Description
Tony Jordan opened INT-2208 and commented
Splitters (for example) should be able to trigger the creation of a MessageGroup with a given correlationID. This would allow the action of splitting to prompt a the creation of a new MessageGroup in a specified MessageStore. An aggregator downstream using that MessageStore would "expect" messages and timeouts on that group would begin. If no messages ever arrive, the reaper will still expire the group after the timeout and a workflow could handle the situation as needed.
