             Summary: add request.required.acks=-2 to require acks from all replicas
                 Key: KAFKA-1537
                 URL: https://issues.apache.org/jira/browse/KAFKA-1537
             Project: Kafka
          Issue Type: Improvement
          Components: core
    Affects Versions: 0.8.1.1
            Reporter: Jiang Wu
            Priority: Minor


The current options for the producer parameter request.required.acks include 0, positive numbers and -1. -1 means the acks from replicas in ISR.

In a stress test, it's found that, if request.required.acks=-1 and the leader is receiving at high speed, then the followers will fail out of ISR. In this case, request.required.acks=-1 is equivelant to request.required.acks=1 because only the leader is in ISR.

It would be desirable to add request.required.acks=-2 to require acks from all replicas.
