[rabbitmq-discuss] a question about pushing the message to the queue , thank you all a lot

[Alvaro Videla]

Hi,

I think the easiest would be to implement some kind of RPC logic so when
the consumer gets the "banana" message, it can publish a message back to
the sender so the sender can restart the sequence.

You could also try something with basic.nack and a bascic.qos of the number
of messages that you want to cycle through. So in your case you can set a
prefetch count of 3 and whenever you get the banana message you basick.nack
all three. See http://www.rabbitmq.com/nack.html

The first approach could be more flexible.

Regards,

Alvaro
