My argumentation above was that this exposes the fact that line 4 is not actually executing `sum(lineitem.l_extendedprice * 1 - lineitem.l_discount)`, that's the logical view of things. Instead `sum(__common_expr_1)` is being computed and `__common_expr_1` is calculated in line 7. For the physical plan I don't think you would want to obscure this. The `Some(1)` bit is unfortunate indeed, but I think that's a separate issue. The physical explain output doesn't format literals as nicely as the logical plan output does. -- This is an automated message from the Apache Git Service.
