-------------------------------
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.
