Introduction Command Query Responsibility Segregation (CQRS) is a design pattern that decouples read operations (queries) from write operations (commands) into distinct pipelines. By isolating these responsibilities, CQRS enables scalable, maintainab...
Introdução O Command Query Responsibility Segregation (CQRS) é um padrão de design que separa operações de leitura (consultas) e escrita (comandos) em pipelines distintos. Ao isolar essas responsabilidades, o CQRS permite sistemas escaláveis e de fác...
💡 This article was created by first drafting with Cline + Claude 3.5 Sonnet based on my ideas, and then using Cline to iteratively refine and edit specific sections. Unlike pasting the entire text on the web for editing, this approach allowed me to ...
Recap In Part 2 of this series, I built on foundational concepts and dove into a practical implementation of a simple account management system, using both a conventional CRUD approach as well as an Event Sourcing approach. In this post, I will expan...
배경 CQRS(Command Query Responsibility Segregation) Pattern은 명령(Command)과 조회(Query)를 분리하여 각각 독립적으로 최적화할 수 있는 강력한 아키텍처 패턴이다. 이를 통해 시스템의 확장성과 유지보수성을 높일 수 있다. CQRS에서 명령을 처리하는 과정에서 Command Bus라는 개념이 등장하는데, 많은 자료에서 이를 비동기 방식으로 처리하는 예시를 주로 다루고 있다. 그러나 반드시 비동...
Introduction The first time this term appeared in Software Engineering lexicons was all the way back in 1997. It appeared in the book "Object-Oriented Software Construction" by Bertrand Meyer. At this time it was known as CQS (Command Query Separatio...
I'm currently experimenting with rewriting the way domains are described in Sekiban, Event Sourcing and CQRS Framework, to be simpler and more flexible. I've been writing a variety of verification code for this. Over the past two and a half years, I'...
Introduction Distributed systems are all the rage these days! With system design gaining traction in the software world, everyone is eager to learn and implement distributed systems. They (Distributed Systems) undoubtedly have their merits and provid...
Esta es la cuarta parte de una serie que comenzó llamándose “Arquitectura Hexagonal con Java y Spring”. En esta nueva entrega vamos a hablar de cómo una decisión que tomamos en la entrega anterior puede ocasionar que no cumplamos con uno de los princ...
When building complex systems, managing the codebase can become challenging as your application grows. One common issue developers face is the blurring of responsibilities within classes, where both reading and modifying data are handled together. Th...
