> Use Kryo for user code object serialization

>
> Currently, Flink uses java serialization for user code objects (UDFs). This
> limits the set of supported types which can be caught in the closure or are
> contained as members in the user code object. Maybe we can add Kryo as a
> second serialization mechanism which is used if the Java serialization fails.
> That way we would support more complex user code objects which finally
> improves the user experience.
