Hi All,
According to the document, normally a listener of a publish/subscribe
kind of exchange can only receive messages after it begins running. Is
there any way to let the listeners receive all the messages ever sent by
producer?
Basically what I need is to have multiple listeners subscribe to the
same queue and each receive exact the same messages sent by the
producer. It does seem to be possible using QPID.
You can have your subscribers browse rather than consume from the
queue. That way messages are never removed from the queue and are
still available to new subscribers. Of course the queue will grow
without limit but I gather that's what you want.
What advantages does this have over using a separate queue for each
user, and a fanout exchange?
