             Summary: Make streaming write SYNC configurable
                 Key: HDDS-14194
                 URL: https://issues.apache.org/jira/browse/HDDS-14194
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Ivan Andika
            Assignee: Ivan Andika


See BlockDataStreamOutput#needSync, currently SYNC is never used.
{code:java}
private boolean needSync(long position) {
  if (SYNC_SIZE > 0) {
    // TODO: or position >= fileLength
    if (position - syncPosition >= SYNC_SIZE) {
      syncPosition = position;
      return true;
    }
  }
  return false;
} {code}
We can create a configuration to allow SYNC, which is disabled by default to 
preserve compatibility.
