Prisma Client will now automatically determine how it should connect to the database depending on the protocol in the connection string. If the connection string starts with prisma://, Prisma Client will try to connect to your database using Prisma Accelerate or Prisma Data Proxy.
Prisma Studio now works with Prisma Data Proxy and Prisma Accelerate.
We’ve introduced a new --no-engine flag which will prevent a Query Engine file from being included in the generated Prisma Client. This flag will also help ensure the bundle size of your application remains small by excluding the Query Engine files from the generated Prisma Client.
prisma generate --no-engine
The --data-proxy and --accelerate flags have not been removed but are now aliases for the new --no-engine flag.
We recommend using the --no-engine flag when generating Prisma Client that uses either Accelerate or Data Proxy.
Simplified connection string override in Prisma Client
This release simplifies the API used when programmatically overriding the connection string by introducing the datasourceUrl property in Prisma Client’s constructor. This means you do not have to use the datasource name defined in your Prisma schema.
const prisma = new PrismaClient({
datasourceUrl: "postgresql://johndoe:randompassword@localhost:5432/mydb",
})
Use LIMIT in one-to-many relations on a single parent
In cases where there is a single parent with a one-to-many relation included (findFirst, findUnique, findMany({ take: 1 })), we now utilize LIMIT at the database level to restrict the number of related items returned instead of retrieving all related items into memory and performing a take in memory.
For situations where you have many related objects but only need a few, you should see a dramatic improvement in speed and memory usage.
Note: we are still working on bringing this improvement to other parts of Prisma Client in upcoming releases. If multiple parent records are returned, the previous behavior is used.
Further improvements for nested writes
Thanks to our introduction of using RETURNING in some cases in 5.1.0, we could now improve performance in nested writes by removing reload nodes. This will now result in one less query per relation traversed in a nested write. For more info, check out the pull request.
