Alieh Saeedi updated KAFKA-20179:
---------------------------------
Summary: Avoiding headers deserialization while changelogging (was:
Changelog optimization)
> Avoiding headers deserialization while changelogging
> ----------------------------------------------------
>
> Key: KAFKA-20179
> URL: https://issues.apache.org/jira/browse/KAFKA-20179
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Alieh Saeedi
> Priority: Major
>
> When writing to the changelog topic, we currently need to deserialize the
> headers, which is not ideal. We should find a way to avoid this for
> efficiency reasons.
> Suggested solution by [~mjsax]: `We would couple ourselves strictly to the
> serialization format of headers inside the message format thought. While we
> already use the same format atm we are not tightly coupled atm. So we should
> consider the implications if we want to do go down this route. For the case
> that this part of the Kafka message format changes, it would impact KS, and
> this raised compatibility questions.`
