----------------------------------
Summary: StripeCompactionPolicy should support compacting cold
regions
Key: HBASE-25754
URL: https://issues.apache.org/jira/browse/HBASE-25754
Project: HBase
Issue Type: Improvement
Components: Compaction
Affects Versions: 1.4.13, 2.0.0, 3.0.0-alpha-1
Reporter: Xiaolin Ha
Assignee: Xiaolin Ha
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But cold regions' outdated data need to be cleaned.
