Hello Martyn, thank you for your answer. It was helpful.
Yes, what you described is what I want to achieve ... but the cluster should not run within the JVM it should be spread around different locations worldwide. So basically what I want to do in the cluster is what I read in one of your links: *Apache ActiveMQ Artemis cluster connections can be configured to only distribute to other nodes if they have matching consumers.* And to this cluster I would like to connect the satellite brokers.
