------------------------------------
Hi [~fhueske] I have opened the PR. In the
PR(https://github.com/apache/flink/pull/4157). I have add supports updating the
calculated data according to the specified time interval on non-window group
AGG. If we config the time interval is N seconds, then the next update time
relative to the latest update time T, is T+N seconds. For example, the time
interval is 2 seconds, the previous update time is T seconds, and the next
update time T1> = T + 2 seconds. If no data arrives during T to T + 2, no
updates are made.
I appreciated if you have time to look at the PR. And feel free to left your
comments. :)
