I think this is a very nice idea. Looks good to me.
A minor point I was thinking about was to maybe add the Utils call not in
the DataSet, but directly in the operator since we also didn't specify the name
there before. Is the reason for this the different stack traces for Java and
Scala? In any case, I'm also fine with the current solution.
