[erlang-questions] Replicated messaging in Erlang?

[Tim Watson]

Adam, please take some time to walk through the rabbitmq documentation - there's quite a lot of it! Rabbit supports replication using HA (master/slave mirror) queues, or federation for replicating over the WAN/Internet. This does exactly what you've asked for.

If you'd like to understand how it works, take a lot at gm.erl (guaranteed multicast) which is a fully asynchronous ring protocol developed independently at rabbit to support HA.

Cheers.
Tim
