                 Key: DRILL-8132
                 URL: https://issues.apache.org/jira/browse/DRILL-8132
             Project: Apache Drill
          Issue Type: Improvement
          Components: Execution - RPC
            Reporter: wtf


# 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, as it can improve 
performance if the number is power of two based on 
PowerOfTwoEventExecutorChooser of Netty.
