Kafka for Developers - Data Contracts Using Schema Registry - Build the DTOs for CoffeeOrderService

This lecture covers the development of a Restful service for a coffee order system. It begins with creating DTO classes for data transfer, utilizing Lombok annotations to minimize boilerplate code. The lecture then details the construction of Store and Address DTOs, followed by defining order line items and enums. The session concludes with a brief overview of bean validations and a preview of the next lecture on building a post endpoint.
