Alexander Fedulov updated FLINK-33286:
--------------------------------------
Description:
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 generator functions passed both as lambda
and as objects.
