Re-Hi,

I have another question regarding the triggering of the processing of a window. 
Can this be done in some way at specific time intervals, independent of whether 
 an event has been received or not, via a trigger?

The reason why I am considering a trigger rather than timeWindow(All) is that 
timeWindow will end up generating multiple windows and duplicating data, while 
having the option from the trigger to actually fire the processing at certain 
times, independent of when the events arrived) would enable to operate with a 
single window.
