[jira] [Created] (HBASE-21512) Introduce an AsyncClusterConnection and replace the usage of ClusterConnection

Duo Zhang created HBASE-21512:
---------------------------------

             Summary: Introduce an AsyncClusterConnection and replace the usage of ClusterConnection
                 Key: HBASE-21512
                 URL: https://issues.apache.org/jira/browse/HBASE-21512
             Project: HBase
          Issue Type: Umbrella
            Reporter: Duo Zhang
             Fix For: 3.0.0


At least for the RSProcedureDispatcher, with CompletableFuture we do not need to set a delay and use a thread pool any more, which could reduce the resource usage and also the latency.

Once this is done, I think we can remove the ClusterConnection completely, and start to rewrite the old sync client based on the async client, which could reduce the code base a lot for our client.
