Hi All,

I was looking at the documentation for windows and got a little confused.
As per my understanding tumbling window per key will create a non
overlapping window based on when the data for that key arrived. For example
consider a tumbling window of 30 seconds
user1 - 10:01:01
user2 - 10:01:02
user1 - 10:01:05
user2 - 10:01:06
user2 - 10:01:08

Result:
user1 (10:01:01 & 10:01:05)
user2 (10:01:02 & 10:01:06)
user2 (10:01:08)

Is this the right understanding?

But as per the below image in docs, it looks like the window is not per
key, please correct me if i'm wrong.
