> avoid a key copy in TimeSettingIterator
> ---------------------------------------
>
> Key: ACCUMULO-4037
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4037
> Project: Accumulo
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.7.0
> Reporter: Adam Fuchs
> Assignee: Josh Elser
> Priority: Minor
> Labels: performance
>
> In org.apache.accumulo.core.iterators.system.TimeSettingIterator we make a
> copy of the key before setting the time. Seems like this is a completely
> superfluous copy, and we should avoid it. In the current code we do the
> following:
> {code}
> @Override
> public Key getTopKey() {
> Key key = new Key(source.getTopKey());
> key.setTimestamp(time);
> return key;
> }
> {code}
> Instead we should do this:
> {code}
> @Override
> public Key getTopKey() {
> Key key = source.getTopKey();
> key.setTimestamp(time);
> return key;
> }
> {code}
