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