On This Lesson 4 topics

This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.

In this lesson

assign exactly one owner to every event, including across organizations.

Planned topics

  • The owner is the system of record for the fact: the system that decides it happened.
  • The owner defines the schema, publishes, and handles change; consumers do not publish look-alike events.
  • Cross-organization events (carrier, marketplace) need an agreement on who owns the contract.
  • Two owners for one event means conflicting versions soon.
