ShowMeYourCodeYouTube/cqrs-and-event-sourcing-in-kotlin

This system is a demonstration of modern software architecture patterns, specifically Command Query Responsibility Segregation (CQRS) and Event Sourcing, implemented in Kotlin with Spring Boot. It provides separate command and query models for managing product data, utilizing distinct repositories for write and read operations. The codebase includes both in-memory and persistent implementations, accompanied by integration tests to validate the behavior of these architectural components.
