Argon 🚀

The first MongoDB branching system with time travel. Git-like branching meets WAL architecture for enterprise MongoDB.

Argon is the first MongoDB database with Git-like time travel capabilities.

⚡ WAL-Powered Architecture - Experience instant branching (1ms) and query any point in history using our Write-Ahead Log implementation.

🎉 PRODUCTION READY - Complete time travel system with 37,905+ ops/sec performance.

⚡ Why Argon Changes Everything

Traditional database workflows are fundamentally broken: - Slow: Creating database copies takes hours or days - Expensive: Each environment needs complete data duplication
- Risky: No easy way to undo destructive operations - Limited: Can't query historical states or track changes over time

Argon revolutionizes this with production-ready WAL architecture:

# Enable time travel capabilities
export ENABLE_WAL=true

# Create projects with instant branching
argon projects create ecommerce

# Query your database from any point in time  
argon time-travel info --project ecommerce --branch main

# Safely preview restore operations
argon restore preview --project ecommerce --lsn 1500

# Real-time monitoring
argon metrics
argon status

🚀 Quick Start

Installation

# macOS (Homebrew)
brew install argon-lab/tap/argonctl

# Cross-platform (npm)  
npm install -g argonctl

# Python SDK
pip install argon-mongodb

# From Source
git clone https://github.com/argon-lab/argon
cd argon/cli && go build -o argon

60-Second Demo

# 1. Enable WAL mode
export ENABLE_WAL=true

# 2. Create your first project with time travel
argon projects create ecommerce
# ✅ Created project 'ecommerce' with time travel in 1.16ms

# 3. Use your app normally - all operations automatically logged
# ... your MongoDB operations run as usual ...
# Behind the scenes: Every operation stored in append-only WAL

# 4. Time travel to see data at any point
argon time-travel info --project ecommerce --time "1h ago"
# ✅ LSN Range: 1000-2500, Total Entries: 1500, <50ms query time

# 5. Create instant branches for safe experimentation
argon branches create experimental-features
# ✅ Branch created in 1.16ms with zero data copying

# 6. Preview restore operations before executing
argon restore preview --project ecommerce --lsn 1500
# ✅ Preview: 500 operations to discard, 3 collections affected

# 7. Safely restore to any point in history
argon restore reset --branch main --lsn 1500
# ✅ Branch reset to LSN 1500, 500 operations discarded safely

That's it! You now have production-ready Git-like branching and time travel for MongoDB.

🏗️ WAL Architecture

Argon implements a Write-Ahead Log (WAL) architecture inspired by Neon but designed specifically for MongoDB document databases:

┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
│   Application   │────▶│ WAL Interceptor │────▶│  MongoDB Store  │
│ (Unchanged API) │     │ (Transparent)   │     │ (LSN-indexed)   │
└─────────────────┘     └─────────────────┘     └─────────────────┘
                                │                         │
                                ▼                         ▼
                        ┌─────────────────┐     ┌─────────────────┐
                        │  Materializer   │◀────│ Branch Metadata │
                        │ (<50ms queries) │     │ (Lightweight)   │
                        └─────────────────┘     └─────────────────┘
                                │                         │
                                ▼                         ▼
                        ┌─────────────────┐     ┌─────────────────┐
                        │  Time Travel    │     │ Monitoring &    │
                        │  (Any LSN/Time) │     │ Metrics Engine  │
                        └─────────────────┘     └─────────────────┘

🛠️ Production-Ready SDKs

Go SDK (✅ Production Ready)

import "github.com/argon-lab/argon/pkg/walcli"

// Initialize services
services, _ := walcli.NewServices()

// Create projects and branches
project, _ := services.Projects.CreateProject("myapp")
projects, _ := services.Projects.ListProjects()

// Time travel queries
state, _ := services.TimeTravel.MaterializeAtLSN(branch, "users", 1500)
preview, _ := services.Restore.GetRestorePreview(branchID, targetLSN)

Python SDK (✅ Published)

# Install with pip
pip install argon-mongodb

# Basic usage
from argon import ArgonClient

client = ArgonClient()
project = client.create_project("ml-experiment")

# ML integrations
from argon.integrations import jupyter
jupyter.init_argon_notebook("ml-project")
jupyter.create_checkpoint("model_v1", "First working model")

JavaScript/Node.js (✅ Published)

# Install CLI globally
npm install -g argonctl

# Use in your Node.js application
const { exec } = require('child_process');
exec('argon projects list', (err, stdout) => {
  console.log('Projects:', stdout);
});

Zero-Friction Integration

// Before: Standard MongoDB connection
const { MongoClient } = require('mongodb');
const client = new MongoClient('mongodb://localhost:27017');

// After: Argon WAL (identical API, magical features)
process.env.ENABLE_WAL = 'true';
const client = new MongoClient('mongodb://localhost:27017');
// Now you have branching, time travel, and restore! 🎉

// Your existing MongoDB code works unchanged:
const db = client.db('myapp');
const users = db.collection('users');
await users.insertOne({ name: 'Alice', email: 'alice@example.com' });
// Behind the scenes: Operation logged to WAL with LSN 1001
