publisher acks for persistent messages
Acknowledgements are sent to the producer in the following cases
(assuming the channel in confirm mode):
- a transient message has been received (i.e. it is ack'd
immediately),
- a basic return has been sent (the ack is sent immediately
afterwards),
- a persistent message has been consumed [by a consumer] or got [via
basic.get] and ack'd by the client (or the retrieval was no-ack),
- a persistent message has been written to disk (both the message
and its index).
At least in theory, every message published on a confirm channel will
at some point be ack'd. A message is only ack'd once and the reason
it was ack'd is hidden.
