cqrs eventsourcing

cqrs-notes.md

1. Command: write, single handler, Event: past sense, many handlers
2. Domain Events: Inside events, Integration events: Outside events (Outside from service, service boundrary)
3. External Events == Integration Events != Domain Events
4. Anti pattern CRUD sourcing: EntryUpdated, ProductCreated, ProductDeleted, etc. (use business value event: InventoryAdjusted, PriceIncreased. etc)
5. Propery Sourcing: events like UserEmailChanged, UserNameChanged, etc.
