Understanding databases

This document explains the basic ideas behind databases in the PlanetScale database context.

What is a PlanetScale database?

A PlanetScale database is like a MySQL database that can scale horizontally using sharding. Each database runs on a cluster.

You can assign resources to each database at the time of database creation. You can also choose to create replicas of particular databases to improve availability and serve more read traffic.
