Hi all,

Say I assign timestamps to a stream and then apply a transformation like
this:

stream.keyBy(0).timeWindow(Time.hours(5)).reduce(count).timeWindowAll(Time.days(1)).apply(transformation)

Now, when the first window is applied, events are aggregated based on their
timestamps, but I don't understand what timestamp will be assigned to the
aggregated result of the reduce operation for the second window to process
it. Could you please explain it? Thank you.

Best,
Yassine
