ASF GitHub Bot commented on FLINK-5024   Re: Add SimpleStateDescriptor to clarify the concepts GitHub user StephanEwen opened a pull request: https://github.com/apache/flink/pull/3243 FLINK-5024 [core] Refactor the interface of State and StateDescriptor This is a refactored version of #2768 This pull request splits the `StateDescriptor`: Basic `StateDescriptor`: This only contains only the information The `SimpleStateDescriptor` is the base of all currently used states and holds the information about a single serializer, for the state type. This prepares for a future `CompositeStateDescriptor` that would have multiple serializers, such as for the upcoming `MapState`. This is technically not API-breaking, since it only touches methods with `@PublicEvolving` annotations. We should think carefully, though, because this may affect all users that use the state API on `RuntimeContext` and on the `TriggerContext` (in custom windows).
