Summary: Optimize ORDERED group by
Key: PHOENIX-2818
URL: https://issues.apache.org/jira/browse/PHOENIX-2818
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
Assignee: James Taylor
We currently check each row against the previous row when we execute a GROUP BY
in row key order. We only need to check the previous row at the boundary while
it's the same as the first row(s) in the next scan, kind of a hybrid between
the ConcatResultIterator and the GroupedResultIterator.
