Zakelly opened a new pull request, #24678: URL: https://github.com/apache/flink/pull/24678
## What is the purpose of the change This is a simple PR that wire the new introduced operators of DataStream V2 with the `AbstractAsyncStateStreamOperator`. ## Brief change log - Introduce `AbstractAsyncStateUdfStreamOperator` that is nearly identical with `AbstractUdfStreamOperator`, but extends from `AbstractAsyncStateStreamOperator` - Replace base class of `ProcessOperator` (v2) from `AbstractUdfStreamOperator` to `AbstractAsyncStateUdfStreamOperator`. ## Verifying this change This change is a trivial rework without any test coverage. More will be added when the whole state processing works. ## 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? no - If yes, how is the feature documented? not applicable -- This is an automated message from the Apache Git Service.
