I am trying to understand on the design requirements for using Queue, and could not find this question (with answer).

My understanding: Queue means one-to-one. Thus it would be used in a special case (if not rare, very few cases) when a designer is sure that the message would be intended for only one consumer.

But even in those cases, I may want to use Topic (just to be future safe). The only extra case I would have to do is to make (each) subscription durable. Or, I special situations, I would use bridging / dispatcher mechanism.

Give above, I would always (or in most cases) want to publish to a topic. Subscriber can be either durable topic(s) or dispatched queue(s).

Please let me know what I am missing here or I am missing the original intent?
