[rabbitmq-discuss] Job Server Resource Allocation Help

[Alexis Richardson]

Bryan

I assume each job should be completed at most once.

You can achieve something almost like what you want by creating two
queues.  Use one for "paying" and one for "non-paying" jobs by binding
each queue to the (direct) exchange using the keys "paying" and
"nonpaying" respectively.  Assign N servers to the "paying" queue.
Let the remainder consume from both queues using some selection scheme
(eg worker randomly chooses a queue each time a new job is needed).

Many other schemes are possible.  However trying to achieve some total
order (eg 'first come first serve') may be more complex than you
really need.
