Hello Dominik,
Thanks for the information. Since my window is getting triggered every 10
seconds, the results I am getting before 5 minutes would be irrelevant as I
need to consider data coming in every 5 minutes. Is there a way I can skip the
results that are output before the first 5 minutes?
Thanks and Regards,Piyush Shrivastava

Piyush,
You created sliding window witch is triggered every 10 seconds
Flink fires up this window every 10 seconds, without waiting at 5 min buffer to
be filled up
It seems to me that first argument is rather "maximum data buffer retention"
than " the initial threshold"

Hi all,I wanted to know how exactly sliding windows produce results in
Flink.Suppose I create a sliding window of 5 minutes which is refreshed in
every 10 seconds:
.timeWindow(Time.minutes(5), Time.seconds(10))
So in every 10 seconds we are looking at data from the past 5 minutes. But what
happens before the initial 5 minutes have passed?Suppose we start the
computation at 10:00. At 10:05 we will get the result for 10:00-10:05. But what
are the results which we get in between this? i.e. at 10:00:10, 10:00:20 and so
on.Basically why do Flink start producing results before the initial threshold
has passed? What do these results signify? Thanks and Regards,Piyush Shrivastava
