Prisma: 4.12.0 Release

🌟 Help us spread the word about Prisma by starring the repo or tweeting about the release. 🌟

Highlights

Introspection of Views SQL improvements (Preview)

The views Preview feature significantly improved this release: prisma db pull now reads the SQL query used to define a view and stores it in a .sql file in a views folder next to your Prisma schema.

Note: These .sql files are not yet used for creating or updating views during migrations yet. For now, we are only looking for feedback. Let us know if the introspected SQL files match the views picked up in your database and if the correct files were created in your filesystem.

We encourage you to leave feedback in this GitHub issue.

Improvements to JSON protocol (Early Preview)

In 4.11.0, we announced the jsonProtocol Preview feature which had some rough edges. This release improves the Preview feature by providing polished and helpful error messages from Prisma Client when something goes wrong. Here is an example error message:

We would appreciate it if you would try it out to help us polish the feature and move it to General Availability. Testing it requires little effort. Please also leave any feedback in this issue, or open a new one if you want to report a bug.

Prisma Client startup performance

In this release, we've improved the startup performance of Prisma Client. We're keen on improving the performance of Prisma Client. If you experience any problems with the startup performance, be sure to report them so that we can look into them.

Open Telemetry tracing and logging for Prisma Client for Data Proxy

This release adds support for Open Telemetry tracing (via the tracing Preview feature) and logging to Prisma Client for Data Proxy.
