Thank you for your reply.
I mean "relational database" for RDB. It means we might need mysql or oracle or whatever to share persistent data between cluster or fail over pair nodes. From your answer I guess we don't support it. we sacrificed the convenience to gain performance, right?

For the original question: when add a new broker to a running cluster, do we need to copy persistent data from other nodes? I guess no, since for load balance cluster we didn't guarantee exactly same, is it correct?

Another question: For the existing broker in a cluster, if somehow we stopped it for a while, could we just restart it and join in to the cluster directly? we don't need to worry the data divergence between load balance cluster nodes, do we? It could happen even if the node has backup, since in the worst case the backup server could also failed, and we didn't provide facility for re-assigning a backup node with a running node.
