             Summary: Explain idempotent producer in max.in.flight.requests.per.connection
                 Key: KAFKA-10595
                 URL: https://issues.apache.org/jira/browse/KAFKA-10595
             Project: Kafka
          Issue Type: Improvement
          Components: docs
            Reporter: Yeva Byzek


A user asked:

 
{quote}Is the idempotent producer also a total order producer? meaning, despite having max.inflight > 1, it will keep message production ordering? My understanding of this has always been no, but I'd like to confirm...
{quote}
 

I believe a contributing factor to this question is that [https://kafka.apache.org/documentation/#max.in.flight.requests.per.connection] reads

 
{quote}Note that if this setting is set to be greater than 1 and there are failed sends, there is a risk of message re-ordering due to retries (i.e., if retries are enabled).
{quote}
 

Suggestion: it may be clearer if we augmented this description to say that message re-ordering would not happen if {{enable.idempotent=true}}
