PlanetScale MySQL Database

PlanetScale is a serverless MySQL database platform built on Vitess, the open-source database clustering system originally developed at YouTube for horizontal sharding of MySQL databases, founded by Jiten Vaidya and Sugu Sougoumarane, two of the original Vitess engineers, in 2018, headquartered in Mountain View, providing a MySQL-compatible serverless database with branch-based schema management, non-blocking schema migrations, global read replicas, and connection pooling through the Vitess proxy, adopted by GitHub, Priceline, Square, and Robinhood for their database infrastructure, with Vitess proven at YouTube scale handling trillions of queries per day. The branching feature applies the Git workflow to database schemas, enabling developers to create database branches from a production database containing the schema and optionally a subset of data, with schema changes applied to the branch, tested against representative data, and promoted to production through deploy requests with conflict detection and resolution, eliminating risky production migrations and enabling database schema changes through the same pull request workflow used for application code. The non-blocking schema migrations use online schema change tools that copy data to a shadow table with the new schema, track changes through binlog replication, and atomically swap tables when complete, enabling schema changes on tables with billions of rows without locking or downtime, with the migration progress visible in the dashboard. The serverless scaling automatically provisions and scales compute and storage resources, with connection pooling through the Vitess proxy enabling thousands of concurrent connections from serverless and edge environments. The read replicas across global regions. The point-in-time recovery. The audit logging. Designed by Vitess engineers. Designed for engineering teams.
