I have to admit that as much as I do love Prisma, it's painful realization, that subscriptions are still (since Graphcool) on kind of sidetrack and never getting enough attention to get those done properly, now even with broken filtering and need to handle that on a server side
I am already thinking to do some sort of tech split and use Prisma more like a long therm storage and use Firestore for a realtime data and hide both of these behind single GraphQL schema ... it's not exactly dream way to go, but at least it will be reliable 😕
