Exploring Karapace—the Open Source Schema Registry for Apache Kafka®: Part 2—Apache Avro IDL, NOAA Tidal Example, POJOs, and Logical Types
This is the second part of our “Exploring Karapace—the Open Source Apache Kafka Schema Registry” blog series, where we continue to get up to speed with Platonic Forms (aka Schemas) in the form of Apache Avro, which is one of the Schema Types supported by Karapace.
