PublisherCreatedEvent

PublisherCreatedEvent is a domain event used in event-driven architectures to indicate that a publisher entity has been created within a system. It is typically produced by the service responsible for managing publishers and consumed by downstream services that need to react to the creation, such as analytics, auditing, or notification components.

The event conveys essential information about the new publisher and is designed to be immutable once published. Commonly included fields are a publisherId, a human-readable name, an owner or accountId, a creation timestamp, and contextual metadata such as tenantId or sourceService. Additional fields may capture contact details, status, and any initial configuration attributes necessary to initialize downstream processes. The exact schema is often versioned to support evolution without breaking existing consumers.

In practice, a PublisherCreatedEvent is published to an event bus or message broker using at-least-once delivery semantics, ensuring reliable propagation to subscribed services. Consumers typically use the event to update read models, trigger onboarding workflows, emit audit logs, or start notification sequences. Idempotency handling is important to avoid duplicate processing if the same event is delivered more than once.

Related concepts include other publisher lifecycle events such as PublisherUpdatedEvent and PublisherDeletedEvent, as well as broader patterns like event sourcing and CQRS. Design considerations emphasize clear naming, stable payload schemas, backward compatibility, and appropriate access controls to protect sensitive publisher information.
