Dynamo - Dynamic Routing System

​
Overview

Dynamo is an open-source dynamic routing system designed for payment processing. It intelligently routes payments to different processors based on real-time metrics, helping to optimize payment flows and increase transaction success rates.

​
Why Dynamo?

  • 💸 Increase Payment Success: Automatically route to the best-performing processors
  • 📊 Data-Driven Decisions: Make routing choices based on real performance metrics
  • 🌐 Multi-tenant Support: Isolate routing data between different merchants
  • ⚡ High Performance: Built with Rust for maximum efficiency and reliability
  • 🔄 Multiple Routing Strategies: Choose from success-rate, elimination, or contract-based routing

Quick Start

​
Local Setup

# Clone the repository
git clone https://github.com/yourusername/dynamo.git
cd dynamo

# Configure Redis
# Make sure Redis is running on localhost:6379 or update the config file

# Build the core service
cargo build --release

# Run with development configuration
./target/release/dynamo

​
Docker Setup

# Clone the repository
git clone https://github.com/yourusername/dynamo.git
cd dynamo

# Build the Docker image
docker build -t dynamo:latest .

# Run with default configuration
docker run -p 8000:8000 -p 9000:9000 dynamo:latest

# Run with custom configuration
docker run -p 8000:8000 -p 9000:9000 -v $(pwd)/config:/app/config dynamo:latest

​
Usage Examples

​
Success Rate Based Routing

# Make a routing decision based on success rates
grpcurl -d '{"id": "merchant1", "params": "card", "labels": ["stripe", "adyen"], "config": {"min_aggregates_size": 5, "default_success_rate": 100}}' \
  -plaintext localhost:8000 success_rate.SuccessRateCalculator/FetchSuccessRate

​
Update Payment Results

# Update success rate data with payment results
grpcurl -d '{"id": "merchant1", "params": "card", "labels_with_status": [{"label": "stripe", "status": true}], "config": {"max_aggregates_size": 10, "current_block_threshold": {"max_total_count": 5}}}' \
  -plaintext localhost:8000 success_rate.SuccessRateCalculator/UpdateSuccessRateWindow
For more examples, see our Examples Documentation.

Project Structure

Dynamo consists of two main components:
  • dynamo: Core routing service with GRPC/HTTP APIs
  • procesmo: WebAssembly module for data processing and visualization
The project uses a workspace structure: 
crates/
├── dynamo/         # Main routing service
└── procesmo/       # WebAssembly data processing module
