Operator state

[Navneeth Krishnan]

Hi All,

Is there a way to share operator state among operators? For example, I have an operator which has union state and the same state data is required in a downstream operator. If not, is there a recommended way to share the state?

Thanks

Hi

When talking about sharing state, broadcast state [1][2] might be a choice.
