This module allows Drupal to use MariaDB as a vector database for AI features, eliminating the need for separate external services. It leverages MariaDB's native vector data type and indexing to store and query AI embeddings directly within your existing database.
Native vector search for Drupal using MariaDB — no external services required.
This module enables MariaDB’s native VECTOR data type and indexing capabilities (available in MariaDB 11.7+) as a Vector Database (VDB) provider for the Drupal AI module. Since MariaDB is a drop-in replacement for MySQL and is widely used as Drupal’s primary database, vector embeddings can be stored and queried directly within the same database with full transactional support.
If your Drupal site already uses MariaDB, you can store your AI vectors in it by upgrading MariaDB to version 11.7 or later. If your site uses MySQL, you can replace it with MariaDB to enjoy the benefits of this module.
Features
- Native MariaDB Vector Support: Utilizes MariaDB's built-in VECTOR data type and specialized VECTOR indexes
- Multiple Distance Metrics: Support for Euclidean distance and Cosine similarity
- Optimized Performance: Leverages MariaDB's modified HNSW (Hierarchical Navigable Small Worlds) algorithm
- Seamless Integration: Works with the Drupal AI module and Search API
- No External Dependencies: No need for separate vector database services
- Operational Simplicity: No additional services, containers, or infrastructure layers
Post-Installation
- Create a Search API server using the AI Search backend
- Select "MariaDB vector DB" as the VDB provider
- Configure your embedding strategy and vector dimensions
- Create an index and add fields to the index
- Index your content
Your vector index is then ready for use with Drupal AI-powered features such as semantic search and RAG-based systems.
Additional Requirements
- Drupal 10.2+ or Drupal 11+
- MariaDB 11.7 or later (11.8 LTS recommended for GA support)
- PHP 8.1+
- PHP mysqli extension
- Drupal AI module
