zhijiangW opened a new pull request #8529: [FLINK-12603][network] Refactor InputGate interface to remove unnecessary methods URL: https://github.com/apache/flink/pull/8529 ## What is the purpose of the change *In order to make abstract `InputGate` simple for extending new implementations in shuffle service architecture, we could remove unnecessary methods from it.* *Currently `InputGate#getOwningTaskName` is only used for debugging log in `BarrierBuffer` and `StreamInputProcessor`. This task name could be got from `Environment#getTaskInfo` and then be passed into the constructor of `BarrierBuffer/StreamInputProcessor` for use.* *`InputGate#getPageSize` is only used for `BarrierBuffer` constructor. We could remove this method and the page size could also be got form task manager configuration instead.* ## Brief change log - *Add the full task name in the `TaskInfo`* - *Remove `getOwningTaskName` and `getPageSize` from `InputGate` abstract methods* - *Refactor the related process to get task name and page size for `BarrierBuffer` and `StreamInputProcessor`* ## Verifying this change covered by existing tests. ## 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, 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?
