> URL: https://issues.apache.org/jira/browse/HBASE-26422
> Project: HBase
> Issue Type: Sub-task
> Reporter: Xiaolin Ha
> Assignee: Xiaolin Ha
> Priority: Major
>
> The reference files are those with these patterns, <hfile>.<parentEncRegion>
> and <table>=<region>-<hfile>.<parentEncRegion>.
> We can compact these reference files in the first compaction after splitting,
> instead of a major compaction.
> Then when the region only has normal hfiles and HFileLink files, it can be
> splitted once more.
> From the overall perspective, it can reduce compaction IOs.
