Hi Gerard,

such a type of state is not yet supported, but on the roadmap.
The feature is called Broadcast State. A description is in JIRA [1].

Best, Fabian

> Hello,

> Is it possible to have managed operator state where all the parallel
> operators know that they have the same state? Therefore, it would be only
> snapshotted by one of them and in case of failure (or rescaling) all would
> use that snapshot.

> For the rescaling case I guess I could use union redistribution and just
> keep one of the elements of the list, but given the size of the state it
> would be more efficient if this can be avoided.
