Yeah, I think those should work fine. For something like "concat" it should work with both numbers and strings - and it does. In that case, what gets returned to calcite for the table's schema is an Object for that column, and concat will work against any type of object. > I also think taking this choice out of the hands of the flow developer is bad. I don't believe we are taking the choice out of the hands of the flow developer. We're simply saying that if you want to do some sort of numeric-only aggregate function, your schema must indicate that the field is a number. I think this is fair game. The user can, in this case, simply use a schema that indicates that field is numeric. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
