      Description

      Many states in keyed streams are organized as key-value pairs. Currently, these states are implemented by storing the entire map into a ValueState or a ListState. The implementation however is very costly because all entries have to be serialized/deserialized when updating a single entry. To improve the efficiency of these states, MapStates are urgently needed.
