Subject [jira] [Commented] (KAFKA-671) DelayedProduce requests should not hold full producer request data
Date Tue, 15 Jan 2013 19:10:14 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13554172#comment-13554172

Neha Narkhede commented on KAFKA-671:
-------------------------------------

2. You maybe right. However, given that you set a large enough young gen compared to the total
heap size, I wonder what is the impact of nullifying the data. It will be worth doing a quick
experiment to study GC patterns and confirm that it does help. The only downside of this approach
is that it looks ugly.
