Thanks for the explanation, sounds reasonable to me and we do not need to add it now. Just for keeping track  in case we want to add it later, could we keep it as open?

> The KTable.to operator currently does not use a cache. We can add a cache to this operator to deduplicate and reduce data traffic as well. This is to be done after KAFKA-3777.
