specializes `DataSplit`. A regression here (e.g. forcing native for all) would re-break system tables and the no-raw-file JNI fallback under the cpp reader — covered by a UT below. +- **Shared-code blast radius**: zero. Change is confined to `PaimonScanPlanProvider`. `PaimonScanRange`/`PaimonTableHandle`/thrift/BE are untouched; the wire property `paimon.split` stays an opaque base64 string and BE's reader selection already keys off its own `query_options.enable_paimon_cpp_reader` (independent path, unchanged). +- **Classpath**: `DataOutputViewStreamWrapper` is in paimon-common (transitive via paimon-core; same package as already-imported `org.apache.paimon.io.DataFileMeta`). No new dependency.

Precedence (file as base, user `hive.*` wins) matches `HMSBaseProperties.checkAndInit`. One subtle divergence to call out in tests: legacy keeps the loaded file as a live `HiveConf` and `addResource`s it (lazy, effective values resolved on read), whereas the fe-core hook eagerly flattens to a `Map` of effective values then re-`set`s them. For plain key/value `hive-site.xml` content these are equivalent; the only theoretical difference is XML `` flags or variable-substitution edge cases, which are not connection-critical and not exercised by HMS catalogs in practice. Acceptable and strictly closer to legacy than today's total drop. +- **Shared-code blast radius:** `ConnectorContext.loadHiveConfResources` is a NEW default method returning empty — zero behavior change for every other connector (maxcompute, jdbc siblings, trino) and for the `RecordingConnectorContext` test double (inherits the no-op default unless a test overrides it). `DefaultConnectorContext` gains one method; no existing method touched. The new `buildHmsHiveConf(props)` 1-arg overload delegates, so all existing callers/tests (`PaimonCatalogFactoryTest` 5 HMS tests, `PaimonConnector`) compile and behave unchanged. +- **Edge cases:** (a) `hive.conf.resources` absent/blank → hook gets blank → returns empty map → behaves exactly as today (no regression). (b) Referenced file missing → `CatalogConfigFileUtils` throws `IllegalArgumentException` ("Config resource file does not exist") which propagates out of CREATE CATALOG — fail-loud, matching legacy (today it is silently ignored, which is the very bug). This makes a previously-silent misconfiguration loud; intended per the finding's "at least make the drop loud." (c) Trino/plugin isolated classloaders: not applicable — paimon's `DefaultConnectorContext` runs in fe-core's classloader where `Config`/filesystem are reachable; only the resolved `Map` crosses into the connector, avoiding the `HiveConf`/`Configuration` cross-loader identity hazard noted at `PaimonConnector.java:152-157`. +- **Live-runtime caveat (unchanged by this fix):** the pre-existing B7 note that the live `metastore=hive` Thrift client is host-provided at cutover still stands; this fix only restores the file content into the `HiveConf` and does not alter the classloader story. + +# Test Plan + +## Unit Tests +All in the connector test dir; all PURE/offline (no live metastore). + +**`PaimonCatalogFactoryTest` (new tests; FAIL before fix because the 2-arg overload + base-merge do not exist / file keys are dropped):** + +1. `buildHmsHiveConfOverlaysResolvedHiveConfResourcesAsBase` — call `buildHmsHiveConf(props("uri","thrift://nn:9083"), map("hive.metastore.sasl.qop","auth-conf","hive.metastore.thrift.transport","custom"))`.

No `TimeUtils`/`DateUtils`. This matches `PaimonPredicateConverter` (already uses `java.time.LocalDate`/`ZoneOffset.UTC`/paimon `Timestamp`) and `PaimonConnectorMetadata.parseTimestampMillis` (already uses `java.time.ZoneId.of(session.getTimeZone())`). +2. **Match existing style** — extract the type switch as a `static` package-private method `serializePartitionValue(DataType, Object, String timeZone)`, mirroring how `shouldUseNativeReader` was extracted as a pure static for unit-testability (the existing `FakePaimonTable.newReadBuilder()` throws, so `planScan` can't be driven end-to-end offline; a pure static is the established testable seam in this file). +3. **Minimal change** — change one method signature (`getPartitionInfoMap` gains a `String timeZone` param), thread `session.getTimeZone()` from the single call site, add the static `serializePartitionValue`, add the needed `java.time` + paimon `Timestamp`/`DataType` imports. No change to `PaimonScanRange` (it already null-guards and empty-guards the map correctly). +4. **Parity behavior** — byte-faithful port of all 8 type cases, `Locale.ROOT` key lowercasing, and the "unsupported type → whole map dropped" rule. + +**Unsupported-type / null-map handling**: Legacy returns `null` for the whole map when any column is unsupported (binary), and the legacy native call site at `PaimonScanNode.java:457` then calls `setPaimonPartitionValues(null)`. The connector's `PaimonScanRange` already treats a null `partitionValues` as `Collections.emptyMap()` (`PaimonScanRange.java:71-73`) and `populateRangeParams` skips empty maps (`:214`), so emitting **no `columnsFromPath`** is the correct parity outcome. To keep the connector's existing non-null contract and avoid NPE risk, I will have `getPartitionInfoMap` **return `Collections.emptyMap()`** (instead of `null`) when any column is unsupported — functionally identical downstream (empty map ⇒ no `columnsFromPath`, same as legacy's null). This is the review's own recommended resolution ("不支持类型返回空 map ... 而非 Object.toString()"). + +**TZ semantics — IMPORTANT, distinct from predicate pushdown**: the connector-session-TZ memory note warns that paimon *predicate pushdown* must NOT use session-TZ (NTZ stays UTC). That caveat is about predicate literal→epoch conversion against stored file stats, and does NOT apply here. Partition-VALUE rendering is a separate concern and legacy explicitly DOES use the session TZ for the LTZ case (`PaimonUtil.java:623` `ZoneId.of(timeZone)` fed from `sessionVariable.getTimeZone()`). So for parity the connector must thread `session.getTimeZone()` into the LTZ case — and ONLY the LTZ case consumes it; all other cases ignore `timeZone`. + +**Bad-alias TZ (CST/PST) handling for the LTZ case**: legacy calls `ZoneId.of(timeZone)` directly with the raw stored Doris string, so legacy itself throws `DateTimeException` for Doris aliases like "CST"/"PST" (`ZoneId.of` rejects them; the connector cannot import the fe-core alias map). I will mirror legacy **exactly**: call `ZoneId.of(timeZone)` with no special degrade. If it throws, the exception propagates out of `planScan` — identical to legacy's behavior (legacy would throw the same `DateTimeException` from `serializePartitionValue`, NOT caught by its `catch (UnsupportedOperationException)`). This is the byte-parity, fail-loud choice consistent with `parseTimestampMillis`'s already-shipped rationale (a wrong zone ⇒ silently wrong partition values ⇒ wrong rows; degrading is unsafe with no BE re-apply for materialized partition values). I will NOT add a friendlier message here (keep the change minimal and behavior identical to legacy); the only realistic path to a bad alias for an LTZ *partition column* is exotic, and parity is the contract. + +# Implementation Plan + +**File: `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonScanPlanProvider.java`** (only file changed) + +1. **Add imports** (alongside existing `org.apache.paimon.*` and `java.*` import groups): + - `import org.apache.paimon.data.Timestamp;` + - `import org.apache.paimon.types.DataType;` + - `import java.time.LocalDate;` + - `import java.time.LocalTime;` + - `import java.time.ZoneId;` + - `import java.time.format.DateTimeFormatter;` + - `import java.util.Locale;` + (`BinaryRow`, `RowType`, `RowDataToObjectArrayConverter`, `LinkedHashMap`, `Collections`, `List`, `Map` already imported.) + +2. **Thread the session TZ at the single call site** in `planScan` (current `:213-215`): + ```java + for (DataSplit dataSplit : dataSplits) { + Map partitionValues = getPartitionInfoMap( + table, dataSplit.partition(), session.getTimeZone()); + ``` + +3. **Replace `getPartitionInfoMap` (`:383-400`)** with the type-aware port: + ```java + private Map getPartitionInfoMap(Table table, BinaryRow partitionValue, String timeZone) { + List partitionKeys = table.partitionKeys(); + if (partitionKeys == null || partitionKeys.isEmpty()) { + return Collections.emptyMap(); + } + RowType partitionType = table.rowType().project(partitionKeys); + RowDataToObjectArrayConverter converter = new RowDataToObjectArrayConverter(partitionType); + Object[] values = converter.convert(partitionValue); + + Map result = new LinkedHashMap<>(); + for (int i = 0; i < partitionKeys.size(); i++) { + try { + String value = serializePartitionValue( + partitionType.getFields().get(i).type(), values[i], timeZone); + result.put(partitionKeys.get(i).toLowerCase(Locale.ROOT), value); + } catch (UnsupportedOperationException e) { + // Legacy parity (PaimonUtil.getPartitionInfoMap): an unsupported partition column + // type (e.g. binary/varbinary) drops the ENTIRE map — BE then materializes no + // columnsFromPath for this split, rather than emitting non-deterministic [B@hash + // garbage.

The only intentional deviation is returning `Collections.emptyMap()` instead of `null` on unsupported type — downstream-equivalent (both ⇒ no `columnsFromPath`) and the existing `PaimonScanRange` already null-tolerates anyway, so this only *removes* a latent NPE surface, never changes emitted thrift. +- **Map key lowercasing change**: previously raw key, now `Locale.ROOT` lowercase. This matches legacy AND matches the projection path in `planScan` (`:167-169` already lowercases field names). Paimon column names from `rowType().getFieldNames()` are conventionally lowercase already, so for the common case this is a no-op; for mixed-case it now correctly aligns key casing with what BE's `columnsFromPath` matching expects (legacy contract). +- **Shared-code blast radius**: ZERO. `getPartitionInfoMap` is private with a single caller (`planScan`); the new `serializePartitionValue` is a new package-private static with one caller. No SPI signature changes, no fe-core touch, no change to `PaimonScanRange`/handle/metadata. JNI path is unaffected in correctness (BE's JNI reader gets partition info from the serialized split, not `columnsFromPath`; legacy set the map on JNI splits too, so keeping the corrected map on JNI ranges is strictly more-correct and harmless). +- **TZ edge case (CST/PST)**: byte-identical to legacy — `ZoneId.of(rawDorisAlias)` throws `DateTimeException`, propagating out of `planScan`. This is NOT a new regression: legacy threw the same way from the same `ZoneId.of(timeZone)`. It only affects LTZ-typed *partition columns* (rare) under a non-IANA session zone; for all standard zones ("UTC", "Asia/Shanghai", offsets) it is correct. Consistent with the already-shipped fail-loud rationale in `parseTimestampMillis`. +- **TIME case (over-stated finding)**: ported for faithful parity, but practically unreachable — paimon `TIME` maps to UNSUPPORTED in `PaimonTypeMapping` (both directions), so a TIME partition column cannot be created/projected through Doris; legacy's `(Long) value` cast would also throw if it ever ran on the converter's `Integer`. Porting it verbatim (cast to `Long`) keeps byte-parity; if it ever executes it throws `ClassCastException` exactly as legacy would, surfaced loudly rather than silently wrong. No behavior is made worse. +- **DATE cast `(Integer)`**: `RowDataToObjectArrayConverter` yields a boxed `Integer` for DATE (epoch-days) — verified against the legacy code that performs the identical cast. Safe. +- **Null partition value**: every case null-guards (returns `null`), preserved from legacy. `PaimonScanRange`/`ConnectorPartitionValues.normalize` already handle null entries (`columnsFromPathIsNull`). + +# Test Plan + +## Unit Tests + +New test class `fe/fe-connector/fe-connector-paimon/src/test/java/org/apache/doris/connector/paimon/PaimonPartitionValueRenderTest.java`, driving the new pure static `PaimonScanPlanProvider.serializePartitionValue(DataType, Object, String)` directly (package-private, same-package). This is the established testable seam because `FakePaimonTable.newReadBuilder()` throws so `planScan`/`getPartitionInfoMap` cannot be driven end-to-end offline — exactly why `shouldUseNativeReader` is also tested as a pure static. Each test encodes WHY (the BE consumes this string as `columnsFromPath`; a wrong string ⇒ wrong materialized rows), and each FAILS before the fix (raw `toString()`) and PASSES after. + +- `dateRendersAsIsoDateNotEpochDays`: `serializePartitionValue(DataTypes.DATE(), Integer.valueOf((int) LocalDate.of(2024,1,1).toEpochDay()), "UTC")` ⇒ `"2024-01-01"`.

RED before fix. +- `ltzShiftsUtcToSessionZone`: build `Timestamp.fromLocalDateTime(LocalDateTime.of(2024,1,1,0,0,0))` (the UTC wall clock), `serializePartitionValue(DataTypes.TIMESTAMP_WITH_LOCAL_TIME_ZONE(), ts, "Asia/Shanghai")` ⇒ `"2024-01-01T08:00:00"`. WHY: LTZ partition values are stored UTC and must be shown in the session zone; pre-fix renders the un-shifted UTC wall clock. Also assert with `"UTC"` ⇒ `"2024-01-01T00:00:00"` (no shift) to pin that the zone parameter is actually applied. RED before fix (raw `toString()` ignores zone). +- `ntzRendersIsoNoZoneShift`: `serializePartitionValue(DataTypes.TIMESTAMP(), Timestamp.fromLocalDateTime(LocalDateTime.of(2024,1,1,1,2,3)), "Asia/Shanghai")` ⇒ `"2024-01-01T01:02:03"` regardless of session zone. WHY: pins the NTZ-stays-wall-clock invariant (the memory-note caveat: NTZ must NOT be zone-shifted). Guards against a future "shift everything" regression. (Coincidentally green pre-fix; its value is locking intent.) +- `binaryYieldsUnsupported`: `assertThrows(UnsupportedOperationException.class, () -> serializePartitionValue(DataTypes.BYTES(), new byte[]{1,2}, "UTC"))`. WHY: binary must NOT be rendered as `[B@hash`; the contract is "throw so the caller drops the whole map" (no `columnsFromPath`). MUTATION: any render path for binary ⇒ no throw ⇒ red. RED before fix (raw `toString()` returns `[B@...` and never throws). +- `floatDoubleUseToStringRender`: `serializePartitionValue(DataTypes.FLOAT(), 1.5f, "UTC")` ⇒ `"1.5"`; `DataTypes.DOUBLE(), 2.25d` ⇒ `"2.25"`. Parity-locking (matches legacy `Float/Double.toString`). +- `nullValueRendersNull`: each typed case with `value=null` ⇒ `null`. Locks the null-guard parity. + +New (or extended `PaimonScanPlanProviderTest`) test exercising the **map-level** contract via a thin overload — since `getPartitionInfoMap` needs a real `BinaryRow`+converter which is heavy offline, the map-level "unsupported ⇒ empty map" and "key lowercased" behavior is asserted by a focused test only if a lightweight `BinaryRow` can be built; otherwise the static-seam tests above (binary-throws + ISO renders) plus a code-review-visible single call site fully cover intent. Preferred minimal addition: +- `keyLowercasedAndUnsupportedDropsMap` (only if a real `BinaryRow` for the partition is constructible with the paimon `BinaryRowWriter` available on the test classpath): assert a mixed-case DATE partition key renders lowercase in the result map, and a binary partition column yields `Collections.emptyMap()`. If `BinaryRow` construction proves brittle offline, omit and rely on the static-seam tests (the map wrapper is a trivial 6-line loop fully covered by the seam tests + the single-call-site thread of `session.getTimeZone()`). + +All new tests are offline, no fe-core, no mockito (pure paimon `DataTypes`/`Timestamp` + JUnit5, matching the existing connector test style and classpath — verified `DataTypes.DATE/TIMESTAMP_WITH_LOCAL_TIME_ZONE/FLOAT/DOUBLE/TIME` and `Timestamp.fromLocalDateTime` are on the test classpath). + +## E2E Tests + +Live-only / CI-skipped (no paimon cluster in unit CI; gated like `PaimonLiveConnectivityTest`). The end-to-end proof is a regression-test SQL: create a paimon table partitioned by a DATE column (and separately an LTZ column) with ORC/Parquet data files that are native-reader eligible (not binlog/audit_log, `force_jni_scanner=false`), then `SELECT date_part_col FROM t` under a non-UTC `SET time_zone=...` session and assert the returned partition column values equal the legacy/expected `"2024-01-01"` (and the correctly-shifted LTZ datetime) rather than `"19723"`/un-shifted UTC. This cannot run in the connector unit module (needs BE + a real warehouse + native reader), so it is documented as live-only; the unit tests above fully cover the FE-side rendering logic that is the actual defect. + +--- + +# ✅ IMPL SUMMARY (2026-06-11) + +**Status: DONE — build+UT green (PaimonPartitionValueRenderTest 7/0; PaimonScanPlanProviderTest 8/0 unchanged; imports clean; HEAD uncommitted).** + +## Fix (1 production file: `PaimonScanPlanProvider.java`) +- Added imports: paimon `Timestamp`, `DataType`; `java.time.{LocalDate,LocalTime,ZoneId,format.DateTimeFormatter}`; `java.util.Locale` (alphabetical, checkstyle-clean). +- Threaded `session.getTimeZone()` into the single call site (`getPartitionInfoMap(table, dataSplit.partition(), session.getTimeZone())`). +- `getPartitionInfoMap` now lower-cases keys via `Locale.ROOT`, calls the new per-type `serializePartitionValue`, and on `UnsupportedOperationException` (binary) returns `Collections.emptyMap()` (legacy null-map parity → no `columnsFromPath`). +- Added pure static `serializePartitionValue(DataType, Object, String timeZone)` — byte-faithful port of all 8 legacy cases (scalar/decimal/char/varchar→toString; FLOAT/DOUBLE→Float/Double.toString; DATE→ISO_LOCAL_DATE; TIME→ISO_LOCAL_TIME; NTZ→ISO_LOCAL_DATE_TIME; LTZ→UTC→session-TZ shift; BINARY→throws).

The most common trigger is paimon **primary-key tables**: paimon forces every PK column to `NOT NULL`, so under the new path nearly every paimon PK table now exposes `NOT NULL` Doris columns where legacy exposed nullable ones. Nereids uses column nullability to drive null-rejecting simplifications (e.g. `IS NULL` folding, `Coalesce`/anti-join rewrites).

The gate changes from "metastore is `PaimonRestMetaStoreProperties`" to "table's `fileIO` is `RESTTokenFileIO`" — equivalent for the read path (a REST catalog table yields a `RESTTokenFileIO`; non-REST yields a different `FileIO`), and strictly more precise (won't try to vend on a REST catalog table that happens to have a non-token FileIO). Fail-soft on any extraction/normalization error matches legacy (`AbstractVendedCredentialsProvider` returns null/empty on exception). +- **Shared-code blast radius:** The new `ConnectorContext` method is a `default` no-op, so every other connector (maxcompute, etc.) and every existing `ConnectorContext` implementation (including the test `RecordingConnectorContext`) compiles and behaves unchanged. The `DefaultConnectorContext` ctor gains an overload; the existing 2-arg/3-arg ctors are preserved, and `CatalogFactory.java:106` keeps using the no-vended overload, so non-plugin-driven paths are untouched. The `PluginDrivenExternalCatalog` change only adds a supplier argument. +- **Static-key precedence:** Overlaying vended after static means a catalog that *also* set static `s3.*` keys gets the vended token winning — matches legacy (`getStoragePropertiesMapWithVendedCredentials` replaces base with vended when vended succeeds). Note static `location.s3.*` keys remain raw (un-normalized) and are not consumed by BE's native S3 client — that's the separate sibling P9 finding and out of scope here; this fix does not regress it. +- **Token freshness / expiry:** `validToken()` returns a currently-valid token at plan time (legacy did the same in `doInitialize`). Long-running scans that outlive token TTL are a pre-existing legacy limitation, not introduced here. +- **Edge cases:** empty token map → empty overlay (no-op); non-REST FileIO → empty (no-op); `context == null` (offline unit tests using the 2-arg ctor) → skipped, so the offline harness keeps working; null `validToken()`/`token()` → empty, no NPE. JNI path unchanged (it never used `location.*` creds; BE self-serves from the serialized `RESTTokenFileIO`). +- **No-fe-core-import rule:** The connector only references `org.apache.paimon.rest.{RESTToken,RESTTokenFileIO}` and `org.apache.paimon.fs.FileIO` (paimon SDK) plus the `ConnectorContext` SPI. No `org.apache.doris.datasource.*` import added to the connector.

The positive `RESTTokenFileIO.validToken()` branch is covered by the bridge test + E2E (a `RESTTokenFileIO` cannot be hand-constructed offline without a live REST stack). FAILS before if extraction logic were wrong; the current code has no extraction at all, so these tests pin the new contract. + +2. `PaimonScanPlanProviderTest.getScanNodeProperties_overlaysVendedCreds` (new): use a hand-written `ConnectorContext` double whose `vendStorageCredentials(raw)` returns a fixed map `{AWS_ACCESS_KEY=ak, AWS_SECRET_KEY=sk, AWS_TOKEN=tok, AWS_ENDPOINT=ep}` regardless of input, wire it through the 3-arg `PaimonScanPlanProvider` ctor with a `FakePaimonTable`. Assert the returned props contain `location.AWS_ACCESS_KEY=ak` … and that a colliding static key is overridden by the vended value. This FAILS before the fix (no overlay loop, no context param) and PASSES after. INTENT: the connector forwards normalized vended creds to BE under `location.*` with vended-wins precedence. + +3. `PaimonScanPlanProviderTest.getScanNodeProperties_noContext_unchanged` (new): construct with the 2-arg ctor (`context == null`) and assert the property set equals the pre-fix static-only set — guards the offline path and proves no NPE / no behavior change when the hook is absent. + +4. `DefaultConnectorContextVendTest` (new, fe-core test dir — fe-core may use Mockito/real objects): feed a raw OSS token map (`fs.oss.accessKeyId`/`fs.oss.accessKeySecret`/`fs.oss.securityToken`/`fs.oss.endpoint`, mirroring `PaimonVendedCredentialsProviderTest`) into `vendStorageCredentials` and assert the result contains the normalized BE keys `AWS_ACCESS_KEY`/`AWS_SECRET_KEY`/`AWS_TOKEN`/`AWS_ENDPOINT` (and that an empty input yields empty). This pins that the bridge reuses `StorageProperties.createAll` correctly and matches the legacy `PaimonVendedCredentialsProviderTest` + `getBackendPropertiesFromStorageMap` expectations (which already asserts `AWS_*` keys at `PaimonVendedCredentialsProviderTest.java:286-291`). FAILS before (method is a no-op default) and PASSES after. + +5. `RecordingConnectorContext` (connector test fake) needs no change — it inherits the no-op default, confirming the SPI addition is backward compatible. + +## E2E Tests +- A regression case under `regression-test/` analogous to the existing `test_paimon_s3.groovy`, but for a **REST/DLF catalog that vends per-table OSS/S3 credentials with no static `s3.*`/`oss.*` keys**, then `SELECT` a native-readable (ORC/Parquet) table and assert correct rows. This is **live-only / CI-skipped**: it requires a real Paimon REST server (or DLF) that issues vended STS tokens and a private OSS/S3 bucket — there is no offline double for `RESTTokenFileIO.validToken()` (it calls the REST server). Mark it gated behind the existing live-credential regression conf (same gating model as the live `PaimonLiveConnectivityTest`).

It never ported the **primary** translation. In legacy the primary translation came from `StorageProperties.getHadoopStorageConfig()`, applied separately: + +- **filesystem/hms**: `PaimonHMSMetaStoreProperties.buildHiveConfiguration` (fe-core `PaimonHMSMetaStoreProperties.java:80-84`) iterates `storagePropertiesList` and `conf.addResource(sp.getHadoopStorageConfig())` BEFORE the `appendUserHadoopConfig` overlay. The filesystem/jdbc path feeds the same `getOrderedStoragePropertiesList()` into `CatalogContext` (`PaimonExternalCatalog.createCatalog:147` → `initializeCatalog`). +- **dlf**: `PaimonAliyunDLFMetaStoreProperties.initializeCatalog` (fe-core `PaimonAliyunDLFMetaStoreProperties.java:90-95`) selects the OSS/OSS_HDFS `StorageProperties` and `ossProps.getHadoopStorageConfig().forEach(hiveConf::set)`. + +For S3, `getHadoopStorageConfig` is `AbstractS3CompatibleProperties.appendS3HdfsProperties` (fe-core `AbstractS3CompatibleProperties.java:272-295`): from the canonical `s3.*`/`AWS_*` aliases it sets `fs.s3.impl`, `fs.s3a.impl`, `fs.s3a.endpoint`, `fs.s3a.endpoint.region`, `fs.s3.impl.disable.cache`, `fs.s3a.impl.disable.cache`, `fs.s3a.aws.credentials.provider`, `fs.s3a.access.key`, `fs.s3a.secret.key`, optional `fs.s3a.session.token`, and connection/path-style keys. + +For OSS, it is `OSSProperties.initializeHadoopStorageConfig` (fe-core `OSSProperties.java:315-326`): the S3A block above PLUS `fs.oss.impl` (Jindo), `fs.AbstractFileSystem.oss.impl`, `fs.oss.accessKeyId`, `fs.oss.accessKeySecret`, optional `fs.oss.securityToken`, `fs.oss.endpoint`, `fs.oss.region`. The canonical OSS aliases are declared on `OSSProperties` fields (fe-core `OSSProperties.java:48-91`): endpoint = `{oss.endpoint, s3.endpoint, AWS_ENDPOINT, endpoint, dlf.endpoint, dlf.catalog.endpoint, fs.oss.endpoint}`, accessKey = `{oss.access_key, s3.access_key, ..., dlf.access_key, fs.oss.accessKeyId}`, etc. + +So the connector's allow-list mismatches the keys Doris users actually pass (and the keys its own regression suite passes), and the credentials never reach the Paimon FileIO `Configuration`/`HiveConf`. Confirmed PaimonCatalogFactory imports zero `org.apache.doris.*` and currently sets none of the `fs.s3.impl`/`fs.s3a.impl`/credentials-provider keys. + +# Design + +Add a **canonical-key translation step** to `applyStorageConfig`, ported from legacy `appendS3HdfsProperties` + `OSSProperties.initializeHadoopStorageConfig`, keeping it fe-core-free (pure Map→setter, no `StorageProperties` import). The existing two branches (paimon.* re-key, raw fs./dfs./hadoop. passthrough) are **preserved unchanged** for backward compatibility — we only ADD recognition of the canonical aliases the connector currently drops. + +Principles, matching existing style: + +1. **Alias resolution via `firstNonBlank`** over the same alias lists legacy `@ConnectorProperty(names=...)` declared (literal string keys, mirroring how `DLF_*`/`HMS_URI` aliases are already declared as literal arrays in `PaimonConnectorProperties`). No fe-core types. +2. **S3A block** (both flavors): when an access key is resolvable, set `fs.s3a.access.key`/`fs.s3a.secret.key`/`fs.s3a.aws.credentials.provider=...SimpleAWSCredentialsProvider`, optional `fs.s3a.session.token`; always set `fs.s3.impl`/`fs.s3a.impl` + `disable.cache`; set `fs.s3a.endpoint` and `fs.s3a.endpoint.region` when present. This is the verbatim legacy `appendS3HdfsProperties` minus the FE-config-derived connection/timeout defaults (those are not credentials; the existing code already omits them, and Hadoop S3A has its own defaults — keep that minimal-change boundary). +3. **OSS block** (additive): when an OSS access key / endpoint / region is resolvable from canonical `oss.*` aliases, set the Jindo `fs.oss.*` keys (`fs.oss.impl`, `fs.AbstractFileSystem.oss.impl`, `fs.oss.accessKeyId`, `fs.oss.accessKeySecret`, optional `fs.oss.securityToken`, `fs.oss.endpoint`, `fs.oss.region`). Because the canonical OSS endpoint/key aliases overlap with `s3.*` (legacy `OSSProperties` shares them), the S3A block also gets populated from the same values — which is exactly legacy behavior (`OSSProperties.initializeHadoopStorageConfig` calls `super` = the S3A block first). This is desirable: it preserves the legacy "even for OSS we append S3 props for `s3://`-scheme back-compat" comment (fe-core `AbstractS3CompatibleProperties.java:266-269`). +4. **Precedence**: the existing `paimon.*` re-key and raw `fs./dfs./hadoop.` passthrough run AFTER the canonical translation, so an explicitly-passed `fs.s3a.access.key` or `paimon.s3.access-key` still wins (last-write). This matches legacy ordering: `addResource(getHadoopStorageConfig())` (canonical) THEN `appendUserHadoopConfig`/raw (paimon.*) overlay. +5. **Endpoint-from-region derivation is NOT ported** for the filesystem S3 case (legacy `setEndpointIfPossible` lives in `AbstractS3CompatibleProperties` and constructs from URL/region). The regression and documented config always pass an explicit endpoint; deriving it would require porting the S3/OSS endpoint-pattern machinery (large, fe-core-coupled). We set `fs.s3a.endpoint`/`fs.oss.endpoint` only when the user supplied one. For the **DLF** flavor, `buildDlfHiveConf` already derives the DLF *metastore* endpoint from region (`PaimonCatalogFactory.java:466-470`); the OSS *storage* endpoint for DLF should likewise be derivable — see Implementation Plan note (mirror `OSSProperties.getOssEndpoint` only inside the OSS block to keep DLF parity, since DLF users typically pass `dlf.region`/`oss.region` not `oss.endpoint`). + +Helper method `firstNonBlank` already exists and is exactly the alias-priority primitive needed. + +# Implementation Plan + +All changes in `PaimonCatalogFactory.java` (one file; tests in a second).

(Optional, DLF parity) OSS endpoint-from-region for DLF + +Legacy DLF derives the OSS endpoint from region (`OSSProperties.getOssEndpoint(region, accessPublic)`). `buildDlfHiveConf` already computes `accessPublic` and derives the DLF metastore endpoint. To match DLF parity when a user passes only `dlf.region`/`oss.region` (no `oss.endpoint`), derive `fs.oss.endpoint = "oss-" + region + (accessPublic ? "" : "-internal") + ".aliyuncs.com"` inside `buildDlfHiveConf` after `applyStorageConfig`, only when `fs.oss.endpoint` is still unset. Keep this DLF-local (do not put region-derivation in the shared `applyCanonicalOssConfig`, since the filesystem S3/OSS flavor legacy required an explicit endpoint there). This is a small, additive overlay in `buildDlfHiveConf` and can be scoped out if we want the absolute minimal credential-only fix; flag it explicitly in the PR so the reviewer decides. Recommended to include for DLF Finding 9.2 completeness. + +### Update Javadoc + +Amend the `applyStorageConfig` and `buildHadoopConfiguration` Javadocs to state that canonical `s3.*`/`oss.*`/`AWS_*` aliases are now translated to `fs.s3a.*`/`fs.oss.*` (ported from legacy `appendS3HdfsProperties` + `OSSProperties.initializeHadoopStorageConfig`), in addition to the `paimon.*` re-key and raw passthrough. + +# Risk Analysis + +**Parity vs legacy** +- S3A block: ports the credential-bearing subset of `appendS3HdfsProperties` verbatim (impl/disable-cache/endpoint/region/credentials-provider/access/secret/token). Intentionally omits the connection/timeout/path-style keys (`fs.s3a.connection.maximum`, `...request.timeout`, `...path.style.access`) — those are not credentials and Hadoop S3A supplies its own defaults; the pre-fix code already set none of them, so omitting them is the minimal-change boundary, not a regression. If a deployment relied on `use_path_style`, that is a separate, pre-existing gap (call out in PR, defer). +- Endpoint-from-region/URL derivation (`setEndpointIfPossible`) is NOT ported for filesystem; documented config always supplies an explicit endpoint, and porting the endpoint-pattern engine would pull in fe-core-coupled regex machinery. DLF region-derivation handled locally (item 3). +- OSS block ports `OSSProperties.initializeHadoopStorageConfig` (Jindo impls + `fs.oss.*` credentials/endpoint/region). The Aliyun Jindo class names are hard-coded literals, matching the existing `appendDlfOptions` pattern that already hard-codes `com.aliyun.datalake...ProxyMetaStoreClient` to avoid the compile dep. + +**Shared-code blast radius** +- `applyStorageConfig` is called by `buildHadoopConfiguration` (filesystem, jdbc), `buildHmsHiveConf` (hms), `buildDlfHiveConf` (dlf). Adding canonical translation there fixes filesystem S3/OSS (Finding 9.1) and DLF OSS (Finding 9.2) in one place, and also improves hms/jdbc when canonical keys are used — all strictly additive (previously dropped keys now translated). +- **Back-compat**: the existing `paimon.*` re-key and raw `fs./dfs./hadoop.` branches are unchanged and run AFTER the canonical translation, so any user already passing `paimon.s3.access-key` or a raw `fs.s3a.access.key` gets identical output (their explicit key overwrites, last-write-wins — matching legacy `addResource(...)` then `appendUserHadoopConfig` ordering). No existing test should change behavior. + +**Edge cases** +- Anonymous / no-credential public buckets: when `ak` is null we still set `fs.s3.impl`/`fs.s3a.impl`/`disable.cache` and endpoint/region but no credentials provider — matches legacy (`appendS3HdfsProperties` only sets the provider/keys inside the `isNotBlank(accessKey)` guard). +- Mixed `s3.*` + `oss.*` keys: S3A block populated from s3 aliases, OSS block from oss aliases; both emitted, no collision (different key namespaces). Legacy does the same (OSS appends S3A then OSS keys). +- DLF gate interaction: `requireOssStorageForDlf` still runs first in `PaimonConnector.createCatalog`; with canonical `oss.*` now translated, the gate-passes-but-no-creds mismatch is closed. +- `s3.endpoint` is also a legacy OSS alias. Because OSS detection keys off `oss.*`/`fs.oss.*`/`dlf.*` only, a pure-`s3.*` config does NOT trigger the OSS Jindo block (correct — it is an S3 catalog); a pure-`oss.*` config triggers both blocks (correct — legacy OSS appends S3A too). + +# Test Plan + +## Unit Tests +New tests in `PaimonCatalogFactoryTest.java` (matching the existing offline, plain-map, no-Mockito style and the existing `buildHadoopConfigurationNormalizesS3PrefixesAndCopiesRawKeys` / `buildDlfHiveConf*` tests).

The JDBC reference `JdbcConnectorMetadata.java:142-153` shows the established override shape: compute row count, return `Optional.of(new ConnectorTableStatistics(rowCount, -1))` when `rowCount >= 0`, else `Optional.empty()`. + +# Design + +Override `getTableStatistics` in `PaimonConnectorMetadata`, computing the row count by summing `Split.rowCount()` over the planned splits of the resolved live `Table` — exactly the legacy computation, ported into the connector. + +Two constraints drive the shape: + +1. **No fe-core import** — respected: the fix lives entirely in the connector module and uses only paimon SDK types (`Table`, `Split`) plus the SPI `ConnectorTableStatistics` / `Optional`. No new fe-core dependency. + +2. **Offline unit-testability via a seam** — this is the load-bearing design decision and the reason I do NOT inline `table.newReadBuilder().newScan().plan().splits()` directly in the metadata method. The whole MVCC/time-travel logic was deliberately structured so `PaimonConnectorMetadata` calls plain-`long`-returning `PaimonCatalogOps` seam methods (see the seam Javadoc at `PaimonCatalogOps.java:79-83`: "return plain `long`s ... so the metadata layer's logic ... is unit-testable offline with `RecordingPaimonCatalogOps`"). The test double `FakePaimonTable.newReadBuilder()` THROWS `UnsupportedOperationException` (`FakePaimonTable.java:237-239`), so a metadata method that called `newReadBuilder()` directly could never be exercised offline. To stay consistent with the module's established pattern AND keep the new logic testable, add a single `long rowCount(Table table)` method to the `PaimonCatalogOps` seam: + + - `CatalogBackedPaimonCatalogOps.rowCount(Table)` does the real paimon work (`newReadBuilder().newScan().plan().splits()` sum), mirroring legacy line-for-line. + - `PaimonConnectorMetadata.getTableStatistics` resolves the table via the existing `resolveTable(handle)` (the same sys-aware resolver every metadata read path uses), calls `catalogOps.rowCount(table)`, applies the legacy `>0 ? n : UNKNOWN` rule, and wraps in `ConnectorTableStatistics(rowCount, -1)` (dataSize left UNKNOWN, matching JDBC reference and the fact legacy never computed a base-table dataSize here). + +`resolveTable` is sys-aware (`PaimonConnectorMetadata.java:931-937` → `PaimonTableResolver.resolve`), so a sys handle resolves its OWN synthetic table and `rowCount` plans the sys table's splits — this single override gives BOTH normal and sys paimon tables their real count, closing Finding 5.1 with the same code (no separate sys path needed, mirroring how legacy had two parallel-but-identical `fetchRowCount` bodies). + +dataSize: returned as -1 (UNKNOWN). Legacy `fetchRowCount` produced only a row count; there is no legacy base-table dataSize to port, and JDBC's reference override also returns dataSize=-1. Keeping dataSize unknown is faithful and avoids inventing a number. + +Error handling: a planning failure (remote IO, etc.) should NOT crash stats collection (which runs in background analysis / SHOW paths). Return `Optional.empty()` (→ FE falls back to -1) on exception, logging a warning — consistent with the connector's other best-effort read paths (e.g. `listDatabaseNames` `PaimonConnectorMetadata.java:96-99`, `collectPartitions` swallowing `TableNotExistException` at :869-873). This preserves the legacy END STATE (-1) on failure without a louder regression than legacy (legacy would have propagated, but legacy ran inside `fetchRowCount` whose callers tolerate exceptions becoming -1; empty-on-failure is the safer, equivalent-visible-result choice and matches the SPI's empty-if-unavailable contract). + +# Implementation Plan + +**File 1 — `fe/fe-connector/fe-connector-paimon/src/main/java/org/apache/doris/connector/paimon/PaimonCatalogOps.java`** + +Add one seam method to the interface (next to the E5 MVCC lookups block, with Javadoc matching the existing seam-rationale style): + +```java +/** + * Returns the total row count of {@code table} = sum of {@code split.rowCount()} over + * {@code table.newReadBuilder().newScan().plan().splits()} (legacy + * PaimonExternalTable.fetchRowCount / PaimonSysExternalTable.fetchRowCount).

Legacy summed `split.rowCount()` over `newReadBuilder().newScan().plan().splits()` and returned `>0 ? n : -1`; the seam impl is identical and the metadata wrapper reproduces the `>0` gate and the 0→UNKNOWN mapping. The only intentional divergence is failure handling (legacy let the exception propagate up `fetchRowCount`; we return empty→-1). The user-visible result is the same fallback (-1) but we avoid surfacing a transient planning error as a query-killing exception during background stats collection — strictly safer, and aligned with the SPI's empty-if-unavailable contract and the module's other best-effort read paths. +- **dataSize**: -1 (UNKNOWN). Legacy never produced a base-table dataSize in `fetchRowCount`, so this is not a regression; any future dataSize work is additive. +- **Shared-code blast radius**: Adding a method to the `PaimonCatalogOps` interface forces every implementor to provide it. There are exactly two: `CatalogBackedPaimonCatalogOps` (production, updated) and `RecordingPaimonCatalogOps` (test, updated). I grepped the module; no other implementor exists. `ConnectorStatisticsOps` / `ConnectorTableStatistics` are untouched, so no other connector (JDBC, MaxCompute) is affected. `fetchRowCount` in fe-core is untouched. +- **Cost-model direction**: Going from a constant -1 to a real positive count CHANGES plans (re-enables join reorder, may flip broadcast/shuffle). This is the intended correction (restoring legacy behavior). It is a planning change, not a correctness change — results stay identical; only plan shape/perf moves toward the legacy baseline. +- **Edge cases**: + - Empty table (0 rows) → `rowCount==0` → empty → -1, matching legacy (which logged and returned -1). + - System tables → resolved via sys-aware `resolveTable`; `rowCount` plans the sys table's own splits. Closes Finding 5.1 with the same code path; no extra sys branch. + - Time-travel / branch handles: `resolveTable` honors the handle's pinned identity (branch/scan options already on the handle), so stats reflect the handle's view. In practice `fetchRowCount` is called on the base table object (analysis path), so the handle is the latest base — but the code is correct for any handle the SPI is asked about. + - Planning cost: each `getTableStatistics` call drives a real `plan()` (one remote scan-plan), same cost as legacy `fetchRowCount`. Called from analysis / SHOW paths, not per-query-hot, so acceptable and unchanged from legacy. + +# Test Plan + +## Unit Tests + +New test class `PaimonConnectorMetadataStatisticsTest` in `fe/fe-connector/fe-connector-paimon/src/test/java/org/apache/doris/connector/paimon/`, driving a `RecordingPaimonCatalogOps` fake (no Mockito, fully offline), mirroring `PaimonConnectorMetadataMvccTest`'s `metadataWith(ops)` pattern. Each test FAILS before the fix (default SPI returns `Optional.empty()` for every input, so the positive-count and sys assertions fail) and PASSES after. + +Intent encoded (WHY, not just WHAT): + +1. **`positiveRowCount_returnedAsStatistics`** — `ops.rowCount = 42`; build a base `PaimonTableHandle` with `setPaimonTable(fakeTable)`; assert `getTableStatistics(...)` returns present with `getRowCount()==42` and `getDataSize()==-1`. WHY: a real positive count must reach the FE cost model (not -1) so join-reorder is not force-disabled. Also assert `ops.log` contains `"rowCount"` and `ops.lastRowCountTable == fakeTable`, proving the metadata layer planned the RESOLVED table (not some other handle) — locks the intent that stats are computed from the table the handle denotes. + +2. **`zeroRowCount_mapsToUnknownEmpty`** — `ops.rowCount = 0`; assert result is `Optional.empty()`. WHY: encodes the legacy 0→UNKNOWN(-1) contract; a future change that returned `(0,-1)` instead of empty would corrupt the FE which treats 0 as a real cardinality. This test fails if someone drops the `>0` gate. + +3. **`planningFailure_returnsEmptyNotThrow`** — a `RecordingPaimonCatalogOps` subclass (or a flag) whose `rowCount` throws `RuntimeException`; assert `getTableStatistics` returns `Optional.empty()` and does NOT propagate. WHY: stats collection must be best-effort; a transient remote failure must not kill the query/analysis. Locks the deliberate divergence from legacy's propagate-up behavior. + +4. **`systemTableUsesResolvedSysTable`** — build a sys handle via `PaimonTableHandle.forSystemTable(db, tbl, "snapshots", false)` with `setPaimonTable(sysFake)`; `ops.rowCount = 7`; assert present with rowCount==7 and `ops.lastRowCountTable == sysFake`. WHY: proves the single override serves system tables through the sys-aware `resolveTable` (closes Finding 5.1) — a future refactor that special-cased only normal tables would fail this. + +(`RecordingPaimonCatalogOps` gains the `rowCount` field + `lastRowCountTable` capture described above; `FakePaimonTable` is reused as-is — these tests never call `newReadBuilder()` because the seam is faked, which is the whole point of the seam.) + +## E2E Tests + +Live-only / CI-skipped, because a real row count requires a live paimon catalog with committed snapshots; the module's `PaimonLiveConnectivityTest` is the existing live harness and is not run in the offline gate. Recommended live regression (paimon p2 external suite, gated on a live paimon env): after `CREATE CATALOG` + `USE` a known paimon table with N committed rows, assert `SELECT COUNT(*)` and the reported stats agree — specifically that `SHOW TABLE STATUS`/`information_schema.tables.table_rows` reports N (not -1) for both a normal table AND a `tbl$snapshots` system table, matching the pre-migration (legacy) baseline. Note in the suite that this is a stats-only assertion (no row-correctness change) and that it must run against the same fixture used for the legacy parity baseline so any drift from legacy `fetchRowCount` is caught. This cannot run in the offline unit gate (no live catalog), hence CI-skipped/live-only. + +--- + +# ✅ IMPL SUMMARY (2026-06-11) + +**Status: DONE — build+UT green (PaimonConnectorMetadataStatisticsTest 4/0; PaimonConnectorMetadataMvccTest 37/0 unchanged; imports clean; HEAD uncommitted).** + +## Fix (3 production + 1 test-fake file, all in connector module; fe-core untouched) +- `PaimonCatalogOps.java`: added `long rowCount(Table)` to the interface + `import org.apache.paimon.table.source.Split`; implemented in `CatalogBackedPaimonCatalogOps` (sum `split.rowCount()` over `newReadBuilder().newScan().plan().splits()`). +- `PaimonConnectorMetadata.java`: added `import ConnectorTableStatistics` + the `getTableStatistics` override — resolves the table via the sys-aware `resolveTable`, calls `catalogOps.rowCount`, applies legacy `>0 ? n : UNKNOWN`, wraps `(rowCount, -1)`; best-effort `try/catch → Optional.empty()` on planning failure. +- `RecordingPaimonCatalogOps.java` (test fake): added `rowCount` / `lastRowCountTable` / `throwOnRowCount` + the `rowCount` override (required for module compile). + +## Tests (new `PaimonConnectorMetadataStatisticsTest`, 4): positive→stats(+lastRowCountTable proof), zero→empty, planning-failure→empty-not-throw, system-table→resolved-sys-table. + +## Notes +- Single override serves normal AND sys paimon tables via the sys-aware `resolveTable` (closes Finding 5.1; no separate sys path). +- dataSize left UNKNOWN(-1): legacy computed none here. +- The only two `PaimonCatalogOps` implementors (production `CatalogBackedPaimonCatalogOps`, test `RecordingPaimonCatalogOps`) both updated — verified no other implementor exists. + +## Live-e2e (gated, NOT run): SHOW TABLE STATUS / information_schema.tables.table_rows == N (not -1) for a normal table AND a `tbl$snapshots` sys table, against the legacy-parity fixture. diff --git a/plan-doc/tasks/designs/P5-fix-FIX-TZ-ALIAS-design.md b/plan-doc/tasks/designs/P5-fix-FIX-TZ-ALIAS-design.md new file mode 100644 index 00000000000000..fbeb1d942f11da --- /dev/null +++ b/plan-doc/tasks/designs/P5-fix-FIX-TZ-ALIAS-design.md @@ -0,0 +1,160 @@ +# Problem + +`FOR TIME AS OF ''` against a Paimon table fails with a `DorisConnectorException` whenever the session `time_zone` is a Doris zone alias that `java.time.ZoneId.of(String)` does not recognize — specifically **CST, PST, EST**.

These belong in the paimon time-travel regression group (live, requires a real Paimon catalog with multiple snapshots), so they are not part of the connector unit suite; the unit tests above provide the byte-parity coverage deterministically without a cluster. + +--- + +# ✅ IMPL SUMMARY (2026-06-11) + +**Status: DONE — build+UT green (PaimonConnectorMetadataMvccTest 37/0; imports clean; HEAD uncommitted).** + +## Fix (1 production file: `PaimonConnectorMetadata.java`) +- Added `private static final Map SESSION_TIME_ZONE_ALIASES` built in a static block: `new TreeMap<>(String.CASE_INSENSITIVE_ORDER)` → `putAll(ZoneId.SHORT_IDS)` → 4 overrides (CST/PRC→Asia/Shanghai, UTC/GMT→UTC) → `Collections.unmodifiableMap`. **Full SHORT_IDS map per the HANDOFF correction** (4-entry-only leaves PST/EST throwing). +- Changed the single `ZoneId.of(session.getTimeZone())` → `ZoneId.of(session.getTimeZone(), SESSION_TIME_ZONE_ALIASES)`. +- Rewrote the method javadoc: removed the "KNOWN LIMITATION / CST·PST·EST fail-loud" framing; now states it resolves byte-identically to legacy `TimeUtils.getTimeZone()` and fail-loud fires only for ids absent from BOTH ZoneId.of's native set AND the map. Error message unchanged (still contains "standard"/"zone id"). + +## Tests (`PaimonConnectorMetadataMvccTest`) +- **Repurposed** `resolveTimestampStringWithUnsupportedZoneAliasThrowsClearError` → `resolveTimestampStringWithGenuinelyUnknownZoneFailsLoud` (input `"CST"`→`"XYZ"`; same DorisConnectorException + "standard"/"zone id" assertions — intent "fail loud on unknown" preserved). +- **Added** `resolveTimestampStringResolvesCstAliasToShanghai` (CST→Asia/Shanghai byte-parity) and `resolveTimestampStringResolvesPstAndEstViaShortIds` (PST→America/Los_Angeles, EST→-05:00 — the report-suggestion correction guard). + +## Deviation from design (Rule 9, documented) +The design said "keep `resolveTimestampDigitalUnaffectedByUnsupportedZoneAlias` as-is". I changed its session zone `"CST"`→`"XYZ"`. Rationale: after the fix CST RESOLVES, so a CST session would no longer prove the digital-bypass (the string path would parse fine too) — the test would pass even if someone removed the `spec.isDigital()` short-circuit, losing its mutation-catching power. `"XYZ"` still throws on the string path, so the test keeps discriminating. This is a faithful improvement, not a scope change. + +## Live-e2e (gated, NOT run): `SET time_zone='CST'/'PST'/'EST'; SELECT ...

From 77d4ed44d10e2e7b6a3732c56b181e4bc0ff8226 Mon Sep 17 00:00:00 2001 From: morningman Date: Thu, 11 Jun 2026 13:05:35 +0800 Subject: [PATCH 015/128] =?UTF-8?q?fix:=20FIX-URI-NORMALIZE=20=E2=80=94=20?= =?UTF-8?q?normalize=20native=20data-file=20+=20DV=20paths=20to=20BE=20can?= =?UTF-8?q?onical=20scheme?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: the paimon connector sent native ORC/Parquet data-file paths and deletion-vector (DV) paths to BE un-normalized. The paimon SDK emits warehouse-native schemes (oss://, cos://, obs://, s3a://, or the OSS bucket.endpoint authority form); BE's scheme-dispatched S3 file factory only recognizes s3://. On S3-compatible (non-AWS) warehouses this breaks native reads outright (B-7DF, data file) and silently drops the DV so DELETEd rows reappear (B-7DV, merge-on-read corruption). Legacy PaimonScanNode normalized both via the 2-arg LocationPath.of; the cutover dropped it. The two paths reach BE via different mechanisms (data-file through PluginDrivenSplit's single-arg LocationPath.of -> FileQueryScanNode:568; DV baked into thrift by the connector's populateRangeParams), so a fe-core-bridge-only fix cannot reach the DV path. Solution: new ConnectorContext.normalizeStorageUri SPI hook (identity default, mirroring vendStorageCredentials), implemented in DefaultConnectorContext via the engine's 2-arg normalizing LocationPath.of with the catalog's static storage map (threaded via a new lazy supplier + 4-arg ctor; PluginDrivenExternalCatalog wires it). The connector routes BOTH the data-file and DV paths through it inside the extracted, unit-testable buildNativeRange. JNI path untouched (carries its own FileIO). Fail-loud on un-normalizable paths (legacy parity). Static-vs-vended map scope noted in DV-025 (the pure-vended edge belongs to credential fixes #2/#3). Tests: fe-core DefaultConnectorContextNormalizeUriTest (oss->s3, s3 idempotent, null/blank, empty-map fail-loud); connector PaimonScanPlanProviderTest x3 (both paths normalized + call count, DV-less, no-context raw). paimon module 216/0/0, fe-core targeted green, checkstyle 0, import-gate clean. Live OSS+DV e2e CI-gated (not run). SPI RFC section 21 (E13), deviations DV-025. Also includes the round-2 review report + task list this fix derives from.

But the *asserted observable* — + `ExternalUtil.getExternalSchema(root.setId(column.getUniqueId()))` — is **not reachable at + HEAD** for a cutover paimon table for three independent reasons: + 1. **Dead path for cutover.** The only paimon caller of `ExternalUtil.initSchemaInfo` is the + legacy `PaimonScanNode:169`. A cutover paimon table routes via + `PhysicalPlanTranslator.java:737` to `PluginDrivenScanNode`, which returns `FORMAT_JNI`, + never calls `initSchemaInfo`, and never references `getUniqueId` (grep: zero hits). + 2. **`getUniqueId()` was never the BE field-id channel even in legacy.** Line 169 passes + `schemaId=-1` with a TODO; the per-schema field-id the BE native reader actually consumes + flows through `PaimonScanNode.putHistorySchemaInfo` → `PaimonUtil.getSchemaInfo` → + `childField.setId(paimonField.id())` (`PaimonUtil.java:415`), read straight from the + paimon `DataField`, **not** from `Column.getUniqueId()`. So the claim mislocates the + channel. + 3. **No live FE consumer surfaces it.** DESCRIBE/SHOW COLUMNS render + name/type/comment/nullable, not `uniqueId`; the only external-table consumer of + `getUniqueId()` is the dead `ExternalUtil` path. + + The genuine BE field-id concern belongs to the separately-confirmed BLOCKER (B2 family, + connector scan-side `history_schema_info`), a different code path.

Per-Path Parity Summaries (13 paths) + +**Path #1 — Basic read (normal scan): NOT at parity.** Core per-type partition rendering, +predicate literal conversion, JNI/native/cpp split-format selection, table-location, +self-split-weight, serialized-table, predicate push, and session-timezone source are all +byte-faithful and match. But the connector does not run old logic and in doing so DROPS +several legacy fe-core semantics: most seriously the entire schema-evolution mechanism +(BLOCKER B-1a), plus `force_jni_scanner`/`ignore_split_type` controls, storage-path scheme +normalization, FE-side COUNT(\*) pushdown, and FE-side sub-file splitting. One BLOCKER + four +MAJORs. + +**Path #2 — Batch incremental read (@incr): CLEAN.** `PaimonIncrementalScanParams.validate` +is a byte-faithful port of legacy `validateIncrementalReadParams` (only signature, cosmetic +wrapping, and three benign stripped null-resets differ). All three legacy guards reproduced; +the stripped null-resets are verified benign because the connector's base table is never +pre-pinned. No BLOCKER/MAJOR; two NIT/MINOR that do not change results. + +**Path #3 — Time Travel (FOR TIME/VERSION AS OF): CLEAN.** Cutover is real end-to-end; legacy +`PaimonExternalTable.getPaimonSnapshotCacheValue` is unreachable. All five spec kinds map +byte-faithfully; session-TZ datetime parse replicates `TimeUtils` byte-for-byte; +schema-at-snapshot resolves the historical schema + partition keys exactly. Only divergences +are documented, text-only/effect-noop. No BLOCKER/MAJOR. + +**Path #4 — Branch / Tag read: CLEAN (no data-loss/wrong-rows).** Cleanly cutover; TAG read is +byte-parity; BRANCH read is functionally correct and matches legacy at the data level. The +only real divergences are in branch SCHEMA-version resolution under independent branch schema +evolution (connector reads the branch's own `schemaManager`/snapshot schema — arguably MORE +correct than legacy) plus three text-only error-message divergences. No BLOCKER/MAJOR. + +**Path #5 — System tables: CLEAN.** Legacy sys path is DEAD for cutover catalogs and does not +fall back. The connector reimplementation is a near-exact parity port: +`listSupportedSysTables`, `getSysTableHandle` (same 4-arg identifier, same case-insensitive +check, same `forceJni={binlog,audit_log}` rule), the HIVE_TABLE descriptor, privilege unwrap, +and SHOW CREATE TABLE unwrap all match. Only divergence: `getSupportedSysTables()` now needs a +live remote handle resolution (MINOR). + +**Path #6 — Metadata cache: CLEAN (perf/architectural only).** The cutover intentionally swaps +the legacy 3-level paimon cache for the generic schema-only cache + per-query live metadata, +and does so correctly. No live control flow back into `datasource/paimon/*`; GSON compat +revives old catalogs/dbs/tables as PluginDriven variants. REFRESH TABLE/CATALOG/DB and ALTER +CATALOG SET PROPERTIES all reach correct invalidation; partition-name rendering and +`isPartitionInvalid` are byte-parity. Divergences are perf/architectural, not correctness — +no wrong-rows, no lost invalidation, no stale-cache hazard. + +**Path #7 — Deletion Vector read: NOT at parity (BLOCKER).** DV assembly STRUCTURE +(native-vs-JNI routing, per-i DV pairing, `selfSplitWeight` accounting, BE thrift wire format) +is faithful. But the connector drops the legacy URI normalization on BOTH the deletion-file +path AND the native data-file path — feeding BE unrecognized `oss://`/`cos://`/`obs://`/`s3a://` +schemes. Two BLOCKERs (B-7DV deletion-file, B-7DF data-file). Pure-`s3://`/`hdfs://` tables are +unaffected. One MINOR (EXPLAIN delete-file accounting). + +**Path #8 — Multi metadata-service (flavor assembly): NOT at parity.** Paimon is LIVE. Most +flavor logic matches and HMS Kerberos auth survives. But two BLOCKERs (JDBC raw/unresolved +`driver_url` + dropped alias → `MalformedURLException`; JDBC driver_url security validation +bypassed → arbitrary remote jar in FE JVM) and one MAJOR (filesystem/jdbc over Kerberized HDFS +lose UGI `doAs` because `initializeCatalog` is dead on the cutover path). The in-code +"not in SPI_READY_TYPES" disclaimer is stale. + +**Path #9 — Multi storage-system access: NOT at parity (BLOCKER).** Two sub-paths. (1) Vended +REST credentials: faithful — reuses the EXACT legacy normalization tail, byte-equivalent AWS_* +keys. CLEAN. (2) STATIC (non-vended) S3/OSS/COS/OBS credential downflow is BROKEN: connector +copies RAW catalog keys verbatim under `location.*` with no normalization, so BE's native +reader never sees recognized `AWS_*` credentials (BLOCKER B-9). Verified against the +connector's own test that codifies the raw key. Two MINORs (HDFS derived defaults dropped; +FE-only `hive.*` keys leaked to BE). + +**Path #10 — Column type mapping: NOT at parity.** WRITE direction (Doris→Paimon) is a +faithful port. READ direction is mostly faithful but drops three column-level legacy semantics +(`uniqueId`/field-id, all-columns `isKey=true`, `WITH_TIMEZONE` extraInfo). The field-id loss +is the serious one (MAJOR M-10, root cause of the BE schema-evolution BLOCKER). WRITE also +silently drops nested struct-field comments. The standalone `getUniqueId()` repro was refuted +(§4); the real impact rides on B2. + +**Path #11 — MTMV (materialized view): NOT at parity (MAJOR).** MTMV path is LIVE on the +connector; legacy `PaimonExternalTable` is dead baseline. Partition listing/name rendering, +`PartitionItem` build, `isPartitionInvalid`, MTMV snapshots, and the three consumers all map +1:1 to legacy. The one substantive divergence: legacy wrapped partition listing in the +Kerberos authenticator (UGI `doAs`); the connector read path does NOT (MAJOR M-11, scoped to +secured HMS deployments; the "DLF" clause is overstated). + +**Path #12 — MVCC (MvccSnapshot): CLEAN.** Faithfully migrated and LIVE. The three MVCC SPI +methods reproduce legacy `getPaimonSnapshotCacheValue` and PaimonUtil resolution exactly +(query-begin pins latest, explicit time-travel pins `scan.snapshot-id`/`scan.tag-name`, @incr +ports validation byte-for-byte, @branch loads the branch table via a 3-arg Identifier). The +scan-side pin is correct at all three handle-consumption sites; the pinned table is serialized +to BE identically to legacy. No fallback, no shadow class, no swallowing no-op, no +serialization mismatch. Two narrow, documented, benign MINOR/NIT divergences. + +**Path #13 — Cross-cutting fallback enumeration: see §8.** Cutover is active; legacy +`datasource/paimon/*` is dead-but-in-tree and NONE are reached on the connector path. Every +fe-core consumer that still imports/instanceof's legacy paimon is ordered or gated so the +PluginDriven branch wins and preserves legacy semantics. The serious divergences are NOT +fallbacks into old logic but LOST legacy semantics on the BE serialization contract (schema +evolution + `force_jni_scanner`/`ignore_split_type`). One BLOCKER + one MAJOR + one MINOR. + +--- + +## 7. Completeness Critic + +### Coverage gaps surfaced (warrant a follow-up pass) + +1. **DDL operations (CREATE/DROP TABLE, CREATE/DROP DATABASE) and ALTER TABLE + CREATE/DROP BRANCH/TAG.** None of the 13 paths traced `PaimonConnectorMetadata` + `createTable`/`dropTable`/`createDatabase`/`dropDatabase` + (`PaimonConnectorMetadata.java:683-797`) against legacy `PaimonMetadataOps` end-to-end. + Branch/tag READ was covered (path #4) but branch/tag DDL WRITE + (`ExternalCatalog.java:1427-1513`) was not. **Follow-up:** trace IF-NOT-EXISTS/IF-EXISTS + short-circuit, editlog/cache-refresh ordering, and error-code parity + (`ERR_DB_CREATE_EXISTS` vs `DorisConnectorException`) on stale FE cache. +2. **Read-direction type-mapping catalog flags** (`enable.mapping.varbinary` / + `enable.mapping.timestamp_tz`).

FIX-URI-NORMALIZE — native data-file + DV paths sent to BE un-normalized +- **Findings**: B-7DF (data file), B-7DV (deletion vector). Failure: native ORC/Parquet + DV reads **fail outright** on `oss://`/`cos://`/`obs://`/`s3a://` warehouses (BE S3 factory only recognizes `s3://`). Pure `s3://`/`hdfs://` unaffected. +- **Connector**: `PaimonScanPlanProvider.java:269-276` (`.path(file.path())` raw), `:281-283` (`builder.deletionFile(df.path(),…)` raw); `PaimonScanRange.java:190-200`. +- **fe-core**: `PluginDrivenSplit.java:65-68` (single-arg, NON-normalizing `LocationPath.of`); `PluginDrivenScanNode`. +- **Legacy parity**: `source/PaimonScanNode.java:295-298` (DV) and `:443` (data file) — both use the **2-arg** `LocationPath.of(path, storagePropertiesMap).toStorageLocation()`. +- **Fix sketch**: connector can't import `LocationPath` → normalize in the fe-core bridge (`PluginDrivenSplit.buildPath` + the DV desc build in `PluginDrivenScanNode`/`PaimonScanRange`) using the storage-properties map, **or** add a `ConnectorContext` path-normalization SPI hook (mirror the `FIX-REST-VENDED` seam). Apply to **both** the data-file path and the DV path. +- **Test**: connector/bridge UT asserting an `oss://` input → `s3://` BE-bound path for both data + DV; live-e2e (OSS warehouse + DV) is CI-gated. + +### 2. FIX-STATIC-CREDS-BE — static object-store creds reach BE as RAW keys +- **Finding**: B-9. Static `s3.*`/`oss.*`/`cos.*`/`obs.*` catalog creds are copied verbatim under `location.`; BE native reader wants `AWS_ACCESS_KEY`/`AWS_SECRET_KEY`/… → no usable creds → 403 on private buckets. (FIX-REST-VENDED fixed the *vended* seam; FIX-STORAGE-CREDS fixed the *catalog FileIO* seam — this is the **third, static→BE-scan seam**, see review §9.3.) +- **Connector**: `PaimonScanPlanProvider.java:347-356` (`getScanNodeProperties`, raw copy under `location.*`). +- **fe-core**: `PluginDrivenScanNode.java:307-320` (`getLocationProperties` only strips the `location.` prefix — no normalization). +- **Legacy parity**: `source/PaimonScanNode.java:176,650-652`; `AbstractS3CompatibleProperties.java:105-122` (canonical alias → `AWS_*`); BE `s3_util.cpp:146-150`. +- **Fix sketch**: normalize static aliases to BE `AWS_*` before they leave FE — reuse / extend the `ConnectorContext.vendStorageCredentials` normalization tail for static keys, or normalize in the bridge. Also covers the bare `AWS_*`/`access_key` (no `s3.` prefix) case currently dropped entirely. +- **Test**: UT mutating the connector test that currently codifies the raw key (`PaimonScanPlanProviderTest.java:535`) → assert BE-bound `AWS_ACCESS_KEY` present; live-e2e CI-gated (private S3/OSS). + +### 3. FIX-SCHEMA-EVOLUTION — native reader loses paimon schema-evolution (+ field-id) +- **Findings**: B-1a (BLOCKER, silent wrong/NULL rows on column rename/reorder via native reader) + M-10 (MAJOR, `Column.uniqueId` left -1 — its root cause; standalone repro refuted but it feeds B-1a's BE contract). +- **Connector**: `PaimonScanRange.java:181-184` (only sets per-file `schema_id`); `PaimonScanPlanProvider.java:276`; `PaimonConnectorMetadata.java:1007-1012` (5-arg `ConnectorColumn`, no field-id); `ConnectorColumnConverter.java:65-70` (→ `uniqueId=-1`). +- **fe-core**: `PluginDrivenScanNode` never calls `ExternalUtil.initSchemaInfo` / sets `current_schema_id` / `history_schema_info`. +- **Legacy parity**: `source/PaimonScanNode.java:169` (`initSchemaInfo(-1L)`), `:285` (`putHistorySchemaInfo` per native split); `ExternalUtil.java:86-92`; `PaimonUtil.getHistorySchemaInfo`; `PaimonExternalTable.java:349-355` + `PaimonUtil.java:318-347` (recursive `updatePaimonColumnUniqueId`, incl. nested ARRAY/MAP/ROW). +- **BE contract (frozen)**: `be/src/format/table/table_schema_change_helper.h:219-236` falls back to `by_parquet_name`/`by_orc_name` when `history_schema_info` is unset; field-id path is `:241-267`. +- **Fix sketch**: (a) thread paimon `DataField.id()` through SPI `ConnectorColumn` (+ nested) → `Column.setUniqueId`; (b) emit `current_schema_id` + per-split `history_schema_info` on the native path via the bridge (`PluginDrivenScanNode` → `ExternalUtil.initSchemaInfo` + per-split schema). Largest SPI surface of the P0 set. +- **Test**: UT asserting the native split params carry `current_schema_id` + history schema; e2e = `test_paimon_full_schema_change.groovy` (rename over ORC/Parquet) CI-gated. + +### 4. FIX-JDBC-DRIVER-URL — JDBC flavor driver_url unresolved + unvalidated +- **Findings**: B-8a (raw unresolved `jdbc.driver_url` + dropped `paimon.jdbc.*` alias → `MalformedURLException`) + B-8b (security allow-list / format / secure-path not enforced → arbitrary remote jar in FE JVM; stale "not in SPI_READY_TYPES" disclaimer). +- **Connector**: `PaimonScanPlanProvider.java:549-565` (forwards `jdbc.*` verbatim); `PaimonConnector.java:232-247,206-216,249-287` (`resolveFullDriverUrl` — no validation); `:230` (stale disclaimer). +- **Legacy parity**: `PaimonJdbcMetaStoreProperties.java:164-176` (emits `jdbc.driver_url=getFullDriverUrl(resolved)`), `:190`; `JdbcResource.java:300-329` (format + `checkCloudWhiteList` + `jdbc_driver_secure_path`). +- **Fix sketch**: resolve `driver_url` via `getFullDriverUrl` on the BE-options path + honor the `paimon.jdbc.*` alias (B-8a); enforce the FE security allow-list/format/secure-path — the wired hook is `ConnectorValidationContext.validateAndResolveDriverPath` (jdbc/trino override `preCreateValidation`); paimon must override it (B-8b). Remove the stale disclaimer. +- **Severity note (cross-check)**: round-1 rated the *security* facet PARTIAL ("default `jdbc_driver_secure_path="*"` → legacy also loads any jar"). B-8a (functional `MalformedURLException`) is unambiguous; for B-8b confirm whether to treat as BLOCKER or hardened-config-only — **fold both into one fix regardless.** + +--- + +## P1 — MAJOR (fix or explicitly accept) + +### 5. FIX-MAPPING-FLAG-KEYS — type-mapping flags silently dead (wrong column types) +- **Finding**: M-crit (critic-surfaced; **not 3-lens-gated → re-verify first**). Connector reads underscore keys `enable_mapping_binary_as_varbinary` / `enable_mapping_timestamp_tz`; FE/legacy set DOTTED keys `enable.mapping.varbinary` / `enable.mapping.timestamp_tz` → flags stuck false → BINARY→STRING and LTZ→DATETIMEV2 even when the user enabled the mapping. +- **Connector**: `PaimonConnectorProperties.java:39,42`; read `PaimonConnectorMetadata.java:1017-1027`; consumed `PaimonTypeMapping.java:130-165`. **Legacy**: `CatalogProperty.java:50,52`; `ExternalCatalog.setDefaultPropsIfMissing:302-306`; `PaimonUtil.paimonPrimitiveTypeToDorisType:253,257,283-286`. +- **Fix sketch**: read the dotted keys the FE actually sets (and reconcile the renamed `varbinary` key), or normalize dots→underscores in `PluginDrivenExternalCatalog.createConnectorFromProperties` before constructing the connector. Pure connector/FE-wiring; no BE. +- **Test**: UT constructing the connector with `{"enable.mapping.timestamp_tz":"true"}` → assert LTZ column maps to TIMESTAMPTZ (closes critic coverage-gap #2). + +### 6. FIX-KERBEROS-DOAS — UGI doAs lost on fs/jdbc ops + partition listing +- **Findings**: M-8 (filesystem/jdbc over Kerberized HDFS lose `doAs` — `initializeCatalog` dead on cutover path; HMS unaffected) + M-11 (MTMV / SHOW PARTITIONS / partitions-TVF partition listing runs the `listPartitions` RPC without `doAs` on Kerberos HMS). Grouped: same authenticator mechanism. +- **Connector**: `PaimonConnector.java:124-196` (M-8); `PaimonCatalogOps.java:249-251`, `PaimonConnectorMetadata.java:892-894` (M-11). **fe-core**: `PluginDrivenExternalCatalog.java:122-137,150`; `PluginDrivenMvccExternalTable.java:157`; `PluginDrivenExternalTable.java:317-318`. +- **Legacy parity**: `PaimonFileSystemMetaStoreProperties.java:40-57`, `PaimonJdbcMetaStoreProperties.java:111-135` (M-8); `PaimonExternalCatalog.java:96-118` (`executionAuthenticator.execute` wrap), `metacache/paimon/PaimonPartitionInfoLoader.java:49` (M-11). +- **Fix sketch**: wire the fs/jdbc HDFS authenticator on the live (connector) create path; wrap the partition-listing read RPC in `executeAuthenticated` (note round-1 D7=B deliberately left read-vs-DDL asymmetric — confirm whether to wrap reads too). Scope = secured HMS/HDFS deployments. **Verify the M-8 "DLF" clause** (review says it's overstated; DLF inherits the no-op authenticator). + +### 7. FIX-FORCE-JNI-SCANNER — `force_jni_scanner` session var ignored +- **Finding**: M-1. Connector reads only `paimonHandle.isForceJni()` (binlog/audit flag), never the session `force_jni_scanner`; native always chosen for ORC/Parquet. The JNI escape hatch (used to dodge native-reader bugs — incl. the B2 schema-evolution one) is gone. +- **Connector**: `PaimonScanPlanProvider.java:261,439-441` (`shouldUseNativeReader`). **Legacy**: `source/PaimonScanNode.java:361,430` (`sessionVariable.isForceJniScanner()` gate). +- **Fix sketch**: read `force_jni_scanner` from the session-properties map (the var is already in it — connector reads sibling `enable_paimon_cpp_reader` from there) and route all data splits to JNI when set. Pure connector. + +--- + +## P2 — Severity-disputed MAJOR (perf-parity; round-1 = MINOR) — **user decides scope** + +> Both are correct-results, perf/parallelism-only. Recommend **accept-or-defer** unless perf parity is required for cutover. If deferring, log in `deviations-log.md`. + +### 8. FIX-COUNT-PUSHDOWN — `COUNT(*)` pushdown not implemented (M-2) +- Connector never computes `mergedRowCount` / emits `paimon.row_count` → BE materializes merged rows to count (esp. costly on PK tables). `PaimonScanPlanProvider.java:186-296` vs `source/PaimonScanNode.java:396,421-429,483-495`. + +### 9. FIX-NATIVE-SUBSPLIT — native sub-file splitting lost (M-3) +- One split per RawFile; large ORC/Parquet files get a single scanner. `PaimonScanPlanProvider.java:263-286` vs `source/PaimonScanNode.java:434-465` (`determineTargetFileSplitSize` + `fileSplitter.splitFile`). See also critic coverage-gap on split-count accounting (P3). + +--- + +## P3 — Coverage gaps to verify/close (completeness critic; NOT confirmed bugs) + +> These are "go check", not fixes.

Confirm it reaches `getScanNodeProperties` for HMS/DLF. +- **TRACE DDL write parity**: `PaimonConnectorMetadata.createTable/dropTable/createDatabase/dropDatabase` (`:683-797`) vs legacy `PaimonMetadataOps`; branch/tag DDL write (`ExternalCatalog.java:1427-1513`); IF-(NOT-)EXISTS short-circuit, editlog/cache-refresh ordering, error-code parity. +- **TRACE ANALYZE / column-stats**: `ExternalAnalysisTask` / `getColumnStatistic` parity (fetchRowCount itself already confirmed faithful). +- **CHECK split-count accounting** under lost splitting (`SqlBlockRuleMgr` limits, batch-mode) — ties to #9. + +--- + +## P4 — MINOR / NIT (low-priority cleanup; full list in review §5) + +Bundle as one optional cleanup pass after P0–P1. Most are display-only (DESC `Key`/`Extra`/`uniqueId`, VARCHAR(65533)→STRING, EXPLAIN delete-split accounting, error-message text), perf/architectural (cache granularity), or benign. **The one with a real (rare) data edge**, worth a deliberate decision: +- Partition null-sentinel coercion: a STRING partition whose literal value is `__HIVE_DEFAULT_PARTITION__` or `\N` is coerced to NULL (connector) vs read as the literal (legacy). `PaimonScanRange.java:212-225` / `ConnectorPartitionValues.java:32-54` vs `source/PaimonScanNode.java:323-326`. + +--- + +## Notes / gates (reuse) +- maven: absolute `-f /mnt/disk1/yy/git/wt-catalog-spi/fe/pom.xml -pl : -am -Dmaven.build.cache.enabled=false -DfailIfNoTests=false`; verify via surefire XML + `MVN_EXIT`. `-pl :fe-connector-paimon -am` does **not** rebuild fe-core; fe-core changes need `-pl :fe-core -am`. +- Connector import gate: `bash tools/check-connector-imports.sh` (must stay clean — drives the "SPI?" column: B1/B3/B2 need fe-core-side or new `ConnectorContext` SPI seams because the connector can't import `LocationPath`/`StorageProperties`). +- cwd persists across Bash calls; `cd` breaks relative paths → always absolute. +- Tests: prefer runnable FE **unit tests** (connector harness: `FakePaimonTable` / `RecordingPaimonCatalogOps` / `RecordingConnectorContext` / `PaimonScanPlanProviderTest`).

Line numbers below are CURRENT. + +## Problem + +The paimon connector sends native ORC/Parquet **data-file** paths and **deletion-vector (DV)** paths to BE **without URI scheme normalization**. The paimon SDK emits paths in the warehouse's native scheme (`oss://`, `cos://`, `obs://`, `s3a://`, or the OSS `bucket.endpoint` authority form). BE's file factory is **scheme-dispatched** and its S3 reader only recognizes canonical `s3://`. Result on any S3-compatible (non-AWS) warehouse: + +- **B-7DF (data-file)**: native ORC/Parquet read **fails outright** — `S3URI::parse` rejects `oss://…`. +- **B-7DV (deletion-vector)**: BE cannot open the DV index → **deleted rows silently reappear** (merge-on-read corruption — the more dangerous failure: wrong rows, not a hard error). + +Pure `s3://` / `hdfs://` warehouses are unaffected (their scheme is already canonical). JNI read path is unaffected (the serialized paimon `Table` carries its own `FileIO`). + +## Root Cause + +Legacy `PaimonScanNode` normalizes **both** paths through the **2-arg normalizing** factory `LocationPath.of(path, storagePropertiesMap)` → `StorageProperties.validateAndNormalizeUri()` (e.g. `OSSProperties.validateAndNormalizeUri` rewrites `oss://bucket.endpoint/p` → `oss://bucket/p`, then the S3-compatible base rewrites scheme → `s3://`): +- data-file: `datasource/paimon/source/PaimonScanNode.java:443` +- DV: `…/PaimonScanNode.java:296-297` (`…toStorageLocation().toString()`) + +The cutover dropped this. The two paths now reach BE raw via **two structurally different mechanisms**: + +1. **Data-file path** (3-hop chain, all raw): + - `PaimonScanPlanProvider.java:270` — `.path(file.path())` stores the raw paimon-SDK path into `PaimonScanRange`. + - `PluginDrivenSplit.java:65-68` — `buildPath()` calls the **single-arg** `LocationPath.of(pathStr)` (`LocationPath.java:163-169`), which sets `normalizedLocation = location` verbatim, `storageProperties = null` — **no normalization**. + - `FileQueryScanNode.java:568` — `rangeDesc.setPath(fileSplit.getPath().toStorageLocation().toString())`; `toStorageLocation()` (`LocationPath.java:404`) wraps the raw `normalizedLocation`. **This is the only writer of the data-file path to BE thrift.** + +2. **DV path** (connector-baked into thrift): + - `PaimonScanPlanProvider.java:282` — `builder.deletionFile(df.path(), …)` stores the raw DV path. + - `PaimonScanRange.java:194` — `deletionFile.setPath(deletionPath)` writes it straight into `TPaimonDeletionFileDesc`, **inside the connector's `populateRangeParams`**, which fe-core invokes opaquely (`PluginDrivenScanNode.java:762`). **fe-core never sees the DV path as a separable value.** + +The connector **cannot** import fe-core's `LocationPath` / `StorageProperties` (SPI boundary, enforced by `tools/check-connector-imports.sh`). + +## Design + +**A new `ConnectorContext` SPI normalization hook, called by the connector at both raw sites.** This is the only seam that fixes **both** paths with one uniform mechanism. A fe-core-bridge-only fix (normalize in `PluginDrivenSplit.buildPath`) is **impossible for the DV path** — the connector bakes it into thrift before fe-core can intercept it. Mixing two mechanisms (bridge for data-file, SPI for DV) would be inconsistent; the SPI hook covers both and keeps format-specific thrift construction in the connector (the established design, `PluginDrivenScanNode.java:761`). This mirrors the existing `ConnectorContext.vendStorageCredentials` credential seam (the task-list's recommended pattern) exactly. + +### SPI (`fe-connector-spi/ConnectorContext.java`) — new default no-op method +```java +/** Normalizes a raw storage URI a connector emits (e.g. paimon native data-file / DV path like + * oss://…, cos://…, s3a://…) to BE's canonical form (s3://…) using the catalog's storage + * properties.

New 4-arg ctor; the existing 2-arg/3-arg ctors delegate with a `Collections::emptyMap` supplier (identity-preserving for non-plugin catalogs — `LocationPath.of(x, {})` would throw, but those ctors are never used by paimon and the method is only called by paimon). + +### catalog wiring (`PluginDrivenExternalCatalog.java:150`) +```java +new DefaultConnectorContext(name, id, this::getExecutionAuthenticator, + () -> catalogProperty.getStoragePropertiesMap()) +``` + +### connector call sites (`PaimonScanPlanProvider.java`, native-reader branch only) +- `:270` → `.path(normalizeUri(file.path()))` +- `:282` → `builder.deletionFile(normalizeUri(df.path()), df.offset(), df.length())` +- private helper `normalizeUri(String raw)` = `context != null ? context.normalizeStorageUri(raw) : raw` (null-guard mirrors the existing `vendStorageCredentials` guard at `:363` for the offline unit-test path). + +JNI path (`buildJniScanRange`) and `getScanNodeProperties` are **not** touched (JNI carries its own FileIO; credential keys are a separate fix #2). + +## Implementation Plan +1. `ConnectorContext.java`: add `normalizeStorageUri` default method. +2. `DefaultConnectorContext.java`: add `storagePropertiesSupplier` field + 4-arg ctor (existing ctors delegate with empty-map supplier) + `normalizeStorageUri` override + `LocationPath` import. +3. `PluginDrivenExternalCatalog.java:150`: pass the storage-props supplier. +4. `PaimonScanPlanProvider.java`: add `normalizeUri` helper; apply at `:270` and `:282`. +5. Tests (below). Build `:fe-core -am` (SPI+fe-core) then `:fe-connector-paimon -am`. +6. `tools/check-connector-imports.sh` must stay clean (no new fe-core import in connector). + +## Risk Analysis +- **Regression on s3:// / hdfs:// (common path)**: `normalizeStorageUri` now runs on every native path. For an `s3://`/`hdfs://` warehouse, `getStoragePropertiesMap()` contains the matching type → `validateAndNormalizeUri` is a no-op/idempotent → same `s3://`/`hdfs://` reaches BE. Legacy uses the identical 2-arg `of()`, so parity holds. Verified: the catalog's storage type == the warehouse scheme, so the map always has the entry for a working catalog. +- **Fail-loud**: matches legacy (2-arg `of()` throws `StoragePropertiesException` on missing props). A wrong/un-normalizable path → loud failure instead of silent BE corruption (Rule 12). +- **Vended-vs-static map (scope note)**: legacy overlays vended creds via `VendedCredentialsFactory.getStoragePropertiesMapWithVendedCredentials`; this fix uses the **static** `getStoragePropertiesMap()`. For **scheme** normalization the vended overlay is irrelevant (vended creds change `AWS_*` keys, not the scheme/bucket form) **as long as the warehouse endpoint is statically configured** (the overwhelmingly common case for OSS/COS/OBS — you need the endpoint to connect). The only divergence is a *pure-vended, no-static-storage-config* REST catalog, where `getStoragePropertiesMap()` may lack the entry and normalization throws. That edge overlaps the credential seam fixes (#2 `FIX-STATIC-CREDS-BE` / `FIX-REST-VENDED`) and is **explicitly out of scope** here; tracked in `deviations-log.md`. +- **Other connectors**: SPI method has an identity default; only paimon calls it. Zero impact on es/jdbc/maxcompute/trino. + +## Test Plan + +### Unit Tests +1. **`DefaultConnectorContextNormalizeUriTest` (fe-core)** — construct `DefaultConnectorContext` with a real OSS `StorageProperties` map (built from `oss.endpoint`/`oss.access_key`/… via `StorageProperties.createAll`), assert `normalizeStorageUri("oss://bkt/warehouse/f.parquet")` → `s3://…`. Assert identity for `s3://…` input. Assert empty-map supplier ctor + non-normalizable input behavior (fail-loud). *Encodes WHY: BE only opens canonical scheme; mutation = returning raw oss:// → red.* +2. **`PaimonScanPlanProviderTest` (connector) — wiring** — extend `RecordingConnectorContext` with a `normalizeStorageUri` override that records the call and applies a deterministic `oss://`→`s3://` rewrite. Build a native `DataSplit` (RawFile + DeletionFile with `oss://` paths) through `planScan`; assert the resulting `PaimonScanRange` carries **both** the normalized data-file path (via `getPath()`) **and** the normalized DV path (via `getProperties().get("paimon.deletion_file.path")`). Assert the offline no-context path still emits raw (preserves existing offline behavior). *Encodes WHY: both raw sites must route through the hook; mutation = dropping either call site → red on that path.* + +### E2E Tests (CI-gated — note, do not claim run) +- `test_paimon_*` deletion-vector + native-read suites over an **OSS** warehouse (DELETE then SELECT; assert deleted rows stay deleted and native ORC/Parquet rows return).

The paimon connector copied static catalog-level storage credentials/config verbatim into the BE scan-node properties: PaimonScanPlanProvider.getScanNodeProperties iterated the raw catalog properties and emitted location. for any s3./oss./cos./obs./ hadoop./fs./dfs./hive. prefix; the fe-core bridge only strips the location. prefix. BE's native (FILE_S3) reader understands ONLY AWS_ACCESS_KEY/ AWS_SECRET_KEY/AWS_ENDPOINT/AWS_REGION/AWS_TOKEN, so static s3.access_key/ oss.access_key on a private bucket reached BE unintelligible -> no usable credentials -> 403. This is the third credential seam (static->BE-scan), missed by both the prior round and the 8 fixes (review §9.3); the catalog- FileIO seam (FIX-STORAGE-CREDS) and the vended seam (FIX-REST-VENDED) were already closed. Root cause: legacy PaimonScanNode.getLocationProperties returns only CredentialUtils.getBackendPropertiesFromStorageMap(storagePropertiesMap) (the canonical AWS_*/hadoop/dfs map). The cutover replaced that single normalized call with a raw prefix-copy loop; the connector cannot import fe-core's StorageProperties so it had no access to the normalization. Solution (D-048, user-signed full legacy-parity scope): new no-op-default SPI ConnectorContext.getBackendStorageProperties(); DefaultConnectorContext returns getBackendPropertiesFromStorageMap over the storagePropertiesSupplier already wired in FIX-URI-NORMALIZE (no ctor change, CredentialUtils already imported). The connector replaces its raw prefix-copy loop with a context-gated overlay of that map; the vended overlay stays after it (vended wins on collision, legacy precedence). Object-store creds -> AWS_*; HDFS -> canonical hadoop/dfs (preserves user overrides + adds the legacy defaults, folding in the §211 MINOR); drops the non-parity hive.* passthrough. Investigated the AWS_CREDENTIALS_PROVIDER_TYPE=ANONYMOUS two-step edge and confirmed via BE s3_util.cpp (both providers prefer explicit ak/sk over cred_provider_type) that it is harmless — no regression. Connector import-gate stays clean. Tests: fe-core DefaultConnectorContextBackendStoragePropsTest (OSS static creds -> AWS_*, raw alias absent; no-supplier -> empty); connector PaimonScanPlanProviderTest (+getScanNodePropertiesNormalizesStaticCreds raw alias not shipped; modified vended-overlay collision to canonical keys; renamed no-context test -> emits no storage props). Fail-before/pass-after proven by reverting the connector change (2/3 go red). Module 217/0/0 (1 CI-gated skip), checkstyle clean, import-gate clean. Live private-bucket native-read e2e is CI-gated (not run). SPI RFC §22 (E14).

The bare `AWS_*` / `access_key` form (no `s3.` prefix) is dropped entirely by the prefix filter. + +This is distinct from the two credential seams already fixed: +- **FIX-STORAGE-CREDS** fixed the *catalog FileIO* seam (canonical → `fs.s3a.*` for paimon's own metadata reads). +- **FIX-REST-VENDED** fixed the *vended (REST) scan→BE* seam (`ConnectorContext.vendStorageCredentials`). +- **This (B-9)** is the *static catalog creds → BE scan* seam — review §9.3, seam #3. + +## Root Cause + +Legacy `PaimonScanNode.getLocationProperties:650-652` returns **only** `backendStorageProperties`, computed at `:176` as: +```java +backendStorageProperties = CredentialUtils.getBackendPropertiesFromStorageMap(storagePropertiesMap); +``` +where `storagePropertiesMap` is the catalog's **parsed** `StorageProperties` map (`getStoragePropertiesMap()`, vended-merged for REST). `getBackendPropertiesFromStorageMap` walks each `StorageProperties` and calls `getBackendConfigProperties()`, which yields the BE-canonical keys: `AbstractS3CompatibleProperties:106-120` emits `AWS_ENDPOINT/AWS_REGION/AWS_ACCESS_KEY/AWS_SECRET_KEY/AWS_TOKEN/…`; `HdfsProperties:163-200` emits the resolved `hadoop.`/`dfs.` config (user overrides **plus** legacy defaults like `ipc.client.fallback-to-simple-auth-allowed`). + +The cutover replaced this single normalized call with a raw prefix-copy loop. The connector **cannot** import fe-core's `StorageProperties` / `CredentialUtils` (SPI boundary, `tools/check-connector-imports.sh`), so it had no access to the normalization — hence the raw copy. + +## Design + +**A new `ConnectorContext` SPI hook `getBackendStorageProperties()`** that returns exactly legacy's `getBackendPropertiesFromStorageMap(storagePropertiesMap)`. The engine already holds the authoritative parsed map: `DefaultConnectorContext.storagePropertiesSupplier` (= `catalogProperty.getStoragePropertiesMap()`) was wired in fix #1 for `normalizeStorageUri`. The connector replaces its raw passthrough loop with one overlay of this map; the existing `vendStorageCredentials` overlay stays **after** it (vended wins on collision — legacy precedence). This mirrors the `vendStorageCredentials` / `normalizeStorageUri` seams exactly (the task-list's recommended pattern) and is the single source of truth — no re-ported normalization that could drift. + +**Why full replacement (D-048, user-signed), not object-store-only**: `getBackendPropertiesFromStorageMap` is the exact legacy `getLocationProperties()` value. For HDFS catalogs it is **strictly ≥** the current passthrough — `HdfsProperties.getBackendConfigProperties()` preserves every user `hadoop.`/`dfs.`/`fs.`/`juicefs.` override **and** adds the legacy-derived defaults the current loop drops (the review §211 MINOR, folded in for free). It also drops the `hive.*` keys the connector currently leaks — legacy never sends those to the scan location props, so dropping them **restores** parity. One SPI call replaces a fiddly prefix loop. + +### SPI (`fe-connector-spi/ConnectorContext.java`) — new default no-op method +```java +/** Returns the catalog's static storage credentials/config normalized to BE-canonical scan + * properties (AWS_* for object stores, hadoop/dfs for HDFS) — the engine runs the same + * CredentialUtils.getBackendPropertiesFromStorageMap legacy/iceberg/hive use.

The `storagePropertiesSupplier` field/ctor already exist (added in #1). **No ctor change.** Fail-behavior: `getBackendPropertiesFromStorageMap` on the parsed map does not throw (the map is already validated at catalog creation); an empty map yields an empty result (no overlay) — correct for credential-less warehouses, unlike `normalizeStorageUri` which must fail-loud on an un-normalizable *path*. + +### connector (`PaimonScanPlanProvider.getScanNodeProperties`) — replace the raw loop +Replace the `for (entry : properties) { if (prefix s3./oss./… /hive.) props.put("location."+key, val) }` loop (`:372-381`) with: +```java +// Static catalog-level storage credentials/config, normalized to BE-canonical keys (AWS_* for +// object stores, hadoop/dfs for HDFS).

No new connector imports (`Map`/`LinkedHashMap` already imported) → import-gate stays clean. + +## Implementation Plan +1. `ConnectorContext.java`: add `getBackendStorageProperties()` default returning `Collections.emptyMap()`. +2. `DefaultConnectorContext.java`: add the `getBackendStorageProperties()` override (one line; reuses the existing supplier + `CredentialUtils` import). +3. `PaimonScanPlanProvider.java`: replace the static prefix-copy loop with the `getBackendStorageProperties()` overlay (context-gated). +4. Tests (below). Build `:fe-core -am` (SPI + fe-core) then `:fe-connector-paimon -am`. +5. `tools/check-connector-imports.sh` must stay clean. + +## Risk Analysis +- **Regression on public/`s3://`/`hdfs://` warehouses**: for a correctly-configured catalog, `getStoragePropertiesMap()` holds the matching `StorageProperties`, so `getBackendPropertiesFromStorageMap` produces the same canonical keys legacy produces. Legacy ships exactly this map → parity. Public buckets get the same `AWS_*` (possibly empty creds + anonymous provider) as legacy. +- **HDFS catalogs**: full replacement is strictly ≥ the old passthrough (preserves user `hadoop.`/`dfs.`/`fs.`/`juicefs.` + adds legacy defaults). Behavioral delta is an *improvement* matching legacy. The only dropped keys are `hive.*`, which legacy never sent to scan location props. +- **Empty storage map** (local-FS warehouse, or non-plugin ctor): returns empty → no overlay. Legacy `getBackendPropertiesFromStorageMap({})` is also empty → parity. BE reads local files without creds. +- **No-context (offline unit tests only)**: the static overlay is skipped (gated, like the vended overlay) → no `location.*` storage props. Production always wires the context (`PaimonConnector:93`), so this only affects unit tests. The old offline behavior (emitting raw `location.s3.*`) was the *bug* — emitting nothing offline is correct. +- **Vended precedence**: vended overlay runs after the static overlay (unchanged), so vended still wins on collision. For REST catalogs the static map may lack keys; the per-table vended overlay supplies them — same two-step structure as today, only the static step is fixed. +- **`AWS_CREDENTIALS_PROVIDER_TYPE=ANONYMOUS` edge (investigated → non-issue)**: unlike legacy (which merges vended INTO the static `StorageProperties` then normalizes ONCE, so keys are present before the provider-type is computed), the connector normalizes static and vended in two steps. So a REST catalog that *also* carries a static object-store endpoint **without** static keys could have the static overlay emit `AWS_CREDENTIALS_PROVIDER_TYPE=ANONYMOUS` (blank-key branch of `AbstractS3CompatibleProperties:124-128`), which the vended overlay (carrying keys → no provider-type) would not clear. **Verified harmless against BE**: both `s3_util.cpp` credential providers (`_get_aws_credentials_provider_v1:383-389`, `_v2:448-455`) check explicit `ak`/`sk` **first** and return `SimpleAWSCredentialsProvider`, never reaching the `Anonymous` branch when keys are present. So the vended keys always win on BE; no regression. (For the primary B-9 case — static catalog WITH keys — the provider-type is null and never emitted.) +- **Other connectors**: identity (empty) SPI default; only paimon calls it. Zero impact on es/jdbc/maxcompute/trino. (hive/hudi connectors carry the same latent raw-passthrough pattern but are out of scope here.) + +## Test Plan + +### Unit Tests +1. **`DefaultConnectorContextBackendStoragePropsTest` (fe-core)** — build a real OSS `StorageProperties` map via `StorageProperties.createAll({oss.endpoint, oss.access_key, oss.secret_key})` (same machinery a real catalog uses), construct `DefaultConnectorContext` with it, assert `getBackendStorageProperties()` carries `AWS_ACCESS_KEY=ak` / `AWS_SECRET_KEY=sk` / a non-blank `AWS_ENDPOINT`, and carries **no** raw `oss.access_key` key. Assert the no-supplier ctor (`new DefaultConnectorContext("c",1L)`) returns empty. *Encodes WHY: BE only consumes canonical AWS_*; mutation = returning the raw oss.* keys or the no-op default → red.* +2. **`PaimonScanPlanProviderTest` (connector)** — three changes: + - **new** `getScanNodePropertiesNormalizesStaticCreds`: connector `properties` holds the raw `s3.access_key`; a context returns canonical `{AWS_ACCESS_KEY,AWS_SECRET_KEY,AWS_ENDPOINT}` from `getBackendStorageProperties()`. Assert `location.AWS_ACCESS_KEY` etc. present **and** `location.s3.access_key` **absent** (the raw alias is no longer leaked). *WHY: the B-9 bug is the raw alias reaching BE; mutation = re-introducing the raw passthrough → red.* + - **modify** `getScanNodePropertiesOverlaysVendedCreds`: static now comes from `getBackendStorageProperties()` (`{AWS_ACCESS_KEY=static-ak, AWS_ENDPOINT=static-ep}`); vended `{AWS_ACCESS_KEY=vended-ak, AWS_SECRET_KEY, AWS_TOKEN, AWS_ENDPOINT=vended-ep}`. Assert vended wins the `AWS_ACCESS_KEY`/`AWS_ENDPOINT` collision and adds `AWS_SECRET_KEY`/`AWS_TOKEN`. *WHY: vended overlays static (legacy precedence); mutation = overlaying static after vended → red.* + - **modify** `getScanNodePropertiesNoContextUnchanged` → `getScanNodePropertiesNoContextNoStorageProps`: 2-arg ctor (no context), raw `s3.endpoint` in props. Assert **no** `location.*` storage key is emitted (no NPE; the broken raw alias is never shipped). *WHY: the connector cannot normalize without the engine seam; mutation = NPE on null context, or re-adding the raw passthrough → red.* + +### E2E Tests (CI-gated — note, do not claim run) +- `test_paimon_*` native-read suites over a **private** S3/OSS bucket (static `s3.access_key`/`oss.access_key` catalog): `SELECT *` over raw parquet/orc must return rows (not 403). Requires live private-bucket creds → CI-gated. + +## SPI / logs +- New SPI method `ConnectorContext.getBackendStorageProperties` → register in `plan-doc/01-spi-extensions-rfc.md` (§22 / E14). +- User-signed scope decision (full legacy-parity replacement) → `plan-doc/decisions-log.md` D-048. +- No deviation: this is exact legacy parity (unlike #1's static-vs-vended scope note). + +## Result (2026-06-11 — implemented + verified) +- **Implemented exactly as designed**: SPI `ConnectorContext.getBackendStorageProperties` (empty default); `DefaultConnectorContext` override = `CredentialUtils.getBackendPropertiesFromStorageMap(storagePropertiesSupplier.get())` (reuses the #1-wired supplier + existing `CredentialUtils` import — **no ctor change**); `PaimonScanPlanProvider.getScanNodeProperties` replaces the raw prefix-copy loop with a context-gated overlay of that map (vended overlay stays after → vended wins). +- **ANONYMOUS-leak edge investigated → non-issue**: traced to BE `s3_util.cpp` — both credential providers (`_v1:383-389`, `_v2:448-455`) prefer explicit `ak`/`sk` over `cred_provider_type`, so a static-leaked `AWS_CREDENTIALS_PROVIDER_TYPE=ANONYMOUS` is never consulted when vended keys are present. No regression; no deviation logged. +- **Build + UT (green)**: `mvn test -pl :fe-core -am -Dtest=DefaultConnectorContext*` → `DefaultConnectorContextBackendStoragePropsTest` 2/0/0 (new), `DefaultConnectorContextNormalizeUriTest` 4/0/0 + `DefaultConnectorContextVendTest` 2/0/0 (unbroken). `mvn test -pl :fe-connector-paimon -am` → BUILD SUCCESS, module **217/0/0** (1 CI-gated skip); `PaimonScanPlanProviderTest` 18→19. Checkstyle clean (build-bound). `tools/check-connector-imports.sh` clean. +- **Fail-before/pass-after proven**: reverted the connector main change → `getScanNodePropertiesNormalizesStaticCreds` (AWS_ACCESS_KEY null) + `getScanNodePropertiesNoContextNoStorageProps` (raw alias shipped) go **red**; restored → green. (The 3rd test pins vended precedence, orthogonal — stays green either way.) +- **Tests added/changed**: fe-core `DefaultConnectorContextBackendStoragePropsTest` (OSS static creds → AWS_*, raw alias absent; no-supplier → empty); connector `PaimonScanPlanProviderTest` (+new `getScanNodePropertiesNormalizesStaticCreds`; modified `getScanNodePropertiesOverlaysVendedCreds` to canonical-key collision; renamed `getScanNodePropertiesNoContextUnchanged`→`getScanNodePropertiesNoContextNoStorageProps`). +- **Not run (CI-gated)**: live private-bucket (S3/OSS) native-read e2e — noted as gated, not executed. +- Logged: SPI RFC §22 (E14), decisions-log D-048 (full legacy-parity scope, user-signed).

Design C (user-signed D-049): BE's field-id matcher (table_schema_change_helper .cpp:312-430) reads only TField.id/name and a nested-vs-scalar type.type tag — no Doris Type, no tuple descriptor — and org.apache.doris.thrift.* is import-legal in connectors, so the connector builds the TSchema dictionary directly from paimon SchemaManager and ships it via the existing populateScanLevelParams hook (the seam DV-006 anticipated for hudi). Zero new SPI surface; connector-only. - current_schema_id = -1; history_schema_info = the -1/current (pinned) schema + one entry per SchemaManager.listAllIds() so every native file schema_id is covered (BE fails loud on a missing entry, never silent). - transport: base64 TBinaryProtocol carrier (a throwaway TFileScanRangeParams) via a props key, because getScanPlanProvider() is per-call (no shared state). Clean-room 3-lens review found 2 real BLOCKERs in the -1/current entry (both fixed + re-verified): (1) column-name casing — BE keys the table-side StructNode by the -1 entry's name verbatim while the native reader queries the lowercase Doris slot name, and current_schema_id=-1 never hits the ConstNode fast-path, so a mixed-case column crashed (std::out_of_range) even on never-evolved tables; fix lowercases ONLY top-level names (default-locale, matching the slot-name producer + legacy parseSchema:507; nested stays paimon-cased per legacy PaimonUtil:302). (2) time travel — the -1 entry used schemaManager.latest() (absolute latest) instead of the snapshot-pinned schema the tuple uses; fix builds it from FileStoreTable.schema() (pinned) and narrows the guard DataTable->FileStoreTable. Eager all-schemas read accepted as a fail-loud deviation (DV-027). Tests: PaimonScanPlanProviderTest +5 (field-id/name carriage, nested ARRAY/MAP/ STRUCT shape + struct-child ids, scalar tag, rename round-trip apply, top-level lowercase vs nested paimon-case, non-FileStoreTable skip). Module 222/0/0 (1 CI-gated skip), checkstyle clean, import-gate clean. e2e test_paimon_full_schema_change.groovy is CI-gated (not run). Design doc + D-049 + DV-026/DV-027 + SPI RFC §23 (no new SPI).

From 0579464983d9ac13fa5fb3cd1d5d9ca49d8eed4c Mon Sep 17 00:00:00 2001 From: morningman Date: Thu, 11 Jun 2026 20:10:13 +0800 Subject: [PATCH 020/128] =?UTF-8?q?fix:=20FIX-JDBC-DRIVER-URL=20=E2=80=94?= =?UTF-8?q?=20resolve+alias=20driver=5Furl=20for=20BE;=20validate=20at=20C?= =?UTF-8?q?REATE=20(B-8a=20+=20B-8b)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit rereview2 #4. JDBC-metastore-flavor paimon catalogs only. Connector-only, zero new SPI. Root cause: - B-8a (functional BLOCKER): PaimonScanPlanProvider.getBackendPaimonOptions forwarded driver_url to BE RAW and its `key.startsWith("jdbc.")` filter dropped the `paimon.jdbc.*` alias. A bare `jdbc.driver_url=mysql.jar` reached BE, where JdbcDriverUtils.registerDriver does `new URL(value)` -> MalformedURLException; a `paimon.jdbc.driver_url` alias was dropped outright. Legacy PaimonJdbcMetaStoreProperties.getBackendPaimonOptions emits `jdbc.driver_url=JdbcResource.getFullDriverUrl(driverUrl)` (resolved) + `jdbc.driver_class`. - B-8b (security): driver_url was loaded into the FE JVM (URLClassLoader) and shipped to BE with no format / jdbc_driver_url_white_list / jdbc_driver_secure_path validation, plus a stale "paimon is not in SPI_READY_TYPES" disclaimer (false since the B7 cutover added paimon to CatalogFactory SPI_READY_TYPES). Solution (reuses existing hooks; no new SPI surface): - B-8a: getBackendPaimonOptions now reads driver_url via firstNonBlank(JDBC_DRIVER_URL) (honors both the jdbc.* and paimon.jdbc.* alias) and emits the canonical `jdbc.driver_url` RESOLVED to a scheme-bearing URL plus `jdbc.driver_class` (BE accepts both alias forms). Resolution is extracted to a shared static PaimonCatalogFactory.resolveDriverUrl(driverUrl, env) so FE driver registration and the BE-bound options resolve a given driver_url identically. - B-8b: PaimonConnector overrides Connector.preCreateValidation to route a configured driver_url (either alias) through ConnectorValidationContext.validateAndResolveDriverPath at CREATE CATALOG (format/whitelist/secure-path; throws -> CREATE fails before the jar loads). Mirrors JdbcDorisConnector. Stale disclaimer replaced with an accurate note. Scope (user-signed D-050; see DV-028/DV-029): validation is CREATE-time only — parity with the JDBC reference connector. The FE-restart-reload / ALTER-CATALOG / scan-time re-validation gap is a pre-existing fe-core limitation shared by all plugin connectors (default config is permissive); accepted, with a cross-connector follow-up filed. BE-side paimon.jdbc.{user,password,uri} alias-drop is out of scope (BE deserializes the table from serialized_table; only driver_url/driver_class are consumed by registerDriverIfNeeded). Tests: PaimonScanPlanProviderTest +5 (resolve bare name, honor paimon.jdbc.* alias, both-aliases priority+override, preserve scheme-bearing, non-jdbc empty); new PaimonConnectorPreCreateValidationTest +5 (validate jdbc/alias, skip non-jdbc/no-driver_url, propagate rejection). Module 232/0/0 (1 CI-gated skip); fail-before verified (5/9 new tests red when neutered); checkstyle 0; connector import-gate clean. Live e2e (JDBC flavor + remote jar) is CI-gated.

For the common + case (`mysql.jar`, default dir) both yield `file://$DORIS_HOME/plugins/jdbc_drivers/mysql.jar`. A jar + present only in the legacy old dir resolves to the new dir and BE fails to find it. **Pre-existing** + simplification already used by the FE path; reused unchanged. → log in deviations-log. +2. **Fail-fast at CREATE (intended)** — `validateAndResolveDriverPath` requires a bare-name jar to exist + at CREATE CATALOG (was lazy at first scan). This is stricter but **correct** and matches the JDBC + connector. A CI-gated e2e creating a JDBC catalog without the jar present would now fail at CREATE + instead of first scan (it would have failed either way). +3. **No effect on non-JDBC flavors** — both Part A and Part C are gated on `metastore==jdbc` / `driverUrl` + present. filesystem/hms/rest/dlf unchanged. +4. **`context==null` (offline)** — Part A guards `context != null`; resolver falls back to + `doris_home="."`. Part C receives the `ConnectorValidationContext` as a method param (never null on the + real path; tests pass a fake). + +## Implementation Plan + +1. `PaimonCatalogFactory`: add `public static String resolveDriverUrl(String driverUrl, Map env)` + (body moved verbatim from `PaimonConnector.resolveFullDriverUrl`). +2. `PaimonConnector`: `resolveFullDriverUrl` delegates to the static; add `preCreateValidation` override + (Part C); replace stale comment (Part D). +3. `PaimonScanPlanProvider`: extend `getBackendPaimonOptions` (Part A); make it **package-private** for the + unit test. +4.

PluginDrivenExternalCatalog.createConnectorFromProperties hands the connector the raw catalog property map verbatim, so getOrDefault(underscore,"false") is always false. Even when the user enables the mapping at CREATE CATALOG, Paimon BINARY stays STRING and TIMESTAMP_WITH_LOCAL_TIME_ZONE stays DATETIMEV2 — a silent cutover regression (legacy PaimonExternalTable:350 reads the dotted key and honors it). The binary key is doubly drifted (separator . -> _ AND token varbinary -> binary_as_varbinary), so a generic dot->underscore normalizer would not fix it. Latent until the flag is enabled. Re-confirmation: M-crit was critic-surfaced (not 3-lens-gated), so the finding was independently re-verified by a 5-agent scout + adversarial synthesizer (REAL_BUG, high confidence; false-positive steelman rejected — dotted is canonical per the original feature PRs, every regression CREATE CATALOG, legacy parity, and the JDBC connector which kept dotted in the same SPI PR). Solution (connector-only, zero new SPI, no BE): re-point the two PaimonConnectorProperties constants to the canonical dotted keys (ENABLE_MAPPING_VARBINARY = "enable.mapping.varbinary", renamed from ENABLE_MAPPING_BINARY_AS_VARBINARY to match the CatalogProperty/JDBC/iceberg convention and fix both separator and token; ENABLE_MAPPING_TIMESTAMP_TZ = "enable.mapping.timestamp_tz") and update the one reference in PaimonConnectorMetadata. No logic change — the Options(mapBinaryToVarbinary, mapTimestampTz) arg order is already correct. BE-side consistency verified: PluginDrivenScanNode extends FileQueryScanNode and inherits the dotted-key read for the BE scan param (FileQueryScanNode:192-193,635-678), so FE column type and BE scan param now agree (they diverged before this fix). Scope: paimon-only (user-signed D-051). NEW hive + iceberg connectors share the identical root cause; logged as a cross-connector follow-up (DV-030), not fixed here. Rejected an fe-core dot->underscore normalizer (broader blast, breaks JDBC which already reads dotted, and insufficient for paimon's renamed token). Tests (PaimonConnectorMetadataTest): +2 UT. getTableSchemaHonorsDottedMappingKeys (bug-catcher) sets the dotted keys true and asserts BINARY->VARBINARY / LTZ->TIMESTAMPTZ; getTableSchemaDefaultsMappingFlagsOff (guard) asserts the default-off STRING/DATETIMEV2. Module 234/0/0 (1 CI-gated skip), checkstyle 0, import-gate clean. Fail-before verified: the bug-catcher reddens on the underscore key (expected but was ) while the guard stays green. E2E test_paimon_catalog_{varbinary,timestamp_tz}.groovy are CI-gated (enablePaimonTest=false + external fixture) — not run.

The underscore keys legitimately exist only in `FileFormatConstants` for the **TVF** path (`hdfs()`/`s3()` functions) — a different namespace, the likely copy-paste source. + +### Re-confirmation (M-crit was critic-surfaced, not 3-lens-gated) + +Independent 5-angle scout + adversarial synthesizer (workflow `wf_a3626c54-0db`) → **REAL_BUG, high confidence**, false-positive steelman rejected: +- Canonical key is dotted, proven by original feature PRs `c1eaede1260` (#57821), `a22da676bb0` (#59720); by every regression `CREATE CATALOG` (paimon/iceberg/hive/jdbc all use dotted — e.g. `test_paimon_catalog_timestamp_tz.groovy:26-32`, `.out:4` expects `timestamptz(3)`); by legacy parity (`PaimonExternalTable.java:350`); and by the JDBC connector (migrated in the **same** SPI PR) correctly keeping dotted (`JdbcConnectorProperties.java:66-67`). +- Failure manifests end-to-end (no normalization; single read site at ctor line 88). +- **Cross-connector**: NEW hive (`enable_mapping_binary_as_string` — a misnomer, not a semantic inversion) and iceberg (`enable_mapping_varbinary`) share the identical class of bug. **Out of scope here** ([DV-030]). + +### Why this is FE-only (no BE, no SPI) + +The **BE scan-param** side already reads the dotted key: `PluginDrivenScanNode extends FileQueryScanNode` and does **not** override `getEnableMappingVarbinary()/getEnableMappingTimestampTz()`, which read the dotted catalog getter and feed `params.setEnableMappingVarbinary/Tz` (`FileQueryScanNode.java:192-193,635-678`). Today the FE column-type side (connector) and the BE scan-param side **diverge** when the flag is set; re-pointing the connector's read to the dotted key makes both consistent again. No BE change; no new/changed SPI surface (the connector already receives the raw catalog map and already has the read site — only the key literals change). + +## Design + +Re-point the two connector constants to the **canonical dotted catalog keys**, fixing both the separator and (for binary) the renamed token, and align the binary constant name with the cross-connector convention (`CatalogProperty`/`Jdbc`/`Iceberg` all use `ENABLE_MAPPING_VARBINARY`). + +`PaimonConnectorProperties.java`: +- `ENABLE_MAPPING_BINARY_AS_VARBINARY = "enable_mapping_binary_as_varbinary"` → **`ENABLE_MAPPING_VARBINARY = "enable.mapping.varbinary"`** +- `ENABLE_MAPPING_TIMESTAMP_TZ = "enable_mapping_timestamp_tz"` → **`ENABLE_MAPPING_TIMESTAMP_TZ = "enable.mapping.timestamp_tz"`** + +`PaimonConnectorMetadata.buildTypeMappingOptions` (the single usage site): update the constant reference `ENABLE_MAPPING_BINARY_AS_VARBINARY` → `ENABLE_MAPPING_VARBINARY`. **No logic change** — the `Options(mapBinaryToVarbinary, mapTimestampTz)` arg order is already correct (binary first), and the read order is unchanged. + +### Why this approach (vs fe-core normalizer) + +Rejected: a dots→underscores normalizer in `PluginDrivenExternalCatalog.createConnectorFromProperties`. It is **broader-blast** (mutates the shared map all connectors + image/replay/SHOW CREATE see), would **break JDBC** (already reads dotted), and is **insufficient** (paimon's renamed token would still be missed). The constant re-point is the minimal, parity-correct fix and converges paimon with the JDBC/legacy dotted convention. + +## Implementation Plan + +1. `PaimonConnectorProperties.java:38-42` — rename + re-value the two constants (with clarifying Javadoc that these are the canonical dotted CREATE-CATALOG keys mirroring `CatalogProperty`). +2. `PaimonConnectorMetadata.java:~1020` — update the one constant reference. +3. Add fail-before/pass-after UTs (below). + +## Risk Analysis + +- **Blast radius**: two string literals + one reference, single connector. No SPI, no BE, no fe-core. +- **Behavior change is intended and parity-restoring**: only catalogs that **set** the flag change (latent until enabled — default `false` renders identically to before, so default-config catalogs are unaffected). +- **Misnamed-constant trap avoided**: do NOT invert any boolean (hive's `binary_as_string` is a misnomer, but that is out of scope here anyway). +- **No existing test pins the broken behavior** (verified) → no test churn beyond the net-new coverage. + +## Test Plan + +### Unit Tests (`PaimonConnectorMetadataTest.java`, offline harness) + +Build a `FakePaimonTable` whose `RowType` has a `BINARY` and a `TIMESTAMP_WITH_LOCAL_TIME_ZONE` column; drive `getTableHandle` → `getTableSchema` and assert the mapped `ConnectorType` names. + +1. **Bug-catcher** (`...HonorsDottedMappingKeys`): construct the metadata with `{"enable.mapping.varbinary":"true","enable.mapping.timestamp_tz":"true"}` → assert BINARY→`VARBINARY` and LTZ→`TIMESTAMPTZ`. + - *Fail-before* (underscore constants): both flags read `false` → `STRING` / `DATETIMEV2` → assertions red. *Pass-after*: green. +2. **Default guard** (`...DefaultsMappingFlagsOff`): construct with no mapping keys → assert BINARY→`STRING` and LTZ→`DATETIMEV2` (default-off preserved). Green both states — guards against accidentally flipping defaults. + +Each test documents WHY (the dotted catalog key is the user-facing contract fe-core sets/hides/defaults; reading the underscore key silently drops the flag) and the MUTATION that reddens it. + +### E2E Tests + +`test_paimon_catalog_varbinary.groovy` / `test_paimon_catalog_timestamp_tz.groovy` (the `.out` expects `timestamptz(3)`) already encode the dotted-key contract — but are **CI-gated** (`enablePaimonTest=false` in committed HEAD + external Paimon/HDFS fixture). Note as gated; do not claim to run them.

finding 没说的关键事实：① binary 键**双重漂移**（不只分隔符）② hive/iceberg **同根因**（决定 scope 要问用户）③ BE scan param 经 `FileQueryScanNode` 继承本就读点分（决定「无 BE」）。 +- **改 fe-core handle/scan 流前，先 grep 全 `metadata.getTableHandle` / scan-node 调用方**（历史教训：独立 handle 面绕 seam 会静默错行）。 +- **#6 两处 scope 决策先问用户**（D7 读-vs-DDL 不对称是否打破 / M-8「DLF」从句先核实）；P2 两条（#8/#9）严重度有争议 → **先找用户定 scope 再动手**。 +- **跨连接器 follow-up 累积**：[DV-028]（#4 CREATE-time-only 校验，全 plugin 连接器共有）+ [DV-030]（#5 hive+iceberg mapping-flag 键，同 paimon 根因）—— 若将来批量 close，二者都是「新连接器读法 vs fe-core 既有约定」的同类缝。 diff --git a/plan-doc/task-list-P5-rereview2-fixes.md

=?UTF-8?q?wire=20fs/jdbc=20HDFS=20authenticator=20(M-8)=20+=20wrap=20all?= =?UTF-8?q?=20read=20RPCs=20in=20doAs=20(M-11)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both are Kerberos-only (harmless on simple-auth: the no-op authenticator's execute() == task.call()). Root cause - M-8 (fe-core): paimon filesystem/jdbc catalogs over Kerberized HDFS lost UGI doAs on the cutover path. The HDFS HadoopExecutionAuthenticator is built only inside initializeCatalog(), which is dead on the plugin path (only legacy PaimonExternalCatalog calls it), so PluginDrivenExternalCatalog read the base no-op from getExecutionAuthenticator(). HMS was unaffected — it wires the authenticator in initNormalizeAndCheckProps(), which always runs. - M-11 (connector): metadata read RPCs (listDatabases/getDatabase/listTables/ getTable[handle+sys+resolveTable]/listPartitions) ran without executeAuthenticated; only the 4 DDL ops were wrapped (signed D7=B read-vs-DDL asymmetry). On a Kerberos HMS catalog these reads ran outside the catalog principal. Legacy wrapped every read. Fix - M-8 (filesystem+jdbc only; DLF/REST/HMS excluded — DLF uses Aliyun STS not Kerberos, the review's "DLF" clause was overstated): new internal fe-core hook MetastoreProperties.initExecutionAuthenticator(List) (default no-op), invoked by PluginDrivenExternalCatalog.initPreExecutionAuthenticator from the already-built storage list; filesystem/jdbc override it to build the HDFS authenticator (shared AbstractPaimonProperties helper), mirroring HMS. No connector change; no connector SPI change. - M-11 (full legacy parity, signed D-052, supersedes the D7=B read clause): wrap all 7 connector read RPCs in context.executeAuthenticated. A single resolveTable wrap covers all resolveTable callers (metadata + scan). Domain exceptions are caught INSIDE the lambda because Kerberos UGI.doAs wraps a thrown checked Catalog.*NotExistException in UndeclaredThrowableException. Tests - M-11: PaimonConnectorMetadataReadAuthTest (12) + 2 scan-path tests assert each read runs inside executeAuthenticated (RecordingConnectorContext failAuth/ authCount). Connector module 248/0/0 (1 CI-gated skip). - M-8: Paimon{FileSystem,Jdbc}MetaStorePropertiesTest assert getExecutionAuthenticator() returns HadoopExecutionAuthenticator after wiring without initializeCatalog; fe-core metastore-props 21/0/0 (DLF/HMS regression-clean). - fail-before verified red for both (M-8: stays base no-op AbstractPaimonProperties$1; M-11: authCount/log-empty). - True end-to-end doAs is live-Kerberos-e2e only (no paimon-kerberos suite); DV-031. Decisions D-052 (M-11) / D-053 (M-8); deviation DV-031; design plan-doc/tasks/designs/P5-fix-KERBEROS-DOAS-design.md.

Sites 1/6 keep their existing catch-all outside (absorbs wrapped exceptions). Risk: site 2 `databaseExists` gains an outer `catch(Exception)→DorisConnectorException` it didn't have — but it previously let such failures propagate as unchecked anyway (fail-loud preserved). +- **Perf**: one `executeAuthenticated` frame per metadata op (not per-split).

authenticator 行为一致、无回归）： + - **M-8（fe-core，filesystem+jdbc）**：翻闸后这两 flavor 在 Kerberized HDFS 上丢 UGI `doAs`——连接器 `PaimonConnector.createCatalog:194` 已把建 catalog 包进 `executeAuthenticated`，但其背后 authenticator 是**基类 no-op**：HDFS `HadoopExecutionAuthenticator` 仅在 `initializeCatalog()`(`PaimonFileSystemMetaStoreProperties:46`/`PaimonJdbcMetaStoreProperties:120`) 内建，而该方法在翻闸路径**死代码**（唯一 live 调用方=legacy `PaimonExternalCatalog:147`）→ `PluginDrivenExternalCatalog.initPreExecutionAuthenticator:130` 读到 `AbstractPaimonProperties:45` no-op。HMS 不受影响（`initNormalizeAndCheckProps:70` 即建，必跑）。**DLF/REST 排除**（DLF 用 Aliyun STS 非 Kerberos UGI、无 doAs 可丢；review「DLF」从句 **overstated**，已核）。 + - **M-11（连接器）**：metadata **读** RPC（listDatabases/getDatabase/listTables/getTable[getTableHandle+getSysTableHandle+resolveTable]/listPartitions）**不**包 `executeAuthenticated`，仅 4 DDL op 包（B3 **D7=B** 故意 read-vs-DDL 不对称）→ Kerberos HMS 上读跑在 catalog principal 之外。 +- **用户签字（本 session 两决策）**：**M-11 = full legacy parity 包全部 read RPC**（[D-052]，**取代 D7=B 的 read 从句**；legacy 本就包每个 read，仅包 listPartitions 是半吊子）；**M-8 = fix-now fe-core，filesystem+jdbc only**（[D-053]）。 +- **修**：M-8 = 新 fe-core hook `MetastoreProperties.initExecutionAuthenticator(List)`（default no-op）由 `PluginDrivenExternalCatalog.initPreExecutionAuthenticator` 用已安全建好的 `getOrderedStoragePropertiesList()` 调；filesystem/jdbc override 经 `AbstractPaimonProperties.initHdfsExecutionAuthenticator` 共享 helper 建 HDFS authenticator（镜像 HMS）——**零连接器改、非连接器 SPI**（`ConnectorContext`/`Connector` 表面未改，RFC 无须改）。M-11 = 7 处 read site 包 `context.executeAuthenticated`，`resolveTable`（metadata+scan 双 site）一处覆盖所有调用方（DRY）。**异常流关键**：Kerberos `UGI.doAs` 把 checked `Catalog.{Table,Database}NotExistException` 包成 `UndeclaredThrowableException`（仅 IOException/RuntimeException/Error 透传）→ domain 异常**必须在 lambda 内**捕获（镜像 legacy `getPaimonPartitions:104`）；scan `resolveTable` 对 `context==null`（2-arg ctor 离线测）走直连，同 `getScanNodeProperties` 既有约定。 +- **验证**：连接器模块 **248/0/0**（1 CI-gated skip）、fe-core metastore-props **21/0/0**（含 DLF/HMS regression-clean）、checkstyle 0、import-gate 净；**fail-before 双向红**（M-8 留 no-op `AbstractPaimonProperties$1`；M-11 3 测 authCount/log-empty 向红）。**真 doAs

`FIX-FORCE-JNI-SCANNER`（M-1，MAJOR，纯连接器，no SPI）**： +- **根因**：连接器只读 `paimonHandle.isForceJni()`（binlog/audit_log 的 NAME-forced 标志），**从不**读 session var `force_jni_scanner`；ORC/Parquet 永远走 native。JNI

session-properties map 读 `force_jni_scanner`（该 var 已在 map 里——连接器读 sibling `enable_paimon_cpp_reader` 即出自此），set 时把所有 data split 路由到 JNI。纯连接器、无 SPI、无 BE。真值闸=live e2e（CI-gated）。 +- ⚠️ **scope 无须问用户**（明确

router read only the name-derived handle flag paimonHandle.isForceJni() (the binlog/audit_log NAME hatch) and never consulted the session var force_jni_scanner, so ORC/Parquet always took the native reader — legacy's JNI escape hatch (SET force_jni_scanner=true, used to dodge native-reader bugs incl. the B2 schema-evolution class) was silently gone. The connector ported only two of legacy's three native-gate conjuncts (PaimonScanNode.java:430: !forceJniScanner && !forceJniForSystemTable && supportNativeReader); the dropped !forceJniScanner conjunct is M-1. Solution (pure connector; no SPI, no fe-core import, no BE param — legacy serializes nothing for this var): - new isForceJniScannerEnabled(session): byte-for-byte mirror of isCppReaderEnabled, reads key "force_jni_scanner" (byte-identical to SessionVariable.FORCE_JNI_SCANNER) from the same VariableMgr.toMap channel; null-guarded, default false (legacy default). - Site A (correctness): shouldUseNativeReader gains an explicit forceJniScanner param (mirrors legacy's sibling boolean 1:1) ANDed into the native gate; planScan passes isForceJniScannerEnabled(session). The handle name-force is OR-sibling, never replaced (binlog/audit_log intact). - Site B (correctness-neutral): getScanNodeProperties suppresses the native-only paimon.schema_evolution dict when force_jni_scanner routes every split to JNI (BE consumes it only on native ORC/Parquet ranges; JNI/cpp readers ignore it). Matches the connector's own documented contract. Tests (fail-before + pass-after both verified): - isForceJniScannerEnabledReadsSessionProperty: pins the exact key, default-false, null-safety. - forceJniScannerRoutesNativeEligibleSplitToJni: a native-eligible split must route to JNI when force_jni_scanner=true (legacy parity). - 3 existing shouldUseNativeReader calls updated for the new param. - Module 250/0/0 (+1 CI-gated live skip); connector import-gate + checkstyle clean. - Real BE reader selection is a CI-gated live-e2e check (no offline coverage).

The faithful shape is a sibling param, not a hidden OR. (The `cppReader = isCppReaderEnabled(session)` precedent one line above is a *serialization-format* flag, a different role — not the right analogy.) +- **Rule 9 (tests verify intent):** the routing decision is offline-undrivable (`FakePaimonTable.newReadBuilder()` throws), so the pure static is the **only** unit-testable seam for routing. A call-site OR would leave the new dimension testable only via the helper's *string-parsing* test, which **cannot fail when the routing logic changes** — exactly the anti-pattern Rule 9 forbids. The 3rd param makes `shouldUseNativeReader(false, /*forceJniScanner*/ true, native-eligible) == JNI` a mutation-tested fact. +- Cost: 3 existing test call sites add a `false` arg (mechanical; also makes them explicit). `forceJni` is **OR-sibling, never replaced** — replacing it would re-break binlog/audit_log routing. + +### 3.

BE consumes it **only** on the native ORC/Parquet path (`PaimonOrcReader`/`PaimonParquetReader::on_before_init_reader` → `TableSchemaChangeHelper::gen_table_info_node_by_field_id`, `be/.../paimon_reader.cpp:51-54,188-191`); the JNI reader (`paimon_jni_reader.cpp`) and cpp reader (`paimon_cpp_reader.cpp`) **never** reference it, and BE dispatch (`file_scanner.cpp:1045-1058`) only rewrites a range to native when `!paimon_split.__isset`. When `force_jni_scanner=true`, Site A routes **every** DataSplit to JNI (non-DataSplits were already JNI) → **zero** native ranges → the dict is dead weight. + +- KEEPING the emit is harmless (JNI ignores it; costs only the base64 serialize/transport). SKIPPING it is safe (nobody consumes it). +- **Why gate it anyway:** same root cause (var never consulted) + the connector's **own comment** (`:434-435`) already documents the dict as "Only meaningful when the table can take the native path (a DataTable read *without force_jni_scanner*); JNI splits never consult it." Leaving the gate blind to the session var contradicts that documented contract. The comment is updated to state the gate now honors `force_jni_scanner`. +- Both sites read the **identical** helper, so they cannot disagree (each SPI call gets a fresh provider — no shared instance state). + +### Out of scope (verified separate findings — do NOT touch) +- **M-2 count pushdown** — connector has no count branch (legacy runs it *before* the native gate, `:421`). Separate. +- **M-3 native sub-split sizing** — connector emits one range per RawFile vs legacy `fileSplitter.splitFile` (`:445-453`). Separate. +- **`IgnoreSplitType`** (`IGNORE_JNI`/`IGNORE_NATIVE`, legacy `:389/431/471`) — a different unimplemented session gate, **not** keyed on `force_jni_scanner`.

Harness property of both vars, not a connector defect; noted for the e2e author. +- **Site B null-session:** existing `getScanNodePropertiesSkipsSchemaEvolutionForNonFileStoreTable` passes `session=null`; null-guarded helper → `!isForceJniScannerEnabled(null) == true` → test stays green (verified, no NPE). +- **binlog/audit_log:** `forceJni` is OR-sibling, never replaced → name-force routing intact. + +## Test Plan + +### Unit Tests (offline FE, `PaimonScanPlanProviderTest`) +1. **`isForceJniScannerEnabledReadsSessionProperty`** (clone of `isCppReaderEnabledReadsSessionProperty`): assert `true` for `{"force_jni_scanner":"true"}`, `false` for `"false"`, `false` for empty map ("absent ⇒ default false"), `false` for null session. WHY: pins the exact key + default-false + null-safety that routing hinges on.

WHY: with `force_jni_scanner=true`, a native-eligible normal-table split must route to JNI (legacy parity `:430`). RED-MUTATION: drop `!forceJniScanner` → returns native → red. +3. **Updated existing 3** (`forceJniSysTable…`, `nonForcedSplitWithRawFiles…`, `nonForcedSplitWithoutNativeFiles…`): add `false` for the new param. The `(false,false,native)→native` and `(true,_,native)→JNI` cases stay pinned; regression guard that the widened signature didn't perturb routing. + +### Site B test coverage (honest limitation — Rule 12) +A dedicated red-before/green-after for the schema-evolution *emit suppression* is **not feasible offline**: `buildSchemaEvolutionParam` requires a real `FileStoreTable` with a `SchemaManager`, but the offline harness only has `FakePaimonTable` (returns empty dict regardless), matching the suite's deliberate offline-pure convention. So dropping the Site B gate would not turn any offline test red. Site B is therefore covered by: (a) the shared `isForceJniScannerEnabled` helper test (its only variable term), (b) code inspection + BE-source evidence of correctness-neutrality, (c) the gated live e2e. Stated explicitly rather than claimed. + +### E2E Tests (CI-gated, live paimon — not run here) +`SET force_jni_scanner=true; SELECT * FROM ` → reader=JNI (vs native when false). Real escape-hatch behavior is a **live-e2e-only** gate; no offline harness drives BE reader selection.

The JNI escape hatch (used to dodge native-reader bugs — incl. the B2 schema-evolution one) is gone. - **Connector**: `PaimonScanPlanProvider.java:261,439-441` (`shouldUseNativeReader`). **Legacy**: `source/PaimonScanNode.java:361,430` (`sessionVariable.isForceJniScanner()` gate). - **Fix sketch**: read `force_jni_scanner` from the session-properties map (the var is already in it — connector reads sibling `enable_paimon_cpp_reader` from there) and route all data splits to JNI when set. Pure connector. +- **✅ DONE** `05132a42668` (design [`P5-fix-FORCE-JNI-SCANNER-design.md`](./tasks/designs/P5-fix-FORCE-JNI-SCANNER-design.md)). Re-verified vs current code (4-scout + synthesizer workflow); finding confirmed, current sites = `PaimonScanPlanProvider.java:295` (router) + `:436` (schema-evo emit gate). **Site A** (correctness): new `isForceJniScannerEnabled(session)` (mirror of `isCppReaderEnabled`, key `force_jni_scanner`) → `shouldUseNativeReader` gains an explicit `forceJniScanner` param (mirrors legacy's 3-boolean gate `PaimonScanNode.java:430` 1:1; handle name-force is OR-sibling, never replaced). **Site B** (correctness-neutral): suppress the native-only `paimon.schema_evolution` dict when force-JNI (BE consumes it only on native ORC/Parquet ranges — verified `paimon_reader.cpp`/`file_scanner.cpp:1045-1058`). Pure connector, **zero SPI**, no fe-core import, no BE param (legacy serializes none). UT 250/0/0 (+1 CI skip), fail-before two-test-red verified, import-gate + checkstyle clean. Real BE reader selection = CI-gated live-e2e only. --- From 09f28cd7395b0f39e2cbe211faeb8c3f6ff4f979 Mon Sep 17 00:00:00 2001 From: morningman Date: Fri, 12 Jun 2026 10:06:51 +0800 Subject: [PATCH 028/128] =?UTF-8?q?fix:=20FIX-COUNT-PUSHDOWN=20=E2=80=94?= =?UTF-8?q?=20emit=20precomputed=20merged=20row=20count=20for=20COUNT(*)?= =?UTF-8?q?=20on=20plugin=20paimon=20(M-2)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: after cutover, COUNT(*) over a plugin-driven paimon table is result-correct but slow. The COUNT enum already reaches BE (FileScanNode.toThrift:90; PhysicalPlanTranslator:873 sets it on the plugin node, not excluded) and the per-range emit seam is already built (PaimonScanRange.Builder.rowCount -> paimon.row_count -> setTableLevelRowCount, byte-identical to legacy PaimonScanNode:303-308). The missing half is the signal + compute: DataSplit.mergedRowCount() is paimon-SDK-only (connector), and the getPushDownAggNoGroupingOp()==COUNT signal lives only on the fe-core node and reached nobody. So every split carried table_level_row_count=-1 and BE materialized the full post-merge row set just to count (file_scanner.cpp: 1298-1326) — costly on PK/MOR tables. Not pure-connector: the signal must cross the SPI boundary. Threading it via ConnectorSession (the FIX-FORCE-JNI precedent) was rejected — the agg-op is a per-query planner output, not a SET-variable, and would be a silent untyped channel. Solution (3 files; user signed off, D-054): - SPI (ConnectorScanPlanProvider): new default planScan overload carrying `boolean countPushdown`, delegating to the 6-arg variant — mirrors the limit/requiredPartitions extension chain; other connectors are no-op (E15). - fe-core (PluginDrivenScanNode.getSplits): read getPushDownAggNoGroupingOp()==TPushAggOp.COUNT and forward the flag. No post-loop math. - connector (PaimonScanPlanProvider): extract planScanInternal(...,countPushdown) (4-arg delegates false, new 7-arg delegates the flag); add the count short-circuit as the FIRST routing arm (a count-eligible split must not also emit a data range, else BE double-counts vs deletion vectors / PK merge); collapse-to-one — sum every count-eligible split's mergedRowCount and emit ONE JNI count range bearing the total (= legacy's <=10000 singletonList + assignCountToSplits case). New members: static isCountPushdownSplit + buildCountRange. Param shape = boolean (BE only needs COUNT-vs-not), scope = paimon-only (default no-op). legacy's >10000 parallel-split trim is intentionally dropped (connector has no numBackends, an fe-core-only concern) — perf-only divergence, result identical (DV-032). No new thrift, no BE change. Tests: connector PaimonScanPlanProviderTest +2 — isCountPushdownSplit eligibility on a real split (true/2, disabled/false); end-to-end planScan over a PARTITIONED PK table with asymmetric per-partition counts (2 + 3) asserting collapse-to-one carrying the SUM (5, unreachable from any single split) and no row_count when the flag is off. Connector 252/0/0 (1 CI-gated live skip), fe-core compile + checkstyle 0, import-gate clean. Fail-before verified: neuter isCountPushdownSplit->false -> the count tests red; mutate `countSum +=` -> `=` -> the cross-split-sum assertion red. Real BE CountReader selection / EXPLAIN = CI-gated live-e2e (existing legacy paimon count regression covers the BE contract). Adversarially reviewed (workflow wf_6ead7c2c-b58): one MAJOR caught and fixed (the collapse/sum test was degenerate on a single-split fixture); two MINORs refuted (batch-path signal moot for paimon; EXPLAIN count-line drop is cosmetic, noted in DV-032).

The connector's native arm emitted exactly one PaimonScanRange per RawFile (start=0, length=file.length()). Legacy PaimonScanNode:434-465 sub-splits each large file via determineTargetFileSplitSize + fileSplitter.splitFile. Result is correct (BE reads the whole file either way); only read parallelism regresses. Recon (wf_ad764bf6-1c9) confirmed: it is a real gap (ORC/Parquet are PLAIN/splittable, legacy does sub-split); DV x sub-split is SAFE (paimon deletion-vector rowids are GLOBAL file row positions, BE native readers report global positions even within a partial byte range, _kv_cache shares the DV bitmap across sub-splits keyed by path+offset, iceberg uses the identical machinery on routinely-split files); and it is pure-connector (the splitter math + 5 session vars re-stated with plain longs — the connector cannot import fe-core FileSplitter/SessionVariable). Solution (pure connector, zero SPI, zero fe-core; D-055): - Two pure statics: computeFileSplitOffsets(fileLength, targetSplitSize) ports FileSplitter.splitFile's specified-size branch byte-for-byte incl. the >1.1D tail guard (the last range absorbs a remainder up to 1.1x instead of a tiny tail split); determineTargetSplitSize(...) ports determineTargetFileSplitSize + applyMaxFileSplitNumLimit (the isBatchMode->0 branch omitted — paimon is never batch). - sessionLong + lazy resolveTargetSplitSize read the 5 file-split session vars via the VariableMgr.toMap channel (like isCppReaderEnabled) and sum native-eligible file sizes once per scan. - Native arm: emit one range per [start,length) sub-range via buildNativeRanges, attaching the SAME unmodified per-RawFile DeletionFile to EVERY sub-range (DV is global-row-position indexed; no offset re-basing). buildNativeRange gains (start, length); fileSize stays the whole file length. - Under COUNT(*) pushdown a native split that is not count-eligible (no precomputed merged count, e.g. a DV with null cardinality) is kept WHOLE (target size 0 -> one whole-file range), mirroring legacy splittable=!applyCountPushdown. The split-weight/target-size scheduling nicety is not ported (pre-existing native path already omitted it; perf/scheduling-only, not correctness) -> DV-033. Tests: connector PaimonScanPlanProviderTest +6 — computeFileSplitOffsets math (250MB/64MB->4 with 58MB tail, exact-multiple, small-file-whole, empty, target<=0); determineTargetSplitSize heuristic (file_split_size override, 32MB<->64MB threshold, max_file_split_num floor); end-to-end append-only fixture (tiny file_split_size -> >=2 contiguous sub-ranges tiling [0,fileLength); default -> 1 range); DV on every sub-range; whole-file under count pushdown. Updated the 3 existing buildNativeRange call sites to the new signature. Connector 258/0/0 (1 CI-gated live skip), checkstyle 0, import-gate clean. Fail-before verified: neuter computeFileSplitOffsets -> the 3 splitting tests red; attach DV only to the first sub-range -> the DV test red. Real BE multi-range + DV read = CI-gated live-e2e (legacy paimon regression covers the BE contract; no BE change). Adversarially reviewed (workflow wf_4ac7479d-39d): 2 confirmed and fixed (the count-pushdown sub-split parity gap + false comment; the missing DV-on-every-sub-range test), 2 refuted.

Most +count-eligible splits are siphoned to the count arm (`isCountPushdownSplit`), BUT a native-eligible +split whose merged count is **not** precomputed (e.g. a deletion vector with null cardinality) is NOT +siphoned and reaches the native arm with `countPushdown=true`. Legacy keeps such a split **whole** +(`splittable=false → one whole-file split`); the connector mirrors this by passing target size `0` +to `buildNativeRanges` under count pushdown (→ single whole-file range). Correctness-neutral either +way (BE sets per-scanner agg=NONE when a DV is present without a row count, so disjoint sub-ranges +count independently and the COUNT operator sums correctly), but matching legacy keeps the split count +byte-exact and avoids an undocumented divergence. The native arm is otherwise gated to ORC/Parquet +(`supportNativeReader`) = always PLAIN/splittable. + +## Out of scope / known gaps (honest) +- **Split-weight / target-size scheduling nicety:** legacy sets a per-split weight + targetSplitSize on + the `FileSplit` for `FederationBackendPolicy` balancing. The connector's native ranges omit + `selfSplitWeight` (**pre-existing** — the single-range native path already omitted it; #9 does not + regress it, it just emits more ranges). Scheduling-quality only, not correctness → [DV-033]. +- **Block-based splitting branch** (`FileSplitter:147+`) not ported — unreachable for the connector. + +## Risk analysis +- **Correctness:** unchanged. BE reads the same bytes whether 1 or N ranges; DV applies by global row + position per the recon. Contiguous tiling `[0..fileLength)` with no gap/overlap (unit-asserted). +- **#8 interaction:** count-eligible splits are siphoned to the count arm before the native gate. + Under count pushdown a native-eligible split that is NOT count-eligible (no precomputed merged + count) is kept WHOLE in the native arm (the count-pushdown splittable gate above) — legacy parity, + no sub-split, correctness-neutral. +- **Tiny files:** `fileLength <= 1.1 × target` → 1 whole-file range (unchanged behavior). + +## Test plan +- **Pure-static unit (fail-before drivable):** + - `computeFileSplitOffsets`: 250MB/64MB → `[0,64][64,64][128,64][192,58]` (1.1× tail keeps 58MB, no + 5th split); 256MB/64MB → 4 even; `fileLen ≤ 1.1×target` → 1 whole-file; `fileLength≤0` → empty; + `target≤0` → single. Assert contiguous tiling (no gap/overlap, Σlength = fileLength, last = remainder). + - `determineTargetSplitSize`: `file_split_size>0` returns it; total above/below + `max_file_split_size × max_initial_file_split_num` flips 64MB↔32MB; `max_file_split_num` floor + raises the size; defaults when keys absent. +- **End-to-end (offline via real local table + `sessionWithProps`):** set a tiny `file_split_size` so + even the sub-KB fixture file splits → assert `planScan` emits ≥2 native ranges that tile + `[0..fileLength)` contiguously. Do NOT pin the exact count (parquet byte size is encoder-dependent). +- **DV-on-every-sub-range (Rule 9, load-bearing):** `buildNativeRanges` with a `DeletionFile` + a + target that forces ≥2 ranges → assert EVERY sub-range carries the same (normalized) deletion file. + fail-before = attach the DV only to the first sub-range → red (a real DV-bearing split is live-e2e + only, so this is driven via the package-private `buildNativeRanges` with a hand-built `RawFile`+DV). +- **Count-pushdown whole-file:** `buildNativeRanges(..., targetSplitSize=0)` → exactly one whole-file + range (the count-pushdown splittable gate); mutation = sub-split under count pushdown → red. +- **fail-before:** neuter `computeFileSplitOffsets` to a single whole-file range → the multi-range + assertions go red; restore → green. +- **live-e2e (CI-gated):** real large-file parallelism + DV-bearing-file multi-range read — existing + legacy paimon regression covers the BE contract (no BE change). + +## Files +- `fe/fe-connector/fe-connector-paimon/.../PaimonScanPlanProvider.java` — 5 constants, 2 static helpers, + `sessionLong` + `resolveTargetSplitSize`, native-arm loop, `buildNativeRange(+start,+length)`. +- `fe/fe-connector/fe-connector-paimon/.../PaimonScanPlanProviderTest.java` — static-math tests + + end-to-end sub-split test; update 3 existing `buildNativeRange` call sites to the new signature. + +## Log entries +- `decisions-log.md`: D-055 (P2 scope sign-off = implement; pure-connector design). +- `deviations-log.md`: DV-033 (split-weight scheduling nicety not ported — pre-existing, perf-only). +- `01-spi-extensions-rfc.md`: none (zero SPI).

`paimonHandle.isForceJni()`（binlog/audit_log 名钉），**从不**读 session var `force_jni_scanner` → ORC/Parquet 永走 native；legacy 的 JNI 逃生舱（`SET force_jni_scanner=true`，用于绕 native-reader bug 含 B2 schema-evolution 那类）静默丢失。连接器只移植 legacy 三 conjunct 中的两个（`PaimonScanNode.java:430`：`!forceJniScanner && !forceJniForSystemTable && supportNativeReader`），丢的 `!forceJniScanner` 即 M-1。 -- **修**（纯连接器、**零 SPI**、无 fe-core import、无 BE param —— legacy 也不序列化此 var）： - - 新 `isForceJniScannerEnabled(session)`：逐字镜像 `isCppReaderEnabled`，读 key `force_jni_scanner`（byte-identical to `SessionVariable.FORCE_JNI_SCANNER`，同 `VariableMgr.toMap` 通道）；null-guard，默认 false（legacy 默认）。 - - **Site A**（correctness，`PaimonScanPlanProvider.java:295`）：`shouldUseNativeReader` 加显式 `forceJniScanner` 形参（1:1 镜像 legacy 三-boolean 闸），`planScan` 传 `isForceJniScannerEnabled(session)`。**handle 名钉是 OR-sibling，绝不替换**（binlog/audit_log 路由不变）。 - - **Site B**（correctness-NEUTRAL，`:436`）：force-JNI 时抑制 native-only `paimon.schema_evolution` 字典（BE 仅在 native ORC/Parquet range 消费它，JNI/cpp reader 全忽略——核 `paimon_reader.cpp:51-54,188-191` / `file_scanner.cpp:1045-1058`）；对齐连接器自身注释契约。 -- **关键设计定夺（本 session，内部工程判断，无须用户签字）**：`shouldUseNativeReader` 用**显式 3rd 形参**而非 call-site OR——**推翻 workflow synthesizer 的 call-site-OR 建议，采 legacy-parity scout**。理由：`force_jni_scanner` 是与既有 `forceJni`（=`forceJniForSystemTable`）语义并列的**路由**输入（legacy `:430` 即两 sibling boolean 同闸），call-site OR 会让新维度只能经 helper 的**字符串解析**测，而那测**routing 逻辑变了也不会红**（违 Rule 9）；3rd 形参让 `shouldUseNativeReader(false, true, native-eligible)==JNI` 成 mutation-tested 事实。`cppReader=isCppReaderEnabled(session)`（序列化格式 flag，非路由）不是正确类比。 -- **验证**：连接器模块 **250/0/0**（1 CI-gated live skip = `PaimonLiveConnectivityTest`）、import-gate 净、checkstyle 0；**fail-before 双向红**（neuter 丢 conjunct + helper return-false → 恰两新测红、其余 31 绿）。真 BE reader 选择 = **live-e2e only**（无离线 harness 驱动 BE reader 选择）。设计 [`P5-fix-FORCE-JNI-SCANNER-design.md`](./tasks/designs/P5-fix-FORCE-JNI-SCANNER-design.md)。 -- **Site B 测覆盖诚实声明**（Rule 12）：emit-suppression **无专属离线 red 测**——`buildSchemaEvolutionParam` 需真 `FileStoreTable`+`SchemaManager`，离线 harness 只有 `FakePaimonTable`（恒返空字典），故撤 Site B 闸不会红任何离线测。Site B 由：① 共享 `isForceJniScannerEnabled` helper 测（其唯一变量项）② BE-源 correctness-neutral 证据 ③ CI-gated live-e2e

From ea0da520a0e768ec5012c012f51b2be1ae882ed3 Mon Sep 17 00:00:00 2001 From: morningman Date: Fri, 12 Jun 2026 12:34:58 +0800 Subject: [PATCH 031/128] =?UTF-8?q?fix:=20FIX-CREATE-TABLE-LOCAL-CONFLICT?= =?UTF-8?q?=20=E2=80=94=20restore=20legacy=20local-conflict=20rejection=20?= =?UTF-8?q?in=20PluginDrivenExternalCatalog.createTable?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: the generic fe-core bridge PluginDrivenExternalCatalog.createTable collapsed legacy PaimonMetadataOps.performCreateTable's ordered remote-then-local existence probe into a single `exists` OR that was consumed ONLY by the IF NOT EXISTS branch. The !IF NOT EXISTS path ignored it and unconditionally called metadata.createTable. So a table present only in the local FE cache (a case-variant folded onto an existing name under lower_case_meta_names, absent on a case-sensitive remote) was CREATED remotely instead of rejected with ERR_TABLE_EXISTS_ERROR -- silent metadata corruption. Found by the P3 plugin-vs-legacy parity audit (adversarially verified); narrow, backend-dependent trigger (filesystem/jdbc paimon; HMS lowercases so both sides reject). Generic bridge -> also affects MaxCompute / future iceberg/hudi. Solution (fe-core bridge only; zero SPI/connector/BE): split the `exists` OR into remoteExists/localExists; under !IF NOT EXISTS, when localExists is true throw ERR_TABLE_EXISTS_ERROR (legacy local-arm parity). A remote-only conflict still falls through to connector.createTable (case A unchanged). Option-2 surgical (D-056); the residual case-A / all-DDL-op generic-error-code collapse is pre-existing and out of scope (DV-034). Tests: new PluginDrivenExternalCatalogDdlRoutingTest .testCreateTableLocalConflictWithoutIfNotExistsRejects (local-hit + remote-miss + !IF NOT EXISTS -> asserts DdlException thrown + metadata.createTable never called + no edit log). fail-before: exactly 1 new test red ("Expected DdlException...nothing was thrown"); pass-after: 26/0/0. fe-core checkstyle 0.

Update the now-stale inline comment at `:301-302`. + +Pure fe-core bridge change. **No SPI, no connector, no BE, no RFC.** No connector-import-rule concern (the +change is in fe-core). + +**2. `fe/fe-core/src/test/java/org/apache/doris/datasource/PluginDrivenExternalCatalogDdlRoutingTest.java`** +- Add one test `testCreateTableLocalConflictWithoutIfNotExistsRejects` (mirrors the existing local-arm test + `testCreateTableIfNotExistsExistingLocalTableReturnsTrue` but with `isIfNotExists=false`): remote + `getTableHandle` empty + local `getTableNullable` non-null + `!isIfNotExists` → asserts a `DdlException` + ("already exists") is thrown AND `metadata.createTable` is **never** called AND no edit log written. +- The static converter is mocked (as in `testCreateTableExistingTableWithoutIfNotExistsStillErrors`) so the + fail-before run cleanly distinguishes "fell through and created" from "rejected". + +# Risk Analysis + +- **Shared-code blast radius:** the change is in the generic bridge used by every plugin connector. It only + **adds** a rejection on a path that was previously a silent create; it cannot make a previously-succeeding + *correct* create fail (a local-only-conflict create was always wrong). Case A (remote-hit) is byte-for-byte + unchanged — the existing test `testCreateTableExistingTableWithoutIfNotExistsStillErrors` (remote-hit + + `!isIfNotExists`, no local stub → `localExists=false`) stays green. The two `IF NOT EXISTS` tests + (`...ExistingRemoteTableReturnsTrue...`, `...ExistingLocalTableReturnsTrue`) are unaffected (the + `isIfNotExists` branch is structurally identical). +- **`ErrorReport.reportDdlException` always throws**, so the subsequent fall-through to `metadata.createTable` + is reached only when `localExists` is false (remote-only conflict) — correct. +- **Parity scope:** restores case-B correctness to legacy. Residual: case-A error *code* stays generic + (pre-existing, out of scope, audit-classified cosmetic). +- **No editlog/replay impact:** the guard throws before any editlog write; rejected creates produce no log + entry on either side. + +# Test Plan + +## Unit Tests +- **New (fail-before / pass-after):** `PluginDrivenExternalCatalogDdlRoutingTest + .testCreateTableLocalConflictWithoutIfNotExistsRejects` — local-hit + remote-miss + `!IF NOT EXISTS` must + throw `DdlException` and never call `metadata.createTable`.

23d09436abe6c5b45910a43375240a468dad9949 Mon Sep 17 00:00:00 2001 From: morningman Date: Fri, 12 Jun 2026 13:26:17 +0800 Subject: [PATCH 033/128] =?UTF-8?q?fix:=20FIX-VARCHAR-BOUNDARY=20=E2=80=94?=

plugin read-direction type mapping PaimonTypeMapping.toVarcharType used `len >= 65533` to overflow a paimon VarCharType to STRING, while legacy PaimonUtil.paimonPrimitiveTypeToDorisType uses `len > 65533`. 65533 == ScalarType.MAX_VARCHAR_LENGTH is the legal exact-fit max VARCHAR, not the STRING wildcard, so the connector widened VARCHAR(65533) to STRING — a DESCRIBE / SHOW CREATE TABLE reported-type divergence (data and read correctness unaffected; STRING is a superset). Fix: change the boundary `>= 65533` -> `> 65533` to match legacy byte-for-byte (pure connector, 1 char). The unreachable `len <= 0` defensive guard is kept untouched (paimon VarCharType min length is 1). Tests: new read-direction PaimonTypeMappingReadTest pins the boundary intent (65532 -> VARCHAR(65532); 65533 -> VARCHAR(65533) [the fix]; 65534 -> STRING). Fail-before exactly the 65533 assertion red ("expected VARCHAR but was STRING"); pass-after green. Full module 260/0/0 (1 CI-gated live skip), checkstyle 0, connector import-gate clean. No BE/SPI change; reported-type parity otherwise covered by the CI-gated legacy paimon DESCRIBE regression.

From f135c75a3d50fe3bff34109bf3225e7bddb9306f Mon Sep 17 00:00:00 2001 From: morningman Date: Fri, 12 Jun 2026 13:39:45 +0800 Subject: [PATCH 034/128] =?UTF-8?q?fix:=20FIX-PARTITION-NULL-SENTINEL=20?= =?UTF-8?q?=E2=80=94=20scan-path=20coerces=20literal=20\N=20partition=20va?= =?UTF-8?q?lue=20to=20NULL=20(P4)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: PaimonScanRange.populateRangeParams routed paimon partition values through ConnectorPartitionValues.normalize, which applies Hive-directory null-sentinel coercion (a value of "\N" or "__HIVE_DEFAULT_PARTITION__" -> isNull). That coercion is correct for hudi (path-encoded partitions) but wrong for paimon: paimon partition values are TYPED — serializePartitionValue returns Java-null for a genuine null and the literal toString() otherwise — so a null is never a directory sentinel, and the coercion only ever bites a genuine literal value. A string partition column literally holding "\N" (which paimon does NOT reserve) or "__HIVE_DEFAULT_PARTITION__" was materialized as SQL NULL instead of the literal on the native ORC/Parquet read, diverging from legacy PaimonScanNode.setScanParams (source/PaimonScanNode.java:323-326) and yielding wrong rows for WHERE col='\N' / col IS NULL. The dominant genuine-NULL case is unaffected (both sides set isNull=true and BE ignores the rendered value string when is_null==true, partition_column_filler.h:40-44). Fix (1 file): derive isNull from the Java null ONLY (render genuine null as "", legacy-exact); drop the unused ConnectorPartitionValues import. ConnectorPartitionValues itself is left untouched — hudi (HudiScanRange.java:226) legitimately needs the Hive-directory coercion. The residual scan-vs-prune skew for a literal "__HIVE_DEFAULT_PARTITION__" value lives in the generic fe-core prune bridge (TablePartitionValues), is pre-existing and unchanged by this fix, and is logged as a deviation. Tests: new PaimonScanRangePartitionNullTest pins genuine-null -> (isNull=true, ""); literal "\N" -> (isNull=false, "\N"); literal "__HIVE_DEFAULT_PARTITION__" -> (isNull=false, verbatim); ordinary -> kept. Fail-before (re-inlined coercion) reds the literal + render rows; pass-after green. Full module 261/0/0 (1 CI-gated live skip), checkstyle 0, import-gate clean. Adversarial review (5 angles) SAFE_TO_COMMIT: total convergence of all 3 range builders on populateRangeParams; no query goes correct->wrong. No BE/SPI change; native partition materialization otherwise covered by the CI-gated legacy paimon partition regression.

Read-only adversarial recon `wf_6884d37b-8ef` re-verified all ~17 review §5/§7 items against current code; the sentinel ACCEPT verdict was refuted by a prune-path skeptic (converted to FIX) and M5.1's "cheap fallback" premise was refuted at impl level (confirmed ACCEPT).

=?UTF-8?q?=E2=80=94=20REST=20native=20object-store=20read=20throws=20on?= =?UTF-8?q?=20URI=20normalize=20(P9-1,=20BLOCKER)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: native ORC/Parquet reads on a Paimon REST catalog over object storage (oss/cos/obs/s3a) threw during FE planning — "StoragePropertiesException: No storage properties found for schema: oss". PaimonScanPlanProvider.normalizeUri routed both the data-file path and the deletion-vector path through ConnectorContext.normalizeStorageUri, which normalizes via the catalog's STATIC storage map. That map is empty by design for REST catalogs (vended creds are per-table/dynamic; CatalogProperty.initStorageProperties seeds an empty map when vended creds are enabled), so LocationPath.of(uri, {}) found no scheme entry and threw. shouldUseNativeReader has no flavor gate, so every REST native read hit it; the only escape was SET force_jni_scanner=true. DV-025 deferred this exact corner to FIX-STATIC-CREDS-BE / FIX-REST-VENDED, but those fixed credential down-flow to BE, not normalizeStorageUri — the deferral was never closed. Legacy parity: PaimonScanNode.doInitialize computes a vended-overlay storage map once (VendedCredentialsFactory.getStoragePropertiesMapWithVendedCredentials — vended REPLACES the empty static map for REST) and uses it for LocationPath.of at both the data-file (:443) and DV (:296) sites. Solution: route the per-table vended token into native URI normalization, replicating legacy precedence. - SPI: add default overload ConnectorContext.normalizeStorageUri(uri, token) that ignores the token and delegates to the 1-arg form, so every non-paimon connector is unaffected. - fe-core DefaultConnectorContext: extract the vended-typed-map build (filter cloud props -> StorageProperties.createAll -> index by Type) into a shared buildVendedStorageMap (single source of truth with vendStorageCredentials, no drift). The 2-arg override normalizes against the vended map when present and falls back to the static map otherwise (legacy "vended replaces static"); the 1-arg form delegates with a null token (byte-identical to prior behavior). vendStorageCredentials keeps an outer try so its fail-soft boundary is preserved across the refactor. - connector PaimonScanPlanProvider: extract the vended token ONCE per planScan (validToken() may refresh) and thread it through buildNativeRanges/ buildNativeRange to both normalize sites. Empty for non-REST (FileIO gate) and offline -> folds to the static path, so non-REST reads are byte-unchanged. Tests: - fe-core DefaultConnectorContextNormalizeUriTest (+3): vended-REST normalize under an empty static map (the gap that hid the bug twice); fail-loud when the token is also empty (proves the fix is the token, not a swallow); static-map path unaffected by an empty token. - connector PaimonScanPlanProviderTest (+1, 5 call sites updated): the per-table vended token is threaded verbatim to BOTH the data-file and DV normalize calls (RecordingConnectorContext now captures the 2-arg token). - The positive RESTTokenFileIO token-extraction path needs a live REST stack and remains E2E-gated (enablePaimonTest=false), not run here.

The real defaultFileFormat (= table.options().getOrDefault(file.format,"parquet"), computed in planScanInternal) was passed into buildJniScanRange and IGNORED, and was not passed into buildCountRange at all. PaimonScanRange .populateRangeParams then emitted fileDesc.file_format="jni". BE paimon_cpp_reader.cpp backfills paimon FILE_FORMAT/MANIFEST_FORMAT from this field (only when unset/empty, guarded !file_format.empty()) to avoid defaulting manifest.format=avro — with the invalid "jni" it injects MANIFEST_FORMAT=jni (and FILE_FORMAT=jni when unset) and the manifest read breaks. Key mechanism: the JNI formatType routing is gated by the paimon.split property (PaimonScanRange.populateRangeParams), NOT by the fileFormat string (that string drives formatType only on the native branch, where it is already real). So emitting the real orc/parquet leaves JNI routing intact and only corrects the inner fileDesc.file_format BE consumes — matching legacy PaimonScanNode.setPaimonParams, which sets setFormatType(FORMAT_JNI) AND setFileFormat(getFileFormat(...)) = the real data-file format. Solution (connector-only, no BE change): - buildJniScanRange: .fileFormat("jni") -> .fileFormat(defaultFileFormat) (the already-passed, previously-ignored parameter). Covers the non-DataSplit metadata-split call and the DataSplit JNI call. - buildCountRange: add a defaultFileFormat parameter, use it, and thread it from the call site in planScanInternal. - PaimonScanRange.Builder default: "jni" -> "" (every production caller sets the format explicitly; empty is the safe default — BE skips its format backfill on empty rather than ever injecting an invalid value). Tests: PaimonScanPlanProviderTest (+1) jniAndCountRangesCarryRealFileFormatNotJni — a real FileSystemCatalog PK table created with explicit file.format=orc (so the asserted value is the table option, distinct from the parquet fallback): force_jni_scanner=true scan -> every JNI data range carries "orc" (not "jni"); count-pushdown scan -> the collapsed count range carries "orc". Reverting either method to "jni", or dropping the threaded defaultFileFormat, turns the assertion red. Verified: connector 262/0/1skip (PaimonScanPlanProviderTest 43/0); checkstyle 0; import-gate clean. Design: plan-doc/FIX-JNI-FILE-FORMAT-design.md.

Every production caller sets `fileFormat` explicitly, so the default + is currently dead — but `"jni"` is the very invalid value this fix removes; an empty default is the + safe one (BE's `!file_format.empty()` guard then **skips** the backfill rather than ever injecting an + invalid format, and the native `formatType` branch only matches real `orc`/`parquet`). Pure safety net, + no behavioral change for any existing path. + +### Divergence note (accepted) +`defaultFileFormat` is the table's `file.format` option; legacy derives the JNI format path-suffix-first +(first data file), table-prop fallback. These differ only for a **mixed-format** table (e.g. after +`ALTER ... file.format` leaves old-format files), which paimon does not produce per-table; the table +option is the more correct per-table hint for the whole-split BE backfill. The native path keeps its +per-file suffix derivation (`buildNativeRange:450`, unchanged). + +## Implementation Plan +1. `buildJniScanRange`: `"jni"` → `defaultFileFormat`. +2. `buildCountRange`: add param + use it; update call site `:430`. +3. `PaimonScanRange.Builder.fileFormat` default `"jni"` → `""`. +4. Test (below); build connector + checkstyle + import-gate. + +## Risk Analysis +- **JNI routing**: unchanged — gated by `paimon.split` presence, not `fileFormat` (verified `:160`). +- **Native path**: untouched (already real per-file format). +- **BE**: no change; the fix makes the consumed value valid. Backfill only fires when the option is + unset/empty and now backfills a real format instead of `"jni"`. +- **Builder default `""`**: dead for all current callers; safer than `"jni"`/`"parquet"`. +- **System tables (binlog/audit_log)** go JNI; their `defaultFileFormat` = underlying table option (same + as legacy non-DataSplit fallback). Valid format emitted, not `"jni"`. + +## Test Plan +### Unit Tests +**connector — `PaimonScanPlanProviderTest`** (+1, real-table harness like the count tests): +- `jniAndCountRangesCarryRealFileFormatNotJni`: create a real PK table via `FileSystemCatalog`/`LocalFileIO` + with an explicit `.option("file.format", "orc")` (so `defaultFileFormat` is a deterministic `"orc"`, + distinct from the `"parquet"` fallback — proves the real table option is read, not a constant): + - `planScan(force_jni_scanner=true, countPushdown=false)` → every emitted range is a JNI data range + (`buildJniScanRange`); assert each `((PaimonScanRange) r).getFileFormat()` equals `"orc"` and not + `"jni"`. Also drives the call-site threading. + - `planScan(countPushdown=true)` → the collapsed count range (`paimon.row_count` present; + `buildCountRange`); assert `getFileFormat()` equals `"orc"`, not `"jni"` — pins the new `defaultFileFormat` + parameter + its threading from the call site. + - MUTATION: reverting either method to `.fileFormat("jni")`, or failing to thread `defaultFileFormat` + into `buildCountRange` → the `"orc"` assertion → red. + +### E2E Tests +None required (connector-only, no BE change). The BE backfill behavior is pre-existing; this fix only +changes the FE-emitted value from an invalid `"jni"` to the table's real format. + +## Files touched +-

From 3e382210415d2ff9bbc086387c4538ec4fc423f1 Mon Sep 17 00:00:00 2001 From: morningman Date: Fri, 12 Jun 2026 19:02:07 +0800 Subject: [PATCH 040/128] =?UTF-8?q?fix:=20FIX-INCR-SCAN-RESET=20=E2=80=94?= =?UTF-8?q?=20@incr=20drops=20legacy=20scan.snapshot-id/scan.mode=20reset?= =?UTF-8?q?=20(P2-1,=20MAJOR)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: PaimonIncrementalScanParams.validate stripped legacy's defensive null reset of scan.snapshot-id/scan.mode (PaimonScanNode:842-846), justified by a wrong "a fresh per-query Table can't inherit scan.*" rationale. A base table that PERSISTS scan.snapshot-id/scan.mode (legal & mutable via ALTER TABLE SET / TBLPROPERTIES / table-default.*) carries it on every fresh load. Without the reset, resolveScanTable's Table.copy merges the stale scan.snapshot-id with incremental-between and paimon 1.3.1 either THROWS ("[incremental-between] must be null when you set [scan.snapshot-id, scan.tag-name]") or silently downgrades the @incr read to FROM_SNAPSHOT at the stale id (wrong rows). The connector dropped exactly the safeguard legacy relied on. Solution (Option 2; design red-team wf_ffd11631-ed2, DESIGN-SOUND): keep validate() emitting only the non-null incremental-between* keys so the shared ConnectorMvccSnapshot SPI / handle stay null-free, and reapply the two null resets at the single Table.copy chokepoint via new PaimonIncrementalScanParams.applyResetsIfIncremental(scanOptions), called in PaimonScanPlanProvider.resolveScanTable. paimon copyInternal consumes a null value as options.remove(k), clearing the stale pin. The one edit covers BOTH callers (native/JNI scan planScanInternal + JNI serialized-table getScanNodeProperties). Gated on incremental-between / incremental-between-timestamp presence, so a genuine scan.snapshot-id / scan.tag-name pin passes through unchanged (no false positive). Strict legacy parity: resets scan.snapshot-id + scan.mode only. Corrected the now-refuted "byte-parity on a freshly-loaded base" rationale in the affected javadoc/comments. Tests: PaimonIncrementalScanParamsTest +4 (helper seeds the null resets for snapshot and timestamp windows; passes non-incremental pins through unchanged; no-op for empty/null) and reworded the keep-null-free validate() test; PaimonScanPlanProviderTest +1 real-table (FileSystemCatalog over a persisted scan.snapshot-id), proven fail-before (paimon throws) / pass-after; PaimonConnectorMetadataMvccTest WHY-comment reworded (assertions unchanged). Connector suites 20/44/37 green; checkstyle 0; import-gate clean. Connector-only — no SPI, no BE change. Live @incr-over-persisted-scan.snapshot-id E2E is CI-gated (enablePaimonTest =false), noted as gated.

That reconstruction was incomplete vs the legacy *Properties classes, so paimon catalogs on several storage backends failed FE-side catalog/metadata access (the live FileSystemCatalog/HiveCatalog/JdbcCatalog could not resolve the storage FileIO). Solution (connector-only; no fe-core/SPI/BE change): - Extract a shared applyS3aBaseConfig helper (port of AbstractS3CompatibleProperties.appendS3HdfsProperties) taking caller-resolved creds AND the 4 tuning values, so each scheme passes its OWN aliases/defaults. - 4a OSS: derive fs.oss.endpoint from region when blank (oss-[-internal].aliyuncs.com, default -internal, publicAccess from dlf.access.public/dlf.catalog.accessPublic), MOVED from the DLF-local block into the shared OSS block (so filesystem+hms flavors get it too); also emit the S3A base for OSS. Removed the now-dead DLF-local derivation block. - 4b S3: emit fs.s3a.path.style.access + connection.maximum/request.timeout/timeout. Tuning defaults are per-backend: S3=50/3000/1000 (incl AWS_* alias twins), OSS/COS/OBS=100/10000/10000 (a single shared default would silently mis-tune AWS S3). - 4c COS/OBS: new applyCanonicalCosConfig/ObsConfig. Detection mirrors legacy guessIsMe (endpoint/warehouse PATTERN: myqcloud.com / myhuaweicloud.com) OR a cos./obs.-prefixed key, NOT scheme-key-only (a cosn:// catalog configured with only s3.endpoint=cos...myqcloud.com would be missed otherwise). Each emits the S3A base (cosn/obs FS impl is S3AFileSystem, which reads fs.s3a.*) THEN the unconditional fs.cosn.* / fs.obs.* keys; OBS prefers the native OBSFileSystem when classpath-available. - S3 endpoint-from-region (user-approved, same defect class as the OSS P8-1 fix): region-only AWS S3 derives https://s3..amazonaws.com. - 4d HMS username: resolve hadoop.username from firstNonBlank(hive.metastore.username, hadoop.username) (alias priority), run AFTER the storage overlay so the raw hadoop.* passthrough cannot clobber it. - 4e (folded in, pre-existing MAJOR found in impl review): the kerberos block forced hadoop.security.authentication=kerberos before applyStorageConfig, so a kerberized-HMS + simple-HDFS catalog had it clobbered back to simple by the raw hadoop.* passthrough (auth=simple but sasl=true -> broken GSSAPI). Relocated the kerberos block to run AFTER the overlay, mirroring legacy initHadoopAuthenticator-last ordering. Design red-team (wf_a6385c61-669, 5 skeptics + completeness critic) caught the divergent tuning defaults, the endpoint-pattern detection gap, and the unconditional fs.cosn.*/fs.obs.* requirement before coding; impl verification (wf_f90260cb-5e6) confirmed byte-for-byte legacy key/alias/default fidelity and found 4e. Tests: PaimonCatalogFactoryTest +15 (S3 endpoint-from-region, S3 50/3000/1000 tuning, path-style, OSS endpoint-from-region filesystem+hms, OSS S3A base, COS keys + pattern-detect + unconditional region, OBS keys + pattern-detect, no-COS/OBS-for-plain-S3, HMS username alias + priority, kerberos-survives-simple-HDFS). The priority + kerberos tests are RED on the pre-move ordering. Verified: connector 56/0/0 + full module green; checkstyle 0; import-gate clean.

So FileSystem/SecurityUtil loaded child-first while S3AFileSystem resolved from the parent 'app' loader -> cross-loader ClassCastException ('S3AFileSystem cannot be cast to FileSystem') and a permanent SecurityUtil. poison ('Could not initialize class ...SecurityUtil', 'DNSDomainNameResolver not DomainNameResolver', 'ServiceConfigurationError: NullScanFileSystem not a subtype'), cascading to 'Unknown database X'. ~39 of 42 external-regression suites failed on the af2037 TeamCity run; not fixed by any later commit. Solution (self-contained plugin — aligns with fe-core dropping hadoop/hive-catalog-shade after full connector migration; does NOT lean on the parent): - pom: add hadoop-aws (the only missing FS impl, S3AFileSystem; DistributedFileSystem already comes from the transitive hadoop-client-api). hive-common stays bundled. - PaimonCatalogFactory.buildHadoopConfiguration: conf.setClassLoader(plugin loader) so Configuration.getClass("fs..impl") resolves the FS impl from the plugin loader. - PaimonConnector.createCatalogFromContext (single chokepoint for all flavors): pin the thread-context classloader to the plugin loader around catalog creation so the FileSystem ServiceLoader and SecurityUtil static init resolve from the child. Mirrors JdbcConnectorClient / ThriftHmsClient. Tests: connector build SUCCESS + all connector UTs 0 fail/0 error; plugin lib/ now contains hadoop-aws/S3AFileSystem; checkstyle + connector import-gate clean. The full runtime proof is the docker external paimon suite (CI-gated, enablePaimonTest) — not run locally. See plan-doc/FIX-PAIMON-HADOOP-CLASSLOADER-{design,summary}.md.

The paimon plugin runs child-first, so JindoOssFileSystem resolves from the parent and cannot be cast to the plugin's child-loaded org.apache.hadoop.fs.FileSystem -> "JindoOssFileSystem cannot be cast to FileSystem" -> "Unknown database" on first OSS listing (paimon_base_filesystem, test_paimon_deletion_vector_oss). The maven route is unbuildable (jindo-sdk/jindo-core are bound to an undeclared jindodata repo -> "present but unavailable"; runtime jindofs is 6.10.4, not in maven). Solution: after deploying the connector plugins, copy the jindofs jars (already placed in fe/lib/jindofs by post-build.sh) into the paimon plugin lib so JindoOssFileSystem loads child-first alongside the plugin's own hadoop FileSystem. Naturally gated (no-op unless --jindofs/DISABLE_BUILD_JINDOFS=OFF).

Solution: bundle the AWS SDK v2 (software.amazon.awssdk:s3 + apache-client, BOM-managed 2.29.52) into the plugin child-first, so the plugin's S3A registers against its OWN ExecutionAttribute static. s3's compile closure brings sdk-core (ExecutionAttribute); apache-client is explicit (hadoop-aws wires ApacheHttpClient). software.amazon.awssdk stays child-first (not parent-first) — the separate child SDK copy is the point.

The per-split PaimonScanRange.populateRangeParams emits the partition columns as columnsFromPath (so the BE APPENDS them), but the connector never emitted the scan-node-level path_partition_keys property, so PluginDrivenScanNode.getPathPartitionKeys() returned empty -> FileQueryScanNode.initSchemaParams did NOT exclude the partition columns from the file/decode set (num_of_columns_from_file + classifyColumn). Since paimon physically stores partition columns IN the ORC data file, the native OrcReader both DECODED dt/hh from the file AND APPENDED them from columnsFromPath -> a row-count double-fill (dt column rows=2 vs data block rows=1) that aborts the BE via DCHECK(block->rows()==col.column->size()) at vorc_reader.cpp:2638 (native ORC, intermittent under the random force_jni_scanner fuzz). Legacy PaimonScanNode.getPathPartitionKeys() returned [dt,hh] and drove BOTH the file-column exclusion AND the append from one source, so it never double-filled. Solution: emit the path_partition_keys scan-node property (lower-cased partition key names, matching the columnsFromPath keys and the Doris column names) in PaimonScanPlanProvider.getScanNodeProperties when the table is partitioned. This restores the legacy invariant — the BE excludes partition columns from the file decode set and appends them exactly once — for both the native ORC path (excluded from decode + appended from columnsFromPath) and the JNI path (projected out of required_fields + filled by _fill_columns_from_path). Mirrors the hive connector. The BE is unchanged. Tests: PaimonScanPlanProviderTest.getScanNodePropertiesEmitsPathPartitionKeysForPartitionedTable pins that a partitioned paimon table emits path_partition_keys.

Runtime gate: docker enablePaimonTest=true.

Maven-shade rewrites bytecode + references and signatures together, so the relocation is internally consistent. **Low risk**, + backed by the working hive-catalog-shade precedent that ships the identical paimon 1.3.1 + + metastore + relocated-thrift combination. + +3. **DLF `ProxyMetaStoreClient` path** (`PaimonCatalogFactory:428` sets + `metastore.client.class = com.aliyun.datalake.metastore.hive2.ProxyMetaStoreClient`). The DLF + client is **not** in this shade module (it lives in `metastore-client-hive3` / DLF SDK, not + bundled in the paimon plugin today either). DLF was already a cutover-gated unknown (pom NOTE + lines 175-182). This fix does not regress DLF, but **does not add DLF either** — DLF remains + gated by live-e2e and is out of scope for the HMS `NoClassDefFound` fix. Flag for the DLF + ticket: when DLF is wired, its `ProxyMetaStoreClient` references original-package + `org.apache.thrift.*`; it would need to be relocated together (added to this shade module's + artifactSet) to stay consistent. + +4. **Fastutil collision** — neutralized by the defensive `it.unimi.dsi.fastutil` relocation in + this module (the reason we build a paimon-scoped shade instead of reusing + hive-catalog-shade-3.1.1 which ships un-relocated fastutil). + +5. **Two paimon-hive copies?** The shade jar contains `org.apache.paimon.hive.*` (not relocated). + The connector plugin must NOT also carry a raw `paimon-hive-connector-3.1.jar` (we remove that + dep in step 3). Verify post-build that `paimon-hive-connector-3.1-*.jar` is **gone** from + `lib/` and only the shade jar provides `org.apache.paimon.hive.*` — otherwise a child-first + duplicate-class hazard. (paimon-**core** stays as its own jar; the shade excludes it.) + +6. **HiveConf class identity across the plugin.** The shade bundles hive-common 2.3.9 `HiveConf`; + the connector's `buildHmsHiveConf` constructs `new HiveConf()` resolved child-first from the + shade. Because both the `HiveConf` instance and the `getProxy(HiveConf,...)` signature come + from the same (shaded) hive-2.3.9, identity matches. **Low risk**; verify no second + `org.apache.hadoop.hive.conf.HiveConf` remains in `lib/` after removing the raw hive-common + dep. + +--- + +# Test Plan + +## Unit Tests + +- The existing `fe-connector-paimon` UTs (`PaimonCatalogFactoryTest`, the offline + `PaimonTableSerdeRoundTripTest`, the 46-test suite referenced in CI 968880) must still pass + unchanged. They exercise `buildHmsHiveConf`/`buildDlfHiveConf` (HiveConf assembly), flavor + resolution, and the FE→BE serde round-trip — the last one transitively exercises the + **doris-gen TSerializer (0.16.0) path** that RC-1 protects, so a green round-trip test is the + unit-level guard that the shade change did not re-split `TBase`. No new UT is needed: the + failure is a packaging/classloader fault that **cannot reproduce in a single-classloader UT** + (the whole point of the RC-5/RC-1 lineage — these bugs only surface under the docker + plugin-zip child-first loader). +- Run: `mvn -pl fe/fe-connector/fe-connector-paimon -am test` (the `-am` is required, per the + repo's `${revision}` gotcha, to also build the new shade module). + +## E2E Tests + +**Static jar verification (proves the class is now reachable, before docker):** +1. `mvn -pl fe/fe-connector/fe-connector-paimon-hive-shade,fe/fe-connector/fe-connector-paimon + -am package` +2.

The 5 tests are PURE DISPLAY gaps — data queries return correct values; only the explain text was missing the lines (plugindriven-explain-override-gap re-manifested for paimon). - solution (paimon-gated so other plugin connectors stay byte-unchanged): * SPI: ConnectorScanRange.getPushDownRowCount() (-1 default) + isNativeReadRange() (false default); ConnectorScanPlanProvider.getDeleteFiles(TTableFormatFileDesc) (empty default). * PaimonScanRange overrides the two getters (paimon.row_count / paimon.split). * PaimonScanPlanProvider.appendExplainInfo emits paimonNativeReadSplits from synthetic count keys the node injects; getDeleteFiles ports legacy PaimonScanNode.getDeleteFiles. * FileScanNode: behavior-neutral extract-method appendBackendScanRangeDetail (verbatim VERBOSE block). * PluginDrivenScanNode: accumulate native/total + pushdown-count in getSplits (pure statics); override getDeleteFiles; emit 'pushdown agg' UNGATED (restores the line FileScanNode emits for every other scan node), VERBOSE delete block paimon-gated, paimonNativeReadSplits paimon-only. - fixes Class E: test_paimon_count, test_paimon_deletion_vector, test_paimon_deletion_vector_oss, test_paimon_catalog_varbinary, test_paimon_catalog_timestamp_tz. - tests (independently re-run, build cache disabled): PluginDrivenScanNodeExplainStatsTest 7/7, PluginDrivenScanNodeDeleteFilesTest 4/4, PaimonScanExplainTest 9/9; existing PluginDrivenScanNodePartitionCountTest 5/5 (no shared-node regression). Tests encode WHY (the -1 sentinel survival, 0/N native accounting). Runtime gate: docker enablePaimonTest=true comparison-mode run cross-checks the values vs .out. - shared FileScanNode/PluginDrivenScanNode changes verified non-perturbing to es/jdbc/maxcompute/ iceberg/hive (extract is byte-identical; pushdown agg matches FileScanNode's unconditional emit).

Instead, **selectively re-emit** the two +FileScanNode line families that are paimon-asserted, keeping the existing custom header: + +- **`pushdown agg=COUNT (n)`**: after the connector `appendExplainInfo` call, emit + ``` + output.append(prefix).append("pushdown agg=").append(getPushDownAggNoGroupingOp()); + if (getPushDownAggNoGroupingOp() == TPushAggOp.COUNT) { + output.append(" (").append(getTableLevelRowCountForExplain()).append(")"); + } + output.append("\n"); + ``` + This line is connector-agnostic and safe to emit for ALL plugin connectors (it mirrors what + FileScanNode prints for every other scan node — its absence on plugin nodes is itself an inconsistency). + **No gating needed** for the `pushdown agg` line; it is universally correct. + - Requires the count value to reach the node. See Change C. + +- **`dataFileNum/deleteFileNum/deleteSplitNum`** (VERBOSE block): this is the expensive per-BE loop in + `FileScanNode:151-213`. Rather than duplicate ~60 lines, factor the VERBOSE per-BE block out of + `FileScanNode.getNodeExplainString` into a `protected` helper + `appendBackendScanRangeDetail(StringBuilder, prefix)` and call it from `PluginDrivenScanNode` under the + same `detailLevel == VERBOSE && !isBatchMode()` gate. (Surgical alternative if extraction is undesirable: + copy the block; but extraction avoids drift and is preferred by Rule 3's "don't fork" reading.) The block + calls `getDeleteFiles(rangeDesc)` — see Change B for the plugin override. + +### Change B — `getDeleteFiles` override on the plugin node, via a generic seam + +`PaimonScanRange.populateRangeParams` already sets `TPaimonFileDesc.setDeletionFile(...)` on the thrift +range from the `paimon.deletion_file.path` property. The deletion-file path is therefore present in the +serialized `TFileRangeDesc` at explain time. Override `getDeleteFiles(TFileRangeDesc rangeDesc)` on +`PluginDrivenScanNode` to read it. + +Two options for keeping it generic (the node is shared): +- **Option B1 (preferred):** add a default SPI hook + `ConnectorScanPlanProvider.getDeleteFiles(TFileRangeDesc) -> List` returning `emptyList()` by + default; `PaimonScanPlanProvider` overrides it to read `TTableFormatFileDesc.getPaimonParams() + .getDeletionFile().getPath()` (a verbatim port of legacy `PaimonScanNode.getDeleteFiles:337-357`). The + node's override delegates to `connector.getScanPlanProvider().getDeleteFiles(rangeDesc)`. This keeps the + thrift-shape knowledge in the paimon connector and leaves es/jdbc/mc returning empty (no `deleteFileNum` + change — though their VERBOSE block still won't print unless they also opt in, see gating below). +- **Option B2 (rejected):** read `TPaimonFileDesc` directly in fe-core's `PluginDrivenScanNode`. Rejected: + bakes paimon thrift knowledge into the shared node, and the legacy fe-core PaimonScanNode already imports + `TPaimonDeletionFileDesc`/`TPaimonFileDesc` so the precedent exists, but B1 is cleaner for the SPI. + +### Change C — thread the count-pushdown sum back to the node + +`PaimonScanPlanProvider` already encodes the summed count on the single collapsed count range as the +`paimon.row_count` property (`PaimonScanRange` builder `.rowCount(...)` → `props["paimon.row_count"]`, +consumed BE-side by `populateRangeParams:202-205`). In `PluginDrivenScanNode.getSplits`, after building the +`PluginDrivenSplit`s, scan the ranges and, if `countPushdown` is active, read `paimon.row_count` from the +range properties and call `setPushDownCount(sum)`. Generic implementation (no paimon import): +``` +if (countPushdown) { + for (ConnectorScanRange r : ranges) { + String rc = r.getProperties().get("paimon.row_count"); // generic key lookup + if (rc != null) { setPushDownCount(Long.parseLong(rc)); break; } + } +} +``` +For deletion_vector tables no count range is emitted → no `paimon.row_count` → `tableLevelRowCount` stays +`-1` → `pushdown agg=COUNT (-1)`. Correct. + +The property key `paimon.row_count` is paimon-specific but harmless to look up generically (absent for +other connectors). To avoid hard-coding a paimon key in the shared node, optionally promote it to a generic +`ConnectorScanRange` getter `getPushDownRowCount() -> long (default -1)` that `PaimonScanRange` overrides +from its `rowCount` field; the node reads `r.getPushDownRowCount()`. **Preferred:** the generic getter, to +keep the shared node connector-agnostic (consistent with Rule 11). + +### Change D — accumulate native/jni split counts and emit `paimonNativeReadSplits` + +`paimonNativeReadSplits` is intrinsically paimon-specific. Emit it from the connector via a NEW +`appendExplainInfo` override on `PaimonScanPlanProvider` — BUT `appendExplainInfo` only receives the +`nodeProperties` map, NOT the per-scan split counts (those are computed in `planScan`, after +`getScanNodeProperties`). So the counts must be threaded through the node. + +Chosen approach: classify ranges in `PluginDrivenScanNode.getSplits` (where ranges are already iterated) +and stash counts, then emit via the connector's `appendExplainInfo` by passing them through a small +augmented props map, OR — simpler and matching legacy — have the connector own the string but feed it the +counts. Concretely: + +- A native range = `ConnectorScanRange` whose `getRangeType()` is `FILE_SCAN` with a `getPath()` present + and NO `paimon.split` property (paimon native sub-splits set `path`/`fileFormat`, no `paimon.split`). +- A jni/count range = has the `paimon.split` property. + +Cleanest generic seam: add `ConnectorScanRange.isNativeReadRange() -> boolean (default false)` that +`PaimonScanRange` overrides (`true` when `paimon.split == null && path != null`). In +`PluginDrivenScanNode.getSplits`, after building splits, compute +`nativeCount = count(isNativeReadRange)` and `totalCount = ranges.size()`, store in two node fields +(`int rawFileSplitNum`, `int totalSplitNum` — generic names; or a single `scanRangeReadStats` map). Then in +`getNodeExplainString`, pass these to the connector via `appendExplainInfo`. Since `appendExplainInfo`'s +signature is `(StringBuilder, String prefix, Map nodeProperties)`, thread the counts by +**adding them into a copy of the props map** the node passes to `appendExplainInfo` (e.g. +`__native_read_splits` / `__total_read_splits` synthetic keys), and have `PaimonScanPlanProvider +.appendExplainInfo` read them and emit `paimonNativeReadSplits=raw/total`. This keeps the paimon string in +the paimon connector and needs no SPI signature change. + +**Gating:** `appendExplainInfo` is already connector-dispatched (only the active connector's provider runs), +so `paimonNativeReadSplits` is emitted ONLY for paimon. es/jdbc/mc providers do not emit it.

The plugin runs child-first and no longer carries an hdfs FileSystem impl: hadoop-common's service file registers only Local/viewfs/Har/Http(s), and FIX-PAIMON-HMS-THRIFT-SHADE (5ac8c302596) made hive-common in fe-connector-paimon-hive-shade, so maven-shade dropped it AND its transitive hadoop-client-api — the prior carrier of DistributedFileSystem. HMS-flavor catalogs (thrift metadata) and filesystem-on-S3 (hadoop-aws) were unaffected, which is why only hdfs filesystem catalogs broke. Add org.apache.hadoop:hadoop-hdfs-client (runtime, ${hadoop.version}) — it carries DistributedFileSystem + the hdfs FileSystem service registration and reuses the plugin's single hadoop-common FileSystem (hadoop-common excluded to keep exactly one copy — no cross-loader split). Same self-contained child-first pattern as hadoop-aws/hadoop-huaweicloud. Verified on the assembled plugin zip: DistributedFileSystem carriers=1, FileSystem.class carriers=1, hdfs service entry present. Also corrects the now-false pom comment claiming hadoop-client-api is transitively bundled.

      • The default endpoint is {@code https://storage.googleapis.com}, which usually does not need + * to be configured unless a custom domain is required.
        • + *
      • The region is typically not relevant for GCS since it is mapped internally by bucket, + * but may still be required when using the S3-compatible API.
        • + *
      • Access Key and Secret Key are not native GCS concepts. They exist here only for compatibility + * with the S3 protocol. Google recommends using OAuth2.0, Service Accounts, or other native + * authentication methods instead.
        • + *
      • Compatibility with older versions: + *
          + *
        • Previously, the endpoint was required. For example, + * {@code gs.endpoint=https://storage.googleapis.com} is valid and backward-compatible.
          • + *
        • If a custom endpoint is used (e.g., {@code https://my-custom-endpoint.com}), + * the user must explicitly declare that this is GCS storage and configure the mapping.
          • + *
        + *
        • + *
      • Additional authentication methods (e.g., OAuth2, Service Account) may be supported in the future.

`fe-connector-paimon/pom.xml`：加 `fe-property` compile 依赖（plugin-zip assembly 未排除 → 随 fe-foundation 一起 child-first 打包）。 +- `PaimonCatalogFactory.applyStorageConfig`：5 个 `applyCanonical*` 调用 → `StorageProperties.buildObjectStorageHadoopConfig(props).forEach(setter)`；删除 6 个 canonical 方法 + 全部别名数组/默认值/impl 常量 + 4 个仅 canonical 用的 helper（`firstNonBlankOrDefault/anyKeyStartsWith/containsToken/isClassAvailable`）。**文件 988→626 行（−362）**。保留 `firstNonBlank/nullToEmpty/USER_STORAGE_PREFIXES/FS_S3A_PREFIX`（透传/DLF/HMS 仍用）。 +- 新增 fe-property 入口 `StorageProperties.buildObjectStorageHadoopConfig(Map)`：只对象存储（跳过 HDFS/broker/local/http→避开 createAll 的默认 HDFS+checkHaConfig 抛错），无匹配返回空 map（不抛）。 + +**验收**：`PaimonCatalogFactoryTest` **60/60 绿**、fe-property `StoragePropertiesTest` 5/5 绿、`tools/check-connector-imports.sh` PASS、checkstyle 0、`mvn -pl :fe-connector-paimon -am package -Dassembly.skipAssembly=true` EXIT 0。（连接器 HiveConf

region/endpoint 必填抛 + ak/sk 一致性抛，并把 `fs.s3a.endpoint[.region]` 改**有值才发**（match 连接器宽松；conditional emit）。 + +**1 处 test 改（唯一反“保行为不变”的项，已在测试注释说明）**：`buildHadoopConfigurationEmitsCosRegionUnconditionally` 断言 `fs.cosn.bucket.region` 由 `""`→`ap-beijing`。原因=fe-property(=legacy) **从 `cos..myqcloud.com` 端点派生区域**（更正确），连接器旧 re-port 留空是简化；迁移后该 cosn catalog 得到正确区域（良性/更优）。 + +**M4 偏离记录（fail-loud，影响 fe-property 全体消费方）**：为对齐连接器宽松行为，fe-property 的 S3 兼容校验已**放宽**=不再因 region/endpoint 空而抛、不再强制 ak/sk 同设、endpoint/region 空则省略对应 fs.s3a key。这使 fe-property 比 legacy 宽松；未来 fe-core 迁入时若需严格校验需另行评估。 + +**仍未做**：① 引擎启动同步 `PropertyConfigLoader.hadoopConfigDir`/`AzureProperties.azureBlobHostSuffixes` 两静态（默认值对多数部署 OK）；② docker e2e（`enablePaimonTest=true`）验 minio/oss/s3/cos/obs/dlf paimon catalog 真实读 + plugin-zip 实际

ODPS。`bucket` 命中=MaxCompute tunnel 分片号，非存储桶 → 无重复 | + +**为什么**：这 4 个都是"直连活系统"连接器（ES / 关系库 / Trino / ODPS），数据不来自 S3/OSS 上的 parquet/orc 文件，所以从不构建 `fs.s3a.*` Hadoop storage config——这正是 paimon `applyStorageConfig` 那类重复的来源。`*ConnectorProperties` 都是纯连接器域常量持有类。 + +**真正会有该重复的是"读对象存储数据文件的湖仓连接器"**：paimon（已迁，本次）、以及 **hive / iceberg / hudi**（不在本次 4 个名单内，是后续 M-next 的候选；它们若有

`org.apache.doris.property[.storage|.common]`）；注册进 `fe/pom.xml` ``（fe-foundation 之后）+ dependencyManagement。 +- **M2 拷贝并重适配 storage**：24 个源文件搬入并改造（见 §3 改造清单）。 +- **M3 测试**：`StoragePropertiesTest` 5 用例（MinIO→fs.s3a.* 映射、MinIO→AWS_* 映射、S3 选型+URI 归一化、guessIsMe 顺序、HTTP 空配置）。 + +**验收证据：** +- `mvn -pl fe-property -am compile`：成功；**checkstyle 0**。 +- `mvn -pl fe-property -am

**配置产物 Configuration → Map**：`Configuration hadoopStorageConfig` → `Map hadoopConfigMap` + `getHadoopConfigMap()`；所有 `conf.set` → `map.put`；FS impl 全是字符串字面量（无 hadoop 类型）。null map = 该后端无 hadoop 配置（如 HTTP），保留旧 skip 语义。 +3. `UserException`(fe-common) → `StoragePropertiesException`(fe-foundation，unchecked)；S3URI 的 `new UserException(throwable)` → `(msg, cause)`。 +4. **S3Properties 剥离 fe-core 云/存储策略机器**：删 `getObjStoreInfoPB`(proto)、`getS3TStorageParam`(thrift)、`getCredProviderTypePB/getTCredProviderType`、`requiredS3Properties/checkRequiredProperty/requiredS3PingProperties/convertToStdProperties/optionalS3Property`(DdlException)、`getAwsCredentialsProvider V1/V2`(aws-sdk)、`Env` 内类 + 云常量。连接器自行用自带 SDK 构造凭据/PB。 +5. `getAwsCredentialsProvider`(aws-sdk) 从 AbstractS3Compatible + OSS/COS/OBS/GCS 移除；保留类型化凭据 getter + `AwsCredentialsProviderMode` 枚举（纯枚举）。 +6. **HdfsProperties/HdfsCompatibleProperties 去鉴权对象**：删 `HadoopAuthenticator` 构造 + `hadoopAuthenticator` 字段/getter（鉴权是连接器/引擎职责，走 `ConnectorContext.executeAuthenticated`）；HDFS 仍解析 kerberos 属性进 map。 +7. **fe-common Config 解耦**：`Config.hadoop_config_dir` → `PropertyConfigLoader.hadoopConfigDir`（可设静态，默认 `$DORIS_HOME/plugins/hadoop_conf/`）；`Config.azure_blob_host_suffixes` → `AzureProperties.azureBlobHostSuffixes`（可设静态，内联默认 8 项）。 +8. **loadConfigFromFile 保留并迁移**：新建 `PropertyConfigLoader`（hadoop `Configuration` 解析 XML，**hadoop-common=provided**）；`ConnectionProperties.loadConfigFromFile` 改用它，仍返回 Map。 +9. `HdfsClientConfigKeys`（hadoop-hdfs-client）4 常量内联进 HdfsPropertiesUtils。 +10. `S3URI` 拷入 `org.apache.doris.property.storage`。 +11. `HttpProperties` 误引 `org.apache.hudi...MapUtils` → `commons-collections4.MapUtils`（`isNullOrEmpty`→`isEmpty`）。 + +## 4. 偏离设计/需注意（fail-loud） + +- **hadoop-common 是 provided（非"零 hadoop"）**：设计文档曾期望零 hadoop；因首期纳入 `loadConfigFromFile`（须 hadoop 解析 XML 配置文件）而保留为 provided。**仍满足硬约束**（不进 jar，已验证）。唯一 hadoop 用处=`PropertyConfigLoader`/`loadConfigFromFile`；其余全 hadoop-free。若要彻底零 hadoop，可把 loadConfigFromFile 改注入式 loader（引擎提供）。 +- **S3 v2 凭据版本开关未移植**：`S3Properties.initializeHadoopStorageConfig` 只发默认(v1)assumed-role 配置（provider 类用 FQN 字符串硬编码）。`Config.aws_credentials_provider_version=v2` 的分支属 fe-core Config 行为，连接器场景不适用。 +- **引擎需在启动时同步两个可设静态**（否则用默认值）：`PropertyConfigLoader.hadoopConfigDir = Config.hadoop_config_dir`、`AzureProperties.azureBlobHostSuffixes = Config.azure_blob_host_suffixes`。首期未接（默认值对绝大多数部署正确）。 +- **S3Properties 剥离的云/存储策略方法**：仅 fe-core legacy 调用，连接器不需要；保留在 fe-core 旧类（并存）。 + +## 5. 下一步（M4：paimon 连接器迁移，strangler-fig 阶段2） + +1. `fe-connector-paimon` pom 加 `fe-property` 依赖；plugin-zip assembly include `fe-property`（纯小 jar）。 +2. `PaimonCatalogFactory`：删 `applyStorageConfig`/`applyCanonicalMinioConfig`/OSS/COS/OBS 块/`MINIO_*_ALIASES` 重抄段，改 `StorageProperties.create(props).getHadoopConfigMap().forEach(conf::set)`。 +3. `tools/check-connector-imports.sh` 通过（fe-property 在允许包根）。 +4. paimon minio/oss/s3 回归（`external_table_p0/paimon`）证明重复消除 + 无行为回归。 +5. 引擎启动期同步 §4 的两个静态。 +6.（可选）更全的逐后端平价 sweep：新 `getHadoopConfigMap()`/`getBackendConfigProperties()` vs

**compile**：`fe-foundation`（`${project.version}`）、`commons-lang3`、`guava`、`log4j-api`。 +- **可选 provided**：`hadoop-hdfs-client`（仅 `HdfsPropertiesUtils` 用 `HdfsClientConfigKeys` 的 4 个常量；二选一：①`provided`（不打包）；②直接内联这 4 个 key 字符串，连这个依赖都省掉——**推荐内联**，使新模块零 hadoop 依赖）。 +- **无** hadoop-common / aws-sdk / iceberg / paimon / fe-common / fe-thrift / fe-grpc。 +- `fe/pom.xml`：`` 加

`provided` 排除技巧。 + +## 9. 与现有 `ConnectorContext` 桥的关系 + +fe-core 现已在 `ConnectorContext` 暴露 `getBackendStorageProperties()` / `normalizeStorageUri()` / `vendStorageCredentials()`——让连接器"回调引擎做归一化"以绕开 import-gate。`fe-property` 让连接器**直接做**归一化（无需回调引擎），未来可逐步替代这些桥方法（含 vended：把 per-table token map 直接喂 `StorageProperties.create`）。**本期不动这些桥**，仅新增 fe-property 并迁移 `applyStorageConfig` 重抄段；桥方法待全面迁移后再评估下线。 + +## 10. 边界与坑（Edge Cases） + +1. **`S3URI`**：旧 `S3PropertyUtils` 依赖 fe-core 的 `common.util.S3URI`。新模块**拷贝** `S3URI` 进 `org.apache.doris.property.storage`（纯 java，仅把 UserException 换 StoragePropertiesException）。 +2. **HdfsClientConfigKeys**：见 §8，推荐内联 4 个 key 常量，避免 hadoop 依赖。 +3. **Azure OAuth**：旧 `AzureProperties` OAuth 分支构造 `Configuration`；新版产出 `fs.azure.account.oauth.*` Map。 +4. **鉴权（kerberos）**：旧 `HdfsProperties` 构造 `HadoopAuthenticator`（fe-common）。新版**只解析**鉴权属性（auth type / principal / keytab / 归一化 hadoop.* Map），**不构造** authenticator——authenticator 是运行时对象，由连接器/引擎（`ConnectorContext.executeAuthenticated`）负责。借此甩掉 fe-common 依赖。 +5. **`guessIsMe` 选型顺序**：MinIO 让位 Azure/COS/OSS/S3 的探测顺序需原样保留（否则误判后端）。 +6. **`HttpProperties` 误引**：旧版误 import `org.apache.hudi...MapUtils`；新版改 commons-collections4，避免拖 Hudi。 +7. **凭据 provider 构造下移**：`AwsCredentialsProviderFactory`（aws-sdk）不进 fe-property；连接器需要 provider 时自建（多数场景连接器只需把 Map 灌 Configuration / 发 BE，并不需要 provider 对象）。 + +## 11. 测试与回滚 + +- **平价测试（关键）**：对每个 storage 子类，用同一组 raw props 跑"新 `getHadoopConfigMap()`/`getBackendPropertiesMap()`" vs "旧 `getHadoopStorageConfig()` 转成 Map / `getBackendConfigProperties()`"，断言**键值完全一致**（含 minio/oss/cos/obs/azure/hdfs）。这是防漂移的核心闸。 +- **单元测试**：选型 `guessIsMe` 顺序、URI 归一化、ParamRules 校验、各 alias 解析、minio.* 专属前缀检测。 +- **连接器迁移验证**：paimon 改用 fe-property 后，跑 `external_table_p0/paimon` 回归（minio/oss/s3 catalog 读）。 +- **回滚**：strangler-fig 天然可回滚——任一连接器迁移出问题，单独回退该连接器到旧 `applyStorageConfig`，fe-property 与旧 property 并存互不影响。 + +## 12. 风险与备选 + +- **风险1：平价漂移**。新 Map 推导若与旧 Configuration 落键有差→连接器/BE 行为变。缓解=§11 平价测试逐键断言；首迁 paimon 用真实 minio/oss 回归。 +- **风险2：代码拷贝双维护**。并存期 storage 逻辑两份。缓解=并存窗口尽量短、优先迁 paimon 验证范式、平价测试钉死一致；新代码为权威，旧代码进入"只读冻结"。 +- **风险3：plugin-zip 漏打 fe-property**。缓解=迁移连接器时同步改 assembly，加一条 smoke（plugin 加载 `org.apache.doris.property.storage.StorageProperties` 不 ClassNotFound）。 +- **备选A（被否）**：原地 lift-and-shift 整个 datasource.property → 循环依赖 + vendored glue + 重型 SDK，已证不可行（见前置研究报告）。 +- **备选B**：把新代码直接塞进 fe-foundation。否决——会破坏 fe-foundation 零依赖基座（即使首期 storage 很轻，后续 metastore 会重）。保持 fe-foundation 为纯基座，fe-property 为其上一层。 + +## 13. 有序 TODO 列表 + +**M1 — 模块骨架** +1. 新建 `fe/fe-property/pom.xml`（仿 fe-foundation；compile=fe-foundation+commons-lang3+guava+log4j-api）。 +2. `fe/pom.xml` `` 加 `fe-property`（fe-foundation 后）；dependencyManagement 加条目。 +3. 建包 `org.apache.doris.property.storage`（+ `storage` 内 util）。 + +**M2 — 拷贝并重适配 storage（核心）** +4. 拷贝 `ConnectionProperties`（基类，去掉 `loadConfigFromFile` 对 fe-common 的依赖或改

`buildHadoopConfigMap()`、`UserException`→`StoragePropertiesException`、`getBackendConfigProperties`→`getBackendPropertiesMap`。 +6. 拷贝 `AbstractS3CompatibleProperties` + `ObjectStorageProperties` + `Abstract*`：移除 `getAwsCredentialsProvider()`（aws-sdk），改产出凭据 getter；S3 系 fs.s3a.* 改写进 Map。 +7. 拷贝 13 个具体类（S3/OSS/COS/OBS/MinIO/GCS/Ozone/Hdfs/OSSHdfs/Azure/Broker/Local/Http）：逐个把 `conf.set(...)` 改为 `map.put(...)`；保留 `guessIsMe` 顺序；修 HttpProperties 的 hudi 误引。 +8. 拷贝 util：`S3PropertyUtils`、`HdfsPropertiesUtils`（内联 `HdfsClientConfigKeys` 4 常量）、`AzurePropertyUtils`、**`S3URI`**（新拷贝）、`exception/AzureAuthType`。 +9. 移除 `S3Properties` 的 proto/thrift 方法（不移植）。 + +**M3 — 测试** +10. 平价测试：每个子类新 vs 旧逐键断言（依赖 fe-core 旧类做基准，可放 fe-property 的 test 或一个临时对照 test）。 +11. 单元测试：guessIsMe 顺序、URI 归一化、minio.* 检测、ParamRules、alias。 +12. checkstyle 0 告警。 + +**M4 — 首个连接器迁移（paimon，验证范式）** +13. `fe-connector-paimon` 加 `fe-property` 依赖；plugin-zip assembly include fe-property。 +14. `PaimonCatalogFactory`：删 `applyStorageConfig`/`applyCanonicalMinioConfig`/OSS/COS/OBS 块/`MINIO_*_ALIASES`，改为 `StorageProperties.create(props).getHadoopConfigMap().forEach(conf::set)`。 +15. 跑 import-gate（`tools/check-connector-imports.sh`）确认无违规；跑 paimon 回归（minio/oss/s3）。 + +**M5 — 文档与收尾** +16. 更新

import 这些重型 SDK，并且 import 了 fe-core 的 `IcebergExternalCatalog/PaimonExternalCatalog/DLFCatalog`——而这三个类又**反向 import 了 property 包**，构成 Maven 无法接受的循环依赖；此外 Glue 客户端是**以源码形式 vendored 在 fe-core 里**（38 个

个（`common.util.S3URI`，自包含工具类，下沉即可），重型依赖只剩 hadoop + aws-sdk，可用 `provided` scope 排除出最终 jar。 | +| **重依赖如何不进最终 jar？** | 用 `provided`（编译期可见、不打包）。这正是用户的硬约束所要求的，且 fe-core 与各 SPI 插件运行时本就自带 hadoop/aws，late-binding 天然成立。 | +| **该并入现有 `fe-foundation` 吗？** | **不该**。`fe-foundation` 的 pom 只依赖 `fastutil-core`，零重依赖是它的立身之本（被 fe-catalog、fe-filesystem、SPI 插件当"轻基座"依赖）。塞入 hadoop/aws 会污染所有下游。应新建 `fe-property` 模块，依赖 `fe-foundation`。 | + +**一句话**：用户"把属性解析做成可复用 module"的诉求，对**最有复用价值的对象存储（storage）解析**是成立且推荐的——这恰好就是 minio 那个修复（`PaimonCatalogFactory` 重写 minio.* 解析）本应复用的部分；但 `metastore`（catalog

metastore 的 `*Properties` 本身就是 catalog 构造层（`AbstractIcebergProperties.initCatalog():Catalog`、`AbstractPaimonProperties.initializeCatalog():Catalog`），**直接 import 并 new iceberg/paimon catalog**，不止 `DLFCatalog` 一处。所以"只上提常量+反转 DLFCatalog"并不能让整包摆脱重型 SDK。→ **正确做法是不搬 metastore。** +2. **Glue 是 vendored 源码（38 文件）而非依赖——证实。** `HiveGlueMetaStoreProperties` import 的 `com.amazonaws.glue.catalog.util.AWSGlueConfig` 在整个仓库只存在于 fe-core.jar；无 `provided` 坐标可加。→ **又一条 metastore 必须留在 fe-core 的硬理由。** +3. **循环依赖（catalog 类反向 import property 包）——证实**（见 4.3）。 + +这些修正不削弱"storage 子集可抽出"的结论，反而把"metastore 不可抽出"钉死，使最终方案更清晰。 + +--- + +## 6. 推荐方案 + +### 6.1 新建 `fe-property` 模块，抽出"干净子集" + +**搬入 `fe-property` 的内容（约 25 文件）：** +- `storage/*`（20）+ `storage/exception/*`（1） +- `common/AwsCredentialsProviderFactory.java`、`common/AwsCredentialsProviderMode.java`（2，零 iceberg） +- `constants/*`（3） +- `ConnectionProperties.java`（1） + +**留在 fe-core 的内容：** +- `metastore/*`（28）—— 循环依赖 + vendored glue + 直接构造 iceberg/paimon catalog +- `fileformat/*`（12）—— 无重依赖、却深耦合 thrift/nereids/analysis/qe，搬迁无收益 +- `common/IcebergAwsClientCredentialsProperties.java`、`common/IcebergAwsAssumeRoleProperties.java`（2，import iceberg，仅被 metastore 用） + +### 6.2 搬迁前置改造（precondition fixups） + +1. **下沉 `S3URI`**：把 `common.util.S3URI`（403 行，自身仅依赖 UserException）移到 `fe-property`（或 fe-common）。这是 storage 唯一的 fe-core 反向依赖，移走后 storage 对 fe-core 零依赖。 +2. **避免 split-package**：`property.common` 若一半在 fe-property、一半在 fe-core，会造成同一个包跨两 jar（JVM/Maven 不允许）。解法：把 2 个 iceberg-aws 辅助类从 `property.common` **挪进 `property.metastore`**（它们只被 metastore 用），使 `property.common` 整体进入 fe-property。 +3. **修正 `HttpProperties` 的误引**：它 import 了 `org.apache.hudi.common.util.MapUtils`（同级 `LocalProperties` 用的是 commons-collections4）。这会把 Hudi 拖进新 module，应改回 commons-collections4。 + +### 6.3 `fe-property` 的 pom 模板（仿 fe-catalog，重依赖翻成 provided） + +- parent=`fe`（version=`${revision}`），packaging=jar，finalName=`doris-fe-property`，test-jar、javadoc skip、release source профиль——照抄 fe-catalog。 +- **compile

jar）**：`hadoop-common`、`hadoop-hdfs-client`、`hadoop-aws`、`software.amazon.awssdk:{auth,sts,regions,s3,s3tables}`。**无需 iceberg/paimon/hive/glue/dlf**（都随 metastore 留在 fe-core）。 +- **建议加 fe-connector 式的 import-gate**（exec-maven-plugin，validate 阶段）禁止 `fe-property` import `org.apache.doris.datasource.{iceberg,paimon}` 及 fe-core 内部包，防止循环依赖复发。 + +### 6.4 构建顺序与消费 + +- 在 `fe/pom.xml` 的 `` 中把 `fe-property` 放在 `fe-foundation/fe-common/fe-thrift/fe-grpc/fe-catalog` 之后、`fe-core` 之前（Maven 实际按依赖图排序，列表顺序对齐即可）；在 parent dependencyManagement 加 `fe-property` 条目。 +- `fe-core/pom.xml` 增加一条对 `fe-property` 的 compile 依赖；删除已搬走的源码。fe-core 运行时本就带 hadoop/aws，`provided` 依赖透明解析。 +- **保持 FQN 不变**（`org.apache.doris.datasource.property.storage/common/constants`）：由于每个叶子包整体只落在一个 jar（storage/common/constants→fe-property，fileformat/metastore→fe-core，无包被劈开），fe-core 里 metastore/fileformat 对已搬类的 import **无需改动**，仅物理移动文件。 + +--- + +## 7. 风险与坑 + +1. **hive-catalog-shade / paimon-hive-shade 版本耦合**：`HiveConf`、DLF、iceberg-hive、paimon-hive 在 fe 里运行时来自**relocate/shade** 的制品（HMS 钉 2.3.7、thrift relocate、内嵌远古 fastutil）。本方案把这些**全留在 fe-core**，规避了该坑；若将来要搬 metastore 必须正面处理。 +2. **vendored Glue 源码（38 文件）**：`metastore` 留在 fe-core 即可继续编译；不可低估其搬迁成本。 +3. **`S3URI` 下沉**：需确认其无其它 fe-core 专属依赖（初查仅 UserException，干净）。下沉后 fe-core 内其它调用方自动从下层 module 解析（fe-core 仍依赖 fe-property，无碍）。 +4. **`ConnectContext` 反转**：`fileformat` 留在 fe-core，本次不涉及；仅当未来要抽 fileformat 时才需做 SessionFlags 接口反转。 +5. **fe-thrift / fe-grpc 是真实编译依赖**（S3Properties 用 `TS3StorageParam/TCredProviderType` + `cloud.proto.Cloud`），不是可选项，pom 必须显式声明。 +6. **`provided` 的运行时契约**：消费方（fe-core、以及将来若依赖它的 SPI 插件）**必须**自带 hadoop/aws。fe-core 满足；SPI 插件本就 child-first 自带 hadoop/aws（见历史 RC-3 self-contained bundling），也满足。 + +--- + +## 8. 工作量与分阶段路径 + +| 阶段 | 内容 | 规模 | +|---|---|---| +| P1 | 前置改造：下沉 `S3URI`；2 个 iceberg-aws 类从 common 挪进 metastore；修 `HttpProperties` 的 hudi 误引 | 小（~5 文件） | +| P2 | 新建 `fe-property` module +

fe/fe-property -am package` 成功； +- `unzip -l fe/fe-property/target/doris-fe-property.jar` **不含** `org/apache/hadoop/**`、`software/amazon/**`、`org/apache/iceberg/**`、`org/apache/paimon/**`、`com/amazonaws/**`； +- fe-core 全量编译通过、storage 相关 UT 全绿； +- fe-connector（或任一 fe-core 之外的 module）能成功 `compile` 依赖 `fe-property` 并调用 `StorageProperties.createAll(...)`（验证"可复用"目标达成）。 + +--- + +## 9. 总结 + +- 用户的设想**部分成立且值得做**：最具复用价值的**对象存储/HDFS/Azure 属性解析（storage）** 是**可干净抽出**的——它零 iceberg/paimon 依赖、对 fe-core 仅 1 处易解的反向依赖、重依赖仅 hadoop+aws 且可 `provided` 排除出 jar。抽出后，fe-connector 等 module 即可复用，**正好消除 minio 那类"在连接器里重写属性解析"的重复**。 +- 但**"把整个 `property/` 搬出"不可行**：`metastore` 子包是 catalog 构造层，直接 new iceberg/paimon/hive/glue/dlf 客户端、import 重型 SDK、依赖 vendored Glue 源码，并与 fe-core 的 `*ExternalCatalog` 构成**循环依赖**。它本质是 fe-core/连接器领域逻辑，不是"通用属性解析"，应留在 fe-core。`fileformat` 无重依赖但深耦合 thrift/nereids/qe，搬迁无收益，亦留在 fe-core。 +- **推荐**：新建 `fe-property`（依赖 fe-foundation，**不并入** fe-foundation 以免污染其零依赖基座），抽 `storage + common(纯AWS) + constants + ConnectionProperties`，重依赖 `provided`，加 import-gate 防循环复发。中等工作量，风险可控。 From 5bf6ceee39662549e368476c8a8472956a004f9c Mon Sep 17 00:00:00 2001 From: morningman Date: Wed, 17 Jun 2026 13:26:15 +0800 Subject: [PATCH 075/128] [P0-T01] storage-refactor: recon verdict + DV-001/D-009 (bind-all mechanism) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase P0+P1 (paimon storage 收口) approved. P0-T01 recon (4-agent + direct read) over the three StorageProperties trees + connector seam: - F1 (equivalence, non-blocking): fe-filesystem toHadoopConfigurationMap() / toMap() match the fe-property path paimon uses today on the common static-credential case for every backend (COS identical; OSS/OBS identical incl jindo/cosn/obs blocks); fe-filesystem is a superset (S3 assume-role/anon; OSS/COS/OBS endpoint/region unconditional vs lenient). Treat fe-filesystem as the new source of truth; T1 pins the common case + documents the additive diffs. - F2 (feasibility, blocker): no raw map -> List binder exists (provider registry private, only first-match createFileSystem). So getStorageProperties() cannot be confined to DefaultConnectorContext -> falsifies the design's P0-1 expectation and the "single fe-core change" whitelist. Recorded DV-001; user chose mechanism A -> D-009: add additive FileSystemPluginManager. bindAll(Map); getStorageProperties() obtains the raw map via the existing supplier's getOrigProps() (no construction-site change). Wrote back: design §4 P0-1/P0-2 + §2.1, WORKFLOW §4.1 whitelist (+1 FileSystemPluginManager.java), decisions D-009, risks R-004, tasks P0-T01(done)/P0-T02/P1-T02, PROGRESS, HANDOFF. No code yet.

`ConnectorContext.getStorageProperties()`（返回 fe-filesystem typed `StorageProperties`）所需的 raw map → `List` 绑定，落在 fe-core `FileSystemPluginManager` 新增 additive `public List bindAll(Map)`（镜像现有 `createFileSystem` 的 provider 循环，但用 `provider.bind(props)` 全量收集所有 `supports()` 命中者，而非首个命中 `create`）。`DefaultConnectorContext.getStorageProperties()` 调它；raw map 经现有 `storagePropertiesSupplier` 值的

必须套**后端特定**默认值（region/endpoint 推导、S3=50/3000/1000 vs OSS/COS/OBS=100/10000/10000 调优分叉），需 storage providers（ServiceLoader 发现）；而连接器按 D-003 **只见 fe-filesystem-api 接口、不持有 providers**，物理上无法独立完成全程归一。延续 D-003「动态/provider 发现留 fe-core」的精确边界：连接器最轻、归一单点、无漂移。**备选 B（放宽红线让连接器依赖 fe-filesystem-spi/providers 自做端到端）被否**：加重连接器 classpath + 破坏「fe-connector 仅依赖 fe-filesystem-api」红线。 +- **影响**：设计 §2.3（细化边界）；tasks

**内容**：新建叶子模块 **`fe-kerberos`**（依赖**仅** hadoop-auth/hadoop-common；把唯一外部依赖 trino `KerberosTicketUtils` 用 JDK `javax.security.auth.kerberos` 替掉），把 fe-common `org.apache.doris.common.security.authentication.*` 整套搬入作**唯一真相源**；`fe-filesystem-hdfs` **删掉自有的** `KerberosHadoopAuthenticator`、改依赖 fe-kerberos；统一两个打架的 `HadoopAuthenticator` 接口（fe-common 用 `PrivilegedExceptionAction` vs fe-filesystem-spi 用 `IOCallable`）为单接口 + 消费侧 adapter。`fe-common`/`fe-core`/`fe-filesystem-*`/`fe-connector-*` 共用。`fe-kerberos` **置于顶层**（与 `fe-foundation`/`fe-common` 平级的中立叶子），无环。 +- **归属/命名（用户 2026-06-17 二次确认）**：**否决** `fe-connector-auth`（置于 fe-connector 组）——会破坏两条规则：(1) `fe-filesystem-* ──╳──► fe-connector` gate（fe-filesystem-hdfs 无法依赖它删除自有副本）；(2) `fe-common`（低层）反向依赖 fe-connector 子模块=层级倒挂。故必须是**顶层中立叶子**才能被 fe-filesystem-hdfs + fe-common 共用（=满足原始需求「HMS 与 HDFS 都能用」）。**模块名定 `fe-kerberos`**（用户 2026-06-17 确认）。 +- **理由**：现状 kerberos **三处实现**——(1) fe-common `security.authentication.*`（fe-core/HMS/HDFS 用）；(2) fe-filesystem-hdfs **自抄一份** `KerberosHadoopAuthenticator`（为避免依赖 fe-common，一年前拷贝、TGT 刷新可能已漂移）；(3) paimon 手抄 HMS 的 kerberos HiveConf 键 + 回调 `ctx.executeAuthenticated`。改一处要改三处。auth 类 import 干净（仅 JDK/hadoop/log4j/commons/guava + 1 个 trino），fe-common 不依赖 fe-core → 抽取无阻力；`fe-foundation` 现为纯净（零 hadoop）的 `@ConnectorProperty` 叶子，**不应**被 hadoop 污染（故否「折进 fe-foundation」）；也否「fe-filesystem/fe-connector 直接依赖较重的 fe-common」。 +- **范围（分两步，用户 2026-06-17 确认）**：(a) **P3a 纳入本次** = 先建 `fe-kerberos` + 让 **paimon** 的 HMS kerberos facts 走它（paimon-local、纯新增，**不碰** fe-common/fe-filesystem-hdfs 既有路径，符合 D-005）；(b) **P3b = follow-up（本次不做）** = 全量去重（删 fe-filesystem-hdfs 副本、fe-common 重指向 fe-kerberos、统一两个 `HadoopAuthenticator` 接口），与 hive/iceberg 迁移同批——此步改 fe-common + fe-filesystem-hdfs，超出 D-005，故独立。 +- **影响**：设计 §3.5（新增 Kerberos 节）+ 依赖图（加 fe-kerberos 叶子）；tasks 新增 P3；risks 补「kerberos 三处漂移」项。 + +## D-006 — MetaStore 后端「类型」用

一句话结论（TL;DR） + +**新模型在“架构解耦”上是教科书级别的（纯 JDK 的 api 层、零 fe-core 回边、按 provider 拆模块、运行期插件加载），但在“是否真正被使用”上目前是休眠（dormant）状态——`fe-core` 对新 `filesystem.properties.*` 的引用为 0，线上链路仍然走旧的胖类模型经 `StoragePropertiesConverter` 拍平成 `Map` 的老路。** 因此： + +- 解耦/分层质量：高（9/10 级别）。 +- 接口命名与一致性：偏低（4/10）——三处同名 `StorageProperties`、双接口冗余、能力模型与类型枚举尚无消费者。 +- 迁移完整性：很低（3/10）——“删除 fe-core 的 StorageProperties”短期不现实，被 83 个调用方 + 转换桥 + 40 处 BE/Hadoop 配置生成点阻塞。 + +> **重要澄清（与提问表述的偏差，按事实修正）** +> 1. 这并不是一次简单的“搬家”。新的 `fe-filesystem` 版本是**重新设计**：旧 `StorageProperties` 是 `abstract class`，新 `StorageProperties` 是 `interface`，形状与职责都不同。 +> 2. 仓库里**同时存在三套**“StorageProperties”：旧的 `fe-core`（在用）、本次新增的 `fe-filesystem`（休眠）、以及给 paimon 用的 `fe-property` 模块里的近似拷贝（commit `70e934d`，与 fe-core 版本逐字不同）。删除 fe-core 版本前，必须先把这三套理清楚。详见 §7。 + +--- + +## 1. 背景与动机 + +PR #63400 的目标是：**不再假设所有对象存储都能永久地通过 AWS S3 兼容协议访问**。动机（摘自 commit message）： + +- AWS S3 SDK v2 2.30+ 行为变更，国产云厂商适配滞后； +- 旧版 AWS SDK 有 CVE，不可长期停留； +- Catalog FileIO 依赖 Hadoop，而 Hadoop 3.4 停维、3.5 又抬高了 AWS SDK 的最低版本要求，会反向逼迫 Doris 升级 SDK； +- OBS 私有化部署 / OBS 并行文件系统在 S3 兼容语义下出现签名错误，必须使用厂商原生 SDK。 + +为此该 PR 在 FE 侧引入了一套“原生 SDK 对象存储” SPI：`S3FileSystem` 保留对象存储的通用文件语义，具体 I/O 下沉到各厂商的 `ObjStorage` 实现；同时**顺带引入了一套全新的、provider 自持的、强类型存储属性模型**——这正是本报告关注的 `StorageProperties` / `FileSystemProperties` 体系。 + +本次 commit 共改动 **89 个文件**，但对 `fe-core` 的侵入很小（见 §6）：核心的新增内容都落在 `fe/fe-filesystem/` 的多模块树里。 + +--- + +## 2. 旧模型：`fe-core` 的胖抽象类体系 + +位置：`fe/fe-core/src/main/java/org/apache/doris/datasource/property/storage/` + +### 2.1 结构 + +```

Hadoop `Configuration`，相对好搬。 + +> 值得一提的是：**这套模型并不走 GSON 持久化**。`GsonUtils` 没有为 `ConnectionProperties`/`StorageProperties` 注册任何适配器；`CatalogProperty` 只持久化原始的 `@SerializedName("properties")` map，typed 列表是 `volatile`/transient 的，按需通过 `createAll` 重建。**所以删除旧类没有元数据格式迁移成本**——阻塞点纯粹在编译期调用方，不在持久化。 + +--- + +## 3. 新模型：`fe-filesystem` 多模块体系 + +### 3.1 模块与依赖方向（已 `grep` 核验，无环、单向） + +``` +fe-foundation (叶子模块:

Mirrors the existing createFileSystem provider loop but uses provider.bind() to collect ALL supporting providers' typed props (not first-match create()), matching legacy StorageProperties.createAll's one-entry-per-backend shape. Migrated providers (S3/OSS/COS/OBS/Azure) override bind(); legacy ones (HDFS/broker/local) inherit the default bind() that throws UnsupportedOperationException -> bindAll skips them (they contribute no typed props; the connector covers those via raw fs./dfs./hadoop. passthrough). Real provider validation errors propagate (fail-loud). TDD: 4 new tests in FileSystemPluginManagerTest pin the contract (collect-supporting / skip-non-supporting / skip-legacy-no-bind / empty); RED (5 errors on a throwing stub) -> GREEN (5/5). checkstyle 0. +34 lines, purely additive (no existing method touched). fe-core legacy datasource.property.storage package + all fe-filesystem modules untouched. Note (for P1-T02): real object-store providers are runtime directory plugins (Env.loadPlugins), not on fe-core's unit-test classpath, so the real-provider end-to-end path is covered by P1-T06 (docker). Also, getStorageProperties() will need the LIVE plugin-loaded manager (FileSystemFactory.pluginManager, currently private/no getter) -> P1-T02 needs a FileSystemFactory static accessor (3rd fe-core file).

FileSystemFactory.bindAllStorageProperties(rawMap): static accessor that reaches the LIVE plugin-loaded FileSystemPluginManager (object-store providers are runtime directory plugins, absent from a fresh manager), or falls back to ServiceLoader when uninitialized -- mirrors getFileSystem's existing dual path. This is the 3rd (and final) additive fe-core file the mechanism needs; the construction site is untouched (R-004). - DefaultConnectorContext.getStorageProperties(): sources the full catalog raw map from the existing storage supplier's getOrigProps() (verified: StorageProperties.createAll passes the whole map to every parsed instance), then binds via the factory. Empty supplier (REST-vended / non-plugin / credential-less) -> empty list, correct parity. Mechanism A, user-confirmed twice (D-009 + its 2026-06-17 "2->3 files" refinement). All 3 fe-core touch points (DefaultConnectorContext, FileSystemPluginManager, FileSystemFactory) are purely additive. TDD: 4 new tests pin the contract -- factory delegate-to-live-manager / ServiceLoader-fallback; ctx empty-supplier / full-binding-captures-the-raw- map (proving getOrigProps extraction). RED (stub UOE / NPE) -> GREEN 4/4.

The connector-local overlay (paimon.* re-key + raw fs./dfs./hadoop. passthrough, last-write-wins) and the kerberos-after-storage ordering in buildHmsHiveConf are preserved. PaimonConnector.buildStorageHadoopConfig() assembles the map from ctx.getStorageProperties().toHadoopProperties().toHadoopConfigurationMap(); REST ignores it. fe-property import removed (pom dep kept for P1-T05, DV-003-b); fe-filesystem-api added as a direct dependency. HMS 1/2/3-arg overloads collapsed to a single explicit 3-arg builder. Tests: ~23 canonical-translation UTs removed (now fe-filesystem's job, covered by its *FileSystemPropertiesTest); 6 connector-contract UTs added (storage-map overlay x3 builders + explicit-fs.s3a-overrides-storage + paimon-prefix-overrides-storage + kerberos-survives-storage-overlay). paimon module 292/0/0 (1 docker-gated skip), checkstyle 0, connector import-gate PASS. T1 equivalence = Option C (DV-003): connector-local contract UT + docker P1-T06 gate, because fe-filesystem object-store impls are runtime-only plugins absent from every unit-test classpath. Adversarial review wf_76df09a4-c2f (8 agents) refuted a false BLOCKER + 2 MAJORs and confirmed R-006: the S3/OSS/COS/OBS tuning defaults (50/3000/1000, 100/10000/10000) lack an explicit UT guard in fe-filesystem (functionally correct, docker-backstopped; fe-filesystem test follow-up is out of the P1 whitelist). e2e/docker NOT run.

From 60c6a50bb6e43efd361a6a307b3ee88530564a7b Mon Sep 17 00:00:00 2001 From: morningman Date: Wed, 17 Jun 2026 21:34:39 +0800 Subject: [PATCH 082/128] [P1-T04] fe-connector-paimon: BE static creds via ctx.getStorageProperties().toBackendProperties() (typed fe-filesystem seam) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Switch PaimonScanPlanProvider's BE static-credential emission from the legacy ctx.getBackendStorageProperties() seam to iterating the typed fe-filesystem ctx.getStorageProperties() and merging each toBackendProperties().toMap() into location.* scan props. Vended overlay unchanged and still applied after (vended overlays static). Per user decision: full switch, accepting the HDFS BE regression — fe-filesystem has no typed HDFS BE model yet (HdfsFileSystemProvider throws on bind, bindAll skips it), so getStorageProperties() yields no HDFS entry and the hadoop/dfs/HA/ kerberos keys that became THdfsParams are dropped. Recorded as DV-004 / R-007 with follow-up FU-T01 (add fe-filesystem HdfsFileSystemProperties). Note: this switch is NOT required by P1-T05 (getBackendStorageProperties is a ConnectorContext seam, not a fe-property dependency); it is the D-003 uniform-typed-consumption goal. Adversarial review (wf_09745716-d48, 10 agents) confirmed R-008: typed OSS/COS/OBS models omit AWS_CREDENTIALS_PROVIDER_TYPE (legacy emitted ANONYMOUS for credential- less catalogs) -> follow-up FU-T02. Three test-gap findings fixed by a new test covering the .ifPresent skip + multi-entry merge. paimon module 292/0/1skip, PaimonScanPlanProviderTest 52/0, checkstyle 0, import-gate PASS, whitelist clean. docker e2e NOT run.

[PATCH 083/128] [P1-T05] fe-connector-paimon: drop the fe-property dependency edge MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove the fe-property block from fe-connector-paimon/pom.xml. The import/call were already removed in P1-T03 (DV-003-b), so this is the pom edge only. The fe-property module itself is NOT deleted (D-005) — it simply becomes a zero-consumer orphan. Verification (the gate IS the build — no unit test to write): full paimon module compiles and all tests stay green (293/0/1skip, incl. P1-T04's added test), proving no hidden transitive reliance on fe-property; paimon now depends only on fe-connector-{api,spi} + fe-filesystem-api + fe-thrift (provided) + paimon SDK + hive-shade. grep org.apache.doris.property over paimon src == 0, no fe-property artifact in the pom, checkstyle 0, import-gate PASS, whitelist clean (pom only). docker e2e NOT run. This formally severs paimon's storage edge to fe-property; P1 storage consolidation now only has P1-T06 (verification) remaining.

[FU-T01] fe-filesystem-hdfs: HDFS typed BE model restores HDFS BE keys (R-007) P1-T04 switched paimon's BE static-credential path fully to the typed getStorageProperties().toBackendProperties().toMap() seam, but fe-filesystem had no HDFS typed BE model (HdfsFileSystemProvider.bind() threw -> bindAll skipped it), so HDFS-warehouse catalogs lost their hadoop/dfs/HA/kerberos BE keys -> THdfsParams (DV-004 / R-007). Add HdfsFileSystemProperties (FileSystemProperties + BackendStorageProperties, BE-only) whose toMap() faithfully ports legacy HdfsProperties.initBackendConfigProperties() (parity by construction with the fe-property twin) + HdfsConfigFileLoader for hadoop.config.resources XML. Re-type HdfsFileSystemProvider with bind()/create(P); create(Map)/supports() unchanged (zero regression to the hive/iceberg/broker FE filesystem + create()-side Kerberos path). Kerberos = BE-key string emission only (K1: no fe-kerberos, create()-side authenticator untouched). F1: bridge Config.hadoop_config_dir to the leaf via a system property set in FileSystemFactory.bindAllStorageProperties. Verify: fe-filesystem-hdfs 78/0 (25 new golden parity tests; existing DFSFileSystemTest 25/0 = create() path intact), checkstyle 0, RED/GREEN by mutation, fe-core -am compile clean.

+**做了什么（仅 fe-filesystem-hdfs 核心 + 3 个已白名单文件的微改/注释）**： +1. **`HdfsFileSystemProperties.java`（新）**：`implements FileSystemProperties, BackendStorageProperties`（**BE-only，不实现 HadoopStorageProperties**——catalog/Hadoop 路保持 P1-T03 后的 raw passthrough，零新行为）。`toMap()` = **忠实移植 legacy `HdfsProperties.initBackendConfigProperties()`**（XML 资源 + `hadoop./dfs./fs./juicefs.` 透传 + 恒发 `ipc.client.fallback…`/`hdfs.security.authentication` + kerberos 块 + `hadoop.username`）；`validate()` = kerberos required-check + `checkHaConfig`（inline 移植 `HdfsPropertiesUtils`）。`backendKind()=HDFS`、`type()=HDFS`、`kind()=HDFS_COMPATIBLE`。**移植源 = fe-property `HdfsProperties`（依赖轻 BE-key-only 孪生）→ parity by construction**。 +2. **`HdfsConfigFileLoader.java`（新）**：XML `hadoop.config.resources` 加载（移植 fe-property `PropertyConfigLoader`）。**F1 接线**：dir 经 `resolveHadoopConfigDir()` 读 sysprop `doris.hadoop.config.dir`（fe-core 设），默认 `$DORIS_HOME/plugins/hadoop_conf/`（与 `Config.hadoop_config_dir` 默认相同）。 +3. **`HdfsFileSystemProvider.java`（改）**：re-type 为 `FileSystemProvider` + 新增 `bind()`/`create(P)`；**`create(Map)`/`supports()` 字节不变**（hive/iceberg/broker FE filesystem 路零回归——既有 `DFSFileSystemTest` 25/0 证）。 +4. **`pom.xml`（改）**：+`fe-foundation`+`commons-lang3`（镜像 sibling s3；packaging 经 review 证无跨 loader 风险）。 +5. **F1 接线（用户选「现在接好」）**：fe-core `FileSystemFactory.bindAllStorageProperties`（**项目 P1-T02 加的方法**，+1 行 `System.setProperty("doris.hadoop.config.dir", Config.hadoop_config_dir)`）→ leaf 读 sysprop → 非默认 `hadoop_config_dir` 安装也对齐 legacy。 +6. **stale 注释修**（本改动作废）：`FileSystemPluginManager.bindAll` javadoc 去 HDFS skip-list（项目 P0-T02 加的方法）、paimon `PaimonScanPlanProvider` `KNOWN GAP 1`→标 CLOSED。 +7. **kerberos = K1**（用户 AskUserQuestion 选）：BE-key 字符串内联发射，**不建 fe-kerberos**、**不碰** fe-filesystem-hdfs 现有 create()-side `KerberosHadoopAuthenticator`。recon 证 BE model 仅需字符串、不需 fe-kerberos（真 `UGI.doAs` 留

`putAll` merge；mutation `.ifPresent→.get()`→RED）+ 2 helper（`scanContextWithStorage`/`fakeStorageWithoutBackend`）。 -5. **验证**：`PaimonScanPlanProviderTest` **52/0**、paimon 全模块

The typed OSS/COS/OBS BE map omitted AWS_CREDENTIALS_PROVIDER_TYPE, so a catalog with no static AK/SK lost the legacy ANONYMOUS hint — on IAM-role cloud hosts BE would probe instance credentials instead of going anonymous. Restore exact legacy parity by mirroring fe-core AbstractS3CompatibleProperties.doBuildS3Configuration (storage/:117-120): emit AWS_CREDENTIALS_PROVIDER_TYPE=ANONYMOUS only when both access key and secret key are blank, otherwise omit it (BE uses SimpleAWSCredentialsProvider). Inlined in each toBackendKv() — no configurable field/enum, because legacy OSS/COS/OBS never override getAwsCredentialsProviderTypeForBackend() (only S3Properties does) and fe-filesystem-{oss,cos,obs} do not depend on fe-filesystem-s3's S3CredentialsProviderType (see DV-005). BE map only; the Hadoop config map is untouched, matching legacy (key is backend-config-only). TDD: 3 new toBackendProperties_emitsAnonymousProviderTypeWhenNoStaticCredentials (RED expected but was -> GREEN) + assertNull guards on the credentialed tests. OSS 13/0, COS 12/0, OBS 12/0 + sibling tests green; checkstyle 0 violations. Docker e2e not run (P1-T06 gate).

Add one test-only assertion per module (toMaps_emit*TuningDefaultsWhenNotConfigured) covering both the BE map (AWS_MAX_CONNECTIONS / AWS_REQUEST_TIMEOUT_MS / AWS_CONNECTION_TIMEOUT_MS) and the Hadoop config map (fs.s3a.connection.maximum / .request.timeout / .timeout): S3 = 50/3000/1000, OSS/COS/OBS = 100/10000/10000 (verified against fe-core S3Properties.Env and OSS/COS/OBSProperties). Expected values are literals, not the DEFAULT_* constants, so mutating a default in the main class actually fails the guard. Mutation-proven: flipping each DEFAULT_MAX_CONNECTIONS turns all four tests red (expected <50> but was <99> / <100> but was <999>); reverted. No main code changed. S3 15/0, OSS 14/0, COS 13/0, OBS 13/0 + all sibling suites green; checkstyle 0. Docker e2e not run (P1-T06 gate).

P2-T01's HmsMetaStoreProperties needs AuthType and KerberosAuthSpec; fe-common's AuthType is off-limits to connectors (import gate) and the design homes these neutral facts in fe-kerberos (D-007). Per user decision (D-013), build fe-kerberos first. This is the dependency-free facts-carrier slice of the new top-level leaf module fe-kerberos: - AuthType (SIMPLE/KERBEROS) with fromString() resolving KERBEROS only for an explicit "kerberos" (case/space-insensitive), else SIMPLE. - KerberosAuthSpec: immutable client principal+keytab value object with hasCredentials() (both must be non-blank); the HMS service principal is intentionally excluded (it is a HiveConf override, not a doAs fact). Zero production dependencies (no Hadoop yet); the hadoop-dependent authenticator machinery is added incrementally when P2-T02 consumes it. Registered in the fe reactor right after fe-foundation. AuthTypeTest 3/0, KerberosAuthSpecTest 3/0; checkstyle 0; BUILD SUCCESS.

Depends only on fe-kerberos (D-013): the api is pure interfaces and does not use @ConnectorProperty/StorageProperties, so fe-foundation/fe-filesystem-api are deferred to the spi module where they are actually used (design 3.1 footnote updated). pom mirrors fe-connector-api (compiled into fe-core, not a deployed plugin); registered in fe-connector/pom.xml. MetaStorePropertiesContractTest 3/0 (capability defaults conservative; overridable; HMS sub-interface integrates fe-kerberos facts). checkstyle 0; connector import gate exit 0; no forbidden fe-core imports. Docker e2e not run (P2-T05 gate).

    SPI (supports(Map) self-id + first-hit ServiceLoader dispatch via MetaStoreProviders.bind) + MetaStoreParseUtils + JdbcDriverSupport.resolveDriverUrl + AbstractMetaStoreProperties + 5 providers + one META-INF/services file. Source = up-moving the paimon PaimonCatalogFactory hand-copied logic, de-fe-core-ified (HiveConf -> neutral Map, authenticator -> KerberosAuthSpec facts). fe-core legacy Paimon*MetaStoreProperties untouched. This builds the module + tests only; the paimon adapter cutover is P2-T03. Decisions (AskUserQuestion): - DV-006: fe-kerberos is a compile-dep only, ZERO new code. The HMS parser produces neutral string keys + AuthType.fromString + new KerberosAuthSpec(principal,keytab); the real UGI.doAs stays FE-side via ctx.executeAuthenticated. (Recon refuted the HANDOFF's "incrementally add the authenticator mechanism subset".) - DV-007: storage arrives as a neutral Map storageHadoopConfig (not List); the module stays hadoop/fs-free (no fe-filesystem-api dep). The parser owns the storage overlay so the kerberos-after-storage order is preserved. - D-006: no per-backend enum, no central switch. - D-4: HMS validate() restores the two legacy ParamRules (forbidIf-simple/requireIf- kerberos) the paimon hand-copy omits; CASE-SENSITIVE Objects.equals, preserving the asymmetry vs the conf-build branch's equalsIgnoreCase. Adversarial review (wf_2ddae04d-cf9, 4 lens + verify): 0 BLOCKER. Fixed MAJOR = REST token-provider equalsIgnoreCase -> "dlf".equals (paimon hand-copy latent bug; legacy ParamRules is authoritative). FS supports() -> type==null||equalsIgnoreCase (drop trim asymmetry, match legacy reject-on-malformed). Added 12 coverage tests (storage re-key, clobber-via-storage-channel, alias-first-wins, username-overlay, DLF S3-only reject, dispatch instanceof, ...). 2 honest api javadoc corrections (getDriverUrl raw, needsStorage FS). Verified: spi 41/0, checkstyle 0, import-gate exit 0, no forbidden fe-core imports, 3 mutations RED->GREEN. docker e2e NOT run (T2 gate at P2-T05).

The paimon SDK Options assembly and the filesystem/jdbc storage Configuration stay in the connector (they are not metastore-connection facts). - PaimonConnectorProvider.validateProperties: PaimonCatalogFactory.validate(props) -> MetaStoreProviders.bind(props, {}).validate(). This ADOPTS the spi's stricter, legacy-faithful rules (Q1): HMS forbidIf(simple)/requireIf(kerberos) on client principal+keytab, REST case-sensitive "dlf".equals(token.provider), and DLF requires OSS storage at CREATE CATALOG (was a build-time check). Unknown flavor now fails via bind() (no provider supports it) instead of a paimon-local message. - PaimonConnector.createCatalog: HMS/DLF branches bind the shared facts and assemble the HiveConf via the new thin PaimonCatalogFactory.assembleHiveConf(base, overrides) -- the connector seeds the external hive.conf.resources hive-site.xml as the BASE (F2), then overlays HmsMetaStoreProperties.toHiveConfOverrides() / DlfMetaStoreProperties.toDlfCatalogConf(). The build-time requireOssStorageForDlf call is removed (now enforced in validate()). - Driver-url resolution at both consumers (PaimonConnector FE registration + PaimonScanPlanProvider BE options) -> JdbcDriverSupport.resolveDriverUrl. The live JDBC driver registration (DriverManager.registerDriver + DriverShim + static caches) stays in PaimonConnector (Q2: single consumer, JVM side-effect, spi stays SDK-free). - Delete from PaimonCatalogFactory: validate / buildHmsHiveConf / buildDlfHiveConf / requireOssStorageForDlf / resolveDriverUrl / copyIfPresent / nullToEmpty / KNOWN_FLAVORS. Delete DLF_* / REST_TOKEN_PROVIDER / REST_DLF_* alias constants from PaimonConnectorProperties (the @ConnectorProperty aliases in the spi are now authoritative). HMS_URI/REST_URI/JDBC_*/flavor literals stay (buildCatalogOptions). - Tests: validate behavior moves to PaimonConnectorValidatePropertiesTest (13, incl the 3 tightenings, RED->GREEN); buildHmsHiveConf/buildDlfHiveConf/requireOssStorage content tests removed (parity now owned by the spi's Hms/DlfMetaStorePropertiesTest); add 2 assembleHiveConf tests pinning the F2 base-then-overrides layering. Verification: full paimon module 278 pass / 0 fail / 1 skip (live, gated), checkstyle 0, tools/check-connector-imports.sh exit 0.

      The class supports common parameters like access key, secret key, endpoint, and - * path style access, while also ensuring compatibility with existing S3 processing - * logic by delegating some functionality to {@code S3PropertyUtils}. - * - *

      Typical usage includes validation of required parameters, transformation to a - * backend-compatible configuration map, and conversion of URLs to storage paths. - * - *

        • - *
      • The region is typically not relevant for GCS since it is mapped internally by bucket, - * but may still be required when using the S3-compatible API.
        • - *
      • Access Key and Secret Key are not native GCS concepts. They exist here only for compatibility - * with the S3 protocol. Google recommends using OAuth2.0, Service Accounts, or other native - * authentication methods instead.
        • - *
      • Compatibility with older versions: - *
          - *
        • Previously, the endpoint was required. For example, - * {@code gs.endpoint=https://storage.googleapis.com} is valid and backward-compatible.
          • - *
        • If a custom endpoint is used (e.g., {@code https://my-custom-endpoint.com}), - * the user must explicitly declare that this is GCS storage and configure the mapping.
          • - *
        - *
        • - *
      • Additional authentication methods (e.g., OAuth2, Service Account) may be supported in the future.

Two clean-room workflow waves with zero historical priors: wave 1 = 9 finder lines over the 6 user dimensions (read/write/DDL+config/replay/cache/residual), wave 2 = 7 coverage-gap lines (show-partitions, partitions-TVF, statistics/ANALYZE, @branch, MTMV, auth/UGI, config->BE). Each finding adversarially verified. Result: 2 BLOCKER, 2 MAJOR, 16 MINOR, 10 NIT (27 confirmed / 3 partial / 3 refuted). - The 2 BLOCKERs are B8-deletion guards, not runtime bugs: legacy property/metastore/Paimon* + PaimonExternalCatalog constants are still live (cutover Kerberos wiring), and property/storage/* is shared cross-connector infra -> B8 must be phased, not a blanket delete. - The 2 MAJORs are live read-path regressions (fix with cutover): C1 minio.* catalogs unbindable (FE+BE), C2 HDFS hadoop.config.resources XML not loaded into FE catalog-create config. Wave 2 narrowed C2 (kerberos-by-alias sub-claim refuted) and independently re-derived C1. - Everything else verified at parity (replay/GSON, scan->BE contract, write rejection, cache, SHOW PARTITIONS, partitions-TVF, stats/ANALYZE, @branch, MTMV, auth/UGI). HANDOFF updated to review-complete state with the phased-B8 backlog and prioritized fix-task list.

On the SPI path `PluginDrivenSplit` forwards start/length/fileSize but never sets `selfSplitWeight`/`targetSplitSize`, so every plugin split hits the null branch → `SplitWeight.standard()` (uniform).

Legacy `PaimonSplit:60` `this.selfSplitWeight = dataFileMetas.stream().mapToLong(DataFileMeta::fileSize).sum();`. +- **Verifier:** Confirmed. BE-side thrift `self_split_weight` is only a profile-condition counter (`jni_reader.h:67`), NOT the scheduling input; both legacy and SPI set it identically only in the JNI branch → exact BE parity. The only delta is FE-side proportional-vs-uniform weighting via `FederationBackendPolicy.getSplitWeight()`. The connector already computes `selfSplitWeight` (`PaimonScanRange.getSelfSplitWeight:169`) but it never reaches `FileSplit`. +- **Remediation:** If parity matters for large-table scheduling, add `getSelfSplitWeight()`/`getTargetSplitSize()` to the SPI `ConnectorScanRange` and populate `FileSplit` fields in the `PluginDrivenSplit` ctor; otherwise document uniform-weight as accepted. + +#### R2 (scan) — EXPLAIN drops legacy `predicatesFromPaimon:` line + +- **Severity:** MINOR · **Classification:** missing-port · **Verdict:** confirmed +- **Location:** `PluginDrivenScanNode.java:270-275,315-324`; `PaimonScanPlanProvider.java:1116-1129` (appendExplainInfo).

The SPI path emits a generic `PREDICATES: ` line (raw Doris conjuncts) + `paimonNativeReadSplits=` + VERBOSE `PaimonSplitStats`, but no `predicatesFromPaimon:`. Diagnostically a silently-dropped LTZ/FLOAT/CAST conjunct is no longer observable. No correctness impact; `grep predicatesFromPaimon regression-test` = 0. +- **Evidence:** Legacy `sb.append(prefix).append("predicatesFromPaimon:"); ... for (Predicate predicate : predicates) {...}`. Connector `appendExplainInfo` emits no predicate listing. +- **Verifier:** Confirmed. The generic node retains only counts, not the converted `Predicate` objects, so it cannot trivially reconstruct the line. The only paimon EXPLAIN test (`test_paimon_predict.groovy`) asserts only on `inputSplitNum=N`, so nothing breaks. +- **Remediation:** Re-emit by re-converting the filter (byte-parity with `Predicate.toString()` not reconstructible), or accept as an intentional EXPLAIN simplification recorded in the deviations log. + +#### R3 (scan) — CAST-wrapped predicates not pushed to Paimon + +- **Severity:** MINOR · **Classification:** intentional-deviation · **Verdict:** confirmed +- **Location:** `PaimonConnectorMetadata.java:853-856` (`supportsCastPredicatePushdown=false`); legacy `PaimonPredicateConverter.java:178-200` (unwrap CastExpr).

The connector returns `supportsCastPredicatePushdown=false`, so CAST-bearing conjuncts are stripped before reaching the connector and remain BE-only (re-evaluated on returned rows). **Improves** correctness vs legacy; minor pushdown-selectivity cost. +- **Evidence:** `PaimonConnectorMetadata:854 return false;` with `'05'`/`' 5'` hazard javadoc. Sibling MaxCompute/Jdbc also return false; SPI default is true (`ConnectorPushdownOps:72-74`). Pinned by `PaimonConnectorMetadataTest:228`. +- **Verifier:** Confirmed. Strictly safer; perf-only deviation that improves correctness, not a regression. +- **Remediation:** No action for correctness; record as intentional deviation.

Legacy `PaimonScanNode.java:274`. BE `paimon_jni_reader.cpp:95`, `jni_reader.cpp:62,246-248`. +- **Description:** Legacy unconditionally calls `rangeDesc.setSelfSplitWeight(...)` on the JNI path. The connector stores the weight only when `selfSplitWeight > 0`, so a JNI split with computed weight 0 (non-DataSplit sys split with `rowCount()==0`, or DataSplit with total fileSize 0) leaves it unset → BE reads `-1` instead of 0. +- **Evidence:** `if (builder.selfSplitWeight > 0) { props.put("paimon.self_split_weight", ...); }`. +- **Verifier:** Confirmed; reachable. Impact is profile-only: `_self_split_weight` feeds only the `_max_time_split_weight_counter` diagnostic; never affects rows/counts/predicates/schema. (Finding's evidence has a minor BE line-citation mix-up; both underlying facts hold.) +- **Remediation:** No functional fix required; drop the `> 0` gate if exact profile parity is wanted. + +#### R2 (be) — `history_schema_info` emitted as scan-level dict, not per-split-accumulated + +- **Severity:** NIT · **Classification:** intentional-deviation · **Verdict:** confirmed +- **Location:** `PaimonScanPlanProvider.java:1214-1232` (`buildSchemaEvolutionParam`, call site `:651`). Legacy `PaimonScanNode.java:236-251`. BE `table_schema_change_helper.h:240-266`. +- **Description:** Legacy added history entries lazily, one per distinct file `schema_id` referenced by a split, plus the `-1` entry. The connector emits, once at scan-node level, the `-1` entry **plus** an entry for every committed schema id (`SchemaManager.listAllIds()`). BE needs only the `-1` entry + an entry per split's `schema_id`; `listAllIds()` is a superset, so the "miss table/file schema info" error cannot fire spuriously. +- **Evidence:** `for (Long schemaId : schemaManager.listAllIds()) { history.add(buildSchemaInfo(schemaId, ...)); }`. +- **Verifier:** Confirmed. Paimon schema files are retained (not GC'd like snapshots), so the eager set is always a superset → equivalence holds; only metadata-read cost differs (reads all historical schemas even for single-schema queries). Both sides correctly skip non-data sys tables. +- **Remediation:** Accept as intentional; narrow to planned-split schema_ids only if cost matters on heavily-evolved tables. + +--- + +## Write (INSERT / sink) + +Covered by the **write** finder line. + +### What was reviewed / verified-OK + +Determined that **neither** legacy nor current paimon has a data-write (INSERT / sink / commit) path; the net end-to-end behavior is "INSERT rejected" in both — no data-write regression. Legacy `PaimonMetadataOps` has zero write/commit/`TableWrite` usage and `PaimonExternalCatalog extends ExternalCatalog` directly, so a legacy INSERT hit the catch-all `throw "Load data ... not supported"`. The current `PaimonConnector` declares no write capability (`getCapabilities` = MVCC_SNAPSHOT / TIME_TRAVEL / PARTITION_STATS only; comment "paimon write is not migrated") and does not override `getWritePlanProvider()` (default null); `PaimonConnectorMetadata` overrides zero `ConnectorWriteOps` methods, so `supportsInsert()`/`supportsInsertOverwrite()` default false and `beginInsert`/`getWriteConfig` throw. Every write entry point in the bridge fails loud: plain INSERT at `PhysicalPlanTranslator` (writePlanProvider==null + supportsInsert()==false → AnalysisException), INSERT OVERWRITE at `InsertOverwriteTableCommand.allowInsertOverwrite`, CTAS at the insert stage; redundant guard at `PluginDrivenInsertExecutor.beforeExec:116`.

Both legacy and current reject INSERT/INSERT OVERWRITE/CTAS-as-write loudly. +- **Verifier:** Confirmed. Minor framing nit: on the SPI branch paimon is a `PluginDrivenExternalCatalog`, so the legacy `UnboundTableSinkCreator` throw is bypassed and rejection is downstream at the translator (which the finding also cites).

(type: paimon) does not support INSERT operations")`). User-visible outcome unchanged; only stage/wording differ. Backup guard at `PluginDrivenInsertExecutor:116`. +- **Verifier:** Confirmed. The finding's primary citation (`:65/:68`) is the no-DML overload; a real INSERT uses the DML overloads, which behave identically — strengthens the finding. +- **Remediation:** None; message is arguably clearer than legacy. + +--- + +## DDL (catalog / db / table / CTAS) and config + +Covered by three finder lines: **ddl-catalog** (CREATE/DROP CATALOG & DATABASE), **ddl-table** (CREATE/DROP TABLE, CTAS, type mapping), and **config** (storage credentials + metastore connection assembly). + +### What was reviewed / verified-OK + +**Catalog/DB dispatch.** `CatalogFactory.createCatalog` routes `paimon` through `SPI_READY_TYPES` → `PluginDrivenExternalCatalog`; metastore flavor resolved from `paimon.catalog.type` (default `filesystem`, lowercased) byte-equivalently to legacy. Unknown flavor rejected at CREATE CATALOG (`MetaStoreProviders.bind` → `IllegalArgumentException` → `DdlException`), functionally equivalent to legacy. **CREATE/DROP DATABASE are dispatched** (the legacy no-op bug class is closed): `PluginDrivenExternalCatalog` overrides `createDb`/`dropDb`/`createTable`/`dropTable` despite `metadataOps==null`, reaching the connector. HMS-only create-db-with-props gate, force-cascade drop, and exception wrapping mirror legacy (pinned by `PaimonConnectorMetadataDbDdlTest`, 10 tests). + +**CREATE/DROP TABLE + type mapping.** Doris→Paimon scalar mapping (`PaimonTypeMapping` vs `DorisToPaimonTypeVisitor`) verified byte/behavior-equivalent (CHAR/VARCHAR/STRING→VarChar(MAX), DATETIME→plain TimestampType, DECIMAL families, VARBINARY/VARIANT, unsupported throws in both). Nested-type nullability non-divergent (every Doris nested type is nullable by default; map key forced `.copy(false)` identically). Paimon→Doris read-back, property normalization (strip PK+comment, location→`CoreOptions.PATH`), primary/partition keys, IF NOT EXISTS double-create probing (remote + local two-arm) all at parity.

Filed as "ERR_DB_CREATE_EXISTS (1007) vs generic DdlException". +- **Verifier (partial — corrected):** Mechanism real and grade right, but the **error-code premise is inaccurate**: legacy `performCreateDb` does call `ERR_DB_CREATE_EXISTS`, but that throw happens inside `createDbImpl`'s own `catch(Exception)` which re-wraps via `DdlException(String, Throwable)` — which does **not** set the MySQL code. So legacy also loses code 1007 before the client sees it. The only real divergence is **message-string** wording, not an error code. +- **Remediation:** Acceptable as-is; surface a dedicated message only if client tooling depends on the exact text. + +#### R2 (catalog) — Legacy paimon table-cache CacheSpec validations not ported + +- **Severity:** MINOR · **Classification:** missing-port · **Verdict:** confirmed +- **Location:** legacy `PaimonExternalCatalog.java:161-170` vs current `PluginDrivenExternalCatalog.java:162-173`. +- **Description:** Legacy validated `meta.cache.paimon.table.{enable,ttl-second,capacity}` at CREATE CATALOG via `CacheSpec.check*` (throws `DdlException` for malformed values). The plugin path's `checkProperties` does not re-run these; a malformed value (`capacity=-5`, `ttl-second=abc`) that legacy rejected is now accepted. +- **Verifier:** Confirmed. Blast radius correctly bounded — these keys are **dead on the plugin path** (`PaimonExternalMetaCache`/`ExternalMetaCacheMgr.paimon` have zero non-legacy callers; plugin path uses the generic schema cache), so even well-formed values are no-ops. No query-correctness impact. +- **Remediation:** Prefer warn-and-strip at create (keys are confirmed dead); restoring full validation would re-impose checks on knobs that no longer do anything. + +#### R3 (catalog) — `listDatabaseNames` swallows remote failures → empty + +- **Severity:** MINOR · **Classification:** intentional-deviation · **Verdict:** confirmed +- **Location:** `PaimonConnectorMetadata.java:95-104` vs legacy `PaimonMetadataOps.java:336-342`. +- **Description:** Legacy rethrew a metastore enumeration failure as `RuntimeException`; current catches `Exception`, `LOG.warn`s (no catalog name), returns `emptyList()`. A transient remote failure now presents as "zero databases" (empty SHOW DATABASES) rather than an error. Reaches the user via `PluginDrivenExternalCatalog.listDatabaseNames` → DB-init. +- **Verifier:** Confirmed. **Caveat:** the finding's mitigating claim of a "shared best-effort convention" is factually wrong — Hive/Hudi/JDBC/MaxCompute/Trino all propagate; Iceberg's emptyList is only for a structural unsupported-namespaces case. Paimon is the **sole** connector swallowing a generic remote failure. Low impact (diagnosability/UX only). +- **Remediation:** Keep best-effort if intended but include catalog name in the `LOG.warn` (legacy message did); or distinguish empty-catalog from remote-error and rethrow the latter. + +#### R1 (table) — CREATE TABLE remote-only existing table loses MySQL errno 1050 + +- **Severity:** MINOR · **Classification:** regression · **Verdict:** confirmed +- **Location:** `PluginDrivenExternalCatalog.java:298-321`; `PaimonConnectorMetadata.java:725-739`. Legacy `PaimonMetadataOps.java:189-197`. +- **Description:** Legacy reported `ERR_TABLE_EXISTS_ERROR` (1050 / 42S01) when the table existed remotely and no IF NOT EXISTS. The bridge raises 1050 only for the **local-cache-conflict** arm (`:310-313`); a table existing **only remotely** falls through to `createTable(ignoreIfExists=false)` → `TableAlreadyExistException` → generic `DdlException`. CREATE still fails; only the error code/SQLSTATE/message changed. +- **Evidence:** `if (localExists) { ErrorReport.reportDdlException(ERR_TABLE_EXISTS_ERROR, ...); }` — local arm only; bridge comment self-documents the gap. +- **Verifier:** Confirmed. errno 1050 is a documented MySQL contract some ORMs branch on, so MINOR (not NIT). Reachability narrow (table exists remotely but absent from this FE cache — stale cache / other-FE / external create). The bridge already computes `remoteExists`. +- **Remediation:** Mirror the local arm: `if (remoteExists && !ifNotExists) reportDdlException(ERR_TABLE_EXISTS_ERROR, ...)` before falling through. + +#### R3 (table) — Auto/expression partition rejected where legacy silently stripped + +- **Severity:** MINOR · **Classification:** intentional-deviation · **Verdict:** confirmed +- **Location:** `PaimonSchemaBuilder.java:122-139`; `CreateTableInfoToConnectorRequestConverter.java:125-191`. Legacy `PaimonMetadataOps.java:244` + `PartitionDesc.java:105-157`. +- **Description:** For an expression/auto partition (e.g. `PARTITION BY RANGE(date_trunc(col,...))`) legacy returned the bare underlying column names and silently dropped the transform, creating a table partitioned by the bare column. The converter emits a TRANSFORM field and the connector throws `DorisConnectorException("Paimon only supports identity partition columns, got transform: ...")`. Deliberate, safer deviation (mirrors MaxCompute `identityPartitionColumns`); changes behavior only for the auto-partition edge case (error vs silent partition-by-column). +- **Verifier:** Confirmed full chain (UnboundFunction → `transform=date_trunc` → guard → `DdlException`). Identity and LIST partitions unaffected. +- **Remediation:** Keep the explicit rejection; document as intentional deviation in HANDOFF. + +#### C1 (config) — MinIO storage backend unbindable + +- **Severity:** MAJOR (downgraded from BLOCKER) · **Classification:** regression · **Verdict:** partial +- **Location:** `S3FileSystemProvider.java:45-73` (supports/aliases); `FileSystemFactory.java:131-141` (no-match → empty list, no throw). +- **Description:** Legacy `MinioProperties` recognized `minio.endpoint/access_key/secret_key/region/session_token/connection.*/use_path_style` (region default `us-east-1`) and produced S3A config. The new path sources storage exclusively from fe-filesystem, which has **no MinIO provider** (registered: local/oss/azure/broker/s3/hdfs/cos/obs); `S3FileSystemProvider.supports()` and `S3FileSystemProperties` aliases include no `minio.*` key. A pure `minio.*` CREATE CATALOG matches no provider → `bindAllStorageProperties` returns empty (no throw) → empty hadoop map → no `fs.s3.impl` → paimon read fails "no file io for scheme s3". +- **Verifier (partial — corrected to MAJOR):** Mechanism and regression confirmed; no `minio.*→s3.*` normalization exists anywhere (grep ZERO). **But BLOCKER overstates impact:** every paimon MinIO regression suite (`test_paimon_table_properties.groovy` etc.) configures MinIO via canonical `s3.endpoint/s3.access_key/s3.secret_key`, which **do** match `S3FileSystemProvider` and work end-to-end. The default/tested MinIO path is unaffected; only the legacy `minio.*`-aliased namespace is broken, with a trivial `s3.*` workaround and zero test coverage demonstrating reliance. +- **Per-key loss (pure `minio.*` only):** endpoint, region(us-east-1), access_key, secret_key, session_token, connection.maximum(100), connection.request.timeout(10000), connection.timeout(10000), use_path_style(false), force_parsing_by_standard_uri. (Mixed configs using generic `s3.*`/`endpoint`/`region` aliases still bind.) +- **Remediation:** Add `minio.*` aliases to `S3FileSystemProperties` endpoint/region/access_key/secret_key/session_token/connection.*/use_path_style and to `S3FileSystemProvider.supports()` (region default `us-east-1`); or add a dedicated MinIO fe-filesystem provider. + +#### C2 (config) — HDFS catalog-create drops legacy-derived config keys + +- **Severity:** MAJOR · **Classification:** missing-port · **Verdict:** confirmed +- **Location:** `PaimonConnector.java:222-228` (`buildStorageHadoopConfig`) + `PaimonCatalogFactory.java:287-297` (raw passthrough, `:294`); `HdfsFileSystemProperties.java` (does not implement `HadoopStorageProperties`). +- **Description:** Legacy built the HDFS Configuration from `HdfsProperties.getHadoopStorageConfig()` emitting: (1) keys loaded from `hadoop.config.resources` XML; (2) `ipc.client.fallback-to-simple-auth-allowed` default `true`; (3) `hdfs.security.authentication=`; (4) kerberos `hadoop.*` derived from canonical `hdfs.authentication.{type,kerberos.principal,kerberos.keytab}` aliases; (5) `juicefs.*`. The new catalog-create path builds the Configuration only from `applyStorageConfig`'s raw passthrough of `fs.`/`dfs.`/`hadoop.` keys, so all five are dropped — HA HDFS via xml cannot resolve its nameservice; a catalog using `hdfs.authentication.*` aliases never gets `hadoop.security.authentication=kerberos`. +- **Verifier:** Confirmed. **Scope clarification (does not change severity):** the gap is strictly the **FE-side catalog-create** Configuration; the **BE/scan path is NOT affected** — `PaimonScanPlanProvider.java:620` consumes `sp.toBackendProperties().toMap()`, which for HDFS returns the full backend map (XML, ipc default, hdfs.security.authentication, kerberos-from-alias, juicefs). Kerberos UGI login is FE-injected via `executeAuthenticated`. Genuine connectivity break for HA-HDFS-via-xml + FILESYSTEM/JDBC flavors, gated and with raw-`hadoop.*` workarounds → MAJOR not BLOCKER. No test covers the gap (`PaimonCatalogFactoryTest:218-238` only asserts the reduced raw passthrough). +- **Remediation:** Have `buildStorageHadoopConfig`/`buildHadoopConfiguration` also fold in `sp.toBackendProperties().toMap()` for HDFS (reuses the already-ported map), or implement `HadoopStorageProperties` on `HdfsFileSystemProperties`. Verify a Kerberized HA HDFS paimon catalog with `hdfs.authentication.*` aliases + `hadoop.config.resources` can connect via the plugin path. + +#### C4 (config) — HMS socket timeout hardcoded 10s + +- **Severity:** MINOR · **Classification:** missing-port · **Verdict:** confirmed +- **Location:** `HmsMetaStorePropertiesImpl.java:179-181`. Legacy `HMSBaseProperties.java:204-208`. +- **Description:** Legacy set the metastore client socket timeout from `Config.hive_metastore_client_timeout_second` when the user had not overridden `hive.metastore.client.socket.timeout`; the connector hardcodes literal `"10"` (the current default). A user-set per-catalog property suppresses the default in both. The only divergence: an operator who raises `fe.conf hive_metastore_client_timeout_second` (e.g. 60) without the per-catalog property gets 60 in legacy but 10 here. +- **Verifier:** Confirmed (guard-key equivalence checked by disassembly). The FE Config value is genuinely unreachable from the connector — `ConnectorContext.getEnvironment()` exposes only doris_home and jdbc_drivers_dir, and metastore-spi has no fe-common dependency. Introduced by the SPI move. Opt-in-tuning-only; default preserved. +- **Remediation:** Thread the FE config value through `ConnectorContext.getEnvironment()` (or a dedicated accessor) instead of literal `"10"`. Low urgency. + +--- + +## Metadata replay (persist / restart / GSON) + +Covered by the **replay** finder line. **No findings** (zero defects in this dimension). + +### What was reviewed / verified-OK + +Persisted-state parity and replay-rebuild were traced clean-room: the bridge persisted objects (`PluginDrivenExternalCatalog/Database/Table`, `PluginDrivenMvccExternalTable`) and runtime carriers (`PluginDrivenMvccSnapshot`, `PluginDrivenSchemaCacheValue`), GSON `RuntimeTypeAdapterFactory` registrations, and base `ExternalCatalog` field/transient layout, against legacy paimon classes + legacy GSON registrations. Verified: + +1. **Persisted shape identical** — both legacy paimon classes and current PluginDriven classes add zero `@SerializedName` fields; both persist only the base hierarchy + `catalogProperty` (which carries `type` and `paimon.catalog.type`). No field added/dropped. +2. **All three GSON subtype registrations present and consistent** — Catalog: PluginDriven default + `registerCompatibleSubtype` for all 5 legacy flavor class names. Database: `PaimonExternalDatabase` → `PluginDrivenExternalDatabase`. Table: `PaimonExternalTable` → `PluginDrivenMvccExternalTable` (correctly the MVCC variant). No missing registration → no replay ClassCastException. +3. **Flavor preserved on replay** — both derive flavor solely from `paimon.catalog.type`; collapsing 5 class names onto one PluginDriven catalog loses no flavor info (the legacy `*HMS/*DLF/*File/*Rest` subclasses were `@Deprecated` pass-throughs). +4. **Transient re-init complete** — post-deserialization `connector==null`; `initLocalObjects()` gated on non-persisted `objectCreated` rebuilds connector + transactionManager + executionAuthenticator from `catalogProperty`. +5. **type/logType migration** — `CatalogFactory` force-persists `type=paimon`; `gsonPostProcess` backfills type from logType and migrates `logType PAIMON→PLUGIN`. +6. **MVCC snapshot not persisted** — both snapshots are per-query runtime objects, never GSON-registered. + +**Overall:** persistence + replay + GSON serde at parity; no regressions, missing ports, or standalone defects. + +--- + +## Metadata cache (schema / partition / sys-table / mvcc) + +Covered by the **cache** finder line. + +### What was reviewed / verified-OK + +Reviewed the connector (`PaimonConnectorMetadata`, `PaimonTableResolver`, `PaimonCatalogOps`) and the bridges (`PluginDrivenExternalTable`, `PluginDrivenMvccExternalTable`, `PluginDrivenMvccSnapshot`, `PluginDrivenSysExternalTable`, `ExternalMetaCacheInvalidator`) against the legacy paimon cache stack, tracing the actual fill/hit/invalidate/refresh wiring. The architecture deliberately replaces legacy's two engine-specific caches with (a) a single name-keyed latest-schema entry in the generic `DefaultExternalMetaCache`, and (b) **no second-level partition/snapshot cache** — partition view + snapshot pin + schema-at-snapshot are listed once per query and held on the per-statement `PluginDrivenMvccSnapshot` (the CACHE-P1 design). + +Verified at parity: single-pin MVCC consistency within one query; no two-snapshot key collision (time-travel schemas never enter the shared cache); REFRESH TABLE reaches the cache (`forTableIdentity` invalidation → fresh `getTableHandle+getTableSchema`); REFRESH CATALOG nulls+rebuilds the connector; sys-table schema resolution via `getSchemaCacheValue` override (closes the legacy missing-override bug class); no hidden stale Table cache in the connector; partition staleness `Partition.lastFileCreationTime()` → `MTMVTimestampSnapshot`; `isPartitionInvalid` + `getNewestUpdateVersionOrTime` bypass-pin semantics. **No BLOCKER/MAJOR**; deviations are intentional (CACHE-P1) and TTL/REFRESH-bounded with the same effective staleness profile as legacy. + +### Findings + +| id | title | severity | legacy-class | verdict | +|----|-------|----------|--------------|---------| +| MC1 | Latest schema cached name-only (no schemaId in key) | MINOR | intentional-deviation | confirmed | +| MC2 | Time-travel schema re-resolved per query (no second-level cache) | NIT | intentional-deviation | confirmed | + +#### MC1 — Latest schema cached name-only + +- **Severity:** MINOR · **Classification:** intentional-deviation · **Verdict:** confirmed +- **Location:** `ExternalTable.java:423-426`; `ExternalMetaCacheMgr.java:425-433`. Legacy `PaimonExternalMetaCache.java:73-75` + `PaimonSchemaCacheKey.java`. +- **Description:** Legacy keyed the schema cache by `(NameMapping, schemaId)` and derived the latest schemaId from the latest-snapshot projection. The new model keys by NameMapping only and reads `table.rowType()` of a freshly-resolved handle on each miss. Both TTL-bound and need REFRESH for immediate consistency; no concrete wrong-result scenario. Flagged only because the keying mechanism differs. +- **Verifier:** Confirmed. Time-travel schema IS pinned separately (`loadSnapshot` stores `pinnedSchema`), so two snapshots do not collide on the name-only key. Under async snapshot-cache refresh, legacy could surface an evolved latest schema marginally earlier; new model waits on the schema entry's own TTL/REFRESH — "different staleness shape, no substantiated regression." +- **Remediation:** Optional one-line doc note on `PluginDrivenExternalTable.initSchema()`; no code change. + +#### MC2 — Time-travel schema re-resolved per query + +- **Severity:** NIT · **Classification:** intentional-deviation · **Verdict:** confirmed +- **Location:** `PluginDrivenMvccExternalTable.java:259-271`. Legacy `PaimonExternalTable.java:338-371` + schemaEntry. +- **Description:** Legacy served a FOR VERSION/TIME AS OF schema from the shared `(NameMapping, schemaId)` cache (repeated time-travel hit cache). The new model resolves schema-at-snapshot fresh inside `loadSnapshot` every query and pins it for that statement only — one extra `schemaAt` round-trip per time-travel query, within the CACHE-P1 design. Latest reads still cached via super; correctness preserved. +- **Verifier:** Confirmed; scoped to time-travel only. Pure perf trade. +- **Remediation:** None; a connector-side schemaId-keyed memo could be reintroduced later without touching the bridge if measured overhead warrants. + +--- + +## Residual old logic / fallback (B8 scoping) + +Covered by the **residual** finder line. + +### What was reviewed / verified-OK + +Swept the connector module (18 main classes) and the generic bridge for residual legacy logic, fallbacks, source-name branches, and dead-vs-live status. Verified clean: `tools/check-connector-imports.sh` exits 0 (connector does **not** illegally import fe-core; only doc-comment legacy-parity notes). All connector `instanceof` are legitimate Paimon-SDK/SPI dispatch. Connector `"paimon"` literals are its own identity registration. No force_jni/legacy fallback to fe-core. Generic bridge `getEngine()` switch is connector-agnostic TableType-identity preservation. Cut-over paimon never hits the legacy `instanceof Paimon*`/`Type.PAIMON` branches in Env SHOW-CREATE / `buildDbForInit` / ShowPartitions / UserAuthentication / RouteResolver — all take the PluginDriven branch; the legacy branches are DEAD-but-harmless. + +### Findings + +| id | title | severity | legacy-class | verdict | +|----|-------|----------|--------------|---------| +| R1 | LIVE path depends on legacy `property/metastore/Paimon*` + `PaimonExternalCatalog` constants | BLOCKER | n/a | confirmed | +| R2 | `property/storage/{S3,OSS,COS,OBS,Minio}Properties` shared cross-connector infra | BLOCKER | n/a | confirmed | +| R3 | Generic bridge source-name-branches VERBOSE per-backend EXPLAIN to paimon only; MaxCompute loses `backends:` block | MINOR | regression | partial | +| R4 | Dead legacy paimon handler/imports in `ShowPartitionsCommand` | MINOR | intentional-deviation | confirmed | +| R5 | Dead legacy paimon branches in Env / ExternalCatalog / UserAuthentication / RouteResolver | MINOR | intentional-deviation | confirmed | +| R6 | `systable/PaimonSysTable` + `metacache/paimon/*` + `ExternalMetaCacheMgr.paimon()` dead-for-cutover but compile-referenced | MINOR | intentional-deviation | confirmed | + +#### R1 — LIVE path depends on legacy metastore-props (NOT deletable) + +- **Severity:** BLOCKER · **Classification:** n/a · **Verdict:** confirmed +- **Location:** `PluginDrivenExternalCatalog.java:121/130/136-137`; `MetastoreProperties.java:90`; `PaimonPropertiesFactory.java:28-32`; `AbstractPaimonProperties.java:73-84`; `PaimonFileSystemMetaStoreProperties.java:21,82`. +- **Description:** The cut-over `initPreExecutionAuthenticator()` calls `catalogProperty.getMetastoreProperties()` → `MetastoreProperties.create()` → `PaimonPropertiesFactory` which instantiates the legacy `Paimon{FileSystem,HMS,AliyunDLF,Jdbc,Rest}MetaStoreProperties`. `AbstractPaimonProperties.initHdfsExecutionAuthenticator` wires the HDFS Kerberos `HadoopExecutionAuthenticator` — load-bearing for kerberized filesystem/jdbc paimon. These classes also import `datasource/paimon/PaimonExternalCatalog` constants (`PAIMON_FILESYSTEM`/`PAIMON_HMS`). +- **Verifier:** Confirmed. Live runtime + compile dependency both real; deleting `PaimonExternalCatalog` breaks compilation of 5 live metastore-props classes; deleting the metastore-props breaks Kerberos wiring for cutover paimon. Connector import check rc=0 (this is engine-bridge→fe-core-legacy, not a connector violation). HANDOFF.md:36-42 lists exactly these as B8 targets. +- **Remediation:** Before B8: KEEP `property/metastore/Paimon*MetaStoreProperties` + `PaimonPropertiesFactory` + `AbstractPaimonProperties`; migrate the `PAIMON_FILESYSTEM`/etc. constants out of `datasource/paimon/PaimonExternalCatalog` into the metastore-props module **before** deleting `PaimonExternalCatalog`.

Deleting them is a whole-engine break. +- **Verifier:** Confirmed. The paimon connector AND even the legacy fe-core paimon tree reference none of these 5 classes. Concrete consumers verified: `DLFCatalog.java:22`, `StoragePolicy.java:20`, `S3StorageVault.java:24`, `BrokerLoadJob.java:29`, `S3ConnectivityTester.java:23`, `IcebergRestProperties.java:48`. Count nuance: finding said 83 (broad `property.storage.*` grep = 122 files repo-wide); the 5 named classes have ~26 named main-source consumers. Either metric → shared infra. +- **Remediation:** Explicitly EXCLUDE `property/storage/*` from the B8 paimon-deletion set; only the connector's own in-module storage was replaced. + +#### R3 — Generic bridge source-name-branches VERBOSE EXPLAIN to paimon only + +- **Severity:** MINOR (downgraded from MAJOR) · **Classification:** regression · **Verdict:** partial +- **Location:** `PluginDrivenScanNode.java:305-308`; baseline `FileScanNode.java:151-152,253-256`. +- **Description:** `FileScanNode` emits `appendBackendScanRangeDetail()` (the `backends:` block + per-file paths + dataFileNum/deleteFileNum/deleteSplitNum) **unconditionally** for `VERBOSE && !isBatchMode()`. `PluginDrivenScanNode` overrides without calling super and re-emits that block **only when `"paimon".equals(catalog.getType())`**. Legacy `MaxComputeScanNode` (extends `FileQueryScanNode`, no override) DID show the block; after cutover, cut-over MaxCompute VERBOSE EXPLAIN loses it. Direct violation of the project rule that `PluginDrivenScanNode` must not branch on source name for universal `FileScanNode` behavior; the inline comment claiming MaxCompute output stays byte-unchanged is wrong. +- **Verifier (partial — corrected to MINOR):** All facts verified (git baseline + routing). Real regression but **EXPLAIN-VERBOSE diagnostic-only** (no query/data impact) and **no regression test asserts `backends:` for maxcompute** → MAJOR overstates user impact; MINOR is right. **Note: this is in the GENERIC bridge and affects MaxCompute, not a paimon-only concern.** +- **Remediation:** Emit `appendBackendScanRangeDetail()` unconditionally under `VERBOSE && !isBatchMode()` (matching `FileScanNode`); connectors without delete files naturally render deleteFileNum=0 via `getDeleteFiles→empty`.

Harmless at runtime but blocks deleting the 3 legacy classes (compile dependency). +- **Verifier:** Confirmed. The only `new PaimonExternalCatalog` is in `PaimonExternalCatalogFactory:42` which has **zero callers**; GSON `registerCompatibleSubtype` (`:402-411`) remaps persisted legacy names to `PluginDrivenExternalCatalog` on deserialization — closing the replay path. `handleShowPluginDrivenTablePartitions` reproduces the same 5-column rich result (D-045).

The 2026-06-14 applyCanonicalMinioConfig work targeted the obsolete applyStorageConfig path and was never carried into this branch. Legacy MinioProperties is just "S3 with a custom endpoint": pure inherited S3A config, only the minio.* prefix, region default us-east-1, and tuning defaults 100/10000/10000 differ from S3. Solution (shared fe-filesystem-s3, no dedicated provider): - S3FileSystemProperties: append minio.* aliases at the END of each field's names() (endpoint/region/access_key/secret_key/session_token/ connection.maximum/connection.request.timeout/connection.timeout/ use_path_style). First-alias-wins keeps canonical s3.*/AWS_* outranking, so the s3.* path is byte-for-byte unchanged. - S3FileSystemProvider: add minio.access_key/endpoint/region to the detection arrays so a pure minio.* map satisfies supports(). - Preserve legacy MinIO tuning defaults (100/10000/10000) via a gated applyLegacyMinioTuningDefaults() in the post-bind normalize hook: applied only when a minio.* raw key is present and the knob is unset under any alias (raw-key presence, not value-equals-default, so explicit values win); s3.* path untouched. Region us-east-1 already preserved by the endpoint-only normalize branch. Tests (fe-filesystem-s3, 28/0/0): provider supports() for pure minio map; properties bind all aliases + honor explicit tuning; endpoint-only region default + FE fs.s3.impl/fs.s3a.* + BE AWS_*; tuning-default preservation (100/10000/10000); s3-outranks-minio precedence guard.

MinIO is +literally "S3 with a custom endpoint." The only deltas are (a) the alias key prefix and (b) three +tuning defaults + the region default. Precedent: `CosFileSystemProvider`/`CosFileSystemProperties` +is a *dedicated* provider only because COS emits genuinely COS-specific Hadoop keys +(`fs.cosn.*`, `fs.cos.impl`) and uses a Tencent native SDK in `CosObjStorage`. MinIO emits **none** — +a dedicated provider would be a near-empty clone of S3, pure duplication for no behavioral gain. + +**The one caveat — differing tuning defaults — and why it does not block aliasing.** +`ConnectorProperty` defaults are *field-level*, applied whenever no alias for that field is present +in the raw map (`ConnectorPropertiesUtils.bindConnectorProperties` only `field.set`s when a name +matched). They cannot be conditionalized on *which* alias matched. So I cannot make +`maxConnections` default to `50` for an `s3.*` catalog and `100` for a `minio.*` catalog purely by +adding aliases. Resolution: **add `minio.*` as aliases on the existing tuning fields and accept the +S3 defaults (50/3000/1000) for a `minio.*` catalog that omits the tuning keys.** Justification: + +- The tuning values are connection-pool/timeout knobs; both sets are functional against MinIO. The + legacy MinIO values (100/10000/10000) were never documented as required for correctness — they are + a historical default, not a contract. +- A `minio.*` catalog that *explicitly* sets `minio.connection.maximum` etc. is honored exactly + (the alias binds the value). Only the *unset* case differs, and only in pool size / timeouts. +- Conditionalizing the default would require post-bind logic ("if a `minio.*` alias matched and the + tuning key was absent, override to 100/10000/10000") — added complexity in shared code, touching + the s3 hot path, to preserve a non-contractual default. Not worth the blast-radius risk. + +This is the single intentional, documented behavioral deviation from legacy MinIO. It is called out +in Risk Analysis and Open Questions for the main agent to ratify. **Region default `us-east-1` IS +preserved** — `S3FileSystemProperties.normalizeForLegacyS3Compatibility()` already derives +`region = DEFAULT_REGION ("us-east-1")` when an endpoint is set but region is blank +(`S3FileSystemProperties.java:360-362`), exactly matching legacy MinIO's `region="us-east-1"` +default behavior for the common endpoint-only case. (Field-level default of legacy is `us-east-1` +unconditionally; the SPI achieves the same effective value for endpoint-only configs and for +region-only/AWS-endpoint configs derives the real region — strictly better.) + +## Ordering invariant (load-bearing for s3.* byte-parity) + +`ConnectorPropertiesUtils.getMatchedPropertyName` (`ConnectorPropertiesUtils.java:96-108`) returns +the **first** name in the annotation's `names()` array that is present in the map. Therefore **all +`minio.*` aliases MUST be appended at the END of each field's existing `names()` list.** With +`minio.*` last, an `s3.*`-keyed (or `AWS_*`-keyed) catalog binds exactly as today even if it also +happened to carry a `minio.*` key — `s3.endpoint` outranks `minio.endpoint`.

A paimon catalog whose HDFS HA topology lives only in a `hadoop.config.resources` XML file could not resolve its nameservice on the SPI plugin path (filesystem/jdbc): the FE catalog-create Configuration copied the `hadoop.config.resources` key verbatim but never loaded the XML contents, so `hdfs://ns1/...` failed to resolve `ns1`. (BE/scan path was unaffected.) Root cause: `HdfsFileSystemProperties` did not implement `HadoopStorageProperties`, so `toHadoopProperties()` was empty and HDFS contributed nothing to the connector's `buildStorageHadoopConfig()` -> FE Configuration. The XML keys (already parsed into `backendConfigProperties` at bind time for the BE path) never reached the FE config. Solution: `HdfsFileSystemProperties implements HadoopStorageProperties`. `toHadoopConfigurationMap()` returns a DEFAULTS-FREE map (XML + HA + auth keys, via `new Configuration(false)`), while `toMap()` (BE) keeps the defaults-laden map for byte-parity with legacy `getBackendConfigProperties()`. Defaults-free because a naive full `backendConfigProperties` carries 62 `fs.s3a.*` Hadoop defaults that, in a multi-backend catalog (object store + HDFS-with-XML), would clobber a co-bound S3/MinIO provider's tuned `fs.s3a.path.style.access=true` (a regression vs the current branch; found by the design red-team, empirically verified on hadoop 3.4.2). Parity for filesystem/jdbc/hms; DLF deviation accepted (DV-036). Also corrected 4 stale comments asserting the now-false "HDFS contributes nothing to storageHadoopConfig". Tests: flipped the bug-encoding `classifiersMatchHdfs` assertion; added `xmlKeysReachHadoopConfigMap` (C2 regression pin), `hadoopConfigMapExcludesFramework DefaultsButBeMapKeepsThem` (clobber guard + FE/BE asymmetry), `hadoopConfigMapKeepsMeaningfulKeys`, and a connector end-to-end glue test `buildStorageHadoopConfigFoldsInHdfsHadoopMap`. fe-filesystem-hdfs 28/0, paimon 279/0/1-skip, checkstyle + connector-import-check clean; docker e2e gated/not-run.

The parent FileScanNode emits it unconditionally under `VERBOSE && !isBatchMode()`. The source-name gate (FIX-PAIMON-EXPLAIN-GAP d4526013364) (1) regressed cut-over MaxCompute / TrinoConnector VERBOSE EXPLAIN — both legacy nodes extended FileQueryScanNode and inherited the unconditional block; (2) violated the project rule that the generic node must not branch on a connector source name; (3) carried a false comment claiming es/jdbc/max_compute output stayed byte-unchanged. Solution: remove the `&& "paimon".equals(...getType())` conjunct so the gate is `VERBOSE && !isBatchMode()`, identical to the parent FileScanNode; rewrite the inline comment. paimonNativeReadSplits stays behind the SPI ConnectorScanPlanProvider.appendExplainInfo delegation (unchanged). Scope (design red-team wf_3518653b-3cb corrected, broader than the review's "maxcompute" framing): SPI_READY_TYPES = {jdbc, es, trino-connector, max_compute, paimon} all route through this node. paimon unchanged; maxcompute/trino-connector parity-RESTORED; es/jdbc gain new, NPE-safe, rule-mandated VERBOSE output (same category as the sibling partition=N/M and pushdown agg= lines already emitted unconditionally for them). NPE-safe because PluginDrivenScanNode produces only PluginDrivenSplit (extends FileSplit) -> always a FileScanRange, and getDeleteFiles is null-guarded; es/jdbc render synthetic per-split paths (es://idx/shard, jdbc://virtual). Diagnostic-only (VERBOSE EXPLAIN text); no query/data impact; no regression test pins these connectors' VERBOSE EXPLAIN text. The sibling "es_http" `ES terminate_after:` gate is left as a separate residual (R3-LAYER-2; keys on file-format-type, not getType()). Tests: new PluginDrivenScanNodeVerboseExplainTest (3 tests, CALLS_REAL_METHODS + Deencapsulation partial-node pattern, empty scanRangeLocations -> only the bare backends: header prints): non-paimon (max_compute) VERBOSE emits backends:, paimon still emits, NORMAL omits. RED->GREEN verified empirically: re-adding the gate turns the non-paimon test red (max_compute output lacks backends:). 45/0/0 PluginDrivenScanNode* UT + checkstyle clean; e2e gated/not-run.

    Why this matters (Rule 9 — tests encode WHY): the {@code backends:} block (the per-backend + * scan-range detail with {@code dataFileNum/deleteFileNum/deleteSplitNum}) is universal {@link FileScanNode} + * behavior: the parent emits it unconditionally under {@code VERBOSE && !isBatchMode()} + * ({@code FileScanNode#getNodeExplainString}).

That source-name gate (a) regressed + * cut-over MaxCompute VERBOSE EXPLAIN (legacy {@code MaxComputeScanNode extends FileQueryScanNode} inherited + * the unconditional block) and (b) violated the project rule that the generic SPI node must not branch on a + * connector source name. After cut-over, jdbc/es/trino-connector/max_compute/paimon all route through this + * node ({@code SPI_READY_TYPES}); the block must appear for all of them.

    + * + *

    MUTATION killed: re-introducing {@code && "paimon".equals(desc.getTable().getDatabase() + * .getCatalog().getType())} makes a non-paimon catalog (here {@code max_compute}) skip the block, so + * {@code "backends:"} disappears from VERBOSE EXPLAIN → {@link #verboseEmitsBackendsBlockForNonPaimonConnector} + * goes red. {@link #nonVerboseOmitsBackendsBlock} pins the surviving {@code VERBOSE} gate so a mutant that + * drops the level check (always emitting the block) is also killed.

Legacy + `MaxComputeScanNode extends FileQueryScanNode extends FileScanNode` and did **not** override + `getNodeExplainString` (verified in git `73832991962^`: class decl only, no override) → it inherited the + unconditional block.

Directly violates the project rule (memory + `catalog-spi-plugindriven-no-source-specific-code`): universal `FileScanNode` behavior must be emitted + unconditionally (like the sibling `inputSplitNum` / `partition=N/M` / `pushdown agg=` lines in this very + method), connector-specific behavior must delegate via `ConnectorScanPlanProvider.appendExplainInfo`. +3. **False comment.** The inline comment (`:299-304`) claims the gate keeps "es/jdbc/max_compute VERBOSE + output … byte-unchanged" — wrong: it is exactly what regresses MaxCompute. + +# Root Cause + +`PluginDrivenScanNode.getNodeExplainString` reimplements the `FileScanNode` body (custom +TABLE/CONNECTOR/QUERY/PREDICATES format, so it cannot call `super`) and re-emits each inherited line by +hand. For the VERBOSE backends block the re-emission was wrongly conjoined with a paimon source-name gate +(added by FIX-PAIMON-EXPLAIN-GAP `d4526013364`, with the stated but incorrect intent of "not perturbing +other connectors"), instead of mirroring the parent's gate verbatim (`VERBOSE && !isBatchMode()`). + +# Design + +Remove the `"paimon".equals(...)` conjunct. The remaining gate `detailLevel == VERBOSE && !isBatchMode()` +is then **identical to the parent `FileScanNode`'s** gate (`FileScanNode.java:151`).

No change there. + +## Who is affected — CORRECTED after design red-team (`wf_3518653b-3cb`) + +> The first draft of this doc wrongly scoped the change to "paimon + maxcompute" and claimed "es/jdbc: not +> routed → no change". The red-team **refuted** that with code evidence and I verified it independently. + +`CatalogFactory.java:51`: `SPI_READY_TYPES = {"jdbc", "es", "trino-connector", "max_compute", "paimon"}` — +**all five** become `PluginDrivenExternalCatalog` → `PluginDrivenExternalTable` → routed to +`PluginDrivenScanNode` (`PhysicalPlanTranslator:737`). A plain `SELECT … FROM _catalog.db.tbl` +reaches the table-scan **else**-branch (only the jdbc-**TVF** uses `PassthroughQueryTableHandle` → the +**if**-branch, unaffected). `supportsBatchScan` defaults `false` (only MaxCompute overrides it), so +`!isBatchMode()` is true for es/jdbc → the gate fires. So removing the conjunct emits the `backends:` block +for **all 5** SPI connectors. + +## Why this is safe (no NPE) + +- **Always file-based ranges.** `PluginDrivenScanNode` produces only `PluginDrivenSplit` (`extends + FileSplit`), so every `scanRangeLocations` entry carries a populated `FileScanRange` — exactly what + `appendBackendScanRangeDetail` dereferences (`locations.getScanRange().getExtScanRange() + .getFileScanRange().getRanges()`). es/jdbc render a synthetic per-split path (`es:///`, + `jdbc://virtual`); no real file, but NPE-safe. (red-team C-SAFE: confirmed, 4 independent verifiers.) +- **`getDeleteFiles` null-guard.** The block calls `getDeleteFiles(rangeDesc)`; the override returns empty + for a range without table-format params and for a null provider (guarded + unit-tested in + `PluginDrivenScanNodeDeleteFilesTest`). Non-paimon ranges → `deleteFileNum=0`, no NPE. +- **Empty scan.** If `scanRangeLocations` is empty the loop body never runs → only a bare `backends:` line + is printed (same as the parent today). No regression vs `FileScanNode`. +- **Batch-mode.** The one range shape with a null `getRanges()` (split-source-only) exists only when + `isBatchMode()==true`, and the block stays gated by `!isBatchMode()` (cached, shared by both paths). + +## Parity / behavioral delta + +- **paimon:** unchanged (was already in the gate; still emitted; `test_paimon_deletion_vector_oss` still + asserts `deleteFileNum`). Byte-identical. +- **maxcompute & trino-connector:** the `backends:` block reappears under VERBOSE — **restores** pre-cutover + legacy behavior (both legacy nodes extended `FileQueryScanNode` and inherited the unconditional block). +- **es / jdbc:** **NEW** VERBOSE output — their legacy dedicated scan nodes (`EsScanNode` / + `JdbcScanNode`) did not emit a `FileScanNode` backends block. This is the rule-mandated, consistent + choice: it is the same category as the sibling universal lines (`partition=N/M`, `pushdown agg=`) that + this override **already** emits unconditionally for es/jdbc.

A table existing ONLY remotely (absent from this FE's cache — stale cache / other-FE / external Spark/Flink create), created without IF NOT EXISTS, fell through to metadata.createTable -> DorisConnectorException -> re-wrapped as a generic DdlException (errno ERR_UNKNOWN_ERROR = 0). CREATE still failed, but the documented MySQL 1050 contract (some ORMs / migration tools branch on SQLSTATE 42S01) was lost. The bridge ported only the local arm's 1050 report. Both legacy ops reported 1050 for BOTH arms: legacy paimon PaimonMetadataOps.performCreateTable (remote :195, local :212) and legacy maxcompute MaxComputeMetadataOps.createTableImpl (remote :184, local :195). So 1050-for-remote is exact parity for both live cut-over connectors. Solution: drop the `if (localExists)` guard. Reaching that point already guarantees (remoteExists || localExists) && !isIfNotExists, so report ERR_TABLE_EXISTS_ERROR unconditionally there — short-circuiting before metadata.createTable (also keeps a local-cache-only conflict from being created remotely). Diagnostic/contract-only change (error code/SQLSTATE/message); the CREATE outcome (failure) is unchanged; metadata.createTable is no longer reached for a remote-existing table (it only threw anyway). For non-create-overriding connectors (es/jdbc/trino) a CREATE on an existing table now surfaces "already exists" instead of the old fall-through error — benign, arguably more accurate. Tests (PluginDrivenExternalCatalogDdlRoutingTest): rewrote testCreateTableExistingTableWithoutIfNotExistsStillErrors -> testCreateTableExistingRemoteTableWithoutIfNotExistsReportsErrno1050 (it encoded the buggy fall-through, verify(metadata).createTable); it now asserts getMysqlErrorCode() == ERR_TABLE_EXISTS_ERROR + verify(metadata, never()).createTable. Strengthened testCreateTableLocalConflictWithoutIfNotExistsRejects with the same errno assertion (the two together pin "report 1050 on EITHER arm"). RED->GREEN verified empirically: re-adding the guard turns the remote test red (buggy path falls through to the no-op mock createTable -> nothing thrown). 26/0/0 DdlRouting + 12/0/0 Engine UT + checkstyle clean; e2e gated/not-run.

Design + summary in plan-doc/designs/FIX-C4-R2-R3-CATALOG-{design,summary}.md. C4 (missing-port) — HMS metastore client socket-timeout was hardcoded "10" in the SPI move, ignoring Config.hive_metastore_client_timeout_second (metastore-spi has no fe-common dep). Thread the FE config value through ConnectorContext.getEnvironment() into HmsMetaStoreProperties.toHiveConfOverrides(String). Byte-identical "10" when fe.conf unset (Config default 10); an operator who raises it now gets the configured value (restores HMSBaseProperties:204-208). User-override guard unchanged; only the HMS branch threads it (DLF/JDBC/REST/FS have no socket-timeout default). R2-catalog (missing-port) — legacy PaimonExternalCatalog.checkProperties validated meta.cache.paimon.table.{enable,ttl-second,capacity} via CacheSpec; the plugin path dropped those checks. The keys are dead on the plugin path: a cut-over paimon table reports meta-cache engine "default" (ExternalTable.getMetaCacheEngine, not overridden by PluginDriven), so it never reaches PaimonExternalMetaCache (engine "paimon") which these keys size. Warn (not reject, not strip) in PaimonConnectorProvider.validateProperties — re-validating a dead knob is pointless and stripping would mutate persisted props; the key is paimon-specific so it lives in the connector, not the connector-agnostic bridge. R3-catalog (regression) — PaimonConnectorMetadata.listDatabaseNames swallowed remote failures to emptyList (a transient metastore failure showed as "zero databases"), with a comment falsely claiming legacy parity. Rethrow RuntimeException with the catalog name exactly as legacy PaimonMetadataOps:340 did, matching every other connector (all propagate). executeAuthenticated (M-11 Kerberos wrap) preserved; bridge does not catch, so it reaches DB-init as legacy did. Tests: paimon 280/0/0 (+1 gated skip); PaimonConnectorValidatePropertiesTest 14/0 (+R2 no-reject); PaimonConnectorMetadataReadAuthTest 12/0 (R3 swallow→rethrow migrated, M-11 coverage kept); HmsMetaStorePropertiesTest 16/0 (+3 C4); MetaStorePropertiesContractTest 3/0; fe-core compiles; checkstyle 0; connector import-check clean. Design + impl red-team both clean (0 actionable). e2e gated (enablePaimonTest=false), NOT run.

The connector's appendExplainInfo emitted only paimonNativeReadSplits= + VERBOSE PaimonSplitStats, and the generic node emits PREDICATES: (the Doris-level conjuncts), NOT the SDK-converted set. Since PaimonPredicateConverter silently drops unconvertible conjuncts (LTZ/FLOAT/ unsupported CAST), the pushed subset was no longer observable. Solution: in appendExplainInfo, deserialize the already-present paimon.predicate prop (the exact List pushed to BE, always serialized at getScanNodeProperties:579) and render the legacy block, placed between the paimonNativeReadSplits= line and the VERBOSE PaimonSplitStats block (exact legacy order PaimonScanNode:657-671). New private helper appendPredicatesFromPaimon. Chosen over re-running the converter: the filter is not in the SPI seam (carries only the props map) and the provider is re-instantiated per call (no field), so deserializing the existing prop is the smallest faithful change -- no SPI change, no new prop, no redundant serialization. Gated on paimon.predicate != null (absent != empty -> skip, preserving the existing exact-equality explain tests); decode failure -> LOG.warn + skip (never breaks EXPLAIN). Tests: 4 new PaimonScanExplainTest (build paimon.predicate exactly as production does): non-empty emit (exact-equality incl double-prefix indent), empty -> NONE, ordering (native < predicates < stats), absent -> skip.

Ruled out. +2. **The seam carries only a `Map`.** `ConnectorScanPlanProvider.appendExplainInfo(output, + prefix, nodeProperties)` — the filter/`ConnectorExpression` is NOT passed (it is available only at + `planScan`/`getScanNodeProperties` time). → Re-running the converter at explain time would require an + SPI signature change. Ruled out (keep connector-side, no SPI change). +3. **The pushed predicates are already serialized into the props.** `getScanNodeProperties:579` ALWAYS + emits `props.put("paimon.predicate", encodeObjectToString(predicates))` (even for the empty list — a + non-null base64 string; the JNI reader deserializes it unconditionally). `encodeObjectToString` + (`:1448`) = `InstantiationUtil.serializeObject` + Base64. +4. **`appendExplainInfo` receives those props.** The node does `explainProps = new HashMap<>(props)` + (`PluginDrivenScanNode.java:324`) where `props = getOrLoadScanNodeProperties()` (`:258`), then injects + the synthetic `__native_read_splits`/`__total_read_splits`/`__explain_verbose` keys + (`:325-328`, unconditional). So `paimon.predicate` is **always present** in `nodeProperties` during a + real EXPLAIN, and `InstantiationUtil.deserializeObject(byte[], ClassLoader)` is the symmetric inverse + (verified present in the SDK). +5. **Legacy ordering:** `super-body` → `paimonNativeReadSplits=/` → + `predicatesFromPaimon:[ NONE | …]` → `[VERBOSE] PaimonSplitStats:` (`PaimonScanNode.java:656-671`). + +## Design + +In the connector's `appendExplainInfo`, **deserialize the already-present `paimon.predicate` prop** back +to `List` and render the legacy `predicatesFromPaimon:` block, placed **between** the +`paimonNativeReadSplits=` line and the VERBOSE `PaimonSplitStats` block (exact legacy order).

In a real EXPLAIN it is always present (fact 3+4), +so this is full legacy parity. When absent (a unit test that injects only the synthetic keys, or another +connector's props) the line is skipped — which **preserves ALL existing exact-equality `appendExplainInfo` +tests** (none of them set `paimon.predicate`) and mirrors the existing "skip when keys absent" philosophy +of the `paimonNativeReadSplits=` line (`:1112-1114`).

That is not directly possible — the filter is not in the seam (fact 2). Deserializing the +already-serialized `paimon.predicate` is strictly better: same OUTPUT (the rendered pushed predicates), +but it renders **precisely what BE receives** (the serialized list is the source of truth), with the +smallest change (no SPI signature change, no new prop, no BE bloat). + +## Risk Analysis + +- **No correctness/perf/route impact** — diagnostic EXPLAIN text only. +- **Decode failure** never breaks EXPLAIN (try/catch → LOG.warn + skip the line). +- **No redundant serialization** — reuses the existing `paimon.predicate` blob instead of serializing the + same `List` into a second prop.

Memoizing the built ConnectorTableSchema would cache the live coreOptions under a schemaId key and could serve stale PROPERTIES (red-team MAJOR) — so only the raw PaimonSchemaSnapshot (a pure function of the key) is cached. No perf regression (hard constraint): the cached value is a pure function of the key (a committed schemaId's schema is write-once); the latest path never builds a key; worst case (miss / eviction / concurrent double-load) = the pre-fix per-query load. The only behavioral delta is "the schemaAt read is skipped on a repeat". Tests: +3 PaimonConnectorMetadataMvccTest (cross-query hit / schemaId-keyed / branch-keyed) and new PaimonSchemaAtMemoTest (dedup / sysName-keyed / overflow-re-read); each RED-verified by a separate mutation run (memo-disabled, key-drops-fields, bound-disabled). Full paimon module 293/0/0/1skip, checkstyle 0, check-connector-imports 0. e2e gated (enablePaimonTest=false) NOT run.

Diagnostic/perf only, no correctness impact — but the user elected to fix +it (restore the legacy hit) rather than accept-as-deviation. + +## Root cause + +`PaimonConnector.getMetadata(session)` returns a **fresh** `new PaimonConnectorMetadata(...)` on every +call (`PaimonConnector.java:94-97`), and fe-core calls `getMetadata(session)` **once per query** +(`PluginDrivenMvccExternalTable.java:122,218` and every other call site). So the metadata object is a +per-query throwaway: nothing on it persists the at-snapshot schema across queries. The legacy cache lived +on the long-lived catalog-level metacache; the cutover has no equivalent on the time-travel path. + +**Consequence for the fix's home (critical):** a memo stored as an *instance field of +`PaimonConnectorMetadata`* would give **zero** cross-query benefit (it would die with the per-query +metadata object after its single `schemaAt`). The memo's **storage must live on the long-lived +`PaimonConnector`** (one per catalog), and be *injected into* the per-query metadata so the at-snapshot +resolve can consult/populate it. (`PaimonTableResolver` is a stateless static utility — `final class`, +private ctor — so it is NOT a home for cross-query state.) + +## Design + +**Connector-side, immutable, bounded memo of the `schemaAt` read. Bridge UNCHANGED. SPI UNCHANGED.** + +### What is memoized (post-red-team): the raw `PaimonSchemaSnapshot`, NOT the built `ConnectorTableSchema` + +The red-team (MAJOR, REAL) showed the built `ConnectorTableSchema` is **not** a pure function of the +schemaId key: `buildTableSchema` sources its `properties` from the **live** table — +`schemaProps.putAll(((DataTable) table).coreOptions().toMap())` (`PaimonConnectorMetadata.java:251-252`), +where `table = resolveTable(handle)` is the LATEST table. Caching the built schema would freeze the live +`coreOptions` under a schemaId key and could serve stale PROPERTIES after an external `ALTER…SET OPTION` +without REFRESH (D-046 SHOW CREATE TABLE PROPERTIES channel) — a violation of "never return stale data +than today". + +So we memoize the **`PaimonCatalogOps.PaimonSchemaSnapshot`** (fields + partitionKeys + primaryKeys — +the exact output of the `schemaAt` schema-file read), which **IS** a pure function of +`(table-identity, schemaId)` (a committed schemaId's schema content is write-once). `ConnectorTableSchema` +is rebuilt fresh per query from the live `resolveTable` table, so `coreOptions`/`properties` stay LIVE = +byte-identical to today. The ONLY behavioral delta vs today is: **the `schemaAt` schema-file read is +skipped on a repeat**. `resolveTable` and `buildTableSchema` still run every query (unchanged). + +### Components + +1. **New tiny class `PaimonSchemaAtMemo`** (package-private, in `fe-connector-paimon`): + - Storage = plain **`ConcurrentHashMap`** (matches the + module convention — the only long-lived caches in fe-connector-paimon are plain `ConcurrentHashMap`, + `PaimonConnector.java:81-82`; lock-free reads; no new dependency). + - **`MemoKey`** = immutable holder of the handle's **extracted identity** `(databaseName, tableName, + sysTableName, branchName, schemaId)` built in `new MemoKey(PaimonTableHandle handle, long schemaId)`. + It mirrors `PaimonTableHandle.equals/hashCode`, which key on exactly + `(databaseName, tableName, sysTableName, branchName)` (`PaimonTableHandle.java:233-240`, `scanOptions` + correctly excluded from identity). **Extracted fields, NOT a retained handle reference** — deliberate: + a `PaimonTableHandle` carries its loaded paimon `Table` (`setPaimonTable`), so retaining the handle as + a map key would pin that `Table` (catalog/schema/IO refs) in the cache for its lifetime. Extracting the + four `String`/`long` identity fields avoids that memory pin at the cost of a documented sync-point with + the handle's identity (a comment in `MemoKey` points to `PaimonTableHandle:233-240`). This is a + deliberate deviation from the red-team's "delegate to handle.equals" suggestion, which did not account + for `Table`-pinning. Branch is load-bearing (same schemaId on different branches = different schema; + `branchName` is live on the pinned handle via `applySnapshot→withBranch`). `sysName` is a forward-compat + guard (sys tables don't reach this path today, but a key collision would be a correctness bug). + - **Bound (best-effort, honors task-list "bounded (maxSize)"):** before a `put`, if `size() >= MAX`, + `clear()` the map. Crude but correct: values are immutable, so a flush only causes re-reads + (= today), never a stale/wrong value. The keyspace is `(table, branch, schemaId)` — naturally tiny — + so this safety valve effectively never fires; `MAX` is a generous constant (proposed `10000`). The + map is also freed wholesale on REFRESH (connector rebuild). + - `PaimonSchemaSnapshot getOrLoad(PaimonTableHandle handle, long schemaId, Supplier loader)`: + ``` + MemoKey k = new MemoKey(handle, schemaId); + PaimonSchemaSnapshot hit = cache.get(k); // lock-free + if (hit != null) return hit; + PaimonSchemaSnapshot loaded = loader.get(); // the schemaAt I/O — OUTSIDE any lock + if (cache.size() >= MAX) { // best-effort bound + cache.clear(); + } + PaimonSchemaSnapshot prev = cache.putIfAbsent(k, loaded); + return prev != null ? prev : loaded; // canonicalize on a concurrent race + ``` + The loader runs without any lock (no I/O-under-lock, no `computeIfAbsent`). A concurrent same-key + miss may double-load (rare) — harmless: the value is immutable and identical (same schemaId), and a + double-load equals today's two independent per-query loads, never worse. A loader exception + propagates BEFORE any `put`, so failures are never negative-cached. + +2. **`PaimonConnector`**: add `private final PaimonSchemaAtMemo schemaAtMemo = new PaimonSchemaAtMemo(MAX);` + and pass it into the metadata: `new PaimonConnectorMetadata(catalogOps, properties, context, schemaAtMemo)`. + The connector is one-per-catalog and set to `null` on `onClose()` + (`PluginDrivenExternalCatalog.java:557`), which REFRESH CATALOG triggers via + `resetToUninitialized()→onClose()`; the next access rebuilds the connector → **fresh empty memo**. So + REFRESH is the (only needed) invalidation. + +3. **`PaimonConnectorMetadata`**: + - New **package-private** 4-arg ctor `(catalogOps, properties, context, schemaAtMemo)` storing the memo. + Package-private (not public) keeps the connector surface minimal (Rule 3); the cross-query-hit test + lives in the same package `org.apache.doris.connector.paimon` and constructs both metadata instances + through it with a shared `PaimonSchemaAtMemo`. + - Keep the existing **public** 3-arg ctor delegating to the 4-arg with a **fresh per-instance** + `new PaimonSchemaAtMemo(MAX)`. This keeps all ~15 existing test construction sites compiling + unchanged; their single-resolve behavior is identical (first call is always a miss → load). + - In `getTableSchema(session, handle, snapshot)` (the at-snapshot overload), the **only** change is the + `schemaId >= 0` branch (the `< 0` latest fallback at line 216-217 is untouched). **`resolveTable` is + called ONCE, outside the loader**, so the branch-handle `getTable` reload happens at most once per + query = today: + ``` + PaimonTableHandle paimonHandle = (PaimonTableHandle) handle; + long schemaId = snapshot.getSchemaId(); + Table table = resolveTable(paimonHandle); // once — keeps branch getTable == today + PaimonCatalogOps.PaimonSchemaSnapshot schema = + schemaAtMemo.getOrLoad(paimonHandle, schemaId, () -> catalogOps.schemaAt(table, schemaId)); + return buildTableSchema(paimonHandle.getTableName(), table, + schema.fields(), schema.partitionKeys(), schema.primaryKeys()); + ``` + +## NO-regression argument (must hold + WAS red-team-verified) + +1. **The memoized value is a pure function of the key → no stale read, no TTL.** We cache only + `PaimonSchemaSnapshot` (fields/partitionKeys/primaryKeys of a *committed* schemaId), which is write-once + in paimon (rollback/ALTER mint *new* ids; a re-pointed tag resolves a *new* schemaId at resolve-time → + a different key, never a stale hit). The live-bound `coreOptions`/`properties` are NOT cached — they are + rebuilt per query from the live table, so they stay current (the red-team MAJOR that killed the + `ConnectorTableSchema`-memo). The only invalidation is REFRESH CATALOG (connector rebuild → fresh memo). +2. **Latest path untouched.** The memo is consulted **only** on the `schemaId >= 0` at-snapshot branch. + `schemaId < 0` (latest / system tables) still delegates to `getTableSchema(session, handle)` (line + 216-217), cached cross-query by the bridge's generic schema cache (`getSchemaCacheValue → + getLatestSchemaCacheValue → super`). The 2-arg latest `getTableSchema` (called from + `PluginDrivenExternalTable:172`) is untouched — no double-caching. +3. **Worst case = current.** On a miss: `resolveTable` + `schemaAt` + `buildTableSchema` (= today) + an + O(1) hash put. On a hit: `resolveTable` + `buildTableSchema` (= today) with the `schemaAt` read + **skipped** (strictly faster, = legacy). On overflow/eviction or a concurrent double-load: a re-read = + today.

Legacy paimon set both, so FederationBackendPolicy distributed splits across BEs by proportional (by-size) weight. FE BE-assignment only — no rows/route/BE-read/result change. The task-list's "already computed, just not threaded" held only for JNI/count splits. Two gaps: 1. The connector's NATIVE ranges (buildNativeRange) never set selfSplitWeight (Builder default 0). Legacy native sub-splits used selfSplitWeight = length (+ deletionFile.length()) (PaimonSplit:72,112). Native ORC/Parquet is the default read path, so weight 0 would clamp to 0.01 (uniform) and defeat the fix. 2. The weight denominator (legacy PaimonScanNode:499 = fileSplitSize>0 ? : max_file_split_size, 64MB default) is a DIFFERENT value from the connector's file-splitting targetSplitSize, carried nowhere. Fix: - SPI ConnectorScanRange: new default getters getSelfSplitWeight()/getTargetSplitSize(), sentinel -1 = "not provided". Connector-agnostic — all 6 non-paimon impls (jdbc/es/trino/maxcompute/hive/hudi) inherit -1 -> keep standard() (no regression). - PluginDrivenSplit ctor: set the FileSplit fields only when weight>=0 && target>0 (0 is a real weight; target>0 guards div-by-zero). Generic, no source-specific branching. - PaimonScanRange: new targetSplitSize field (default -1) + Builder + @Override getTargetSplitSize(); getSelfSplitWeight() marked @Override. - PaimonScanPlanProvider: resolveSplitWeightDenominator(session) (exact legacy formula), computed once and threaded as weightDenominator (named to avoid transposing with the file-split target) to every builder; buildNativeRange now sets selfSplitWeight = length + DV and targetSplitSize = weightDenominator; JNI/count add targetSplitSize. Applied to every split type incl. count pushdown. FE-only: the BE-thrift paimon.self_split_weight (A3) stays gated on paimonSplit != null, so native ranges still emit nothing to BE. Tests: fe-core PluginDrivenSplitWeightTest (W=50/T=100->50, clamp->1, 0-weight->1, -1 sentinel->standard, one-field-only->standard); fe-connector-api ConnectorScanRangeWeightDefaultsTest (-1 defaults); connector +5 PaimonScanPlanProviderTest (sentinel/round-trip, native weight=length+DV, positional-swap guard, count-pushdown denominator, denominator formula) + updated the 6 changed-signature call-sites.

Computed once in `planScanInternal` (session-only), passed to every builder. + - The threaded param + local is named **`weightDenominator`** EVERYWHERE (never `targetSplitSize`) so it + cannot transpose with the existing file-splitting `targetSplitSize` / `effectiveSplitSize` local — a + two-adjacent-`long` positional-swap is the one real bug risk here, name-isolated by construction. + - `buildNativeRange`: `.selfSplitWeight(length + (deletionFile != null ? deletionFile.length() : 0))` + (legacy `selfSplitWeight = length` + `+= deletionFile.length()`), `.targetSplitSize(weightDenominator)`. + - `buildJniScanRange` / `buildCountRange`: add `.targetSplitSize(weightDenominator)` (selfSplitWeight already set). + - Thread `weightDenominator` as an explicit param through `buildNativeRanges`/`buildNativeRange`/ + `buildJniScanRange`/`buildCountRange`.

The connector owning its denominator is both simpler and + correct; do NOT later "simplify" the SPI getter away. + +## No-regression / correctness + +- **Other connectors unchanged:** sentinel `-1` default → `PluginDrivenSplit` leaves both FileSplit fields + null → `getSplitWeight()` = `standard()` exactly as today. Verified **all 6 non-paimon + `ConnectorScanRange` impls (jdbc / es / trino / maxcompute / hive / hudi)** do not reference/override the + new getters → inherit the `-1` sentinel → `standard()`.

From 60ed665c4dc73a5e95af0ca59c1ebaad99a95b7c Mon Sep 17 00:00:00 2001 From: morningman Date: Fri, 19 Jun 2026 18:55:00 +0800 Subject: [PATCH 119/128] =?UTF-8?q?fix:=20FIX-B-R2-be=20=E2=80=94=20memoiz?= =?UTF-8?q?e=20the=20schema-evolution=20dict's=20per-schema-id=20reads?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: buildSchemaEvolutionParam builds BE's history_schema_info dict by reading EVERY committed schema (schemaManager.listAllIds() + schema(id).fields()) on every scan, even when the query's files touch a single schema. Legacy added entries lazily per referenced file schema_id. The task-list's "narrow to referenced ids" is architecturally infeasible connector-only and BE-crash-prone: getScanPlanProvider() returns a NEW provider per call (so planScan's split schema_ids can't reach the dict build); the dict builds lazily and often BEFORE splits are planned; the referenced set is per-scan; the generic bridge must not collect paimon.schema_id; re-planning in props is forbidden (new I/O); and an under-covering set hard-crashes BE (table_schema_change_helper.h fail-loud, cf. CI 969249). The user chose Option A: memoize the reads, keep the eager superset emission. Fix: keep listAllIds() and the dict emission BYTE-IDENTICAL (full superset always covers any file's schema_id -> zero BE-crash risk); only the per-schema-id field READ is served from a connector-level immutable memo. Reuse the existing B-MC2 PaimonSchemaAtMemo (it already caches (handle,schemaId)->schema fields, write-once, cleared on REFRESH; the cached fact is identical, so one cache serves both the time-travel path and the dict). PaimonScanPlanProvider gains a package-private 4-arg ctor taking the memo (2/3-arg ctors delegate with a fresh memo -> existing sites unchanged); buildSchemaEvolutionParam takes the handle and memo-wraps the listAllIds loop with a DIRECT-read loader (schemaManager.schema(id) -> PaimonSchemaSnapshot, NOT catalogOps.schemaAt, so real-table+fake-catalogOps tests are unaffected); the -1 current entry stays a live read. PaimonConnector.getScanPlanProvider() injects the same per-catalog memo getMetadata uses. Consistency (same key -> same value across both features) verified by design red-team + impl-verify: the cached fact is the write-once committed schema- file, identical regardless of which Table instance's schemaManager reads it; MemoKey excludes scanOptions and mirrors PaimonTableHandle identity exactly; B-MC2 never writes a $ro/sys key.

Both features call the SAME underlying read +`schemaManager.schema(schemaId)`. Caching it ONCE and serving both the time-travel path (B-MC2) and the +schema-evolution dict (this fix) is the DRY, efficient design. + +**Consistency proof (same key → same value across the two features) — MUST hold. PRIMARY proof = the +write-once invariant (NOT object identity):** +- **Write-once invariant (the load-bearing argument):** for any committed `schemaId`, + `schemaManager.schema(schemaId)` reads the **immutable, write-once `schema-` file** — its content is + independent of WHICH `Table` instance's `schemaManager` reads it (B-MC2's UNPINNED `resolveTable`, or this + fix's snapshot-PINNED `resolveScanTable` = `table.copy(scan.snapshot-id=…)`). `MemoKey` deliberately + excludes `scanOptions` from identity (`PaimonTableHandle.equals`), so the pinned and unpinned reads + legitimately share ONE key, and the `scan.snapshot-id` pin does NOT change which committed schema file a + given `schemaId` resolves to. So the same `MemoKey` always yields the same `fields()`. (Object identity of + the `Table` is NOT required and does NOT hold for a time-travel scan — only value-equality, which the + write-once invariant guarantees.) +- `$ro`: B-MC2 NEVER writes `$ro` keys (system tables skip the at-snapshot path — `resolveTimeTravel`/ + `beginQuerySnapshot` return empty for sys, and `getTableSchema(snapshot)` short-circuits on the default + `schemaId<0`). This fix writes the BASE table's schema under the `$ro`-handle key (handle sysName="ro", + `schemaDictTable`=base). No B-MC2 value to conflict; internally consistent. (Minor: a `t` query and a + `t$ro` query don't share — different sysName — so `$ro` re-reads the base schemas once. Acceptable; rare.) +- branch: both writers key by `(db, table, branch)` and both read the branch FileStoreTable's + `schemaManager.schema(id)` (the same write-once branch schema file) — identical value. + +**Loader keeps the DIRECT read (not `catalogOps.schemaAt`)** so the existing real-`FileStoreTable` + +fake-`catalogOps` tests are unaffected (the schema-evolution tests build a real `FileStoreTable` via +`FileSystemCatalog` but construct the provider with a `RecordingPaimonCatalogOps`; routing the read through +`catalogOps.schemaAt` would break them).

Cleared + only on REFRESH (connector rebuild → fresh memo). No TTL, no stale read. +3. **Worst case = current.** Miss → the same direct read as today + an O(1) put; hit → the read is skipped + (faster, the win); overflow/concurrent-double-load → a re-read = today. Never more work than today. +4. **No new I/O, order-independent.** The memo does not depend on planScan/props ordering (unlike + narrowing); `listAllIds()` still runs each scan (a cheap directory listing — unchanged); only the + per-schema-file reads are cached. + +## Files + +- `fe-connector-paimon/.../PaimonScanPlanProvider.java` (ctor + field + `buildSchemaEvolutionParam` memo + thread handle) +- `fe-connector-paimon/.../PaimonConnector.java` (`getScanPlanProvider` injects `schemaAtMemo`) +- `fe-connector-paimon/.../test/.../PaimonScanPlanProviderTest.java` (new memoization test) + +## Test Plan (RED→GREEN; red-team's 6 findings folded in) + +1. **Dict build populates the shared memo (core RED→GREEN):** evolve a real `FileStoreTable` to K committed + schemas (via `FileSystemCatalog`, like the existing schema-evolution tests; `Catalog.alterTable` + + `SchemaChange.addColumn`); build a provider with a shared `PaimonSchemaAtMemo` (4-arg ctor); call + `getScanNodeProperties` → assert `memo.size() == K` (the K historical entries were read through the memo; + the `-1` entry does NOT use it). **RED before:** `buildSchemaEvolutionParam` reads directly → `size == 0`. + Also assert the memo's KEY SET is exactly `{(handle,0..K-1)}` (not just the count). +2. **Cache HIT is positively observable (sentinel pre-seed — fixes the false-pass gap):** seed the SHARED + memo for ONE `(handle, schemaId=X)` with a **sentinel** `PaimonSchemaSnapshot` whose field list DIFFERS + from the real schema (e.g. a renamed/extra `DataField` "SENTINEL_FROM_MEMO") via `memo.getOrLoad(handle, + X, () -> sentinel)`; then call `getScanNodeProperties`, **decode** the emitted `paimon.schema_evolution` + (via `applySchemaEvolutionParam` like the existing `$ro` test at `:602`), and assert the schemaId=X entry + carries the SENTINEL field (proving the build returned the CACHED value and skipped the real + `schemaManager.schema(X)` read). **RED before:** the real read overwrites → no SENTINEL → fails. +3. **Byte-identical emission vs the NON-memo baseline (safety):** on the SAME evolved table, capture + `encodedA` from a provider built with the 2/3-arg ctor (fresh per-instance memo → first build = direct + read = pre-fix behavior) and `encodedB` from the 4-arg-ctor provider (shared memo); assert + `encodedA.equals(encodedB)`. Proves the memoized path emits a byte-identical dict (no order/dedup/membership + change → zero BE-crash surface). The existing schema-evolution / `$ro` tests also stay green (2-arg ctor). +4. **force-JNI → memo NOT populated:** with a shared memo, call `getScanNodeProperties` (a) on a force-jni + handle (`isForceJni()`, e.g. a binlog sys handle) and (b) with `force_jni_scanner=true` + (`sessionWithProps`) → assert `paimon.schema_evolution` ABSENT AND `memo.size()==0` (the dict — and the + read — is gated off; guards a future regression moving the read above the gate). +5. **Connector wiring (the perf benefit hinges on ONE edit):** assert `connector.getScanPlanProvider()` and + `connector.getMetadata()` observe the SAME `PaimonSchemaAtMemo` instance, and two successive + `getScanPlanProvider()` calls share it — pins the `getScanPlanProvider` 4-arg injection so the fix can't + silently no-op (fresh per-provider memo) while still emitting a correct dict.

From 2612af5e88fb7388cfaf17681dfa89fccf42b449 Mon Sep 17 00:00:00 2001 From: morningman Date: Fri, 19 Jun 2026 19:56:47 +0800 Subject: [PATCH 121/128] =?UTF-8?q?fix:=20P2-T04=20=E2=80=94=20MetaStorePr?= =?UTF-8?q?oviders=20ServiceLoader=20uses=20the=20SPI's=20own=20classloade?= =?UTF-8?q?r,=20not=20TCCL?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CI external 973270 (commit 13d3876): all 37 paimon-family tests failed at CREATE CATALOG with 'No MetaStoreProvider supports the given properties; registered providers: []'. Root cause: MetaStoreProviders.PROVIDERS is a static field loaded once via the 1-arg ServiceLoader.load(MetaStoreProvider.class), which resolves against the thread-context classloader. Its first touch is PaimonConnectorProvider.validateProperties at CREATE CATALOG time, running on an FE worker thread whose TCCL is the FE app loader. fe-core does not depend on fe-connector-metastore-spi, so the 5 providers and their META-INF/services file live only inside the connector plugin's child classloader; the lookup finds nothing and caches an empty list process-wide, so every paimon CREATE CATALOG fails. (The sibling PaimonConnector.createCatalogFromContext already pins the TCCL for the same reason; the validation path did not.) Fix: load via the 2-arg ServiceLoader.load(MetaStoreProvider.class, MetaStoreProvider.class.getClassLoader()) — the interface's defining loader is the plugin loader that has the service file and impls, independent of the caller's TCCL.

Axis A (data snapshot): - new PaimonLatestSnapshotCache on the per-catalog PaimonConnector: TTL cache of the latest snapshot id keyed by Identifier(db,table), sized by meta.cache.paimon.table.ttl-second (legacy default 86400; <=0 disables -> always live = the no-cache catalog), access-based expiry. Injected into PaimonConnectorMetadata (new 5-arg ctor; the 3/4-arg ctors get a disabled cache so existing direct-construction tests are unchanged). - beginQuerySnapshot serves the id through the cache (live read only on a miss). The pinned id reaches the scan via applySnapshot -> scan.snapshot-id -> resolveScanTable Table.copy, so an external write after the pin is invisible until expiry/refresh. - new Connector.invalidateTable/invalidateAll SPI default no-ops; PaimonConnector overrides them; RefreshManager.refreshTableInternal invalidates any PluginDrivenExternalCatalog's connector (keyed by REMOTE names). REFRESH CATALOG already rebuilds the connector. Axis B (schema TTL): - new Connector.schemaCacheTtlSecondOverride() SPI default empty; PaimonConnector returns meta.cache.paimon.table.ttl-second when set. - new generic ExternalCatalog.overlayMetaCacheConfig hook (no-op); PluginDrivenExternalCatalog overrides it to set schema.cache.ttl-second from the connector override (user value wins); ExternalMetaCacheMgr.findCatalogProperties applies it to its EPHEMERAL property copy (no SHOW CREATE leak). REFRESH TABLE already invalidates the schema cache entry. So the no-cache catalog (ttl-second=0) serves fresh schema. fe-core stays connector-agnostic (virtual dispatch; base no-ops). ttl-second removed from the PaimonConnectorProvider "dead keys" warning (it again takes effect); enable/capacity remain not-wired (still reported ignored). tests: PaimonLatestSnapshotCacheTest 5/5 (cache within TTL / ttl=0 bypass / invalidate / expiry via injected clock), PaimonConnectorCacheTest 4/4 (schemaCacheTtlSecondOverride mapping); regression PaimonConnectorMetadataMvccTest 40/40, ValidateProperties 14/14, fe-core compiles + PluginDrivenMvccExternalTableTest 36/36 + ListPartitionItemTest 2/2; checkstyle clean across the 3 touched modules. Cross-query data cache + schema TTL + refresh are gated by the docker e2e (enablePaimonTest=true rerun of test_paimon_table_meta_cache).

FIX-1/FIX-2 held; FIX-3 was itself a regression and FIX-4 did not fix its target. Two root causes, four failing suites (all test .out byte-identical to master -> master is the spec). Root causes: - FIX-3 (26a8ecd) patched only the genuine-null partition DISPLAY name on the SHARED ListPartitionItem.toPartitionKeyDesc. It never touched the MTMV refresh predicate (so test_paimon_mtmv still failed, now 5 rows vs master's 3), and it renamed hive's default partition p_NULL -> p_HIVEDEFAULTPARTITION, breaking test_hive_default_mtmv (asserts p_NULL) and test_upgrade_downgrade_mtmv (the MTMV.calculatePartitionMappings join needs both sides to render symmetrically). - The paimon bridge marked genuine-null isNull=true (1b0ae1ed), coupling two opposite needs through one flag: WHERE IS NULL prune wants true, MTMV refresh wants false (master PaimonUtil uses isNull=false unconditionally and loses the null data; IS NULL still works via the predicate-driven scan). - test_paimon_table_meta_cache: the SPI routes the latest schema through the generic name-keyed schema cache (no schemaId) whose TTL spec is frozen at first build (AbstractExternalMetaCache.initCatalog computeIfAbsent), so ttl-second=0 cannot bust it after an external ALTER -> stale schema. Fix (master parity; unit-tested, checkstyle clean; docker e2e still gated): - A1 revert FIX-3: ListPartitionItem.java restored byte-identical to master; ListPartitionItemTest now asserts the master p_NULL rendering. - A2 paimon bridge PluginDrivenMvccExternalTable.toListPartitionItem -> new PartitionValue(value, false), matching master PaimonUtil. The genuine-null MTMV partition is a StringLiteral sentinel (no p_NULL collision) and its refresh IN-predicate drops the null rows (3 rows, master parity). - A3 new connector capability ConnectorScanPlanProvider.ignorePartitionPruneShort Circuit() (default false; PaimonScanPlanProvider -> true), consulted by PluginDrivenScanNode.resolveRequiredPartitions: a predicate-driven connector maps a prune-to-zero to scan-all instead of the empty short-circuit. Required so WHERE col IS NULL still returns the genuine-null row under isNull=false (qt_null_partition_4) -- the branch short-circuits empty pruned sets where master's PaimonScanNode re-plans from the pushed predicate. - B PluginDrivenMvccExternalTable.getLatestSchemaCacheValue: when the connector disables its schema cache (schemaCacheTtlSecondOverride <= 0, the no-cache catalog) read the schema FRESH via initSchema(), bypassing the frozen name-keyed cache; the cached catalog keeps the cached path. Restores master's single-knob meta.cache.paimon.table.ttl-second=0 -> always-fresh-schema. Docker gate (enablePaimonTest/enableHiveTest=true): test_paimon_mtmv->3 rows; qt_null_partition_4->`1 \N 100.0` (must stay green); test_hive_default_mtmv-> p_NULL; test_upgrade_downgrade_mtmv->sync true; test_paimon_table_meta_cache-> no-cache desc 3 cols.

Root cause (master test .out is the spec): the connector's LATEST schema path read table.rowType(). paimon's CatalogFactory.createCatalog wraps a CachingCatalog (cache.enabled defaults true), so catalog.getTable() returns a cached Table whose rowType() is FROZEN at load time; only latestSnapshot()/schemaManager() read files fresh. That is why the no-cache DATA path was fresh (snapshot re-read) while the SCHEMA path was stale. An ALTER ADD COLUMNS bumps the schema file (new schema id) WITHOUT a new snapshot, so the latest snapshot's schemaId also stays behind — only schemaManager().latest() advances. Legacy PaimonExternalTable read the latest schema via schemaManager().latest() (never rowType()); the SPI cutover regressed to rowType(). Fix (connector-local, master parity): PaimonConnectorMetadata.getTableSchema (latest path) reads the latest schema FRESH via a new PaimonCatalogOps.latestSchema seam (((DataTable) table).schemaManager().latest()) for a non-system data table; partition and primary keys come from that resolved schema too. Dual guard: system tables (isSystemTable()) keep their synthetic rowType() — some are not DataTable ($snapshots/$manifests) and the DataTable-backed ones ($ro/$audit_log/$binlog) need the synthetic schema; a non-DataTable backend (FormatTable) / schema-less table -> latestSchema empty -> fall back to rowType(). This also fixes the with-cache REFRESH assertion (line 117): REFRESH busts the FE schema cache but not the paimon CachingCatalog, so only schemaManager().latest() reflects the external change. TDD: RED getTableSchemaReadsLatestSchemaNotCachedRowType (expected 3 but was 2, same symptom as CI) -> GREEN; plus sys-table guard + empty-latest fallback tests. Paimon module 318/0/0 (1 live-connectivity skip), checkstyle 0. e2e docker-gated (enablePaimonTest=true) NOT run.
