--------------------------------
Summary: Adjust the default netty transport option from nio to auto
Key: FLINK-15306
URL: https://issues.apache.org/jira/browse/FLINK-15306
Project: Flink
Issue Type: Improvement
Components: Runtime / Network
Reporter: zhijiang
Assignee: zhijiang
Fix For: 1.11.0
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.
We would further verify the performance effect via micro benchmark if possible.
