Hi,
The documentation mentions the possibility to use a negative offset with
a TumblingEventTimeWindows :
// daily tumbling event-time windows offset by -8 hours.input
.keyBy(<key selector>)
.window(TumblingEventTimeWindows.of(Time.days(1), Time.hours(-8)))
.<windowed transformation>(<window function>);
But the code will throw an IllegalArgumentException :
if (offset < 0 || offset >= size) {
throw new IllegalArgumentException("TumblingEventTimeWindows
parameters must satisfy 0 <= offset < size");
}
Regards,
Vladislav
