Hi Sonex

All windows under the same key (e.g., TimeWindow(0, 3600) and TimeWindow(3600, 7200)) will be processed by the flatmap function. You can put the variable drawn from TimeWindow(0, 3600) into a State. When you receive TimeWindow(3600, 7200), you can access the state and apply the function with the obtained variable.

Regards,

Xiaogang

主　题：Re: 回复：Transfer information from one window to the next

I don`t think you understood the question correctly. I do not care about
information between windows at the same time (i.e., start of window = 0, end
of window 3600). I want to pass a variable, let`s say for key 1, from the
apply function of window 0-3600 to the apply function of window 3600-7200,
for key 1.
