How "experimental" is the Transaction API? Is it solid enough to rely on? I don't need to do complex things with it, just creations.

It’s stable since 2.11.0 🙂 https://github.com/prisma/prisma/releases/tag/2.11.0

It’s already stable in the latest release, but it’s different from the transactions that traditional ORM’s offer. You can read more about that here.

Thanks!
