[rabbitmq-discuss] Drawbacks and advantages of "autoack" mode?

[Alfonso Pantoja]

Simon,

Sorry, my mistake. I meant "non explicit-
acking" (auto_ack=no_ack=true) instead of "explicit-acking".
So the question is if a queue consumed by a consumer using auto_ack
can contain messages with Delivered flag set to true?

Regards,


Alfonso
