Understanding message Finish and Requeue

[lathif....@gmail.com]

Hi all

I just want to ask a simple question. What will happen if a consumer try to requeue an already finished message? Will it get requeued? Or is it an invalid operation?

Since nsq deliver message at least once, I think this is a possible case. Lets say there is a slow consumer that got the message. The NSQD requeued the message, because of timeout. A fast consumer consume the message and finish it. Then the slow consumer tries to requeue the message.

Thanks

After nsqd times-out the message sent to the slow consumer, neither finish nor requeue from the slow consumer have any effect, they just get an error response from nsqd.
