dianfu opened a new pull request, #19386: URL: https://github.com/apache/flink/pull/19386
## What is the purpose of the change *This pull request fixes the the state cache clean up logic. The test case test_session_window_late_merge failed when working on PR #19333. After digging into this problem, I found that the reason should be that the logic to determine [whether a key & namespace exists in state cache is wrong](https://github.com/apache/flink/blob/master/flink-python/pyflink/fn_execution/state_impl.py#L1183). It causes the state cache isn't clean up when it becomes invalidate. * ## Verifying this change This change is already covered by existing tests, such as *test_session_window_late_merge*. ## 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, Kubernetes/Yarn, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
