RFC: Support Follower Replication
While discussing #135 we determined that supporting replication between two followers, for instance in the same datacenter, to reduce WAN overhead, may be a desirable feature.
This RFC proposes the feature to be added after #135, assuming there will be some structural changes to Raft to support follower to follower communication cleanly.
@overvenus I hear you are looking at this?
