Ruvector Server

High-performance REST API server for Ruvector vector databases.

ruvector-server provides a production-ready HTTP API built on Axum with CORS support, compression, and OpenAPI documentation. Exposes full Ruvector functionality via RESTful endpoints. Part of the Ruvector ecosystem.

Why Ruvector Server?

• Fast: Built on Axum and Tokio for high throughput
• Production Ready: CORS, compression, tracing built-in
• RESTful API: Standard HTTP endpoints for all operations
• OpenAPI: Auto-generated API documentation
• Multi-Collection: Support multiple vector collections

Features

Core Capabilities

• Vector CRUD: Insert, get, update, delete vectors
• Search API: k-NN search with filtering
• Batch Operations: Bulk insert and search
• Collection Management: Create and manage collections
• Health Checks: Liveness and readiness probes

Advanced Features

• CORS Support: Configurable cross-origin requests
• Compression: GZIP response compression
• Tracing: Request tracing with tower-http
• Rate Limiting: Request rate limiting (planned)
• Authentication: API key auth (planned)

Installation

Add ruvector-server to your Cargo.toml:

[dependencies]
ruvector-server = "0.1.1"

Quick Start

Start Server

use ruvector_server::{Server, ServerConfig};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Configure server
    let config = ServerConfig {
        host: "0.0.0.0".to_string(),
        port: 8080,
        cors_origins: vec!["*".to_string()],
        enable_compression: true,
        ..Default::default()
    };

    // Create and start server
    let server = Server::new(config)?;
    server.run().await?;

    Ok(())
}
