[jira] [Commented] (FLINK-8354) Flink Kafka connector ignores Kafka message headers

    [ https://issues.apache.org/jira/browse/FLINK-8354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16659449#comment-16659449 ] 

ASF GitHub Bot commented on FLINK-8354:
---------------------------------------

alexeyt820 commented on issue #6615: [FLINK-8354] [flink-connectors] Add ability to access and provider Kafka headers
URL: https://github.com/apache/flink/pull/6615#issuecomment-431860212
 
 
   Rebased on top of #6703 and implemented KeyedDeserializationSchema.Record for Kafka 2.0 (had to keep KeyedDeserializationSchema.Record because KeyedDeserializationSchema is used by legacy connectors as well.
   I will create PR for [FLINK-8500](https://issues.apache.org/jira/browse/FLINK-8500)(Timestamp)  on top of this PR.

> Kafka has introduced notion of Header for messages in version 0.11.0.0  https://issues.apache.org/jira/browse/KAFKA-4208.
> But flink-connector-kafka-0.11_2.11 which supports kafka 0.11.0.0 ignores headers when consuming kafka messages. 
> It would be useful in some scenarios, such as distributed log tracing, to support message headers to FlinkKafkaConsumer011 and FlinkKafkaProducer011.
