----------------------------------------------------------
Sorry I was a bit busy on last severals days and I am trying to catch up on
your discussion.
Per my understanding, what [~yjxxtd] suggested was already different from the
proposal in this JIRA. [~yjxxtd]'s proposal sounds like a listener that allows
data loss (because sync from a follower).
Can we make a separate JIRA for [~yjxxtd]'s proposal? I believe the original
proposal of listener/learner in this JIRA still make senses.
[~yjxxtd] [~szetszwo] what do you think?

> It's time to add the non-voting member, or leaner that is proposed in Raft
> thesis 4.2.1 (you can find a copy at [1]).
> The leaner is useful to maintain high availability when new servers join Raft
> ring (details at thesis 4.2.1). For Ozone SCM HA effort, we have also
> discussed the possibility to utilize leaner as the tool to replace SCM nodes
> online.
