Hi Community, I am thinking that we can start 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. What do you think? Any objection or concern to not support leaner in Ratis?
