codelipenghui opened a new issue #5631: Topic auto creation for non-persistent topic. URL: https://github.com/apache/pulsar/issues/5631 **Is your feature request related to a problem? Please describe.** Currently, we can disable the topic auto creation at broker side, but for non-persistent topic, disable topic auto creation isn't works well. Unlike persistent topic, we need to create mledger znode in zookeeper, non-persistent topic only maintained in broker, so must allow topic auto creation for non-persistent topic now. But we also need to disable the non-persistent topic auto creation for topic management. **Describe the solution you'd like** Add support for disable non-persistent topic auto creation. **Describe alternatives you've considered** Since we just need to store the created non-persistent topics, i'd like to use a system topic to store the non-persistent topic create or delete log and the broker cache the non-persistent topics which is belongs to owned bundles.
