This looks great. We use our own version of something much more naive which allows for the various benefits you have (but yours does more). Ours is also based on Linear but we go all in on mobx like they do too. It’s a great model where we have optimistic updates and a natural object graph to work with in typescript. I’ll have a play with this to see if it could eventually be used as a replacement.
Noticed in your docs you say that Hasura uses RLS for permissions but that’s not true. They have their own language for effectively specifying the filters to apply on a query. It’s a design decisions that allows them to execute the same query for all connected clients at the same time using different parameters for each one.
I didn’t clock the use of “triples” as the store on first read. That’s a non-starter for existing dbs and pretty much a dead end for anyone who eventually wants a db structure they can use outside of this model.
We are working on a Postgres adapter. If you have an existing app and would be interested in using Instant with it, please send us a note: founders@instantdb.com
The way the Postgres adapter would work: You give us your database url [1], and Instant handles the real-time sync. [2]
For roll-out, we'll test it ourselves first and then take on beta users.
