Description

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.
