Zili Chen commented on RATIS-1298:
----------------------------------
Hi here! May I ask if there is an example of doing load balance with learners?
Currently, when we {{sendReadOnly}} without specifying the server id, all
requests are sent to the leader server. Perhaps I can do load balance on the
client-side wrapping ratis-client and maintaining group traffic info, but a
real-world example can help users like me to leverage what is implemented here
XD.

> 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.
