Is Prisma's JSON format still constrained by 256 KB max size? I'm creating apps with larger tree structures, which are not the best match neither GraphQL nor for relational databases. Would like to keep em in JSON and handle tree operations client side. It says here https://www.graph.cool/docs/reference/database/data-modelling-eiroozae8u, but i'm not sure whether this is subject to current of future change?
