Hello, I have a stateless Flink job that processes incoming stream as follows:* For a specific key, an event is produced every 10 sec.* Every 60 sec, the event is acted upon (the event is modified, enriched). What is important is the event gets acted upon every 60 second. * Upon job restart, it is ok if the processor ends up modifying an event twice in a 60 second window, as this would be an infrequent occurance. Based on the above requirements, I feel a stateless processor where I keep track of current Processing time when to modify an event would suffice. In Map(), I could use something like "Instans.now()" to get current time. However, that limits my Unit testing, as I am not able to modify the processing time. Is there an option where I can modify the "processing time" for stateles processor? I developed a different stateful processer where KeyedProcessFunction was extended. In that case, the "Context" was passed to the processElement() method, in which I was able to get the current procesing time using the method - ctx.timerService().getCurrentProcessingTime(). I was able to modify the processing time from the test harness, which allowed unit testing of the Processor. I am looking for something similar for the stateless processor. Any pointers or link to sample code would be greatly appreciated. Regards,Ahmed.
