This page covers how to use the MariaDB ecosystem within LangChain. It is broken into two parts: installation and setup, and then references to specific PGVector wrappers.

​
Installation

  • Install c/c connector
on Debian, Ubuntu 
sudo apt install libmariadb3 libmariadb-dev
on CentOS, RHEL, Rocky Linux 
sudo yum install MariaDB-shared MariaDB-devel
  • Install the Python connector package with pip install mariadb

​
Setup

  1. The first step is to have a MariaDB 11.7.1 or later installed. The docker image is the easiest way to get started.

​
Wrappers

​
VectorStore

There exists a wrapper around MariaDB vector databases, allowing you to use it as a vectorstore, whether for semantic search or example selection. To import this vectorstore: 
from langchain_mariadb import MariaDBStore

​
Usage
