HelixDB

HelixDB is a graph-vector database built for performance and simplicity.

Overview

HelixDB is a high-performance database system designed with a focus on developer experience and efficient data operations. Built in Rust and powered by LMDB as its storage engine, it combines the reliability of a proven storage layer with modern features tailored for AI and vector-based applications.

We are currently using LMDB via Heed, a rust wrapper built by the amazing team over at Meilisearch.

Key Features

• Fast & Efficient: Built for performance with lightning-fast startup times and millisecond query latency
• Vector-First: Native support for vector data types, making it ideal for RAG (Retrieval Augmented Generation) and AI applications
• Developer Friendly: Intuitive query language with built-in type checking and easy-to-use build tools
• Reliable Storage: Powered by LMDB (Lightning Memory-Mapped Database) for robust and efficient data persistence
• ACID Compliant: Ensures data integrity and consistency
• Managed Service: Available as a fully managed cloud service for simplified operations

Getting Started

Helix CLI

The Helix CLI tool can be used to check, compile and deploy Helix locally.

1. Install CLI

   curl -sSL "https://install.helix-db.com" | bash

2. Install Helix

   helix install

3. Setup

   helix init --path <path-to-create-files-at>

4. Write queries

   Write your schema and queries in the newly created .hx files. Head over to our GitHub for more information about writing queries

5. Check your queries (optional)

   cd <path-to-your-project>
   helix check

6. Deploy your queries

   cd <path-to-your-project>
   helix deploy --local

Other commands:

• helix instances to see your local instances.
• helix stop <instance-id> to stop your local instances.
• helix stop --all to stop all your local instances.
• helix start <instance-id> to start your local instances.

Roadmap

Our current focus areas include:

• Expanding vector data type capabilities for AI/ML applications
• Enhancing the query language with robust type checking
• Improving build tools and developer experience
• Implementing an easy-to-use testing system via CLI
• Optimizing performance for core operations
