MariaDB

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
