Confluent Schema Registry

Confluent Schema Registry is the open-source serving layer for schema metadata used in Apache Kafka data pipelines. It exposes a RESTful interface for storing and retrieving Avro, JSON Schema, and Protobuf schemas, manages schema evolution through configurable compatibility rules (BACKWARD, FORWARD, FULL, and transitive variants), supports schema references and contexts, and integrates with Kafka producers and consumers via shipped serializers and deserializers. Schema Registry is distributed under the Confluent Community License and is a core component of both Confluent Platform and Confluent Cloud.
