Command-Query Responsibility Segregation (CQRS)
Apply the CQRS pattern to separate read and write operations in your application using RabbitMQ. Improve scalability and performance for data-intensive systems.
What is CQRS?
Ever wished your application could handle tons of writes and reads without slowing down? That's where CQRS comes in! It stands for Command-Query Responsibility Segregation.
CQRS is an architectural pattern that separates the operations for reading data from the operations for updating data. Think of it as having two specialized teams: one for taking orders and one for answering questions.
Understanding Commands
The "Command" side handles all requests that change the state of your application. These are actions like "CreateProduct", "UpdateOrderStatus", or "AddUser".
- Commands are imperative: They tell the system to do something specific.
- Commands are processed: They go through handlers that validate and execute the requested change.
- Commands often trigger events: After a command is successfully processed, an event might be published.
