[rabbitmq-discuss] cluster & HA (not Mirrored Queue Behaviour)

[Michael Klishin]

池凱琳/Kalin Chih:

You do need at least one disk node but performance characteristics of a cluster are highly workload-dependent. If you don't create and remove queues aggressively, disk nodes probably will have the
same performance as RAM nodes (given comparable hardware and OS configuration).

> I hope my cluster provide good reliability & performance. But from my testing result of question 1, the queue eas gone. 

Are you sure the nodes were clustered? Can you provide a script (or several) that I can use to
reproduce your issue?

Thanks,
