Since many of our applications will likely wish to use RabbitMQ for private things like work queues, using separate vhosts is a good idea. This sets up a single vhost to act as a fedmsg replacement (called pubsub) and configures it for high availability.
The HA policy mirrors queues to all nodes in the cluster and enables automatic synchronization with a batch size of 10K messages. Automatic synchronization means that when a new node joins the cluster, all messages from existing nodes are pushed to the new node, blocking queue activity until mirroring is complete.
