Hi folks I'm extending a RichFlatMapFunction in order to use states on a keyed stream. Concerning this i have two questions:
1. I have a var state_item: ValueState[Option[String]] as a local variable in this class. Initialized with state_item = getRuntimeContext.getState(new ValueStateDescriptor..... in the open function. Is the field state_item for every key different? In other words if I have a key with val1 and val2 will these get two different states? 2. The open function contains a override def open(conf: Configuration) configuration. Is there a way to input a custom configuration in there? Thanks Simon
