we are spicedb users and our company has a new legal requirement being able to do time travel queries ( snapshot in time). Will such a capablity be built in the future ( i do not see a git issue) or possibility to store meta (key value) at permission level?
v
time travel API calls already exist with 
at_exact_snapshot
consistency
adding metadata to relationships is not planned, feel free to open an issue

@ankurb what's the ask?
theoretically you could get what you're asking for if you take backups on the same cadence as your configured garbage collection window and keep track of the set of zedtokens through some other mechanism
and what would the metadata be for?
a
filtering
prefiltering the rows before spicedb would calculate
if i have 5 snapshotsover 5 days the at_exact_snapshot is about consistency on accuracy of latest data, is there a way i can query specific snapshots?
y
at_exact_snapshot
isn't latest
that's 
fully_consistent
at_exact_snapshot
says "give me an answer according to what the world looked like at the timestamp associated with this revision"
what do you mean by "prefiltering the rows?"
like it sounds like you have an approach or an optimization in mind, but what's the problem that it would solve?
a
let me try out the zedtoken
