> 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.
> [~gyfora] Did you try this with what you're working on?
