URL: https://github.com/apache/flink/pull/9850 ## What is the purpose of the change The purpose of this pr is to add a network benchmark for data skew scenario in which most of the data will go to a few channels. The added benchmark simulates the most extreme scenario in which nearly all data goes to only one channel. ## Brief change log - Add DataSkewStreamNetworkThroughputBenchmark to simulate data skew scenario. - Add DataSkewStreamNetworkThroughputBenchmarkTest to verify the added benchmark. ## Verifying this change A new DataSkewStreamNetworkThroughputBenchmarkTest was added to verify the change. ## 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?
