Code Review
This pull request updates the TiDB documentation for the v8.5.7 release, introducing several new features and improvements, including LATERAL derived tables syntax parsing, partial indexes, CPU-aware hot Region scheduling, TiCDC table routing, GCP KMS encryption with WIF, and the max_user_connections attribute. It also documents new system variables like performance_schema_session_connect_attrs_size and tidb_enable_batch_query_region, updates default values for auto-analyze concurrency and index merge fix controls, and removes references to the deprecated TiDB Lightning Web Interface. The reviewer's feedback focuses on aligning the text with the style guide by converting passive voice to active voice, addressing the user directly in the second person, correcting capitalization (e.g., 'CPU'), ensuring consistent terminology (e.g., 'logical I/O'), and using the present tense for updated behaviors.
Important
