Command Query Responsibility Segregation
CQRS, or Command Query Responsibility Segregation, is a design pattern used in software engineering that separates the responsibility for handling commands (write operations) from the responsibility for handling queries (read operations) in an application.
The Fractal Framework includes a powerful CQRS system that enables developers to implement the CQRS pattern in their applications. With Fractal CQRS, commands and queries are defined as separate concepts, with dedicated handlers for each. This separation of concerns makes it easier to reason about the application's behavior and to ensure that each operation is handled in the appropriate way.
One of the key benefits of using the CQRS pattern is that it can help to improve performance and scalability in an application. By separating the read and write operations, it is possible to optimize each operation independently, without affecting the other. For example, query handlers can be optimized for performance, while command handlers can be optimized for reliability and consistency.
The Fractal Framework's CQRS system also includes support for event sourcing, which is a technique for capturing the state of an application as a series of events. With event sourcing, it is possible to track changes to an application's state over time, which can help to improve auditability and ensure data consistency.
By using the CQRS pattern and the Fractal Framework's powerful CQRS system, developers can build high-performance, scalable, and reliable applications that are optimized for both read and write operations.
