> The goal is to extend the work started in HIVE-14002.
> For instance, given the following query:
> {code:sql}
> explain
> select key, value, count(key + 1) as agg1 from src 
> group by key, value
> order by key, value, agg1 limit 20;
> {code}
> We can push the limit to the GBy operator. However, currently we do not do it.
