Event catalogs and schemas
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
build an event catalog that consumers can trust.
Planned topics
- Catalog entry: name, owner, description, schema, example, delivery guarantees, consumers, status.
- A schema (JSON Schema, Avro, or Protobuf; choose by tooling) is stored in a registry, not in someone's head.
- Events carry business facts at a useful level, not mirrored table rows.
- Consumers register themselves so the owner knows who a change affects.
Draft outline details
Demonstration
a catalog entry for OrderPlaced with fields (orderId, customerId, lines, totals, placedAt), schema location, consumers (fulfillment, finance, CRM sync), and delivery guarantee at-least-once.
