> Currently, there are places where Python ScalarFunction could not be used, for example:
>  # Python UDF could not be used in MatchRecognize
>  # Python UDFs could not be used in Join condition which take the columns from both the left table and the right table as inputs
> We should add validation check for places where it’s not supported.
