MariaDB vs Alopex DB

MariaDB Server storage engines, MariaDB Galera Cluster and MariaDB Vector, compared with Alopex DB.

Updated: Oct 15, 2026

What MariaDB is

MariaDB Server is an open source relational database built by the original developers of MySQL. It is a community-developed fork of MySQL, designed as a drop-in replacement, and is licensed under GPLv2.

How it works

  • Storage engines: a wide choice of storage engines and plugins.
  • MariaDB Galera Cluster: a virtually synchronous multi-primary cluster where any node can read and write.
  • MariaDB Vector: a vector type and vector index that use a modified HNSW for nearest-neighbor search.

Main features

  • A long history of SQL tooling and know-how.
  • GIS and JSON features.
  • AI-generated vectors stored and searched alongside relational data.

Limits

MariaDB Galera Cluster is Linux-only and supports only the InnoDB storage engine. MariaDB Server runs as a server separate from the application.

How it differs from Alopex DB

Both handle SQL and vector search in one database.

Alopex DB is a SQL database written in Rust that runs inside your application process. MariaDB Server starts with standing up a server; Alopex DB starts in the same process as your app and moves to a server, then to a Raft-replicated cluster, with the same SQL.

Before you stand up a server, run SQL and vector search inside your app with Alopex DB. The quickstart gets you there.
