Well, the implementation I am out after is a Java Queue that I can plug into an existing API. In the current implementation of the poll method, this delegates to...

Yeah, that's what I am currently thinking would be the best solution. If one wanted to map this into a Java Queue, that would still be possible by a subscriber...

Yeah, that sounds like a better idea as it allows the subscriber to decide on the polling. One issue I found however was mapping back from groupKey to groupId, if...

In a modular application where many modules use Spring Integration but with their own groups, the messages of an abandoned module (version) will stay forever. It would be nice if...

I do not find it so strange, most dedicated message queues offer some form of TTL for messages. And it's not so strange to retire modules of applications that might...
