FeatureGlobal ACID

Why

PG-compatible, global, strongly consistent. PostgreSQL is used by nearly 50% of professional developers, making it the most popular database (Stack Overflow 2024).

SQLite powers 1 trillion+ active databases (every iOS/Android device), and DuckDB emerged as the fastest OLAP engine for analytics, 5-10x faster than ClickHouse for single-node queries.

When

Use for global apps. Avoid for single-region (use PG).

How

1. Create CockroachDB cluster 2. Get PG connection string 3. Connect with pgx 4. Use geo-partitioning

Example

const pool = new Pool({ connectionString: process.env.DATABASE_URL }) await pool.query('INSERT INTO users (id, name) VALUES (1, $1)', ['Alice'])

Common Problems

⚠Latency — use geo-partitioning for local reads
⚠Cost — higher than single-region PG
⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

✓Use CockroachDB Cloud for management
✓Leverage PG compatibility
✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is CockroachDB and what projects is it for?

CockroachDB for globally distributed ACID. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.

How do I spin up a working demo with CockroachDB in 10 minutes?

Two steps: (1) Create CockroachDB cluster; (2) Get PG connection string. Get the local dev server running, then wire one real data source to verify the end-to-end loop.

What is the most common pitfall with CockroachDB and how do I avoid it?

The most common pitfall is: Latency — use geo-partitioning for local reads. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.

What are the best practices for CockroachDB?

Best practices for CockroachDB include: Use CockroachDB Cloud for management; Leverage PG compatibility; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use CockroachDB Cloud for management" — should be set up at project init to avoid costly rework later.

When should I NOT choose CockroachDB?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). CockroachDB shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
