Thanks for the answer, but I set brokerDeleteInactivePartitionedTopicMetadataEnabled and then restarted pulsar but it doesn't seem to work.Ten minutes after restarting, I could still get the topic without subscribers from the interface.

There's a limitation in the deleting inactive topics when it comes to completely unused topics. If the namespace bundle of the topic isn't active, the topics won't get deleted.
