CQRS + GraphQL: The Architecture That Improved API Performance by 35%

CQRS (Command Query Responsibility Segregation) is a pattern that separates read and write operations. Combined with GraphQL, it creates powerful, performant APIs.

Why CQRS?

Traditional CRUD APIs use the same model for reads and writes. This creates N+1 problems and forces compromises. CQRS lets you optimize each independently.

The GraphQL Gateway Pattern

Your GraphQL layer becomes a smart gateway that routes queries to read models and mutations to write models.

Implementation

The result: 35% API latency reduction and dramatically simpler domain models.
