["Jordan Moore (JIRA)" <ji...@apache.org>]

Jordan Moore commented on NIFI-4487:
------------------------------------

I am interested in this ticket for a MirrorMaker-like alternative. 

For producer, would be nice to see the option to use either a timestamp that can come from attributes, or data itself. (But putting a processor ahead of the publish to extract data to add the attribute is okay).

For consumer, extract mentioned metadata and expose as attributes.

> Starting from kafka v10 kafka provides info about message timestamp.
> We should expose that data together with other attributes (like topic, partition, offset).
> We should add:
> @WritesAttribute(attribute = KafkaProcessorUtils.KAFKA_TIMESTAMP, description = "Kafka message timestamp"),
>         @WritesAttribute(attribute = KafkaProcessorUtils.KAFKA_TIMESTAMP_TYPE, description = "Kafka message timestamp type")
