Re: Some doubts about window start time and end time

[Jun Zhang]

Hi??Caizhi ??


the code like this :




dataStream
.keyBy(??device")
.window(TumblingProcessingTimeWindows.of(Time.hours(6)))
.trigger(ContinuousProcessingTimeTrigger.of(Time.seconds(5)))

                               
 .aggregate(new MyAggre(), new WindowResultFunction())   
                      
           .print();



I add a trigger for quick output

Hi:
I defined a Tumbling window, I set the time size to one hour, and the resulting 
windows are [00: 00: 00-01: 00: 00], [01: 00: 00-02: 00: 00]. ....
This meets my expectations, but when I set the time size to 6 hours, the 
resulting window size is [02: 00: 00-08: 00: 00], [08: 00: 00-14: 00: 00], [14: 
00: 00-20: 00: 00] ...
But my expected window size is [00: 00: 00-06: 00: 00], [06: 00: 00-12: 00: 00] 
...
Is it right to get such a window result?



thanks
