BewareMyPower opened a new pull request, #24554: URL: https://github.com/apache/pulsar/pull/24554
### Motivation https://github.com/apache/pulsar/pull/22206 misses handling the auto partitions update feature. By default, a producer or consumer schedules a periodical task to query the partition metadata via the old `PulsarClient#getPartitionsForTopic` API, which will trigger the partitioned topic auto creation. This issue does not exist when `allowAutoTopicCreationType` is `non-partitioned` (default) because the number of partitions is 0 for non-partitioned topics, while - Producer does not support partitions shrinking - Consumer will ignore querying partition metadata of non-partitioned topics after https://github.com/apache/pulsar/pull/10708 ### Modifications - Use the new `getPartitionsForTopic` overload introduced in PIP-344 to disable topic auto creation in the auto partitions update task - Add `testPartitionsNotCreatedAfterDeletion` to verify the change NOTE: Since it relies on PIP-344, it can only be cherry-picked to branch-4.0. ### Documentation <!-- DO NOT REMOVE THIS SECTION.

GitHub Actions provides separate quota for pull requests that are executed in a forked repository. The tests will be run in the forked repository until all PR review comments have been handled, the tests pass and the PR is approved by a reviewer. --> -- This is an automated message from the Apache Git Service.
