I would like to take advantage of the message group feature in ActiveMQ 5.1. After reading the page (http://activemq.apache.org/message-groups.html), I have a question.
Is the message group feature for multiple consumers on the same queue/topic? What I mean is that in the example, there are consumers interested in stocks (IBM,MSFT, SUNW..etc). Are these consumers all subscribed to the same topic/queue or different topics/queues? Assuming that these consumers all subscribe to the same topic/queue, are there any implications with creating hundreds (or thousands) or message groups? Thanks.
