> Key: HBASE-25754
> URL: https://issues.apache.org/jira/browse/HBASE-25754
> Project: HBase
> Issue Type: Improvement
> Components: Compaction
> Affects Versions: 3.0.0-alpha-1, 2.0.0, 1.4.13
> Reporter: Xiaolin Ha
> Assignee: Xiaolin Ha
> Priority: Minor
> Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.3, 2.3.6
>
>
> 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 But cold regions' outdated data need to be cleaned.
