What is Segregation?
Segregation refers to the act of separating or dividing into distinct parts. In CQRS, segregation is applied to separate the concerns of reading and writing data.
- By segregating these concerns, CQRS allows each part of the system to be optimized for its specific purpose.
- For example, the write model can be optimized for consistency and transactional integrity, while the read model can be optimized for performance and scalability.
Full Form of CQRS
CQRS stands for Command Query Responsibility Segregation. CQRS is a software architectural pattern that separates the operations that read data (queries) from the operations that modify data (commands) into different models.
- With CQRS, you have separate models for reads and writes, each optimized for its specific purpose.
- This separation allows you to scale and optimize each model independently, as they have different requirements.
- For example, the read model can be optimized for fast and efficient queries, while the write model can focus on ensuring data consistency and integrity.
