> Affects Versions: 1.0.0
> Reporter: Aljoscha Krettek

>
> Currently, we only allow partitioned state when both inputs are keyed (with
> the same key type). I think a valid use case is to have only one side keyed
> and have the other side broadcast to publish some updates that are relevant
> for all keys.
> When relaxing the requirement to have only one side keyed we must still
> ensure that the same key is used if both sides are keyed.
