Prisma + MariaDB in production: lessons from 50 deployments

Driver adapters, connection pooling, migrations on deploy and zero-downtime schema changes.

By GoDesine Admin

Prisma’s driver adapters make MariaDB a first-class, lightweight choice for TypeScript apps.

Use the MariaDB driver adapter

The adapter runs on the native mariadb driver — no binary query engine to ship — which keeps deployments small and cold starts fast.

Set a sensible connectionLimit per process and reuse one client instance across hot reloads.

Run prisma migrate deploy in your deploy script before restarting the app. Make schema changes backwards-compatible: add, backfill, then remove.

Cents in an INT column avoid floating-point surprises entirely.

How we decide between cross-platform and fully native for every app we build — with real costs, timelines and trade-offs.

Partial prerendering, the React Compiler and smarter caching: how we hit sub-second LCP on every production site in 2026.

Access control, reentrancy, oracle risks, upgradeability and gas — the 25 checks that stand between your protocol and an exploit.
