[jira] [Created] (HBASE-14479) Apply the Leader/Followers pattern to RpcServer's Reader

Hiroshi Ikeda created HBASE-14479:
-------------------------------------

             Summary: Apply the Leader/Followers pattern to RpcServer's Reader
                 Key: HBASE-14479
                 URL: https://issues.apache.org/jira/browse/HBASE-14479
             Project: HBase
          Issue Type: Improvement
          Components: IPC/RPC, Performance
            Reporter: Hiroshi Ikeda
            Assignee: Hiroshi Ikeda
            Priority: Minor


{{RpcServer}} uses multiple selectors to read data for load distribution, but the distribution is just done by round-robin. It is uncertain, especially for long run, whether load is equally divided and resources are used without being wasted.

Moreover, multiple selectors may cause excessive context switches which give priority to low latency (while we just add the requests to queues), and it is possible to reduce throughput of the whole server.
