| When a message is received by a subscriber, it is _locked_ (or _leased_) for a queue level configured amount of time (see more on the [Managing Queues] page). This means that only one subscriber receives (and can process) a given message in this amount of time. A message needs to be settled once processed (or if processing fails) to ensure it is either removed from the queue or made available again. This is part of the message control flow. |

What I am trying to say here (and below) is that the time for which the lock is held is configured at queue level, and not for each message.

| 1. `MessageContext.ack()` acknowledges the message, and marks it as successfully processed in the queue system. It will be permanently removed and no other subscriber will ever receive it. | ||
| 2. `MessageContext.nack()` marks the message as not processed, releasing the lock in the queue system. It will be viewable for other subscribers to receive and process. | ||
| 3. `MessageContext.extendLock()` extends the currently owned lock by the queue level configured duration. This can be called as many times as you want, as long as you still own the lock. As long as the lock is extended, the message will not be distributed to any other subscriber by the queue system. |
