Documentation <>
Refers to CheckpointedRestoring interface.
Which jar defines this interface - can’t find it

Also documentation refers to MapState<UK, UV>. Do you have any example of creation of Map State.
For value State in Scala, I can do just do
private var sum: ValueState[(Long, Long)] = _
But it does not work for MapState -
Error:(44, 53) unbound placeholder parameter
  private val newModels : MapState[String, Model] = _
