[rabbitmq-discuss] mirrored queue cluster

Fri Oct 4 20:29:07 BST 2013

To increase the scalability on the mirrored queues .. I guess the suggestion was to have multiple master (queues) and have a load balancer right ..

Let's say we have 4 nodes ...  
1) Cluster these 4 nodes and define an exchange (xyz) .. 
2) Define mirrored topic (abc) on node 1 and 2 and make node 1 as master and node 2 as slave
3) Define same mirrored topic  (abc) on node 3 and 4 and make node 3 as master and node 4 as slave 
4) define some non -mirrored queues( nbc)  in the cluster
5) from exchange(xyz) route some message to mirrored topics (abc) and some to non mirrored queues/topics (nbc)

Does the above make scenes ..

Also we have topics which we need to mirror ...

Why do you need two clusters?

You can have two sets of queues, some are mirrored, some are not. Then set up routing in a way
that some messages are routed to the mirrored queues and others to non-mirrored queues.

This likely will be much easier to operate than 2 clusters one of which does not offer
redundancy. In addition, you won't have to worry about routing messages to one of the two
clusters.
