      Description

      Currently it is not possible to union a stream with itself or a product of itself.
      For example, the following code
      stream.union(stream.map(...))
      fails with this exception: "A DataStream cannot be unioned with itself".
      The documentation currently states that "If you union a data stream with itself you will still only get each element once." and should also be updated.
