Hej, What is the correct way of initializing a state-full operator that is using a hashmap? modelMapInit.getClass() does not work neither does HashMap.class. Do I have to implement my own TypeInformation class or is there a simpler way?
cheers Martin private OperatorState<HashMap<InputType,MicroModel>> microModelMap; @Override public void open(Configuration parameters) throws Exception { HashMap<InputType,MicroModel> modelMapInit = new HashMap<>(); this.microModelMap = getRuntimeContext().getKeyValueState("microModelMap", modelMapInit.getClass() , modelMapInit); }
