> We need to add a few Python building blocks such as ScalarFunctionOperation, BigIntCoder, VarcharCoder, etc for Python ScalarFunction execution. ScalarFunctionOperation is subclass of Operation in Beam and BigIntCoder, VarcharCoder, etc are subclasses of Coder in Beam. These classes will be registered into the Beam’s portability framework to make sure they take effects.
> This PR makes sure that a basic end to end Python UDF could be executed.
