> Currently, DataGeneratorSource requires both GeneratorFunction<Long, OUT> and 
> TypeInformation<OUT> to be passed during its construction. Given that the 
> generator function has a fixed API, it should be possible to reliably extract 
> the OUT type automatically for both lambda generator functions and for 
> objects.
