             Summary: Allow RPC endpoints to use dedicated thread pools
                 Key: SPARK-29398
                 URL: https://issues.apache.org/jira/browse/SPARK-29398
             Project: Spark
          Issue Type: Sub-task
          Components: Spark Core
    Affects Versions: 3.0.0
            Reporter: Marcelo Masiero Vanzin


This is a new feature of the RPC framework so that we can isolate RPC message 
delivery for plugins from normal Spark RPC needs. This minimizes the impact 
that plugins can have on normal RPC communication - they'll still fight for 
CPU, but they wouldn't block the dispatcher threads used by existing Spark RPC 
endpoints.

See parent bug for further details.
