Description

In documentation of windows, we have the following example code:

// sliding processing-time windows offset by -8 hours
input
    .keyBy(<key selector>)
    .window(SlidingProcessingTimeWindows.of(Time.hours(12), Time.hours(1), Time.hours(-8)))
    .<windowed transformation>(<window function>);

Unfortunately, it will raise as the absolute value of offset must be less than the slide.
