> Orca removed the distinct expression when it is used on the agg expression even if there is group by clause, do we need to consider that? We can consider that type of optimization in the future. In line with the goals of this PR, we have optimized statements like DISTINCT, DISTINCT ON, ORDER BY, and LIMIT. However, given the presence of GROUP BY, the optimizations for ORDER BY and LIMIT may no longer apply. With GROUP BY clause should be another topic for optimization. -- This is an automated message from the Apache Git Service.
