### Before Creating the Enhancement Request - [X] I have confirmed that this should be classified as an enhancement rather than a bug/feature. ### Summary When the broker runs for an extended period and topics and subscriptions are frequently created and deleted, we notice a significant amount of stats information lingering in memory. This leads to high memory usage and even full garbage collection (FGC). I believe it is necessary to set autoDeleteUnusedStats to true by default, to promptly clean up these unused stats information ### Motivation When the broker runs for an extended period and topics and subscriptions are frequently created and deleted, we notice a significant amount of stats information lingering in memory.
