Using the Schema Registry. Now that the Schema Registry is up and running, you can now use it in your applications to store data schemas for your Kafka topics. Start Kafka and Schema Registry confluent local start schema-registry. The Confluent CLI provides local mode for managing your local Confluent Platform installation.

To run an instance of Schema Registry against a local Kafka cluster (using the default configuration included with Kafka): mvn exec:java -pl :kafka-schema-registry -Dexec.args= " config/schema-registry.properties " This configuration requires a bit of an explanation. First, mp.messaging.connector.smallrye-kafka.apicurio.registry.url configure the schema registry URL. If you use the Confluent serde, instead of the Apicurio one, the property is named mp.messaging.connector.smallrye-kafka.schema.registry.url. The schema-registry-server-start script (and the schema-registry-run-class script it depends on) do things like handle -daemon mode, set Java memory options, setup default log configuration, and more, but ultimately the key piece is that they execute Java with io.confluent.kafka.schemaregistry.rest.SchemaRegistryMain as the main The important aspect for Schema registry is supporting schema evolution where schema can change over time. Each event will have an embedded schema ID in Wire format which will allow to deserialize the events on the consumer side. But in case, if you want to have strict schema validation before writing to Kafka topic, there are two options- The Java client's Apache Kafka client serializer for the Azure Schema Registry can be used in any Apache Kafka scenario and with any Apache Kafka® based deployment or cloud service. The following image shows the information flow of the schema registry with Event Hubs: The Confluence schema registry has seven compatibility types: BACKWARD, BACKWARD_TRANSITIVE, FORWARD, FORWARD_TRANSITIVE, FULL, FULL_TRANSITIVE, NONE.

So, basically, in the environment of the schema-registry the OP has to remove SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL and add SCHEMA_REGISTRY_KAFKASTORE_BOOTSTRAP_SERVERS: "PLAINTEXT://kafka:29092" Reference: kafkastore.connection.url is deprecated. – SergiyKolesnikov Jul 7 '20 at 18:08

It uses JSON for Create the Avro Schema. Before you Moreover, by using the following operations, the Schema Registry in Kafka allows us to manage schemas: Store schemas for keys and values of Kafka records List schemas by subject List all versions of a subject (schema) Retrieves a schema by version Retrieves a schema … The Schema Registry actually doesn’t know anything about our Kafka topics (we have not even created the persons-avro topic yet), and it is a convention (used by the serializers) to register schemas under a name that follows the -(key|value) format. Schema Registry is a distributed storage layer for schemas which uses Kafka as its underlying storage mechanism. Some key design decisions: Assigns globally unique ID to each registered schema. 2017-12-13 In order to work in high-security Kafka environments, we need to configure the schema registry so it can communicate with Kafka using the authenticated SASL mechanism.
