godfreyhe opened a new pull request #8782: [FLINK-12888] [table-planner-blink] Introduce planner rule to push filter into TableSource URL: https://github.com/apache/flink/pull/8782 ## What is the purpose of the change *Introduce planner rule to push filter into TableSource* ## Brief change log - *The TaskInfo is stored in the blob store on job creation time as a persistent artifact* - *Deployments RPC transmits only the blob storage reference* - *TaskManagers retrieve the TaskInfo from the blob cache* - *Added PushFilterIntoTableSourceScanRule that pushes filter into TableSource* - *Added RexNodeExtractor to extract conjunctive predicates to Expressions* ## Verifying this change This change added tests and can be verified as follows: *(example:)* - *Added integration tests for end-to-end deployment with large payloads (100MB)* - *Extended integration test for recovery after master (JobManager) failure* - *Added test that validates that TaskInfo is transferred only once across recoveries* - *Manually verified the change by running a 4 node cluser with 2 JobManagers and 4 TaskManagers, a stateful streaming program, and killing one JobManager and two TaskManagers during the execution, verifying that recovery happens correctly.* - *Added PushFilterIntoTableSourceScanRuleTest that validates logical plan after PushFilterIntoTableSourceScanRule is applied* - *Added TableSourceTest that validates the physical plan for the filterable table source* - *Added TableSourceITCase that validates the execution result for the filterable table source* ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / no / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
