Duplicate Messages (Multiple Consumers?)

[Luiz Eduardo Guida Valmont]

Hi!

Question: is it possible to configure a route so that at any given time 
there is at most one consumer?


I thought of using idempotentConsumers. The expression for the message 
id would be any constant, really. This way, when another consumer tries 
to process the exchange, it'd be discarded.

But this seems like bending the rules more than what I'd like to. Hence 
the question. If there's a way to do a semaphore like step, that'd be 
lovely.


Thanks in advance!
