One way would to use the matchmaker which I introduced to solve a similar
problem with the ZeroMQ driver. The matchmaker is a client-side emulation of
bindings/exchanges for mapping topic keys to an array of topic/host pairs.
You would query the matchmaker with a topic (key) and it would return tuples in
the form of:
("topic", broker_ip)
In the ZeroMQ case, the "broker_ip" is always the peer, but with RabbitMQ, this
would be one (or more) of your selected brokers. Generally, you would return
multiple brokers when you're doing fanout messaging.
