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
