What is CQRS (Command and Query Responsibility Segregation) Pattern in Microservices Architecture?

Why use CQRS Pattern? How does CQRS Pattern improves scalability of your Microservice architecture.

Hello folks, if you are working on Microservice architecture and wondering what is CQRS (Command and Query Responsibility Segregation) Pattern and how it can improve your Microservices architecture then you have come to the right place.

In the last few articles I have talked about essential Microservice design patterns like Event Sourcing, SAGA, Database Per Microservices, API Gateway, Circuit-Breaker and also shared best practices to design Microservices and in this article, I will tell you everything about CQRS pattern which I know like what it is, how does it work, what are pros and cons of this pattern and also how does it impact your Microservices architecture.

In last few years, Microservices architecture has gained immense popularity due to its ability to enable scalability, maintainability, and agility in modern application development.

However, managing the complexity and coordination of microservices can be challenging. This is where the CQRS (Command Query Responsibility Segregation) pattern comes into play.
