             Summary: Limit grpc threads in ReplicationServer
                 Key: HDDS-5537
                 URL: https://issues.apache.org/jira/browse/HDDS-5537
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Sammi Chen

In production cluster,  ReplicationServer on DN has as many as core size grpc-default-worker threads, and unlimited grpc-default-executor threads, which are normally too more than needed. 

It's recommended in grpc official documents to use customized thread pool instead，
