Package io.confluent.kafka.serializers.subject

Class TopicRecordNameStrategy

java.lang.Object

io.confluent.kafka.serializers.subject.RecordNameStrategy

io.confluent.kafka.serializers.subject.TopicRecordNameStrategy

All Implemented Interfaces:

SubjectNameStrategy, org.apache.kafka.common.Configurable

public class TopicRecordNameStrategy
extends RecordNameStrategy

For any record type that is published to Kafka topic <topic>, registers the schema in the registry under the subject name <topic>-<recordName>, where <recordName> is the fully-qualified record name. This strategy allows a topic to contain a mixture of different record types, since no intra-topic compatibility checking is performed. Moreover, different topics may contain mutually incompatible versions of the same record name, since the compatibility check is scoped to a particular record name within a particular topic.
