> @alamb How is `simplify ` like for array concat operator rewrite? If we have MakeArrayUDF, `args` are for MakeArray only, but we need BinaryExpr that includes two array functions and 1 operator to start the simplification. It seems function level optimizer can only works for simplification like A function to B Expr / function. 🤔 that is a good point that the simplification is needed for `StringConcat` operator 🤔 > simplify for arrow_cast is just trying to do actual casting x as i64 right? Yes Sorry for my delay, I have been out the last few days. I am catching up with reviews -- This is an automated message from the Apache Git Service.
