- The first proposition was to overload all stateless methods to accept an instance of Described class. However this solution was resulting in modiying a large percentage of the existing KStream and KTable methods.
- The second proposition was to add new methods KStreams#as(Described) and KTable#as(Described) while Described class would be used to customized the named of operation defined previously in the stream. However not only this new method was not conservative with the existing APIs but it also introduce some complexities for methods returning Void.
