[rabbitmq-discuss] Competing Consumers and Transactional Clients Patterns from Enterprise Integration Patterns

Thu Jan 9 15:37:08 GMT 2014

Hi Alvaro,

Thanks for responding back to me.

Really what I'm trying to do is have multiple clients get tasks off of the
queue and have them commit the completion of the task to the queue as a
means of popping it off permanently. By committing on completion, I'm
trying to ensure that if a client crashes halfway through executing a task,
the queue doesn't lose the task.

Does that make sense?

Thanks,
Jon
