[rabbitmq-discuss] Custom storage backends for queues (MySQL)

[Christian Legnitto]

Would this just store undelivered messages (I think that's what's in the mnesia db currently) or would it be a store of all messages that have entered Rabbit (more like a historical message cache)? I'm interested in the latter, preferably with Riak.

Now that I think about it, probably wouldn't be too hard to write a rabbit plugin that ships all messages from all exchanges over to Riak using the Riak erlang lib. Does something like that already exist?

Thanks,
Christian
