fecet opened a new issue, #23058: URL: https://github.com/apache/pulsar/issues/23058
### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Motivation There is a API for increase partitions for a topic https://pulsar.apache.org/admin-rest-api/?version=3.3.0#operation/PersistentTopics_updatePartitionedTopic but it only accept a greater number (as the doc says, it should be **incremental**). I'm wondering if it's possible to decrease a existing partitioned topic, otherwise, I have to copy my topic to a new one and delete it manually. ### Solution _No response_ ### Alternatives _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
