I have an event and cache that suppose to add this event on each occurrence.
I have to build CQL query with following logic:
The same event happened three times during defined period of time (let's say last 7 days) .
Any help would be appreciated .
One way to go is to build a 2 stage flow:
First a view with a time window. Some thing like:
select myField as field, count(*) as count .....
from myChannel [range 7 days slide 1 hour]
group by userID
Then a query that uses the view:
select field, .....
where count = 3
This will give every hour a list of user ID (events) that in the last 7 days
Please note that the events will continue to be created every 1 hour until the window will slide to such a place that count < 3.
If you want to have the event output only 1 time and not every hour you can also put it in a cache (the output of the query) and add it to where clause in the query. Something like
where count = 3 and filed not in cache.
Hope this helps
Thank you,884793 (Sorry,I don't know your name ),
I believe that I missed some important information in my post.
I don't have continuous flow of event .
Time difference from event to event can be an hour or day.
