What is the main benefit of using this CQRS skill?

It helps you separate read and write concerns, allowing you to optimize and scale each model independently for better performance.

When should I use CQRS instead of a standard CRUD pattern?

CQRS is recommended for complex domains where the read and write logic differs significantly, or when you need to optimize query performance across multiple data sources.

Does this skill support event sourcing?

Yes, the skill includes patterns for event stores, uncommitted events, and projectors which form the foundation of event-sourced systems.

Can this skill be used with frameworks other than FastAPI?

Yes. While the included templates feature FastAPI integration, the core Command and Query bus logic is framework-agnostic and can be applied to any Python backend.

API開発

Implements Command Query Responsibility Segregation (CQRS) to build highly scalable, performant, and maintainable backend architectures.

概要

This skill provides a comprehensive framework for implementing CQRS patterns within your applications, enabling the clean separation of data modification (Commands) from data retrieval (Queries). It offers standardized Python templates for command buses, query handlers, and event-sourced system foundations, making it ideal for developers building complex systems that require independent scaling of read and write workloads or high-performance reporting capabilities. By decoupling these concerns, the skill helps reduce system complexity in large-scale applications and facilitates more flexible data modeling.
