public class JsonSchemaKafkaSerializer<T>
extends AbstractKafkaSerializer<JsonSchema,T>
implements org.apache.kafka.common.serialization.Serializer<T>

An implementation of the Kafka Serializer for JSON Schema use-cases. This serializer assumes that the user's application needs to serialize a Java Bean to JSON data using Jackson. In addition to standard serialization of the bean, this implementation can also optionally validate it against a JSON schema.
