PlanetScale MySQL
PlanetScale for managed MySQL at scale.
Stack Components
Why
Vitess sharding, schema branches, no downtime. 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 large MySQL apps. Avoid for single-region small apps.
How
Example
Common Problems
- ⚠Branch workflow — use for schema changes
- ⚠Sharding — understand Vitess sharding keys
- ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical
Best Practices
- ✓Use deploy requests for review
- ✓Leverage online schema changes
- ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

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