All - We've been using Qpid 0.5 up to this point in our applications, and we're at the point where we can begin evaluating 0.6. Since it's supposed to be "the future", we've been taking a look at the new messaging API, but we're hung up in one spot - we don't see (or haven't found) a means to acknowledge messages individually and/or out-of-order. Our application is heavily dependent on durable/persistent messages, and while we can guarantee that all messages will be consumed and acknowledged in a timely manner, we can't guarantee that all will be acknowledged strictly in the order in which they were received. Is there, then, a means to acknowledge individual messages, possibly out-of-order?
It is in the python version, where acknowledge takes an optional message argument. It isn't yet in c++, but I have created a Jira for that and will take a look at a solution as soon as I can: https://issues.apache.org/jira/browse/QPID-2807.
