Sorry for the late reply. I haven't set up the test environment for python yet so I tried a SQL like this and got the expected result. ```SQL SELECT c1 + c2, c1 * c2 from test where c1 > 2; ``` I'll run the python test on local later. But for this case, I'm not sure whether it is related to this change. As `a+b` and `a-b` aren't "common expression". The optimizer should leave the logical plan unchanged. Please correct me if I missed something :D -- This is an automated message from the Apache Git Service.
