cqrs-implementation

实现 CQRS 模式的指南，用于分离读写模型和优化查询。

把命令(写)和查询(读)彻底分开，允许用不同的数据模型和存储来优化各自的性能，适合读多写少、复杂报表或事件溯源的系统。需要在系统要独立扩展读端、减少查询复杂度或提升可维护性时采用。特别之处是可以选择最合适的存储技术和异步同步策略，但同时要处理好最终一致性和额外的系统复杂度。

# CQRS Implementation

Comprehensive guide to implementing CQRS (Command Query Responsibility Segregation) patterns.

## When to Use This Skill

- Separating read and write concerns
- Scaling reads independently from writes
- Building event-sourced systems
- Optimizing complex query scenarios
- Different read/write data models needed
- High-performance reporting requirements

## Core Concepts
