VillageSQL Launches as an Extension-Focused MySQL Fork

"A new open-source project, VillageSQL, has been introduced as a tracking fork of MySQL aimed at expanding extensibility and addressing feature gaps increasingly relevant to AI and agent-based workloads. Announced by founder Dominic Preuss, VillageSQL Server for MySQL is positioned as a drop-in replacement that maintains compatibility with upstream MySQL while adding a structured extension framework. The alpha release is now available for experimentation."

"Unlike MySQL, which supports plugins, VillageSQL offers a more comprehensive extension model that allows users to package custom data types, functions, and eventually indexes into units that can be directly installed into the database engine. Extensions are deployed as external repositories or compiled dynamic libraries. Administrators can install them by placing the extension file into the designated directory and running an INSTALL EXTENSION SQL command."

"The launch takes place amid ongoing discussions about MySQL's role in modern development. Recently, innovation has primarily centered on PostgreSQL, known for its strong extension framework and community governance. Additionally, AI-driven workloads, particularly retrieval-augmented generation (RAG), have introduced new demands like vector search that standard MySQL distributions do not address. VillageSQL's roadmap includes support for vector indexing and optimized vector search. The initial alpha release ships with several example extensions, including support for UUIDs, network address types (IPv6 and MAC), cryptographic functions, complex numbers."

VillageSQL is an open-source tracking fork of MySQL that adds a structured extension framework while remaining compatible as a drop-in replacement. The project enables permissionless innovation by allowing packaging of custom data types, functions, and eventually indexes into installable extensions deployed as external repositories or compiled dynamic libraries. Administrators install extensions by placing files in a directory and running an INSTALL EXTENSION SQL command. The roadmap prioritizes vector indexing and optimized vector search to support AI-driven workloads such as retrieval-augmented generation (RAG). The alpha release includes example extensions for UUIDs, IPv6 and MAC addresses, cryptographic functions, complex numbers, and SQL-based AI prompting functions.
