Introduction to CQRS — In MicroservicesCategory: Database, Security, Data
Are you dealing with an application that involves complex business logic? The problem is that as applications become more complex, the handling of detailed queries and validation rules also grows in complexity.
In that regard, queries are methods that are only able to read and return data without modifying it.
Another key benefit of using CQRS in microservices has to do with the ability to scale read and write services independently.
Keep in mind that, in complex applications with multiple bounded contexts, nothing prevents you from implementing the CRUD data model in some contexts, and the CQRS pattern in others, leveraging the strengths of each architecture.
