Yeva Byzek updated KAFKA-10595:
-------------------------------
Description:
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}
A contributing factor to the confusion around this scenario 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}}
