PlanetScale Vectors GA: A Game-Changer for MySQL and AI Databases
Security Boulevard, Monday, April 14th, 2025
PlanetScale has announced that vector support is now generally available. This feature allows vector data to be stored alongside relational MySQL data, eliminating the need for a separate vector database.
The implementation is based on a fork of MySQL and includes advanced capabilities such as indexing vectors by Euclidean (L2), inner product, or cosine distance, and supports vectors up to 16,383 dimensions.
The architecture supports transactional operations, meaning that inserting, updating, and deleting vector data is immediately reflected in the index. This feature is integrated into MySQL's default storage engine, allowing for seamless interaction with queries, including JOIN and WHERE clauses.
