[rabbitmq-discuss] Acked Message getting redelivered

Yes but this is hard when messages are consumed by a cluster, they would have to share a single store to track processed messages or use a local store and ensure that certain messages are only processed by specific hosts in the cluster.

As far as my experience goes it's correct, you have to implement it at a higher level.

Thanks Eugene,

So this means that the only reliable way to implement "at most once delivery" is to remember the messages uuids that you have processed, which won't work for clustered consumers.  Is this correct or is there another way to achieve this?

Iain.
