Description

 

srcStream
.timeWindowAll(Time.seconds(60))
.trigger(ContinuousProcessingTimeTrigger.of(Time.seconds(10)))...

 

 This can correctly calculate the following interval result : 0-10s 10-20s 20-30s 30-40s 40-50s

But this lost data which was send in 50-60s.

Because when the first window ends, the time is 59.9999s, it is not equal to window-end-time(60s).So it will not enter the if judgment.
