zhijiangW opened a new pull request #10662: [FLINK-15306][network] Adjust the default netty transport option from nio to auto URL: https://github.com/apache/flink/pull/10662 ## What is the purpose of the change *The default option of `taskmanager.network.netty.transport` in `NettyShuffleEnvironmentOptions` is `nio` now. As we know, the `epoll` mode can get better performance, less GC and have more advanced features which are only available on linux. Therefore it is better to adjust the default option to `auto` instead, and then the framework would automatically choose the proper mode based on the platform.* ## Brief change log - *Modify the default option value for `NettyShuffleEnvironmentOptions#taskmanager.network.netty.transport`* - *Re-generates the related html files* ## Verifying this change via micro-benchmark ## 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?
