Hello Alieh, If you set the logging to a more verbose level, then Flink prints a log msg at every iteration.
If you need the current iteration number inside your code, then you should create your UDF as an AbstractRichFunction, where you can call getIterationRuntimeContext(), which has getSuperstepNumber().
