If you have two clients (producers) targeting two different nodes in a JBM2 cluster config then JBM2 Cluster cashes MessagesID in the “ target Node”; node that distributes messages in a RoundRobin way between itself and the cluster members, the other nodes of the cluster cash MessageID of what they received as well. Is there a way to setup a distributed cash to enable detection of duplicated messages in a cluster config with more than a client targeting different cluster nodes?
