wsry opened a new pull request #11155: [FLINK-14818] Fix receiving InputGate setup of StreamNetworkBenchmarkEnvironment. URL: https://github.com/apache/flink/pull/11155 ## What is the purpose of the change In network benchmark (for example 1000 channels benchmark with 4 record writers) StreamNetworkBenchmarkEnvironment#createInputGate creates 1000 input gates with 4 input channels each, which doesn't make much sense. It is expected that either having 4 receivers with single input gate with 1000 channels each, or a single receiver with 4 input gates, with 1000 channels each. ## Brief change log - The receiving InputGate setup logic of StreamNetworkBenchmarkEnvironment is changed ## Verifying this change This change is already covered by existing tests, such as StreamNetworkThroughputBenchmarkTest. ## 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?
