>
> 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 But cold regions' outdated data need to be cleaned.
