Concerning the suggestion about the `MultiStreamStateHandle` - I am not
sure that this can always work. Different physical files may have headers, so
it may be important to recognize them as different chunks of state in the
general case.
> Introduce state management by OperatorID in TaskManager

> Key: FLINK-7213
> URL: https://issues.apache.org/jira/browse/FLINK-7213
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Affects Versions: 1.4.0
> Reporter: Stefan Richter
> Assignee: Stefan Richter
>
> Flink-5892 introduced the job manager / checkpoint coordinator part of
> managing state on the operator level instead of the task level by introducing
> explicit operator_id -> state mappings. However, this explicit mapping was
> not introduced in the task manager side, so the explicit mapping is still
> converted into a mapping that suits the implicit operator chain order.
> We should also introduce explicit operator ids to state management on the
> task manager.
