HelixDB Docs

A high-performance graph-vector database with its own query language designed for traversing and manipulating graph and vector data efficiently.

Introduction

HelixDB

HelixDB can be used locally by installing the HelixCLI.

Installation

In this short example, you will create a HelixDB instance, write a schema and queries, and run basic queries using the Python SDK.

What is HelixQL?

These operations allow you to add new elements to your graph.

Create Operations

These operations serve as starting points for your graph traversals.

Select Operations

These operations allow you to search for vectors in Helix. Searching is done using cosine similarity.
