@zbentley The pre-fetching is tied to the `receive()` calls and not the acknowledgements. As long as you keep calling receive, you are making more space in the queue and the client library will ask for more messages to the broker. In this case, it is expected to be a race for consumer-2 to get the 2nd message prefetched. To have the precise behavior of 1 single message, you need to disable pre-fetching completely, by setting `receiver_queue_size=0`. -- This is an automated message from the Apache Git Service.
