CRUD & Exposing Data
Kafka got the data into Postgres. Now the consumer needs its own REST surface so the data is actually usable by clients — closing the loop on the architecture from Module 04.
Learning objectives
- Beginner: Explain why CRUD read endpoints query a local database rather than reading directly from Kafka.
- Intermediate: Implement REST CRUD endpoints for data that originated as a consumed Kafka event.
- Advanced: Design the consumer's REST surface so it stays consistent with the producer's event schema as both evolve.
