Hi Alexis,

Many thanks for the comments, much appreciated.

On the "pluggable persistence" I think there is already some CouchDB
replication of messages already?

I look forward to when we can see message data in RabbitMQ without pulling
off the messages...

Thanks again ;-)

Mnesia only stores the routing tables and config data.

Ah yes :-)

I don't think this is currently supported.

Yes, that is correct.  Messages are journalled to disk for recovery.

One thing that people have asked for is 'pluggable persistence' in
which messages can also be stored in $YOUR_FAVOURITE_DATABASE
