[jira] [Commented] (KAFKA-16684) FetchResponse#responseData could return incorrect data

    [ https://issues.apache.org/jira/browse/KAFKA-16684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17844251#comment-17844251 ] 

Chia-Ping Tsai commented on KAFKA-16684:
----------------------------------------

After [https://github.com/apache/kafka/commit/2b8aff58b575c199ee8372e5689420c9d77357a5] , I don't think the "cache" is useful. Hence, we can just remove the cache to fix this potential bug

> [https://github.com/apache/kafka/commit/2b8aff58b575c199ee8372e5689420c9d77357a5] make it accept input to return "partial" data. The content of output is based on the input but we cache the output ... It will return same output even though we pass different input. That is a potential bug.
