You can separate commands and queries by implementing CQRS patterns, which decouple state-changing operations from data retrieval. This allows your read and write models to scale independently and optimize performance for high-throughput workloads.

The best way to synchronize read and write models in event-sourced systems is through event-driven projections. Projectors handle read-model denormalization, ensuring faster queries by updating the read model whenever the write model changes.

To set up a minimal CQRS architecture, define a Command, a Query, and a simple read model. You then dispatch commands and retrieve queries through separate service buses, ensuring clear responsibilities for each handler.

You need CQRS for high-throughput write workloads when your application requires scalable, maintainable architectures. It is particularly useful when you must optimize complex read workloads and decouple them from heavy state-changing operations.

Yes, CQRS requires distinct command handlers and query handlers to enforce the separation of state-changing operations from data retrieval. This clear responsibility boundary is essential for maintaining scalable and optimized architectures.

Event-driven projections are used for read-model denormalization to enable faster queries. By projecting events into a dedicated read model, you avoid complex joins during retrieval and optimize performance for complex read workloads.
