-----------------------------------------
Summary: Allow client to specify replication level in a request
Key: RATIS-208
URL: https://issues.apache.org/jira/browse/RATIS-208
Project: Ratis
Issue Type: New Feature
Reporter: Tsz Wo Nicholas Sze
Assignee: Tsz Wo Nicholas Sze
In Raft protocol, the leader sends a reply to client once the request is
committed and applied to its state machine. A request is committed when the
leader get a majority of responses from all the members in the raft group.
In some applications, the client may want to wait for all member responses
instead of a majority. For example, the application wants to support reading
even if there is only one machine remaining in the group.
