I have a consumer which produces events and a number of different subscribers who are interested in processing this event. The subscribers are load balanced so there are N machines running the same subscriber, but I want this group to process a message only once.
I looked at ActiveMQ Virtual Topics but that allows me to load balance only one set/group of subscribers at the end of a topic. What I need, is to be able to load balance multiple groups/set of subscribers at the end of a topic. For example, if I am an alarm dispatch center, I may have a single producer which puts an ALARM message on to a topic and multiple consumers that are going to receive this message. One consumer can send an e-mail, another consumer could contact police/emergency services, yet another consumer can make a phone call to the subscriber. Each one of these consumers may be represented by N number of physical servers for scalability and load balancing. Each one of these consumers needs to get and process the message exactly once. So, I need something like a Virtual Topic Group concept? Is there a way to accomplish what I want such that every time I add a new consumer type I don't need to create a new topic and put it into a composite topic? Thanks. -AP_ -- View this message in context: http://activemq.2283324.n4.nabble.com/How-to-configure-multiple-load-balanced-subscribers-at-the-end-of-a-topic-tp4226910p4226910.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
