-------------------------------------------
Summary: Remove unnecessary traversing to the first and last keys
in the CellSet
Key: HBASE-18251
URL: https://issues.apache.org/jira/browse/HBASE-18251
Project: HBase
Issue Type: Bug
Reporter: Anastasia Braginsky
The implementation of finding the first and last keys in the CellSet is as
following:
{code}
public Cell first() {
return this.delegatee.get(this.delegatee.firstKey());
}
public Cell last() {
return this.delegatee.get(this.delegatee.lastKey());
}
{code}
Recall we have Cell to Cell mapping, therefore the methods bringing the
first/last key, which allready return Cell. Thus no need to waist time on the
get() method for the same Cell.
Fix: return just the first/lastKey(), should be at least twice more effective.
