ifndef-SleePy opened a new pull request #9298: [FLINK-13491][datastream] AsyncWaitOperator supports BoundedOneInput URL: https://github.com/apache/flink/pull/9298 ## What is the purpose of the change * `AsyncWaitOperator` should respect semantics of `BoundedOneInput` ## Brief change log * `AsyncWaitOperator` supports `BoundedOneInput` * Wait the in-flight inputs in `AsyncWaitOperator`.`endInput` * I keep this waiting operation a bit redundant both in `endInput` and `close` because we probably re-think the `endInput` semantics in the near future * BTW, I think the resource releasing of `AsyncWaitOperator`(endInput/close/dispose) is a bit messy. However I would like to discuss it in another thread. ## Verifying this change * This change added tests in `AsyncWaitOperatorTest` ## 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, 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? not applicable
