Introduction As software systems grow in complexity, the need for scalable and maintainable architectures becomes paramount. Two powerful patterns that address these needs are Command Query Responsibility Segregation (CQRS) and Event Sourcing. By leveraging these patterns, along with reactive principles, you can build systems that are highly responsive, resilient, and flexible. In this article, we will explore the concepts of CQRS and Event Sourcing, and provide detailed examples of how to implement them in a distributed system using Java and Spring Boot. Understanding CQRS What is CQRS? CQRS stands for Command Query Responsibility Segregation. It is a design pattern that…
