Messaging & Event Systems

Temporal workflows orchestrate long-running processes and activities with retries and signals to coordinate cross-service communication. This approach provides durable execution for complex business processes across distributed services.

Event sourcing captures state changes as a sequence of events, while CQRS separates read and write models. Together with sagas, these event-driven patterns coordinate complex business processes across distributed systems.

NATS pub/sub and JetStream integration provides publish-subscribe messaging with durable streams for distributed systems. Set up a local NATS workspace and run a sample order event workflow to observe publish/subscribe and durable orchestrations.

Yes, the messaging and event-driven architecture coordinates both real-time event processing and durable workflow orchestration. It applies across NATS pub/sub, Temporal workflows, and event-sourcing scenarios to unify cross-service communication.

Saga patterns coordinate complex business processes across distributed services when you need event-driven compensation and rollback. Use sagas with event sourcing and CQRS to avoid error-prone direct service-to-service communication at scale.

Coordinating distributed messaging and event-driven patterns across services is error-prone and hard to scale without unified orchestration. Applying consistent patterns across NATS pub/sub, Temporal workflows, and event sourcing reduces these coordination failures.
