Guozhang Wang commented on KAFKA-12213: --------------------------------------- [~mjsax] Maybe we can break KIP-149/159 into smaller ones if [~MonCalamari] is only interested in this particular one? Or, if we feel that 149/159 could have a consensus soon and then we can just implement part of it (this ticket) as the first step, that would also be great. > 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 > Assignee: Piotr Fras > Priority: Minor > Labels: needs-kip > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
