zhijiangW commented on issue #11421: [FLINK-15962][network] Reduce the default chunk size to 4M in netty stack URL: https://github.com/apache/flink/pull/11421#issuecomment-600976185 Thanks for the updates, @gaoyunhaii ! The code is generally good to me. I have only one concern. As we known, the default chunk size in netty is 16MB. If we adjust it to a smaller value, it is better to give some reasons why we consider 4MB, not 1MB or other values as default. Another thought is that it might be possible to integrate another `NettyBufferPool` instance used in queryable state now, not only for the chunk size issue. But it would be a separate ticket future.
