💡 Quick Start: Follow these 1 steps in order to get up and running with PlanetScale quickly.
Explore the key features that make PlanetScale powerful for cloud infrastructure workflows.
Git-like branching for database schemas enabling isolated testing and non-disruptive schema deployments
Testing schema migrations in isolated environments before deploying to production without affecting live data
Zero-downtime schema migrations using online DDL operations and intelligent query routing
Adding indexes or columns to large tables during peak traffic without causing application outages
Automatic sharding and query routing built on Vitess technology for handling massive MySQL workloads
Scaling MySQL beyond single-server limitations for applications with hundreds of millions of rows
Detailed analytics on query performance, slow queries, and optimization recommendations with visual charts
Identifying performance bottlenecks and optimizing database queries without installing additional monitoring tools
Built-in connection pooling with serverless compute that scales based on actual usage patterns
Handling variable application traffic without managing connection limits or database capacity planning
Schema change safety checks preventing destructive operations and migration rollback capabilities
Preventing accidental data loss during schema changes with automated safety validations and easy rollback
PlanetScale is highly compatible with standard MySQL applications but has limitations. Foreign keys aren't supported due to distributed architecture, and some MySQL features like stored procedures have restrictions. Most applications require minimal changes, but review compatibility docs before migration.
You create a branch, make schema changes, test with sample data, create a deploy request (like a pull request), and merge to main branch. This workflow integrates with CI/CD pipelines and ensures schema changes are tested before production deployment.
Large migrations use online DDL operations that process changes incrementally without locking tables. The system automatically handles the complexity of maintaining data consistency during migration. Most schema changes complete without affecting application performance or availability.
Pricing is based on storage, reads, and writes rather than fixed instance sizes. The free tier is generous (5GB storage, 1B row reads). Costs scale with usage, which benefits variable workloads but may be more expensive than dedicated instances for consistently high-utilization databases.
Yes, PlanetScale provides data export capabilities and migration tools. Since it's MySQL-compatible, you can migrate to other MySQL providers using standard tools like mysqldump. However, you'll need to adapt any schema changes that used PlanetScale-specific workflows.
Now that you know how to use PlanetScale, it's time to put this knowledge into practice.
