------------------------------------
Summary: Changelog optimization
Key: KAFKA-20179
URL: https://issues.apache.org/jira/browse/KAFKA-20179
Project: Kafka
Issue Type: Sub-task
Reporter: Alieh Saeedi
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.`
