> I think your proposed solution is? Yes that is what I was thinking > I was hoping to use the result of return_type_from_exprs(self, &[Expr], &dyn ExprSchema, &[DataType]) (in invoke) since I call expr.data_type_and_nullable(schema)? on the inputs to get the correct nullability. Ah, I see -- the nullability isn't available from the DataTypes. Most functions don't use the schema nullability to see if they can use a separate fast path but instead use the actual null counts ont he arrays (e.g `Array::null_count` https://docs.rs/arrow/latest/arrow/array/trait.Array.html#method.null_count) I wonder if that would work for your usecase? -- This is an automated message from the Apache Git Service.
