What is the risk of increasing max.in.flight.requests.per.connection while also enabling retries in a producer?

Show Suggested Answer Hide Answer
Suggested Answer: B

Some messages may require multiple retries. If there are more than 1 requests in flight, it may result in messages received out of order. Note an exception to this rule is if you enable the producer settingenable.idempotence=true which takes care of the out of ordering case on its own. Seehttps://issues.apache.org/jira/browse/KAFKA-5494

But increasing max.in.flight.requests.per.connection can also improve throughput, so it's a trade-off.

I agree with Jame. Enabling retries in a producer can lead to duplicate messages being sent.

I think the risk is that at least once delivery is not guaranteed.
