Documentation https://ci.apache.org/projects/flink/flink-docs-release-1.6/dev/stream/state/state.html#using-managed-keyed-state lists ValueState<T> and List<T>, but their semantics seems to be different. In my tests ValueState<T> is associated with key, but it is not clear to me what List<T> is associated it.

I tried to test List[String] and ValueState[ModelBuffer[String]] and they behave very differently. Can you, please clarify the differences and usage patterns?
