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

Thanks Eugene,

> Acks are indeed asynchronous.

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?

Regards,
Iain.
