Schema Registry catalog

The Schema Registry catalog allows you to access Kafka topics with registered schemas as Flink SQL tables.

Each Kafka topic will be mapped to a table with TableSchema that matches the Avro schema.

Maven Dependency
The following example shows how to register and use the Schema Registry catalog from Java:
SchemaRegistryClient client = new SchemaRegistryClient(

Map<String, String> connectorProps = new Kafka()

   "registry", new ClouderaRegistryCatalog("registry", client, connectorProps)
To use the Schema Registry catalog from the SQL client, you have to add it in the YAML configuration file to the catalogs section:
  - name: registry
    type: cloudera-registry
    # Registry Client standard properties <registry_url>:<port>/api/v1 …
    # Registry Client SSL properties
    registry.client.ssl.keyStorePath: ... 
    registry.client.ssl.sslProp: ... 
    # Kafka Connector properties <kafka_brokers>
    connector.startup-mode: earliest-offset
