Foodie Project

This project, named "Foodie", is a demonstration of various concepts in software development, including Microservices with Spring Boot, Clean Architecture, Domain-Driven Design (DDD), SAGA, Outbox, Kafka, and Maven multi-module.

Overview

Foodie is a system that aims to provide a platform for food lovers to explore, discover, and order food. It consists of multiple microservices, each responsible for a specific aspect of the overall system. The project follows the principles of Hexagonal Clean Architecture and Domain-Driven Design to ensure a modular, scalable, and maintainable codebase.

High Level Architecture

Concepts Used

• Hexagonal Clean Architecture with Ports & Adapters.
• DDD (Domain-Driven Design)
• SAGA Pattern for distributed transaction and data consistency (process & rollback with compensating tx)
• Outbox Pattern for pulling Outbox table with scheduler (Saga Status)
  • Ensure idempotency using outbox in each service.
  • Prevent concurrency issues with optimistic locks & DB constraints.
  • Updating Saga & Order status for each operation.
• CQRS Pattern with Event Sourcing.
• Maven Multi-Module
• Kafka
• Kubernetes
