Hi, After following all the instruction for how to manage a states with flink for non-keyed stream and after implementing all the required functions and defining all the variables (listState and the descriptor and so on), the program did actually worked well. But then I had to debug the program and surprisingly I found that these tools are never used. The debugger had never stepped into any of the state-able functions [initializeState() and snapshotState()] and even after I utterly removed all the state’s variables I still managed to use data from previous call and the program ran successfully. So please tell me what all that big stateful API is about?
