> The API proposed in FLIP-440 makes it very easy and intuitive for developers to declare and use value state, including defining a default initial value.
> However, state access in PTF is more complex and not every state entry needs to be read and/or updated. For future optimizations such as lazy deserialization or avoiding no-op serialization, a “supplier-like“ pattern should be promoted for optimal performance.
> This FLIP proposes the introduction of a ValueView that follows the design principles of MapView and ListView and adopts ValueState interfaces from DataStream API.
