Postgres: Count number of users actions within time interval
3
I am trying to count kind of DAU by specified actions, where users are divided into categories by number of their actions within some interval.
Raw data example:
date user_id amount_actions
2018-12-01 1 2
2018-12-02 1 1
2018-12-10 1 1
2018-12-01 2 2
2018-12-02 2 1
2018-12-10 3 1
Result table I wish I could have:
date user_id amount_actions rolling_sum_7_days
2018-12-01 1 2 2
2018-12-02 1 1 3
2018-12-10 1 1 1
2018-12-01 2 2 2
2018-12-12 2 1 1
2018-12-10 3 1 1
2018-12-15 3 1 2
Thanks.

You can do a lateral join that calculates the sum of actions for that user in the past seven days:
select date
, user_id
, amount_actions
, sum_actions
from YourTable yt1
cross join lateral
(
select sum(amount_actions) as sum_actions
from YourTable yt2
where yt1.user_id = yt2.user_id
and yt1.date - interval '7 days' < yt2.date
and yt2.date <= yt1.date
) sum_actions
Working example at rextester.
