Hi sweta, State of different keys are isolated with each other. It means, you could read/write the state of current key in `ProcessFunction`/`KeyedProcessFunction`/`ProcessWindowFunction`, there is no possible to read/write state of other keys.
Would you please describe your business demand, let's see if there is other way to satisfy the requirement.
