AI Summary (BLUF)

HelixDB is a unified database platform that combines graph, vector, KV, document, and relational data models to simplify AI application development by eliminating the need for multiple specialized databases and application layers. (HelixDB是一个统一的数据库平台,集成了图、向量、键值、文档和关系数据模型,通过消除对多个专用数据库和应用层的需求,简化AI应用开发。)

Introduction

HelixDB is a unified database platform designed to simplify the development of AI applications. It consolidates all essential backend components into a single system, eliminating the complexity of managing multiple specialized databases and application layers.

HelixDB 是一个统一的数据库平台,旨在简化 AI 应用程序的开发。它将所有必要的后端组件整合到一个单一系统中,消除了管理多个专用数据库和应用层的复杂性。

Traditionally, building applications that leverage AI, agents, or Retrieval-Augmented Generation (RAG) requires a fragmented architecture: a separate application database, a vector database for embeddings, a graph database for relationships, and complex application logic to orchestrate them all. HelixDB changes this paradigm.

传统上,构建利用 AI、智能体或检索增强生成(RAG)的应用程序需要一个分散的架构:一个单独的应用数据库、一个用于嵌入向量的向量数据库、一个用于关系的图数据库,以及用于协调所有这些组件的复杂应用逻辑。HelixDB 改变了这一范式。

With HelixDB, you can build the complete backend for any AI-powered application on one platform. Its core operates on a combined graph and vector data model, while also providing support for key-value, document, and relational data paradigms.

使用 HelixDB,您可以在一个平台上为任何 AI 驱动的应用程序构建完整的后端。其核心基于图与向量相结合的数据模型运行,同时也支持键值、文档和关系型数据范式。

Key Features

Built-in MCP Tools

HelixDB features built-in support for the Model Context Protocol (MCP), enabling your AI agents to dynamically discover data and navigate the graph structure. This allows agents to reason about data relationships directly, moving beyond simply generating human-readable queries for execution.

HelixDB 内置了对模型上下文协议(MCP)的支持,使您的 AI 智能体能够动态发现数据并遍历图结构。这使得智能体能够直接推理数据关系,而不仅仅是生成人类可读的查询来执行。

Built-in Embeddings

The platform includes native embedding capabilities. There is no need to pre-process and vectorize your text data using external services before ingestion. You can simply use the built-in Embed function to convert text into vectors directly within HelixDB.

该平台包含原生的嵌入功能。在数据入库前,无需使用外部服务对文本数据进行预处理和向量化。您可以直接在 HelixDB 内部使用内置的 Embed 函数将文本转换为向量。

Tooling for RAG

HelixDB is equipped with a comprehensive suite of search and traversal tools purpose-built for RAG applications. This includes:

  • Built-in vector search (向量搜索)
  • Keyword search (关键词搜索)
  • Graph traversals (图遍历)
    These can be combined in flexible ways to power sophisticated retrieval strategies.

HelixDB 配备了一套专为 RAG 应用程序构建的完整搜索和遍历工具集。这包括:

  • 内置向量搜索
  • 关键词搜索
  • 图遍历
    这些工具可以灵活组合,为复杂的检索策略提供动力。

Secure by Default

Security and privacy are foundational. HelixDB is private by default, and data access is strictly controlled. The only way to interact with your data is through pre-compiled HelixQL queries, providing a strong, query-level security model.

安全性和隐私性是基础。HelixDB 默认是私有的,数据访问受到严格控制。与您的数据交互的唯一方式是通过预编译的 HelixQL 查询,这提供了一个强大的、查询级别的安全模型。

Ultra-Low Latency

Built with performance in mind, HelixDB is implemented in Rust and utilizes LMDB as its high-performance storage engine. This combination delivers extremely low latency for both read and write operations, which is critical for responsive AI applications.

HelixDB 以性能为核心构建,采用 Rust 语言实现,并利用 LMDB 作为其高性能存储引擎。这种组合为读写操作提供了极低的延迟,这对于响应迅速的 AI 应用程序至关重要。

Type-Safe Queries

HelixQL, the query language of HelixDB, is 100% type-safe. This means queries are validated at compile time, catching errors early in the development cycle. It allows developers to build and deploy with confidence, knowing that their queries will execute correctly in production.

HelixQLHelixDB 的查询语言,它是 100% 类型安全的。这意味着查询在编译时就被验证,在开发周期早期就能捕获错误。它使开发人员能够充满信心地进行构建和部署,因为他们知道自己的查询在生产环境中将正确执行。

Getting Started

Helix CLI

The first step is to install the Helix Command Line Interface (CLI) tool, which allows you to deploy and manage HelixDB instances locally.

第一步是安装 Helix 命令行界面(CLI)工具,该工具允许您在本地部署和管理 HelixDB 实例。

Install CLI

You can install the CLI using the following command:

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

您可以使用以下命令安装 CLI:

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

Initialize a Project

Create a new directory for your project and initialize it with Helix.

mkdir <path-to-project> && cd <path-to-project>
helix init

为您的项目创建一个新目录,并使用 Helix 对其进行初始化。

mkdir <path-to-project> && cd <path-to-project>
helix init

Write Queries

Open the newly created .hx files to begin defining your data schema and queries. Visit our documentation for detailed guidance. Below is a basic example:

打开新创建的 .hx 文件,开始定义您的数据模式和查询。请访问我们的文档以获取详细指导。以下是一个基本示例:

N::User {
   INDEX name: String,
   age: U32
}

QUERY getUser(user_name: String) =>
   user <- N<User>({name: user_name})
   RETURN user

(Optional) Check Query Compilation

Validate that your HelixQL queries are syntactically and semantically correct.

helix check

验证您的 HelixQL 查询在语法和语义上是否正确。

helix check

Deploy Your Queries

Deploy your compiled queries to their corresponding API endpoints on a development instance.

helix push dev

将您编译好的查询部署到开发实例上对应的 API 端点。

helix push dev

Integrate with Your Application

Start calling your deployed queries using the official TypeScript or Python SDKs. Example using TypeScript:

使用官方的 TypeScript 或 Python SDK 开始调用您已部署的查询。使用 TypeScript 的示例如下:

import HelixDB from "helix-ts";

// Create a new HelixDB client
// The default port is 6969
const client = new HelixDB();

// Execute a mutation query
await client.query("addUser", {
  name: "John",
  age: 20,
});

// Execute a read query
const user = await client.query("getUser", {
  user_name: "John",
});

console.log(user);
