getstream aggregate feed - group by time with strftime

Question

My goal is to aggregate activities together, but only if they happen within x amount of minutes within each other.

It looks like I need to use the strftime syntax. Using this syntax is it possible? I am also confused about which activity property I assign this group string to.

Thanks!

Answer 1

You can use strftime to ensure activities that happen in the same hour or in the same day are grouped together. It needs to be a fixed window though, it can't be based on the distance between activities.

Note that on enterprise plans we can setup custom aggregation formats that can handle more complex use cases. (such as the grouping you're looking for)
