[rabbitmq-discuss] Redelivery to Multiple Consumers

Fri Feb 24 23:29:30 GMT 2012

Hi,

Imagine multiple consumers reading from same queue. It's a fanout exchange so each C is getting a subset of the messages in the queue. In response to a message, C1 starts some long-running task; but C1 does not ACK the message (C1 won't ACK it until the long-running task has finished). Now C1 dies.

As I've learned on this list, after detecting the broken connection between it and C1, the broker will redeliver the consumed yet un-ACKed message.

Is the broker free to redeliver that message to *another* consumer, C2; or will it redeliver only to C1 when it comes back on-line?

Thank you.

-Paul
