CQRS

← Back to Event-Driven Architecture

Command Query Responsibility Segregation. Separate read and write models. Commands mutate state through one model optimized for writes; queries read state through a different model optimized for reads. Enables independent scaling and optimization of each side.

Key Properties

• Separate Read Write Models
• Eventual Consistency Between Models
• Independent Scaling

Related

• Event Sourcing (commonly paired)
• Data Ownership (per-model data stores)
