Axum API & User Consumer Workspace

ℹ️ Overview

A Proof of Concept (PoC) to evaluate Rust for production-ready microservices. The goal is to verify if the Rust ecosystem (Axum, Tokio, SQLx) is mature enough for real-world application development, focusing on performance, type safety, and developer experience.

🛠 Tech Stack

• Language: Rust
• Web Framework: Axum
• Database: MSSQL (via sqlx, tiberius)
• Messaging: Kafka (via rdkafka)
• gRPC: Tonic
• Cache: Redis
• Infra: Docker Compose

🚀 How to Run

1. Start All Servers

Start all services including the REST API, Kafka Consumer, and Infrastructure:

• REST API: :4000
• Kafka UI: :8080

cp crates/axum-api/.env.example crates/axum-api/.env
cp crates/user-consumer/.env.example crates/user-consumer/.env

docker compose up -d --build

2. Run k6 Benchmark

The benchmark suite tests the "User Registration" flow.
