@dlg99 >swap order of steps 2 and 3 (mark deleted first, do the rest, unmark on error). In combo with https://github.com/apache/pulsar/pull/19097 this should work good enough. > There is still a chance that a topic creation passed the check before ns deletion started, and completed after the ns is marked deleted. I don't think we can solve it easily, this will require either distributed locking or serialization of ns/topic metadata operations e.g. via global system topic. As you said. the topic still has the chance to go into the race condition. > I don't think we can solve it easily, We don't need to solve the user-created topic but we should make sure to clean up the system topic. -- This is an automated message from the Apache Git Service.
