--------------------------------------

             Summary: Improve the documentation explaining why 
max.in.flight.requests.per.connection should not exceed 5.
                 Key: KAFKA-17926
                 URL: https://issues.apache.org/jira/browse/KAFKA-17926
             Project: Kafka
          Issue Type: Improvement
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai


We should highlight that the server [0] retains record metadata for the 5 most 
recent batches, so sending too many requests to a node simultaneously can break 
idempotence.
