!GitHub Stars(https://img.shields.io/github/stars/oovm/opencrab)

🚀 High-Performance Distributed Key-Value Store

Rusty-Docker Etcd is a Rust-implemented etcd server that provides distributed key-value storage functionality for the Rusty-Docker ecosystem. Designed for reliability, performance, and scalability, it enables distributed configuration management and service discovery for containerized applications.

✨ Key Features That Power Distributed Systems

📦 Distributed Key-Value Storage

Highly Available: Replicated data store with automatic failover
Consistent: Strong consistency guarantees using Raft consensus algorithm
Scalable: Horizontal scaling to handle increasing workloads
Durable: Persistent storage with write-ahead logging

🔄 Service Discovery

Dynamic Service Registration: Automatically register and discover services
Health Monitoring: Track service health and availability
Load Balancing: Distribute traffic across healthy service instances
Service Resolution: Resolve service names to network addresses

🔧 Configuration Management

Centralized Configuration: Store and manage configuration for distributed systems
Configuration Updates: Dynamic configuration changes with real-time propagation
Version Control: Track configuration history and rollback changes
Namespace Support: Isolate configurations for different applications or environments

📡 Event System

Change Notifications: Subscribe to key changes with event streams
Watch API: Monitor specific keys or directories for changes
Event History: Track and replay configuration changes
Filtering: Selective event notifications based on patterns

🔒 Security

Authentication: Secure access control with user authentication
Authorization: Fine-grained access control for keys and operations
TLS Support: Encrypted communication between clients and servers
Audit Logging: Track all operations for compliance and troubleshooting

📋 Core Components

Raft Consensus

Leader Election: Automatic leader election for consistency
Log Replication: Replicate operations across the cluster
Membership Management: Add or remove nodes from the cluster
Quorum-Based Decisions: Ensure data consistency with quorum

Key-Value Store

Hierarchical Namespace: Organize keys in a directory-like structure
Atomic Operations: Ensure consistency for complex operations
TTL Support: Automatic expiration of keys
Compactation: Maintain store efficiency with log compactation

API Server

gRPC API: High-performance, language-agnostic API
HTTP/JSON API: RESTful interface for simple integrations
Client Libraries: Official client libraries for multiple languages
Health Checks: Endpoints for monitoring cluster health

🛠️ Quick Start

Basic Usage

use docker_etcd::Client;

#[tokio::main]
async fn main() {
    // Create a client connection
    let client = Client::new(vec!["http://localhost:2379"]).await.unwrap();
    
    // Set a key-value pair
    client.put("config/database/url", "postgres://localhost:5432/mydb").await.unwrap();
    
    // Get a value
    let value = client.get("config/database/url").await.unwrap();
    println!("Database URL: {}", value);
    
    // Watch for changes
    let mut watcher = client.watch("config/").await.unwrap();
    while let Some(event) = watcher.next().await {
        println!("Config changed: {:?}", event);
    }
}
