URL: https://github.com/apache/drill/pull/2464
> Improvement of RPC
> ------------------
>
> Key: DRILL-8132
> URL: https://issues.apache.org/jira/browse/DRILL-8132
> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - RPC
> Reporter: wtf
> Assignee: wtf
> Priority: Minor
>
> # Separate EventLoopGroup between dataserver and control client/server, as
> the node which is busy on receiving data from different nodes may occupy all
> EventLoopGroup threads, will block the control rpc message, e.g. fragment
> transfer.
> # Change the default threads of EventLoopGroup to 8(current is 10), as it
> can improve performance if the number is power of two based on
> PowerOfTwoEventExecutorChooser of Netty.
