Video courses covering Apache Kafka basics, advanced concepts, setup and use cases, and everything in between. Support for these new serialization formats is not limited to Schema Registry, but provided throughout Confluent Platform. Additionally, Schema Registry is extensible to support adding custom schema formats as schema plugins. The serializers can automatically register schemas when serializing a Protobuf message or a JSON-serializable object. The Protobuf serializer can recursively register all imported schemas,. The serializers and deserializers are available in multiple languages, including Java,.

You are viewing documentation for an older version of Confluent Platform. For the latest, click here. Typically, IndexedRecord will be used for the value of the Kafka message. If used, the key of the Kafka message is often of one of the primitive types. When sending a message to a topic t , the Avro schema for the key and the value will be automatically registered in Schema Registry under the subject t-key and t-value , respectively, if the compatibility test passes. The only exception is that the null type is never registered in Schema Registry. In the following example, we send a message with key of type string and value of type Avro record to Kafka. A SerializationException may occur during the send call, if the data is not well formed. In the following example, we receive messages with key of type string and value of type Avro record from Kafka. When getting the message key or value, a SerializationException may occur if the data is not well formed. Determines how to construct the subject name under which the key schema is registered with the Schema Registry. Any implementation of io. SubjectNameStrategy can be specified.

Note The full class names for the above strategies consist of the strategy name prefixed by io.

The Confluent Schema Registry based Avro serializer, by design, does not include the message schema; but rather, includes the schema ID in addition to a magic byte followed by the normal binary encoding of the data itself. You can choose whether or not to embed a schema inline; allowing for cases where you may want to communicate the schema offline, with headers, or some other way. This is in contrast to other systems, such as Hadoop, that always include the schema with the message data. To learn more, see Wire format. Typically, IndexedRecord is used for the value of the Kafka message. If used, the key of the Kafka message is often one of the primitive types mentioned above.

Whichever method you choose for your application, the most important factor is to ensure that your application is coordinating with Schema Registry to manage schemas and guarantee data compatibility. There are two ways to interact with Kafka: using a native client for your language combined with serializers compatible with Schema Registry, or using the REST Proxy. Most commonly you will use the serializers if your application is developed in a language with supported serializers, whereas you would use the REST Proxy for applications written in other languages. Java applications can use the standard Kafka producers and consumers, but will substitute the default ByteArraySerializer with io. KafkaAvroSerializer and the equivalent deserializer , allowing Avro data to be passed into the producer directly and allowing the consumer to deserialize and return Avro data. For a Maven project, include dependencies within the dependencies tag for the Avro serializer and for your desired version of Kafka:. In your code, you can create Kafka producers and consumers just as you normally would, with two adjustments:.

Determines how to construct the subject name under which the key schema is registered with the Schema Registry. The serializers can automatically register schemas when serializing a Protobuf message or a JSON-serializable object. For Protobuf, the message name. Determines how to construct the subject name under which the value schema is registered with Schema Registry. Typically the referenced schemas would be registered first, then their subjects and versions can be used when registering the schema that references them. Tip You must provide the full path to the schema file even if it resides in the current directory.

What is the simplest way to write messages to and read messages from Kafka, using de serializers and Schema Registry? Next, create the following docker-compose. Your first step is to create a topic to produce to and consume from.

To ensure stability for clients, Confluent Platform and its serializers ensure the following:. InputStream ; import java. The command line producer and consumer are useful for understanding how the built-in Avro schema support works on Confluent Platform and Confluent Cloud. In future requests, you can use this schema ID instead of the full schema, reducing the overhead for each request. Changing a single value into a member of a new oneof is compatible.
