Subject Re: About Operator and OperatorBase

Thanks for the explanation, Stephan. I always wonder why the extra
common APIs exist.

Then I think this should be high priority if we want to remove the
common API to reduce the unnecessary layer and "dead code". As Ufuk
mentioned before, better doing it now before more stuff build on top
of Flink.

So removing old Record API [1] and the tests depending on them is step
one of the process, but what is JSON API?
