Maryann Xue commented on PHOENIX-1580:
--------------------------------------
One minor change to the explain plan maybe, [~ayingshu]. Instead of "CLIENT ...
SORTED BY ...", "CLIENT MERGE SORT" might be better and shows that the order by
has actually been done for individual sub-selects, and the client is just doing
a merge.
> Support UNION ALL
