Matthias J. Sax commented on KAFKA-12213:
-----------------------------------------
It's totally fine to implement it incrementally across multiple releases.
IIRC, when KIP-149 was done, we did not have a Scala API yet. If there are
issues, we should discuss solutions on the dev mailing list as follow up, and
update the KIP accordingly.
> Kafka Streams aggregation Initializer to accept record key
> ----------------------------------------------------------

> Key: KAFKA-12213
> URL: https://issues.apache.org/jira/browse/KAFKA-12213
> Project: Kafka
> Issue Type: New Feature
> Components: streams
> Reporter: Piotr Fras

> Sometimes Kafka record key contains useful information for creating a zero
> object in aggregation Initializer. This feature is to add kafka record key to
> Initializer.
> There were two approaches I considered to implement this feature, one
> respecting backwards compatibility for internal and external APIs and the
> other one which is not. I chose the latter one as it was more strait-forward.
> We may want to validate this approach tho.
