> Ratis and EC MisReplication and handled in separate classes, but they share a common parent class MisReplicationHandler. In it, there is logic to create the replication commands (createReplicateCommands() ), where it gets a list of replicas to be copied and new targets.
> For EC, you must copy a specific replica index from A to B, but for Ratis, all replicas are the same. When you have load limiting in place, we really want to copy from the least loaded source. It probably makes sense to split Ratis handling from EC handling here, as they are quite different.
