Jun Rao commented on KAFKA-353:
-------------------------------
We need to support different levels of acks required by the producer. By
default (ack=-1), the response to the producer request is only sent when every
replica in ISR has received the message. If a producer specifies an ack >=0 (0
will be treated the same as 1), the response is sent after ack replicas have
received the message. The caveat is that if the specified ack is less than ISR,
the produced message could be lost if some broker fails.
> tie producer-side ack with high watermark and progress of replicas
