rkhachatryan opened a new pull request #19311: URL: https://github.com/apache/flink/pull/19311
## What is the purpose of the change ``` CopyOnWriteStateMap copies the entry before returning it to the client for update. This also updates its state and entry versions. However, if the entry is NOT used by any snapshots, the versions will stay the same despite that state is going to be updated. With incremental checkpoints, this causes such updated version to be ignored in the next snapshot. This change bumps the state version in this case (entry version stays the same). ``` ## Verifying this change Multiple IT cases in https://github.com/rkhachatryan/flink/tree/flip-151-full, e.g. - `ProcessingTimeWindowCheckpointingITCase.testAggregatingTumblingProcessingTimeWindow - `EventTimeWindowCheckpointingITCase.testSlidingTimeWindow` - `AggregateITCase.testWindowWithUnboundedAgg` ## 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/Mesos, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? no -- This is an automated message from the Apache Git Service.
