Do the JMX counters for the queues that make up the composite topics increment as expected?
I've never used composite topics so I've got no direct experience, but I would expect the internal consumers to show up in JMX and the counters for both the topics and the consumers to increase, consistent with the behavior of non-composite topics. Would you be willing to create a feature request in JIRA asking for that to be added?
