> During profiling saw that the code here in passesKeyRangeFilter in Storefile
> {code}
>   KeyValue smallestScanKeyValue = scan.isReversed() ? KeyValueUtil
>           .createFirstOnRow(scan.getStopRow()) : KeyValueUtil.createFirstOnRow(scan

>           .getStopRow());
> {code}
> This row need not be copied now considering that we have CellComparator.compareRows(Cell, byte[]). 
> We have already refactored the firstKeyKv and lastKeyKV as part of other JIRAs.
