Command-Query Responsibility Segregation is an architectural style for developing applications that split the Domain Model in Read and Write operations in order to maximize semantics, performance, and scalability. What are all the benefits of CQRS? What are the drawbacks? In which cases does it worth applying it? How does it relate to Hexagonal Architecture? How do we properly implement the Write Model and Read Models? How do we keep in sync both sides? What are the following steps to move towards Event Sourcing? This book will answer all these questions and many more, guided through lots of practical examples. Brought to you by the same authors behind "Domain-Driven Design in PHP".

Clear and concise explanation of CQRS

4 stars

A thorough and easy-to-follow explanation of the composition and tradeoffs of CQRS systems. There is one chapter about Event Sourcing which provides the theoretical and practical contrasts between the two approaches.

This is a code-heavy book and the code is written in PHP, but it's pretty clear and should be easy to translate to other languages.

Having at least a minimal understanding of Domain Driven Design would be helpful before reading this book.
