From 2198f314e5f7c52312037f2ff794a134d2a9460a Mon Sep 17 00:00:00 2001 From: Siew Kam Onn Date: Sun, 12 Apr 2026 16:35:52 +0800 Subject: [PATCH 01/15] Optimize Parquet pruning with reusable setup cache Add a scan-local ParquetPruningSetupCache in opener.rs to reuse adapted projection, adapted predicate, and row-group pruning predicate setup for same-schema files. Implement PhysicalExprAdapterFactory::supports_reusable_rewrites() in schema_rewriter.rs to allow default adapters while defaulting custom ones to opt-out. Connect the cache to ParquetMorselizer in source.rs and introduce a regression test to ensure the setup is reused correctly across same-schema files while keeping it conservative to avoid per-file literal replacements. --- .../datasource-parquet/src/opener/mod.rs | 326 ++++++++++++++---- datafusion/datasource-parquet/src/source.rs | 1 + .../src/schema_rewriter.rs | 13 + 3 files changed, 279 insertions(+), 61 deletions(-) diff --git a/datafusion/datasource-parquet/src/opener/mod.rs b/datafusion/datasource-parquet/src/opener/mod.rs index 87ec341f590da..76b470bdfa802 100644 --- a/datafusion/datasource-parquet/src/opener/mod.rs +++ b/datafusion/datasource-parquet/src/opener/mod.rs @@ -46,7 +46,7 @@ use std::collections::{HashMap, VecDeque};

DataFusion's [`MemoryPool`] deliberately accounts for only the "large" -//! allocations that scale with input size; intermediate batches flowing between -//! operators are assumed to be small and are left untracked.

Nothing reports what that overhead actually is, because the peak reservation -//! itself is never recorded — [`MemoryPool::reserved`] is a live value that has -//! usually fallen back to zero by the time a query finishes.

When a scan's projection consumes a nested column only through a cast to a -//! *narrower* nested type, for example the file contains -//! `events: List>` but the expression is -//! `CAST(events AS List>)`, the Parquet reader does not need to -//! fetch or decode the leaves the cast target never names. This module -//! computes which Parquet leaves survive such a cast, and the Arrow type the -//! reader will emit for them, by walking the physical and target type trees -//! in parallel and matching struct fields by name (the equivalent of Spark's -//! `ParquetReadSupport.clipParquetSchema`). -//! -//! This situation arises whenever a table's logical schema declares a nested -//! column narrower than the physical Parquet file: the physical expression -//! adapter rewrites the projected column into exactly such a whole-column -//! cast (see `datafusion_physical_expr_adapter`). Engines like Spark -//! communicate nested projection pruning to the scan this way, as a clipped -//! read *schema* rather than as `get_field` expressions. -//! -//! # Safety of clipping -//! -//! The runtime cast for nested types -//! ([`datafusion_common::nested_struct::cast_column`]) consumes source struct -//! children exclusively by looking up the *target* field names, recursively -//! through list wrappers. Physical subtrees not named by the target are -//! provably dead: removing them from the read cannot change the cast's -//! output. That holds for *any* -//! [`CastExpr`](datafusion_physical_expr::expressions::CastExpr) over a -//! nested type, not just the ones the schema adapter inserts: -//! `ColumnarValue::cast_to` routes every -//! cast for which -//! [`requires_nested_struct_cast`](datafusion_common::nested_struct::requires_nested_struct_cast) -//! holds, the same predicate the projection analysis gates on, through -//! `cast_column`. -//! -//! Struct-level nullability is preserved because the Parquet reader -//! reconstructs ancestor validity from the definition levels of any surviving -//! leaf, so every struct level that is clipped must keep at least one leaf. -//! A struct cast with zero field-name overlap at *any* nesting depth would -//! break that: the reader drops a field whose leaves are all masked out, so -//! the emitted type would not match the one predicted here. Such a cast is -//! rejected during physical planning -//! (`datafusion_common::nested_struct::validate_struct_compatibility`, called -//! recursively from `DefaultPhysicalExprAdapter::rewrite`) and by the logical -//! planner's own castability check, so it should never reach this module; if -//! one does anyway (a custom `PhysicalExprAdapter` could build one), -//! [`clip_for_cast`] detects the empty level and declines to clip. -//! -//! The clip is *total*: any type shape it does not understand (maps, -//! dictionaries, wrapper-kind mismatches, ...) keeps all of its leaves, so -//! the worst case is today's behavior of reading the full column. Map values -//! are deliberately not clipped: the runtime cast routes maps through Arrow's -//! positional struct cast, which requires all children to be present. Nor are -//! `ListView`/`LargeListView`/`Dictionary` wrappers clipped here, even though -//! `cast_column` does recurse through them by name.

Fast membership tests for small, fixed-width primitive `IN` lists. -//! -//! # Why use a branchless filter? -//! -//! For a short list such as `x IN (10, 20, 30)`, it can be faster to compare -//! `x` with all three values than to build and search a hash table. -//! -//! "Branchless" means that the filter always checks every list value. It -//! combines the answers with `|`, while `||` would stop at the first match. -//! This regular sequence of comparisons is easier for the compiler and CPU to -//! optimize. -//! -//! # How does it work? -//! -//! When the filter is built, it stores the non-null list values and chooses a -//! comparison function for that list length. Only this small function is -//! specialized for each length. The rest of [`BranchlessFilter`] is shared, -//! which keeps the generated code small. -//! -//! Some Arrow types share the same in-memory representation. For example, a -//! `Float32` and a `UInt32` both use four bytes per value. The filter compares -//! those stored bits through an unsigned type of the same size, without copying -//! the value buffer. A bit pattern is simply the bytes Arrow uses to store a -//! value. Comparing it preserves details such as `0.0` versus `-0.0` and -//! different NaN values. [`BranchlessFilterType`] defines these safe, -//! same-sized mappings and checks their sizes at compile time. -//! -//! The fast path is intentionally limited to short lists: -//! -//! - 16 values for 1-byte types -//! - 8 values for 2-byte types -//! - 32 values for 4-byte types -//! - 16 values for 8-byte types -//! - 4 values for 16-byte types -//! -//! These numbers do not follow one size-based pattern. One- and two-byte -//! values have an especially efficient next step: every possible bit pattern -//! fits in a compact bitmap. For a longer list, the bitmap filter turns on one -//! bit for each listed value, then checks membership with a direct bit lookup. -//! This becomes a better fit before a 64- or 128-comparison branchless chain -//! would be useful. Wider types have too many possible values for such a -//! bitmap, so their limits are tuned separately. -//! -//! Larger lists use the standard filter strategy, including bitmap filters for -//! one- and two-byte types. -//! -//! # What about nulls? -//! -//! Null list entries are omitted from the comparison chain but counted by the -//! filter. Evaluation first records which values matched, then -//! [`build_result_from_contains`] combines it with input nulls, list nulls, and -//! `NOT IN` to produce the usual SQL null behavior. - -use std::mem::size_of; - -use arrow::array::{Array, ArrayRef, AsArray, BooleanArray, PrimitiveArray}; -use arrow::buffer::{BooleanBuffer, ScalarBuffer}; -use arrow::datatypes::*; -use arrow::util::bit_iterator::BitIndexIterator; -use datafusion_common::{Result, exec_datafusion_err, internal_datafusion_err}; - -use super::result::build_result_from_contains; -use super::static_filter::{StaticFilter, handle_dictionary}; - -pub(super) type BranchlessNative = - <::CompareType as ArrowPrimitiveType>::Native; - -/// Maximum list size for branchless lookup on 1-byte primitives. -/// -/// Sixteen 1-byte values fit in one 128-bit SIMD vector, so this keeps the -/// branchless list small enough for a single vectorized membership check. -const BRANCHLESS_MAX_1B: usize = 16; - -/// Maximum list size for branchless lookup on 2-byte primitives. -/// -/// Eight 2-byte values fit in one 128-bit SIMD vector, so this keeps the -/// branchless list small enough for a single vectorized membership check. -const BRANCHLESS_MAX_2B: usize = 8; - -/// Maximum list size for branchless lookup on 4-byte primitives. -/// -/// Thirty-two 4-byte values keep the inline list at 128 bytes.

Unlike the type-specialized builders in this module (primitive, byte, -//! boolean, ...), [`RowsGroupColumn`] works for *any* data type that arrow's -//! [`RowConverter`] can encode — including nested types such as `Struct`, -//! `List`, `LargeList` and `FixedSizeList`. It stores one group value per row -//! in a single-column [`Rows`] buffer and compares group keys by their encoded -//! bytes. -//! -//! # Why this exists -//! -//! [`GroupValuesColumn`] can only be used when *every* column of the group-by -//! key has a [`GroupColumn`] implementation; otherwise the whole aggregation -//! falls back to the row-wise [`GroupValuesRows`], which is materially slower -//! and heavier for the columns that *would* have qualified for the column-wise -//! fast path. By providing a generic fallback `GroupColumn`, a schema like -//! `GROUP BY int_col, struct_col` keeps `int_col` on its fast native builder -//! and only pays the row-encoding cost on `struct_col`, instead of dragging both -//! columns onto `GroupValuesRows`. -//! -//! # Relationship to hashing -//! -//! This column does not hash anything itself: [`GroupValuesColumn`] hashes the -//! raw input columns via `create_hashes`, which already supports nested types. -//! Equality is decided here by comparing arrow-row bytes. For the two to agree -//! on group identity, values that this column considers equal must hash equal — -//! see the float `-0.0` / `NaN` note on [`RowsGroupColumn`]. -//! -//!

Two-stage hash aggregation is used for regular parallel execution. -//! -//! The input passes through three execution operators to produce the final -//! aggregation result: -//! -//! 1. Partial aggregation reads the input and produces partial states. It -//! aggregates independently within each partition, which usually reduces -//! cardinality before the later shuffle. -//! 2. Hash repartitioning on the group keys sends all partial states for each -//! group to the same output partition for final aggregation. -//! 3.

When a query only needs the best `N` groups, retaining every group in a hash -//! table and sorting them afterward does unnecessary work.

Serialization hooks for [`ExecutionPlan`], mirroring the -//! `try_to_proto`/`try_from_proto` pattern used for `PhysicalExpr`. -//! -//! # Why the indirection -//! -//! An `ExecutionPlan` must be able to (de)serialize its child plans and its -//! child physical expressions recursively. The concrete recursion lives in -//! `datafusion-proto` (it owns the extension codec, the session context and the -//! central converter), but `datafusion-proto` sits *above* `datafusion-physical-plan` -//! in the crate graph. To let a plan drive that recursion without a dependency -//! cycle, this module defines: -//! -//! * [`ExecutionPlanEncodeCtx`] / [`ExecutionPlanDecodeCtx`] — the stable, -//! concrete context types a plan author interacts with. New capabilities can -//! be added here without changing every plan's hook signature. -//! * [`ExecutionPlanEncode`] / [`ExecutionPlanDecode`] — internal dispatch -//! traits, *defined* here but *implemented* in `datafusion-proto`, that the -//! context types delegate to. This is the dependency inversion that keeps the -//! proto types flowing in one direction only. They are `#[doc(hidden)]`: not -//! public API, `pub` only because their implementors live in another crate. -//! -//! `datafusion-physical-plan` depends on the pure prost types in -//! `datafusion-proto-models` (feature `proto`), never on `datafusion-proto`. -//! -//! # Function-carrying plans -//! -//! Plans that reference UD(A/W)Fs (`AggregateExec`, the window execs, …) also -//! ride the hook: the context exposes typed, *bytes-only* function serde — -//! [`encode_udaf`](ExecutionPlanEncodeCtx::encode_udaf) / -//! [`decode_udaf`](ExecutionPlanDecodeCtx::decode_udaf) and the udf/udwf -//! siblings. These take/return `datafusion-expr` types plus `Vec` and never -//! name a proto type, so the `PhysicalExtensionCodec` (which only -//! `datafusion-proto` can name) stays fully encapsulated behind the adapter that -//! backs these traits. The lookup-order policy (payload → codec; else registry → -//! codec fallback) lives once, in that adapter, rather than in every plan. -//! -//! This is possible because `datafusion-physical-plan` sits *above* -//! `datafusion-expr` in the crate graph; the expression-side ctx (in -//! `physical-expr-common`, *below* `datafusion-expr`) cannot do this, which is -//! why `ScalarFunctionExpr` remains special-cased there. -//! -//!

Most -/// systems typically either already have this information cached locally or can -/// batch access to the remote catalog to retrieve multiple schemas and tables -/// in a single network call. -/// -/// Note that [`SchemaProvider::table`] **is** an `async` function in order to -/// simplify implementing simple [`SchemaProvider`]s. For many table formats it -/// is easy to list all available tables but there is additional non trivial -/// access required to read table details (e.g. statistics). -/// -/// The pattern that DataFusion itself uses to plan SQL queries is to walk over -/// the query to find all table references, performing required remote catalog -/// lookups in parallel, storing the results in a cached snapshot, and then plans -/// the query using that snapshot. -/// -/// # Example Catalog Implementations -/// -/// Here are some examples of how to implement custom catalogs: -/// -/// * [`datafusion-cli`]: [`DynamicFileCatalogProvider`] catalog provider -/// that treats files and directories on a filesystem as tables. -/// -/// * The [`catalog.rs`]: a simple directory based catalog. -/// -/// * [delta-rs]: [`UnityCatalogProvider`] implementation that can -/// read from Delta Lake tables -/// -/// [`datafusion-cli`]: https://datafusion.apache.org/user-guide/cli/index.html -/// [`DynamicFileCatalogProvider`]: https://github.com/apache/datafusion/blob/31b9b48b08592b7d293f46e75707aad7dadd7cbc/datafusion-cli/src/catalog.rs#L75 -/// [`catalog.rs`]: https://github.com/apache/datafusion/blob/main/datafusion-examples/examples/data_io/catalog.rs -/// [delta-rs]: https://github.com/delta-io/delta-rs -/// [`UnityCatalogProvider`]: https://github.com/delta-io/delta-rs/blob/951436ecec476ce65b5ed3b58b50fb0846ca7b91/crates/deltalake-core/src/data_catalog/unity/datafusion.rs#L111-L123 -/// -/// [`TableProvider`]: crate::TableProvider -pub trait CatalogProvider: Any + Debug + Sync + Send { - /// Retrieves the list of available schema names in this catalog. - fn schema_names(&self) -> Vec; - - /// Retrieves a specific schema from the catalog by name, provided it exists. - fn schema(&self, name: &str) -> Option>; - - /// Adds a new schema to this catalog. - /// - /// If a schema of the same name existed before, it is replaced in - /// the catalog and returned. - /// - /// By default returns a "Not Implemented" error - fn register_schema( - &self, - name: &str, - schema: Arc, - ) -> Result>> { - // use variables to avoid unused variable warnings - let _ = name; - let _ = schema; - not_impl_err!("Registering new schemas is not supported") - } - - /// Removes a schema from this catalog.

Valid values are: plain, plain_dictionary, rle, bit_packed, delta_binary_packed, delta_length_byte_array, delta_byte_array, rle_dictionary, and byte_stream_split. These values are not case sensitive. If NULL, uses default parquet writer setting datafusion.execution.parquet.force_filter_selections false (reading) Force the use of RowSelections for filter results, when pushdown_filters is enabled. If false, the reader will automatically choose between a RowSelection and a Bitmap based on the number and pattern of selected rows. -datafusion.execution.parquet.max_in_list_size 20 Maximum number of values in an `IN (...)` list for which pruning will occur. Longer lists will not be used to prune files, row groups, or data pages. Higher values help in cases such as filtering on a list of ~25-100 identifiers, but also make the predicate more expensive to evaluate. Set to 0 to disable `IN (...)` list pruning entirely. Defaults to 20. datafusion.execution.parquet.max_predicate_cache_size NULL (reading) The maximum predicate cache size, in bytes. When `pushdown_filters` is enabled, sets the maximum memory used to cache the results of predicate evaluation between filter evaluation and output generation. Decreasing this value will reduce memory usage, but may increase IO and CPU usage. None means use the default parquet reader setting. 0 means no caching. datafusion.execution.parquet.max_row_group_bytes NULL (writing) Target maximum size of each row group in bytes. When set, the writer flushes whenever either this limit or `max_row_group_size` is reached, whichever comes first. Useful for bounding writer memory on wide schemas where a row-count limit can map to very different byte sizes. Matches the behavior of `parquet.block.size` in parquet-mr. If `None` (the default), only the row-count limit applies. Currently only honored when `allow_single_file_parallelism` is `false`; by default the parallel file writer ignores this limit. datafusion.execution.parquet.max_row_group_size 1048576 (writing) Target maximum number of rows in each row group (defaults to 1M rows). Writing larger row groups requires more memory to write, but can get better compression and be faster to read. When `max_row_group_bytes` is also set, the writer flushes a row group when either limit is reached, whichever comes first. @@ -783,7 +781,7 @@ OPTIONS ('format.has_header' 'true'); query TTTT SHOW CREATE TABLE abc;
