PlanetScale & Vitess MySQL horizontal scaling
We scale MySQL workloads horizontally with PlanetScale and Vitess, enabling non-blocking schema migrations and automated sharding.
Core capabilities
Why we build with PlanetScale
02
Git-like database branching
Testing schema changes in isolated development branches before merging to main production.
03
Horizontal sharding with Vitess
Distributing large MySQL tables across multiple database nodes with transparent query routing.
Use cases
Where PlanetScale fits
Fast-moving SaaS teams
Shipping frequent database schema updates without fearing schema migration locks.
Global high-concurrency applications
Heavy concurrent read and write traffic spread across sharded database clusters.
How we staff it
PlanetScale engineers you interview first
Seniority and experience are agreed in the proposal, and you interview every engineer before they start.
Working-hours overlap is agreed for each engagement and written into the statement of work — the shared window, who shifts hours, and how handoffs work outside it.
Technical FAQs
Frequently asked engineering questions
PlanetScale uses Vitess's VReplication engine to create a shadow table, sync data in the background, and perform a momentary metadata cutover.
PlanetScale supports foreign key constraints natively or can manage relationship integrity at the application/Vitess level for sharded environments.
