Dian Fu commented on FLINK-18201:
---------------------------------
[~nicholasjiang] Regarding to the implementation of the Python create_function,
I think it's not necessary to based on Java APIs such as `void
createFunction(String path, UserDefinedFunction userDefinedFunction)` as we
need only persist the full path of the Python function to the catalog.
> Support create_function in Python Table API

> There is an interface *createFunction* in the Java *TableEnvironment*. It's
> used to register a Java UserDefinedFunction class as a catalog function. We
> should align the Python Table API with Java and add such an interface in the
> Python *TableEnvironment*.
