Features

Cross-cutting capabilities of prisma/prisma — things that span multiple packages and need a per-feature narrative. Each page here ties together the relevant packages with sequence diagrams and code references.

Pages

• Driver adapters — how Prisma 7 talks to databases through JS drivers
• Query execution — request → query plan → SQL → response, end to end
• Transactions — interactive and batch transactions, savepoints, isolation levels
• Migrate flow — prisma migrate dev walked through, including Schema Engine RPC
• Schema Engine RPC — the JSON-RPC contract and transports
• Client generation — how prisma generate runs each generator
• SQL Commenter plugins — plugin lifecycle and runtime
• Studio — how prisma studio boots and runs

Why a "features" lens?

The repo has lots of structural homes (packages, generators, adapters), but several capabilities are distributed across packages. Driver adapters are a perfect example: the contract is in driver-adapter-utils, the runtime that talks through it lives in client-engine-runtime and client, the user-facing constructor option is in client, and there are nine adapter packages. Documenting it under any single package would either bury the cross-cutting view or duplicate content. The features lens fixes that.

Pages here intentionally cross-link rather than duplicate. The detailed per-package docs stay in Packages; the features pages summarize the moving parts and the data flow.
