[jira] [Commented] (KAFKA-736) Add an option to the 0.8 producer to mimic 0.7 producer behavior

    [ https://issues.apache.org/jira/browse/KAFKA-736?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13577800#comment-13577800 ]

Jun Rao commented on KAFKA-736:
-------------------------------

Because of the problem identified in KAFKA-706, only the v3 patch will work. The v3 patch needs to be rebased though. Also, not sure why it includes changes related to Hadoop bridge. Is this patch mixed with another one?

> I profiled a producer throughput benchmark between a producer and a remote broker. It turns out that the background send threads spends ~97% of its time waiting to read the acknowledgement from the broker.
> I propose we change the current behavior of request.required.acks=0 to mean no acknowledgement from the broker. This will mimic the 0.7 producer behavior and will enable tuning the producer for very high throughput.
