SCaLE X 2025 – Boosting MySQL with Vector Search: Introducing the MyVector Plugin

As the demand for vector databases and Generative AI continues to rise, integrating vector storage and search capabilities into traditional databases has become increasingly important. This session introduces the MyVector Plugin, a project that brings native vector storage and similarity search to MySQL. Unlike PostgreSQL, which offers interfaces for adding new data types and index methods, MySQL lacks such extensibility. However, by utilizing MySQL’s server component plugin and UDF, the MyVector Plugin successfully adds a fully functional vector search feature within the existing MySQL + InnoDB infrastructure, eliminating the need for a separate vector database. The session explains the technical aspects of integrating vector support into MySQL, the challenges posed by its architecture, and real-world use cases that showcase the advantages of combining vector search with MySQL’s robust features. Attendees will leave with practical insights on how to add vector search capabilities to their MySQL systems.
