SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

CQRS provides a clear separation between the commands that mutate state and the queries that read state, enabling scalable architectures through specialized write and read models, event sourcing, and optimized query performance.

Core Features & Use Cases

  • Separation of concerns between write and read models to enable independent scaling.
  • Event-driven propagation of state changes to keep read models up-to-date with write-side events.
  • Read-model projections to support fast, denormalized queries and reporting in complex systems such as ecommerce orders or inventory.

Quick Start

Configure a CQRS-based service, publish a CreateOrder command to drive the write model, and query the Order views from the read model to validate results.

FAQPage Schema
What is CQRS and how does separating commands and queries improve scalability?▼

CQRS separates commands that mutate state from queries that read state, enabling scalable architectures by using distinct write and read models to optimize high-throughput processing and query performance independently.

How do I implement event sourcing with read model projections?▼

Implement event sourcing by publishing commands to mutate the write model, then use event-driven propagation to synchronize state changes into read-model projections for fast, denormalized queries.

When should I use CQRS and event sourcing in my architecture?▼

Use CQRS and event sourcing in systems requiring high-throughput command processing and optimized read performance, such as complex ecommerce order processing, inventory management, and reporting applications.

How do I configure a service to handle commands and query views separately?▼

Configure a CQRS-based service, publish a CreateOrder command to drive the write model, and query the Order views from the read model to validate the separated command and query results.

What is the difference between command handlers and query handlers?▼

Command handlers process state mutations by executing write operations, while query handlers fetch data from optimized read models, ensuring clear separation of concerns between independent scaling requirements.

Why does my read model get out of sync with the write model?▼

Read models stay synchronized through event-driven propagation of state changes, ensuring that every write-side event updates read-model projections to support fast, denormalized queries.
