Auto-computed predicates

Say I want to group dateteime data stored in dgraph into buckets of 10 minute resolutions. Eg.

10:27:23 should go to the bucket 10:20:00
10:31:12 should go to the bucket 10:30:00

(date part omitted)

My current assumption is that the group_by on a datetime field doesn’t permit me doing that.

So instead when inserting or updating data I would like to auto-compute an additional field timestamp_computed according to that “rule”.

Is that possible or would this be the responsibility of the inserting client?

group_by works only on edges, not values.

There’s no auto-compute feature in Dgraph.
