> Is there any reason why we not use the `BuiltInScalarFunction` to implement this new function? From my point of view, it would be much simpler if we use `BuiltInScalarFunction` because it doesn't need to refactor the codegen logic. The reason is that the scalar function can not resolv the function name `CURRENT_ROW_TIMESTAMP`, it always use the function name `CURRENT_ROW_TIMESTAMP()`, I think what we want is aligned with `CURRENT_TIMESTAMP` -- This is an automated message from the Apache Git Service.
