SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Easily structure software systems to separate commands and queries, improving scalability and maintainability.

Core Features & Use Cases

  • Separate command and query models to optimize performance.
  • Projections and read-model synchronization for fast reads.
  • Event-sourced workflows enabling auditability and replay.

Quick Start

Create a baseline CQRS setup with separate read and write models and a simple event-driven example.

FAQPage Schema
What is CQRS and how does separating command and query models improve scalability?▼

CQRS separates command and query responsibilities to optimize read and write performance independently. By splitting these models, systems achieve scalable querying and maintainability, especially across CRUD-heavy, reporting, and analytics workloads.

How do I implement CQRS with event-sourced workflows for auditability?▼

Implement CQRS using an event store to capture write-model changes as events, enabling auditability and replay. Projections then update read models from these events, ensuring synchronized and fast query responses.

When should I use CQRS architecture for my system design?▼

Use CQRS architecture for systems requiring separate write and read models, event-driven updates, and scalable querying. It is best suited for CRUD-heavy applications, reporting, and analytics workloads where read optimization is critical.

What's the best way to synchronize read models with a command bus in CQRS?▼

Synchronize read models by routing commands through a command bus to the write model, then applying projections driven by an event store. This event-driven update mechanism keeps the read model updated for fast querying.

Does CQRS require event sourcing to handle command and query buses?▼

CQRS does not strictly require event sourcing to implement command and query buses, but combining them enables event-driven updates, read model synchronization, and replayable auditability for scalable architectures.

What are the limitations of using CQRS for read and write model separation?▼

CQRS limitations include increased architectural complexity and eventual consistency between write and read models. Projections and event-driven synchronization add overhead, making it less suitable for simple CRUD systems.
