[rabbitmq-discuss] AMQP ack with multiple subscribers

Thu Oct 15 01:28:57 BST 2009

If I have a queue with multiple subscribers/consumers and it also requires
acks for the messages, what is the resulting behavior?

Will the queue round robin the messages out to the subscribers regardless of
whether the messages have been ack'ed yet or not? Or will the first message
basically stall the delivery of the other messages in the queue until the
first message has been ack'ed?

Thanks!
