@mcritchlow I found the following link explain how it works with priority in ActiveMQ: https://dzone.com/articles/activemq-message-priorities. And this is what we'd set up in ActiveAQ in the past to support priority indexing. Is it what you want to know?

@lsitu - I think so, yes that helps. Thank you! I think my only concern is what's noted on the documentation about the potential con noted in http://activemq.apache.org/how-can-i-support-priority-queues.html Note, this sort of tradeoff can have significant performance implications, so you must test your scenarios thoroughly

I suppose we'll just have to keep an eye on things and make sure this doesn't introduce any regressions or seriously slow down normal ingests.
