[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=13568192#comment-13568192 ]

---------------------------------

I tried the v2 patch linked above this morning against v0.8 HEAD.  It appears (after full throttle testing for over an hour) to have eliminated the problem originally reported in KAFKA-706.

> 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.
