I consider a key feature. I'd be interested to hear if you have
specific requirements for how it works.
What about selective subscriptions e.g. sub-topic matching or wildcard
matching?
This is another interesting question. To the extent that the
subscription selectors can be aggregated into a superset selector, I
think Dispatch could do a pretty good job with this. For more
sophisticated matching (i.e. content-based, etc.) you would probably
want to put a broker into the mix.
One interesting request I've heard is to be able to establish groups of
consumers for a "topic". A message will be delivered to one consumer
within each group. In other words, messages are broadcast to all groups
but are load-balanced within each group.
That is like shared subscriptions in qpidd (but obviously more
distributed).
Yes, this is possible with qpidd by fanning-out to multiple queues (one
per group) and then having the group members all subscribe to the same
queue.
