[jira] [Created] (HDFS-12329) Ozone: Ratis: Readonly calls in XceiverClientRatis should use sendReadOnly

Mukul Kumar Singh created HDFS-12329:
----------------------------------------

             Summary: Ozone: Ratis: Readonly calls in XceiverClientRatis should use sendReadOnly
                 Key: HDFS-12329
                 URL: https://issues.apache.org/jira/browse/HDFS-12329
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
    Affects Versions: HDFS-7240
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh
             Fix For: HDFS-7240


Currently both write and readonly calls in Ratis use RaftClient.send which enqueues the the request to the raft log and is processed later when the log entry is consumed.

Readonly call can be optimized by using RaftClient.sendReadOnly which will directly query the RaftServer for a particular request.

This jira will be used to discuss this issue.
