> While transforming values via {{KStream.transformValues}} and
> {{ValueTransformer}}, the key associated with the value may be needed, even
> if it is not changed. For instance, it may be used to access stores.
> As of now, the key is not available within these methods and interfaces,
> leading to the use of {{KStream.transform}} and {{Transformer}}, and the
> unnecessary creation of new {{KeyValue}} objects.
