Kafka for Developers - Data Contracts Using Schema Registry - Build a Coffee Order Schema Using AVRO

This lecture covers the creation of a schema for a coffee order service using Avro. It begins with an introduction to the schema and the tools used, such as Gradle and Maven. The process of creating an Avro schema is detailed, including defining fields like ID, name, and optional fields. The lecture explains how to handle complex types by abstracting them into separate schema files, and how to manage arrays and order line items. It also covers the use of enums and logical types in Avro schemas. The lecture concludes with a summary and a look at future steps for generating Avro classes.
