James Taylor commented on PHOENIX-2802:
---------------------------------------
Thanks, [~maryannxue]. I filed PHOENIX-2820 for some follow up work. Any ideas
when you look at the change I made? In theory, this should only impact
aggregate queries.
> Merge sort usually not necessary for ORDERED aggregation

> Try something like the following query:
> {code}
> select pod, count(*) as orgs from organization group by pod order by pod desc;
> {code}
> versus this one:
> {code}
> select pod, count(*) as orgs from organization group by pod order by pod asc;
> {code}
> There may be some missing logic in how we setup the client-side order by in
> this case.
