How do I define the identity of an aggregate?

You use the #[Identifier] attribute on the property that holds the unique ID. Ecotone can then automatically map command properties to this identifier.

Why are aggregate factory methods static?

Static methods marked with #[CommandHandler] act as constructors for new aggregates, allowing Ecotone to instantiate the object from a creation command.

What is the difference between state-stored and event-sourced aggregates in Ecotone?

State-stored aggregates persist the current snapshot of an object to a database, whereas event-sourced aggregates store a sequence of events and reconstruct the state by replaying them.

What is the rule for EventSourcingHandler methods?

These methods must be side-effect-free; they should only be used to assign state to the aggregate based on the event data, never to trigger external logic.

API 개발

Implements Domain-Driven Design aggregates with state-stored or event-sourced persistence using the Ecotone Framework.

This skill provides specialized guidance for building robust domain models within the Ecotone Framework. It supports both traditional state-stored aggregates and event-sourced variants, offering patterns for command handler wiring, identity management, and lifecycle factory methods. By automating boilerplate for aggregate repositories and identifier mapping, it allows developers to focus on core business logic while maintaining clean DDD boundaries and architectural consistency.
