Maryann Xue commented on PHOENIX-1654:
--------------------------------------
I see. It fixes queries that involve client aggregation and have multiple
group-by keys, like "select a, b, count(*) from (select x as a, max(y) as b
from t group by x) as t1" or "select /* +USE_SORT_MERGE_JOIN*/ t1.a, t2.b,
count(*) from t1 join t2 on t1.c = t2.c group by t1.a, t2.b".
> Incorrect group-by keys from ClientAggregatePlan
