Are you using Flink SQL? If using Flink SQL, the window is triggered when and only when the special data (with the expected timestamp after watermark) enters. It is not possible to trigger the window without changing the window-start and window-end column.

I have a lot of jobs run in window tumble (3H) and when they are all triggered at the same time, it causes performance problems. If somehow I can delay some of them 10-15 minutes , without changing the original data in the window and window-start, window-end dates, it would be great. Thanks Kenan
