What is Schema Registry?
Schema Registry is a central repository for storing and managing schemas for data in Kafka topics. Schemas are used to define the structure of data, and they can be used to ensure data consistency and compatibility as schemas evolve.
Several popular implementations of Schema Registry are commonly used with Apache Kafka. Some of them include:
Confluent Schema Registry: It is the official Schema Registry implementation provided by Confluent. It offers advanced features and tight integration with the Confluent Platform.
Apicurio Registry: It is an open-source Schema Registry that provides schema management capabilities for Kafka and other messaging and event streaming platforms.
These implementations support Avro, JSON Schema, and Protobuf schemas and offer features like schema validation, versioning, compatibility checks, and schema evolution.
