CQRS (Command Query Responsibility Segregation)

CQRS is a pattern that separates read and update operations for a data store. Instead of using a single model for both, you have a Command Model (Write) and a Query Model (Read).

When to Use

• High Disparity: Read load is 1000x higher than Write load (or vice versa).
• Complex UI: The UI needs data shaped differently than the way it's stored (e.g., Dashboard aggregation).
• Event Sourcing: CQRS is almost mandatory for Event Sourcing.
