When cleaner will move unacked queue to ready queue?

[huanghantao]

If my consumer is handling the delivery, and it will take a long time, is the cleanner going to move the delivery from the unacked queue to the ready queue?

No, the cleaner will not move any unacked deliveries as long as the consumer is still alive. Each consumer has its own heartbeat and the checker always checks the heartbeat and only cleans unacked deliveries of dead consumers.

I understand, thank you!
