[rabbitmq-discuss] How can I connect in a cluster using Java library

Thu Mar 17 14:54:18 GMT 2011

Is there other way to do this?

The guys here complain the DRBD mode.

Suppose that I decide to not use DRBD and Pacemaker to do replication
of messages. What will be the improvements that I win when using
RabbitMQ Clusters?

Actually, I'll need HA, not scalability. I guess that I dont need a
cluster, right?
