Use Case 1: Registering and Querying a Schema for a Kafka Topic
When you integrate Apache Kafka into your enterprise, you should ask yourself the following types of questions:
What are the different events in a given Kafka topic?
What do I put into a given Kafka topic?
Do all Kafka events have a similar type of schema?
How do I parse and use the data in a given Kafka topic?
While Kafka topics do not have a schema, having an external store--a Schema Registry--that tracks this metadata helps to answer these questions. And
Schema Registry is not just a metastore for Kafka. Schema Registry is designed to be generic schema store for any type of entity or store, such as log files and similar objects.
