Problem

How do modules communicate with each other?

Solution

Modules communicate by publishing and subscribing to events

Relationship with transaction patterns:

  • Transaction-per-operation: event subscriber is invoked in the publisher’s transaction
  • Transaction-per-module: event subscriber is invoked in a different transaction, publisher will typically use the Transaction outbox pattern to ensure that the publisher atomically updates its database and sends a message.
