What your trying to do is very difficult (particularly since your data views are relying upon joins and group queries.) You may need layered solutions. I've been looking at https://deepstream.io for keeping clients in sync. You will still have to watch the db, though the client and back end sync is handled!

I'm interested in this problem also! I think there is a large overlap with projects that market/focus on offline-first experiences. AFAIK this problem can be solved by: 1) Considering a client-side copy of the database that gets synced with the remote DB. This is an approach [PowerSync](https://www.powersync.com/) and [ElectricSql](https://electric-sql.com/) and [rxdb](https://rxdb.info/) take!

Pocketbase [0] is a possibility. It offers a way to subscribe to collections, meaning the client will be notified if any of the records in that collection change. [1] Should be quite efficient too, the FAQ claims that 10k realtime connections on a small hetzner VPS is no problem [2] [0] https://pocketbase.io/.
