SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams architect scalable systems by separating write and read responsibilities using CQRS, enabling independent optimization and evolution of data models.

Core Features & Use Cases

  • Separate Command and Query models to handle state changes and data retrieval efficiently.
  • Event-driven persistence and read-model projections for fast queries.
  • Use Case: When building an order management system that processes commands (create/cancel orders) and serves read-optimized views (order histories).

Quick Start

Create a basic CQRS skeleton with command and query buses, and a read model projection from events to demonstrate end-to-end flow.

FAQPage Schema
How do I separate read and write models for scalable system architectures?

You can separate models by implementing CQRS with distinct command handlers for state changes and query handlers for optimized data retrieval, enabling independent scaling and evolution of read and write data structures.

What is the CQRS pattern and when do I need it for event-sourced systems?

The CQRS pattern separates command and query models, using event-driven persistence and projections to update read models. You need it for event-sourced systems requiring optimized queries, complex workflows, and independent read/write data models.

How do I set up a basic CQRS skeleton with command and query buses?

Set up a CQRS skeleton by configuring a bus-based dispatch mechanism for commands and queries, then implementing a read model projection from events to demonstrate the end-to-end flow of state changes and data retrieval.

Does CQRS work for order management systems processing create and cancel commands?

CQRS works well for order management systems, efficiently processing commands like create or cancel orders while serving read-optimized views such as order histories through dedicated query handlers and read model projections.

Why use independent read and write data models instead of a single unified model?

Independent read and write models enable separate optimization of queries and state changes, preventing complex workflows from degrading read performance while allowing event-driven persistence to build fast, specialized read-model projections.

When should I not use CQRS to decompose reads and writes?

Avoid using CQRS to decompose reads and writes in simple applications where a unified data model suffices, as introducing command buses, query handlers, and event projections adds unnecessary architectural complexity.
