Hi!
We are testing the following 3 way time windowed join to keep the retained
state size small. Using joins for the first time here. It works in unit
tests but we are not able to get expected results in production. We are
still troubleshooting this issue. Can you please help us review this in
(?). Is that what is going
on? Can someone confirm? Is there a way to flush out periodically?
Thanks,
Vinod

Although things improved during bootstrapping and when even volume was
larger. As soon as the traffic slowed down the events are getting stuck
(buffered?) at the OVER operator for a very long time. Several hours.

We have a SQL based flink job which is consume a very low volume stream (1
or 2 events in few hours):
*SELECT user_id,COUNT(*) OVER (PARTITION BY user_id ORDER BY rowtime
RANGE INTERVAL '30' DAY PRECEDING) as count_30_days,
COALESCE(occurred_at, logged_at) AS latency_marker,

Hi!
We are using apache-flink-1.4.2. It seems this version doesn't support
count(DISTINCT). I am trying to find a way to dedup the stream. So I tried:
SELECT
CONCAT_WS(
'-',
CAST(MONTH(longToDateTime(rowtime)) AS VARCHAR),
CAST(YEAR(longToDateTime(rowtime)) AS VARCHAR),
every x months on
2nd day at 01:34:00.000 PST? Same thing with years.
Thanks,
Vinod

Resetting things based on larger windows (month, quarter, year) can be
quite useful. Is there a practical limitation with Flink (state size blows
up?) for not supporting such large windows?

Doh! Sorry about that! :)
Thanks again!
