> Currently in CALCITE-482, hints are only supported for Project, Join and
> TableScan. It's also necessary to support hints for Aggregate so as to enable
> fine grained Aggregate configuration, e.g., two-stage-aggregation.
> SELECT /*+ TWO_STAGE_AGG(true) */
> dep_id,
> grade,
> avg(annual_salary),
> min(annual_salary),
> max(annual_salary)
> FROM T
> GROUP BY dep_id, grade;
