Moran updated HBASE-25754:
--------------------------
Description:
Cold regions cannot perform compactions by flushing memstores, while
CompactionChecker can period check need compaction regions.
But some cold regions using stripe store engine may not be checked to perform
compaction by`needCompaction()` or trigger automatic major compactions, because
StripeCompactionPolicy#shouldPerformMajorCompaction() always returns false.
StripeCompactionPolicy never performs automatic major compactions now.
But cold regions' outdated data need to be cleaned.
