Why

Document + graph + key-value in one. 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 multi-model needs. Avoid for single-model simplicity.

How

1. docker run arangodb:3.12 2. Connect with driver 3. Create collections 4. Query with AQL 5. Add environment configuration — cp .env.example .env && edit values 6. Run tests — npm test or pnpm test to verify setup 7. Deploy — git push to trigger CI/CD or manual deploy

Example

await db.collection('users').save({ name: 'Alice' }) const cursor = await db.query(aql`FOR u IN users RETURN u`)

Common Problems

⚠AQL syntax — learn the FOR...RETURN pattern
⚠Sharding — use for horizontal scaling
⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

✓Use SmartGraphs for graph sharding
✓Leverage Foxx for microservices
✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is ArangoDB Multi-Model and what projects is it for?

ArangoDB for multi-model data. 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 ArangoDB Multi-Model in 10 minutes?

Two steps: (1) docker run arangodb:3.12; (2) Connect with driver. 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 ArangoDB Multi-Model and how do I avoid it?

The most common pitfall is: AQL syntax — learn the FOR...RETURN pattern. 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 ArangoDB Multi-Model?

Best practices for ArangoDB Multi-Model include: Use SmartGraphs for graph sharding; Leverage Foxx for microservices; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use SmartGraphs for graph sharding" — should be set up at project init to avoid costly rework later.

When should I NOT choose ArangoDB Multi-Model?

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). ArangoDB Multi-Model shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
