Hi, In environment configuration when set the time characteristics to ProcessingTime via setStreamTimeCharacteristic(...) call, I cannot see watermarks in the Flink UI. I think this is expected, because watermarks disabled in the source (using Kafka as source)?
Another point here is, can I use Event Time Timers even if I set the time characteristics to ProcessingTime (via ctx.timerService().registerEventTimeTimer(...))? As far as I understood from the documentation, Event Time Timers needs watermarks which sets the operator time, so I wonder if I can use event time timers in case of ProcessingTime selected in the environment? Also when I set the time characteristics to Event Time can I use both processing time timers & event time timers without any problem? Thanks,
