> Project: HBase
> Issue Type: Improvement
> Components: Performance
> Reporter: Zheng Wang
> Assignee: Zheng Wang
> Priority: Major
>
> Currently we use CellComparatorImpl to compare cells, it compare row first,
> then family, then qulifier and so on.
> If the comparing inner the store, the families are always equal(unless the
> familyLength is zero for special purpose), so this step could be skipped for
> better performance.
