The application now exposes a GraphQL interface for managing contacts. Users can query individual or list contacts via the \contact\ and \listContacts\ queries, and perform create, update, and delete operations through the \addContact\, \updateContact\, and \deleteContact\ mutations. This new API layer bridges the existing CQRS protocol with a modern query language, enabling clients to fetch contact details and modify the contact list through a single, structured endpoint.

A new MQTT-based queue manager has been introduced, providing a concrete implementation of the QueueManager interface. Users can now utilize MQTT for message publishing and subscribing, with support for configurable topics and payloads. The implementation includes connection handling, message routing, and timeout management for MQTT operations.

The application now implements a Command Query Responsibility Segregation (CQRS) pattern, separating write and read operations. A new database command provides an in-memory storage layer for contacts. A gRPC server exposes the database operations, while a separate gRPC proxy handles read requests. A new GraphQL server is introduced, which utilizes a queue-based writer client to handle write operations asynchronously via MQTT, and a reader client to fetch data. The system also includes an MQTT broker configuration and a queue manager to facilitate the decoupled write path.

The project has been initialized as a Go module (github.com/racerxdl/go-cqrs-example) with Go 1.13. The setup introduces dependencies for CQRS and development tools, including MQTT client (eclipse/paho.mqtt.golang), GraphQL server (graphql-go/graphql, graphql-go/handler), Protobuf (golang/protobuf), and MongoDB driver (go.mongodb.org/mongo-driver).
