Kafka for Developers - Data Contracts Using Schema Registry - Introduction to Logical Types in AVRO

This lecture introduces logical types in Avro, which are used to represent data types like decimals, UUIDs, dates, timestamps, and time. It explains how logical types are defined in Avro schemas with additional attributes and provides examples, particularly focusing on the decimal type. The lecture also covers other logical types such as UUID, date, time, timestamp, and duration, detailing their attributes and usage. The importance of precision and scale in representing decimal values is highlighted, along with the representation of time and timestamp with millisecond and microsecond precision. The lecture concludes by emphasizing the need for practical knowledge in applying these logical types.

How does Avro handle logical types in terms of schema definition?

What does the duration logical type represent in Avro?
