poorbarcode opened a new pull request, #24496: URL: https://github.com/apache/pulsar/pull/24496
### Motivation **Issue**: negative unack-messages - Consumer-1 received messages. - Unload the topic. - The message may be sent to consumer-2, but the consumption of consumer-1 is still in progress now. - Consumer-1 and consumer-2 acknowledge the message concurrently. `unack-messages` may be reduced twice in above scenario, you can reproduce the issue by the new test `testAcknowledgeConcurrently` ### Modifications - Only reduce `unack-messages` who actually deleted messages successfully. - This PR also fixes the issue of the `unack-messages` is not accurate - The current PR does not fix the same issue when enable TXN, we need a separate PR to fix it ### Documentation <!-- DO NOT REMOVE THIS SECTION.
