> 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.
