Rinha de Backend 2025 - Quarkus(native) with Redis

This project implements a resilient backend for the Rinha de Backend 2025 challenge.
It handles payment processing with limited resources, managing a high volume of requests even with minimal infrastructure.
The main focus is on building a robust and fault-tolerant system that can operate reliably under constrained conditions.

The backend is built using Quarkus, with native compilation via GraalVM, Java 21, and Redis for distributed caching.

• Language: Java 21
• Framework: Quarkus 3 (with Vert.x)
• Storage / Queue: Redis
• Compilation: GraalVM (native)
• Containerization: Docker
• Load Balancer: Nginx

• Resilient payment processing
• Automatic fallback between gateways
• Integrated services health checks
• Redis queue system with asynchronous workers
• Distributed cache with Redis

Follow the steps below to run the project locally:

1. Build the producer and consumer modules with native GraalVM compilation:

./mvnw clean package

2. Start the full environment with Docker Compose:

docker compose up
