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. > KIP-149: > https://cwiki.apache.org/confluence/display/KAFKA/KIP-149%3A+Enabling+key+access+in+ValueTransformer%2C+ValueMapper%2C+and+ValueJoiner -- This message was sent by Atlassian JIRA (v7.6.3#76005)
