[Flink 6649][table]Improve Non-window group aggregate with update intâ¦
In this PR. 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.
