> While testing the {{DataStream}} API, I noticed that an iterative job with {{maxWaitTimeMillis}} set, sometimes did not terminate depending on the used parallelism. Since I used a bounded source with few events, it looked a bit as if the iteration tasks couldn't terminate if they didn't receive an event. The corresponding testing job including test data can be found [here|https://github.com/tillrohrmann/flink-streaming-batch-execution/tree/iteration-problem].
