What is the command and query responsibility segregation software architecture style?
If you are a software developer, you probably know that there are different ways to design and structure your applications. One of them is the command and query responsibility segregation (CQRS) software architecture style. In this article, you will learn what CQRS is, how it works, what benefits and challenges it offers, and when to use it.
-
Separate concerns:CQRS divides an application into two distinct parts, enhancing performance. Use different models for commands (data changes) and queries (data retrieval), optimizing each side to best suit your needs.
-
Communicate data freshness:When employing CQRS, ensure users are aware of data synchronization delays. Create materialized views or read replicas, and keep users informed about the currentness of the data to maintain trust.
