@@MikesTechCorner One question though when we a retrying for a message, the thread that was responsible for message processing would be blocked and will not be able to any other tasks right?

[@MikesTechCorner]

@@rahuldeepattri9244 You can route the failed messages to a timeout queue or use the backoff plugin

[@rahuldeepattri9244]

@@MikesTechCorner Thanks for your response! Agreed then spring retry mechanism on timeout queue makes more sense. And the back off plugin you mentioned is a rabbit mq plugin?

[@dimitrihautot3093]

Hi Mike, isn't a missing @EnableRetry the cause of the programmatic approach failure?

[@MikesTechCorner]

I would setup a special queue for retries and then a timeout to wait for a system to come up again. Maybe a delay of 15 min or so.

[@sumedhabhatkar9718]

How did you applied retry mechanism? please tell how you implemented at end

[@MikesTechCorner]

Try to clone the project and look in the code. I have uploaded the project and added link in the description.

Hi how can I acknowledge a message on my listener and where can I see that my message is being acknowledge from. Appreciate if you could help me out!

[@MikesTechCorner]

I'm not in RabbitMQ mode right now... I might dig into again at some point though... In other words I don't know :)

[@naoko1927]

Can the dead letter messages in the dead letter queue requeue back to the origian queue ?

[@MikesTechCorner]

Yes easily. Setup a timeout

[@MikesTechCorner]

Or manually "shovel" the messages to the original queue.

[@naoko1927]

@@MikesTechCorner I setup time to live to the dead letter queue but it doesn't work

[@naoko1927]

@@MikesTechCorner So I have to bind dead letter queue to another exchange and bind that exchange to original queue, but I don't know whether it is a good way

[@MikesTechCorner]

@@naoko1927 Or you setup a timeout on the dlq and another dlq exchange which could be the original exchange
