> When using schemas there should be no need to require a KV, as any. key or
> keys can be act as the K or a V in a KV. Users can use schemas without the
> need for KV in all cases except for state/timers DoFns, which today require
> that the input have type KV. We would like to eliminate this requirement.
> Users should be able to specify a key field extraction in their ParDo, e.g.
> ParDo.of(...).withKeyFields("user.location.city"));
> Or in the DoFn itself.
