Lars Hofhansl updated HBASE-9935:
---------------------------------
Priority: Minor (was: Major)
> Slight perf improvement: Avoid KeyValue.getRowLength() at some places
> ---------------------------------------------------------------------
>
> Key: HBASE-9935
> URL: https://issues.apache.org/jira/browse/HBASE-9935
> Project: HBase
> Issue Type: Bug
> Reporter: Lars Hofhansl
> Priority: Minor
>
> Here's an example:
> {code}
> KeyValue.createLastOnRow(
> kv.getBuffer(), kv.getRowOffset(), kv.getRowLength(),
> kv.getBuffer(), kv.getFamilyOffset(), kv.getFamilyLength(),
> kv.getBuffer(), kv.getQualifierOffset(), kv.getQualifierLength());
> {code}
> Looks harmless enough, but that actually recalculates the rowlength 5 times.
> And each time it needs to decode the rowlength again from the bytes of the KV.
