Thank you for the detailed test! But I have a few questions. 1. Why add an extra "SUM" outside? 2. I think it’s better for "CAST" not to involve expression calculations. 3. It seems the third case is a low-cardinality test — could you show a high-cardinality scenario? -- This is an automated message from the Apache Git Service.
