> Invoking to some methods in KeyValue may could be short cut. Like
> KeyComparator.compareColumns -> KeyValue.compareColumns,
> KVComparator.compareColumns -> KeyComparator.compareColumns ->
> KeyValue.compareColumns,
> KeyComparator.compareRows -> Bytes.compareTo,
> KVComparator.matchingRows -> Bytes.equals,
> MetaKeyComparator.compareRowid -> Bytes.compareTo, ... etc.
> Will apply the change, the test the performance difference.
