> Messages that target all current members are sent as multicast messages.
> However, these retransmissions can be replayed on new nodes that have just joined the cluster.
> This can result for example in execution of already completed transaction on the new node, causing possible data inconsistency for those entries which are owned by the new node in backup way - the replayed transaction sequence authoritatively overwrites them.
> The node should remember the first topologyId it has seen and do not execute any commands that have lower topologyId.
