I've to join two stream where one stream is coming late. So, I planned doing it by creating two windows, for first window the size will be 5 minutes and for the other it will be 10 minutes. Then, I'll perform the join operation. Is my solution correct because I don't know whether one window will sync with other or not because one is getting finished earlier and another is late. If there is a better way to achieve the same, please let me know.
