             Summary: Add an option to the 0.8 producer to mimic 0.7 producer behavior
                 Key: KAFKA-736
                 URL: https://issues.apache.org/jira/browse/KAFKA-736
             Project: Kafka
          Issue Type: Improvement
          Components: producer 
    Affects Versions: 0.8
            Reporter: Neha Narkhede
            Assignee: Neha Narkhede
            Priority: Blocker


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.
