Hi, I have video analytic data: - time - object type (car, person, etc) - object bounding box (x,y,width,height) - track id
I'd like to do transformations where I need to process detections belonging to the same track in time order. My input data is ordered by time. I do some filtering first (eg.: filter cars) than apply sliding windows (eg.: 10 sec window size, with 5 sec step) and group by track id. Can we assume anything about the order of events in the windows? Is the order preserved? I need to process them in time order, if the order is not preserved what would be the best approach? I can of course collect and sort the data but it has significant performance and memory impact. (I need to process events on the billion scale).
