James Taylor updated PHOENIX-1847:
----------------------------------
Summary: Order GROUP BY key to match ORDER BY key if it's a subset of the
expressions (was: Order GROUP BY key to match ORDER BY key if it's a subset or
expressions)
> Order GROUP BY key to match ORDER BY key if it's a subset of the 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.
