DashVector

DashVector is a fully-managed vectorDB service that supports high-dimension dense and sparse vectors, real-time insertion and filtered search. It is built to scale automatically and can adapt to different application requirements.

This document demonstrates to leverage DashVector within the LangChain ecosystem. In particular, it shows how to install DashVector, and how to use it as a VectorStore plugin in LangChain. It is broken into two parts: installation and setup, and then references to specific DashVector wrappers.

Installation and Setup

Install the Python SDK:

pip install dashvector

VectorStore

A DashVector Collection is wrapped as a familiar VectorStore for native usage within LangChain, which allows it to be readily used for various scenarios, such as semantic search or example selection.

You may import the vectorstore by:

from langchain.vectorstores import DashVector
