Planner thinks scanner can scan directly, don't need merge and can do some pre-aggregation works. 2. But scanner found it's a unqiue key table with seq column which need to merge first. I think we'd fix it in planner? Planner should not set preAggregation as true on a unique table with seq column? -- This is an automated message from the Apache Git Service.
