Matthias J. Sax updated KAFKA-4218: ----------------------------------- Summary: Enable access to key in ValueTransformer (was: Enable access to key in {{ValueTransformer}}) > Enable access to key in ValueTransformer > ---------------------------------------- > > Key: KAFKA-4218 > URL: https://issues.apache.org/jira/browse/KAFKA-4218 > Project: Kafka > Issue Type: Improvement > Components: streams > Affects Versions: 0.10.0.1 > Reporter: Elias Levy > Labels: api, needs-kip, newbie > > While transforming values via {{KStream.transformValues}} and > {{ValueTransformer}}, the key associated with the value may be needed, even > if it is not changed. For instance, it may be used to access stores. > As of now, the key is not available within these methods and interfaces, > leading to the use of {{KStream.transform}} and {{Transformer}}, and the > unnecessary creation of new {{KeyValue}} objects. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
