Dynamic Consistency Boundaries
DCB lets you define consistency scopes per operation: a temporary bubble that holds only the data the transaction actually needs. so your architecture can evolve with the business instead of resisting it.
Move past the aggregate as the organizing unit of your event store
Retire snapshots: A workaround finally made unnecessary with DCB
Start with good-enough boundaries and refine them as the domain reveals itself
Tag events with multiple semantic labels instead of pinning them to a single aggregate ID
Pivot from customer-centric to account-centric (or anything else) without migrations or lost history
