+1 on this direction. Although Streaming Write Pipeline removes the Raft
overhead of the WriteChunk by making the streaming the actual data, there is
still Raft overhead on the data commit (PutBlock). So I think either we support
full Raft Pipeline (i.e. V1) or full streaming (i.e V3).
Just wondering whether this be similar to CRAQ
(https://issues.apache.org/jira/browse/HDDS-12578) and HDFS datastream?
was (Author: JIRAUSER298977):
+1 on this direction.
