-------------------------------------
Summary: Order GROUP BY key to match ORDER BY key if it's a subset
or expressions
Key: PHOENIX-1847
URL: https://issues.apache.org/jira/browse/PHOENIX-1847
Project: Phoenix
Issue Type: Improvement
Reporter: James Taylor
An ORDER BY for an aggregate query is executed on the client-side. We can
optimize the ORDER BY out if the GROUP BY expressions are a subset of the ORDER
BY expressions (taking into account ASC/DESC and NULL FIRST/LAST). We'd need to
do a pass to re-order the GROUP BY based on the ORDER BY, since the GROUP BY is
compiled first.
