A given piece of Flink state is held in a single operator. But that operator can be something like a RichCoFlatmap or a CoProcessFunction, and receive and process inputs from two streams (and you can cascade these if more than two streams are involved).

Your question is very broad, so it's not clear if this approach matches the use case you have in mind.
