----------------------------------------------
Summary: StoreFile.passesKeyRangeFilter need not create Cells from
the Scan's start and stop Row
Key: HBASE-14099
URL: https://issues.apache.org/jira/browse/HBASE-14099
Project: HBase
Issue Type: Bug
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
Priority: Minor
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.
