Request for feedback for Preview features

We would appreciate your feedback on a handful of Preview features to help us move them to General Availability soon. The Preview features include:

• PostgreSQL extensions
• Extended where unique
• Field reference support
• Order by Nulls
• Count by filtered relation

You can test them by enabling the Preview feature in your Prisma schema and giving them a try already in your Prisma schema, e.g., PostgreSQL extensions, or regenerating Prisma Client and trying them in your queries.

Highlights

Improved Prisma Client startup performance

For the last couple of months, we've been working hard to improve the performance of Prisma Client. We also published a blog post on how How We Sped Up Serverless Cold Starts with Prisma by 9x, which we recommend you give it a read.

This release continues with the same theme by making the size of the generated Prisma Client smaller. We have roughly halved the size of Prisma Client's dependencies.

More Introspection warnings for unsupported features

In 4.13.0, we introduced the first 6 introspection warnings that surface the existence of these features in your database and link to our documentation on how to manually work around the Prisma Schema with unsupported database features.

In this release, we added 3 more introspection warnings for the following features:

• Check Constraints (MySQL + PostgreSQL)
• Exclusion Constraints
• MongoDB $jsonSchema

On introspecting a database using any of these features, you will get a warning from the Prisma CLI and a comment in your Prisma schema where the feature is being used. The warning will also contain a link to instructions on how to manually use the feature.
