             Summary: Potential delivery slow-down for record-limit share 
consumers when draining record backlog
                 Key: KAFKA-20460
                 URL: https://issues.apache.org/jira/browse/KAFKA-20460
             Project: Kafka
          Issue Type: Bug
          Components: clients, core
    Affects Versions: 4.2.0
            Reporter: Andrew Schofield
            Assignee: Andrew Schofield


When draining a backlog of records using share consumers with record-limit 
acquisition mode, it has been observed that sometimes there is a slow down in 
the consumption rate of records. This does not always occur, it does not occur 
for batch-optimized acquisition mode, and it does not occur when there is 
active production of records to the topic being consumed.

Thanks to [~vanlightly] for discovering this issue,
