[Marc Teichtahl]

You are correct in your last statement

For each message to a topic exchange identify the matching queues and
then round robin between theses.

Sorry, it's not very clear what 'I would like the exchange to round
robin messages to each consumer queue for the "same" topic' means.

Do you mean something like: for each message, evaluate the routing as
a topic exchange normally would, giving a list of queues. But then
rather than routing to all those queues, just route to one, in some
round robin fashion?

Or something else?

Cheers, Simon
