Vector search and storage are being added to MySQL by PlanetScale, enabling users to utilize the platform for AI use cases without needing a separate tool. Vectors are one-dimensional arrays of real number values representing attributes or dimensions, useful in applications like machine learning where vectors are used to transform arbitrary data into a uniform numerical representation. The addition of vector storage and search will allow MySQL users to efficiently traverse graphs of vectors, quickly presenting users with similar results, reducing the need for separate databases or additional operational burden. PlanetScale is maintaining a fork of MySQL to add vector types and indexes, with plans to release new packages and containers for testing and development locally, and will automatically gain vector storage and retrieval capabilities for current customers upon launch.
