> Currently we use SQLUserDefinedType annotation to register UDTs for user classes. However, by doing this, we add Spark dependency to user classes.
> For some user classes, it is unnecessary to add such dependency that will increase deployment difficulty.
> We should provide alternative approach to register UDTs for user classes without SQLUserDefinedType annotation.
