Zakelly opened a new pull request, #25367: URL: https://github.com/apache/flink/pull/25367
## What is the purpose of the change After [FLINK-36117](https://issues.apache.org/jira/browse/FLINK-36117), we port old state backends implementation to new api using AsyncKeyedStateBackendAdaptor, but it cannot work because the KeyContext is not properly handled. This PR fixes this. ## Brief change log - Add a listener for state context switch, make all `AsyncKeyedStateBackend` implement it. - For `AsyncKeyedStateBackendAdaptor`, set current key when a context switched. ## Verifying this change This change is without any test coverage, since it is difficult to be covered by a UT. ## 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): yes - 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? no - If yes, how is the feature documented? not applicable -- This is an automated message from the Apache Git Service.
