RabbitMQ ack on pub/sub

Question

RabbitMQ 3.6.x

I have a fanout exchange with 2 queues registered. All works fine.

But silly question in pub/sub fanout model, can/should the consumer do acknowledgements?

Answer 1

consumers always have to acknowledgement messages!

Maybe the question is auto_ack yes or not.

But silly question in pub/sub fanout model, can/should the consumer do acknowledgements?

Even if pub/sub usually implements auto-delete, exclusive queues with auto_ack = true , there is not a specific rule !

it depends from your application! :)
