EclipseLink is assumed here, but any JPA 2. In this chapter we'll focus on publish-subscribe and extend ZeroMQ's core pub-sub pattern with higher-level patterns for performance, reliability, state distribution, and monitoring. Even more importantly, broker has to process 6 messages (each message has to be passed in and out of the broker, thus 12 network hops) which is not much by itself, however, with high transaction rate (say 100,000 business transactions a second) the number of messages processed in the broker may hit the limit of the broker and/or hardware it is running on (600,000 messages a second). The core of "0MQ is just sockets" argument is that it doesn't do the main reason while MQ systems are used instead of, say, sockets - persistence and guaranteed delivery if some endpoints die. Date: Mon, 09/22/2014 JBoss A-MQ is a high performance open source messaging platform based on Apache ActiveMQ.
