JingsongLi opened a new pull request #9796: [FLINK-14253][table-planner-blink] Add hash distribution and sort grouping only when dynamic partition insert URL: https://github.com/apache/flink/pull/9796 ## What is the purpose of the change Now in BatchExecSinkRule, we don't have static partitions, if it is a partitioned table, will add hash distribution and sort grouping. It is wrong: 1. Group only when dynamic partition insert (not all partition fields are static partitions) 2. We can just hash and sort dynamic partition fields instead of all partition fields. ## Verifying this change stream and batch PartitionedSinkTest ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no
