Quick Reference
CQRS: Separate Command (write) and Query (read) models. Commands mutate state, return void/ID. Queries return data, never mutate. Read models optimized for queries. Can use different databases. Often paired with Event Sourcing. Not needed for simple CRUD.
Use When
- Complex domain logic
- Different read/write scaling needs
- Multiple read model representations
- Event sourcing systems
Skip When
- Simple CRUD applications
- Same read/write patterns
- Small teams learning DDD
