There is a practical way to support eventual consistency in a DDD model. An Aggregate command method publishes a Domain Event that is in time delivered to one or more asynchronous subscribers:
- Rule: Use Eventual Consistency Outside the Boundary
- from Implementing Domain-Driven Design
- Publisher: Addison-Wesley Professional
- Released: February 2013
I thought that this type of technique (using reference by id and eventual consistency) was used only when considering different bounded context and not in different aggregates.
