zhijiangW opened a new pull request #13345: URL: https://github.com/apache/flink/pull/13345
## What is the purpose of the change The current `BoundedBlockingSubpartition` in runtime does not support positive flush timeout setting by design based on the current scheduler strategy. So it is nice to check this compatibility during job graph generation and give some helpful messages for guiding users, which can avoid potential concurrent issues in runtime stack. ## Brief change log - Migrate the buffer timeout setter/getter from `StreamConfig` to `StreamEdge` - Add `#checkAndResetBufferTimeout` method in `StreamingJobGraphGenerator` ## Verifying this change Add new `testNormalShuffleModeWithBufferTimeout` and `testConflictShuffleModeWithBufferTimeout` for verifying the effect. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
