@goldmedal If we move the expression expansion to analyzer as the comment said, I guess you can still tell the different from `SELECT * FROM A and SELECT c1, c2, c3 FROM A`. I think expand expression in builder is quite early, if there are 1000 columns, we need to carry those columns around in many places. It is better to delay expansion *lazily* as long as possible. -- This is an automated message from the Apache Git Service.
