… to be cleared Regardless of whether the tablet is submitted for compaction or not, we need to call 'reset_compaction' to clean up the base_compaction or cumulative_compaction objects in the tablet, because these two objects store the tablet's own shared_ptr. If it is not cleaned up, the reference count of the tablet will always be greater than 1, thus cannot be collected by the garbage collector. (TabletManager::start_trash_sweep) This bug is introduced from apache#4891

Proposed changes
Regardless of whether the tablet is submitted for compaction or not,
we need to call 'reset_compaction' to clean up the base_compaction or cumulative_compaction objects
in the tablet, because these two objects store the tablet's own shared_ptr.
If it is not cleaned up, the reference count of the tablet will always be greater than 1,
thus cannot be collected by the garbage collector. (TabletManager::start_trash_sweep)
