# CockroachDB Setup
|
|
|
|
Configure Prisma with CockroachDB.
|
|
|
|
## Prerequisites
|
|
|
|
- CockroachDB cluster
|
|
|
|
## 1. Schema Configuration
|
|
|
|
In `prisma/schema.prisma`:
|
|
|
|
```prisma
|
|
datasource db {
|
|
provider = "cockroachdb"
|
|
}
|
|
|
|
generator client {
|
|
provider = "prisma-client"
|
|
output = "../generated"
|
|
}
|
|
```
|
|
|
|
## 2. Config Configuration
|
|
|
|
In `prisma.config.ts`:
|
|
|
|
```typescript
|
|
import { defineConfig, env } from 'prisma/config'
|
|
|
|
export default defineConfig({
|
|
schema: 'prisma/schema.prisma',
|
|
datasource: {
|
|
url: env('DATABASE_URL'),
|
|
},
|
|
})
|
|
```
|
|
|
|
## 3. Environment Variable
|
|
|
|
In `.env`:
|
|
|
|
```env
|
|
DATABASE_URL="postgresql://user:password@host:26257/db?sslmode=verify-full"
|
|
```
|
|
|
|
Note: CockroachDB uses the PostgreSQL wire protocol, so the URL often looks like postgresql, but the provider **MUST** be `cockroachdb` in the schema to handle specific CRDB features correctly.
|
|
|
|
## Driver Adapter
|
|
|
|
Use a driver adapter for the standard SQL workflow. CockroachDB is PostgreSQL-compatible, so use the PostgreSQL adapter.
|
|
|
|
1. Install adapter and driver:
|
|
```bash
|
|
npm install @prisma/adapter-pg pg
|
|
```
|
|
|
|
2. Instantiate Prisma Client with the adapter:
|
|
```typescript
|
|
import 'dotenv/config'
|
|
import { PrismaClient } from '../generated/client'
|
|
import { PrismaPg } from '@prisma/adapter-pg'
|
|
|
|
const adapter = new PrismaPg({ connectionString: process.env.DATABASE_URL })
|
|
const prisma = new PrismaClient({ adapter })
|
|
```
|
|
|
|
## ID Generation
|
|
|
|
CockroachDB uses `BigInt` or `UUID` for IDs efficiently.
|
|
|
|
```prisma
|
|
model User {
|
|
id BigInt @id @default(autoincrement()) // Uses unique_rowid()
|
|
}
|
|
```
|
|
|
|
Or using string UUIDs:
|
|
|
|
```prisma
|
|
model User {
|
|
id String @id @default(dbgenerated("gen_random_uuid()")) @db.Uuid
|
|
}
|
|
```
|
|
|
|
## Common Issues
|
|
|
|
### Schema Introspection
|
|
Always use `provider = "cockroachdb"` to ensure correct type mapping during `db pull`.
