kristoffSC opened a new pull request, #21101: URL: https://github.com/apache/flink/pull/21101
## What is the purpose of the change Fixing [FLINK-29627](https://issues.apache.org/jira/browse/FLINK-29627) where recovery more than one Committable causesed `IllegalStateException` and prevents cluster to start. Implemented fix is based on merging committables from same subtaskId during recovery for Sink V2 architecture. ## Brief change log - Enhance `CheckpointSimpleVersionedSerializer::deserialize` by calling `SubtaskCommittableManager::merge` for committables for same subtaskId. ## Verifying this change - Add new test `Committablecollectorserializertest::testCommittablesForSameSubtaskIdV2SerDe` to verify deserialization of multiple committables for the same subtaskId. - Enhanced `CommitterOperatorTest::testStateRestore` to include committables for same subtaskId. ## 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: (**yes**) - 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?
