Overview
CQRS suggests using different models for updating data (Commands) and reading data (Queries). This allows each model to be optimized independently for performance, scalability, and security.
How it Works
- Commands: Focus on business logic and validation. They change the state but don't return data.
- Queries: Focus on fast data retrieval. They return data but don't change the state.
Benefits
- Scalability: Read and write workloads can be scaled independently.
- Performance: The read model can be denormalized and optimized for specific UI views.
