Highlights

Improved serverless experience — smaller engines size

In this release, we have decreased the size of our engine files by an average of 50%. The size of the Query Engine used on Debian, with OpenSSL 3.0.x, for example, went from 39MB to 14MB. We will also remove some smaller engines to decrease the total size in future versions.

Additionally, we have started optimizing how the Prisma schema is loaded in Prisma Client. You should notice a considerable improvement when executing the first query if you're working with a bigger schema with many models and relations.

We will continue investing in this direction in the next releases and further improve the experience with Prisma and serverless environments.

Multi-schema support for CockroachDB (Preview)

We're pleased to share that this release adds Preview support for multi-schema for CockroachDB. 🎉

This release adds support for:

• Introspecting databases that organize objects in multiple database schemas
• Managing multi-schema database setups directly from Prisma schema
• Generating migrations that are database schema-aware with Prisma Migrate
• Querying across multiple database schemas with Prisma Client

If you already have a CockroachDB database using multiple schemas, you can quickly get up and running set up multiple schemas by:

• Enabling the Preview feature in the Prisma schema
• Defining the schemas in the schemas property in the datasource block
• Introspecting your database using prisma db pull

You can further evolve your database schema using the multi-schema Preview feature by using prisma migrate dev.

For further details, refer to our documentation and let us know what you think in this GitHub issue.

Improved OpenSSL 3.x support

Prisma now supports OpenSSL 3 builds for Linux Alpine on x86_64 architectures. This particularly impacts users running Prisma on node:alpine and node:lts-alpine Docker images. The images are based on an Alpine version that ships with OpenSSL 3.0.x, which isn’t compatible with OpenSSL 1.1.x (already supported by Prisma). You can read more details about it in this GitHub comment.

We also have rewritten our OpenSSL version detection logic, making it future-proof. We now expect Prisma to support systems running with any OpenSSL 3 minor versions out of the box.
