What Cloudera Schema Registry is
Cloudera Schema Registry centrally stores schemas for streaming data, giving applications a shared place to validate event data and manage changes to message formats. It supports Avro and JSON schemas, including Avro logical types. Schema identifiers and versioning help track revisions, while searchable metadata and configurable backward, forward, full, or no compatibility checks support schema discovery and evolution. Its REST API handles schema and version management, imports and exports, search, aggregation, and Confluent-compatible endpoints. Documented integrations include custom NiFi processors and Kafka serializers and deserializers. Schema metadata can use MySQL, PostgreSQL, or Oracle; serializer and deserializer JARs can be stored on local filesystems or HDFS, with local storage as the default. The Kubernetes Operator edition packages Cloudera Runtime Schema Registry as a Helm chart. TLS can protect application, client, OAuth, and database traffic. In the documented secure Kubernetes setup, authentication and authorization use OAuth with an external server. The UI is limited to unauthenticated previews or development use; production installations requiring security should use the REST API. Pricing is on request, and the documented Kubernetes installation requires a valid Cloudera license and repository credentials.
