CQRS Implementation

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

Use this skill when

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

Do not use this skill when

The domain is simple and CRUD is sufficient
You cannot operate separate read/write models
Strong immediate consistency is required everywhere

Instructions

Identify read/write workloads and consistency needs.
Define command and query models with clear boundaries.
Implement read model projections and synchronization.
Validate performance, recovery, and failure modes.
If detailed patterns are required, open
