Description

When the SlideWindow deal with the ContinuousProcessingTimeTrigger or ContinuousEventTimeTrigger will trigger all the related slide window to process, but when user only care about the data like the recent 30 days, the slidewindow's maxTimestamp which exceed today is not need to be process, so i think we should add support to filter the slidewindow rather than ask user to filter in the windowProcessFunction. What's your idea aljoscha
