Does dgraph support the data expiration mechanism? Because the data we need to store may be time-sequential. At present, I have not seen the TTL setting from the official website.
No, there is no TTL from the data aspect. You would have to manually clean up the data using either the SPO SP* or S** methods.
I’m assuming that your date sequence would be a valye (O in the SPO model) so you would have to do an upsert to gather and delete the data you want to “clean-up”
