[rabbitmq-discuss] one exchange and different nodes

[chen-hongqin]

Thanks, Simon.
If I want two non-mirrored queues and each of them is in different nodes, I can create two connections and declare them separately, is that right? Or does have any other convenient way to do this work in the cluster?

I'm not sure I understand your question, but: 

* Exchanges live on all nodes by definition 
* Non-mirrored queues live on the node on which they were first declared 
* Mirrored queues live on whichever nodes their mirroring policy implies 
* Therefore declaring two non-mirrored queues on the same channel will  
put them on the same node
