Tsz-wo Sze commented on RATIS-1298:
-----------------------------------
A problem of gRpc + ProtoBuf is that, when the log entries are large, large
buffers are allocated inside the gRPC library. We have no control of these
buffers. Therefore, Ratis Streaming probably will improve the performance over
gRpc + ProtoBuf
> Support non-voting members (Listeners/Learners)

> 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.
