[rabbitmq-discuss] Query on bulk acknowledgement - For both Publisher confirms and Consumer Acknowledgement

[Behnam Behzadi]

That coordination is non-trivial and very error-prone. Any reasons
delivery-tag is not unique per queue? Of course we'd have to pass the
queueName to Channel.basicAck() method in that case. Does AMQP allow such
implementation?

Thanks
Behnam
