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 resources/implementation-playbook.md.
