> PythonScalarFunctionOperator is a standalone StreamOperator and it doesn’t need to how the Python ScalarFunctions are executed which is the responsibility of PythonScalarFunctionRunner:
>  # It is a StreamOperator which employs PythonScalarFunctionRunner for Python ScalarFunction execution
>  # It sends input elements to PythonScalarFunctionRunner, fetches the execution results, constructs the result rows and sends them to the downstream operator
>  # It should handle the checkpoint and watermark properly
