[GitHub] [beam] kennknowles opened a new issue, #18188: outputWithTimestamp() accepts timestamps that will fail preconditions

kennknowles opened a new issue, #18188:
URL: https://github.com/apache/beam/issues/18188

   We have accidentally created events with *wrong* timestamps in the future which are accepted by
   outputWithTimestamp(), but will fail at a later step:
   
   java.lang.IllegalStateException: Timer 472976-06-15T20:09:57.269Z is beyond end-of-time
           at Preconditions.checkState(Preconditions.java:199)
           at ReduceFnRunner.scheduleEndOfWindowOrGarbageCollectionTimer(ReduceFnRunner.java:1050)
   [...]
   
   Would it make sense to implement a check already at outputWithTimestamp() level to fail early?
