Alexander Koval created KAFKA-6396: -------------------------------------- Summary: Possibly kafka-connect converter should be able to stop processing chain Key: KAFKA-6396 URL: https://issues.apache.org/jira/browse/KAFKA-6396 Project: Kafka Issue Type: Wish Components: KafkaConnect Affects Versions: 1.0.0 Reporter: Alexander Koval Priority: Minor
At present only transformations can discard records returning null. But I think sometimes it would be nice to discard processing chain after converting message. For example I have some tags shipped with a message key and I want to stop processing the message after converting its key (there are a lot of messages and I don't want to deserialize message values that I don't need). At the moment to do that I should disable converters and move message deserializing to the transformation chain: {code} key.converter=org.apache.kafka.connect.converters.ByteArrayConverter value.converter=org.apache.kafka.connect.converters.ByteArrayConverter transforms=proto,catalog transforms.proto.type=company.evo.kafka.ProtobufTransformation transforms.proto.key.protobuf.class=company.evo.uaprom.indexator.KeyProto$KeyMessage transforms.proto.value.protobuf.class=company.evo.uaprom.indexator.catalog.CompanyProto$UniversalCompanyMessage transforms.proto.tag=catalog {code} If [WorkerSinkTask|https://github.com/apache/kafka/blob/1.0.0/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/WorkerSinkTask.java#L453] checked converted values on {{null}} it would solved my problem more gracefully -- This message was sent by Atlassian JIRA (v6.4.14#64029)
