Sebastien, For my part, I don't do *any of it*. I'm the author of the ZeroMQ implementation, where this is a non-issue.
I think that having the Rabbit queues decoupled makes a lot of sense, especially since the code to do this can be generalized across multiple RPC implementations. (i.e. this would be a win for Qpid as well) I'm clearly not a die-hard RabbitMQ admin -- is there a reason to use clustering over a decoupled solution for a greenfield application? -- Eric Windisch On Friday, May 25, 2012 at 17:54 PM, Sébastien Han wrote: > Why don't you use the RabbitMQ builtin cluster solution? > I setup an active/active cluster with the buildin mecanism and put an HAProxy > on top with a priority on a specific node.
