Major improvements

Prisma Client tracing support (Preview)

We're excited to announce Preview support for tracing in Prisma Client! 🎉

Tracing allows you to track requests as they flow through your application. This is especially useful for debugging distributed systems where each request can span multiple services.

With tracing, you can now see how long Prisma takes and what queries are issued in each operation. You can visualize these traces as waterfall diagrams using tools such as Jaeger, Honeycomb, or DataDog.

Read more about tracing in our announcement post and learn more in our documentation on how to start working with tracing.

Try it out and let us know what you think.

Isolation levels for interactive transactions

We are improving the interactiveTransactions Preview feature with the support for defining the isolation level of an interactive transaction.

Isolation levels describe different types of trade-offs between isolation and performance that databases can make when processing transactions. Isolation levels determine what types of data leaking can occur between transactions or what data anomalies can occur.

To set the transaction isolation level, use the isolationLevel option in the second parameter of the API. For example:

await prisma.$transaction(
  async (prisma) => {
    // Your transaction...
  },
  {
    isolationLevel: Prisma.TransactionIsolationLevel.Serializable,
    maxWait: 5000,
    timeout: 10000,
  }
)

Prisma Client supports the following isolation levels if they're available in your database provider:

• ReadCommitted
• ReadUncommitted
• RepeatableRead
• Serializable
• Snapshot

Learn more about in our documentation. Try it out, and let us know what you think in this GitHub issue.

Renaming of Prisma Client Metrics

In this release, we've renamed the metrics — counters, gauges, and histograms — returned from prisma.$metrics() to make it a little easier to understand at a glance.

Syntax highlighting for raw queries in Prisma Client

This release adds syntax highlighting support for raw SQL queries when using $queryRaw`` and $executeRaw`` . This is made possible using Prisma's VS Code extension.

Note: Syntax highlighting currently doesn't work with when using parentheses, (), $queryRaw(), $executeRaw(), $queryRawUnsafe(), and $executeRawUnsafe().

If you are interested in having this supported, let us know in this GitHub issue.

Experimental Cloudflare Module Worker Support

We fixed a bug in this release that prevented the Prisma Edge Client from working with Cloudflare Module Workers.

We now provide experimental support with a workaround for environment variables.

Try it out and let us know how what you think! In case you run into any errors, feel free to create a bug report.

Upgrade to Prisma 4

In case you missed it, we held a livestream a few weeks ago and walked through issues you may run into while upgrading to Prisma 4 and how to fix them!

Request for feedback

Our Product teams are currently running two surveys to help close the feature gaps and improve Prisma.

If you have a use-case for geographical data (GIS) or full-text search/ indexes (FTS), we would appreciate your feedback on your needs:

• Prisma GIS User Research Survey
• Prisma Full-Text Search User Research Survey

Many thanks! 🙌🏽
