[rabbitmq-discuss] Sematics of ACK/REQUEUE/DISCARD on a message

Using RabbitMQ together with the Carrot Python bindings.

Two questions:

- - assuming a consumer could process a message with success - what is
  the difference in the message handling inside the queue between
  acknowledging it or discarding it - it will be removed from the queue
  in both cases?!

- - assuming a consumer could not process a message properly (e.g. some
  database backend down) and is interested to re-try this message later.
  In this case I would requeue the message. At which position in the
  queue will the message be inserted? At the end of the queue?
