             Summary: Producer will enable EOS by default
                 Key: KAFKA-10619
                 URL: https://issues.apache.org/jira/browse/KAFKA-10619
             Project: Kafka
          Issue Type: Improvement
            Reporter: Cheng Tan
            Assignee: Cheng Tan


This is an after-work for KIP-185. 

In the producer config,
 # the default value of `acks` will change to `all`
 # `enable.idempotence` will change to `true`

[An analysis of the impact of max.in.flight.requests.per.connection and acks on 
Producer 
performance|https://cwiki.apache.org/confluence/display/KAFKA/An+analysis+of+the+impact+of+max.in.flight.requests.per.connection+and+acks+on+Producer+performance]
 indicates that changing `acks` from `1` to `all` won't increase the latency 
and decrease the throughput in a significant way.
