             Summary: Consumer with isolation level as 'read_committed' are getting stuck for few partitions
                 Key: KAFKA-8109
                 URL: https://issues.apache.org/jira/browse/KAFKA-8109
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Love Singh


Hello , 

 

Consumers with isolation level set as 'read_committed' are getting stuck for few partitions in a topic , for other it is working fine .

Upon examination we have found out that the LSO(last stable offset) lag for those topic-partitions are more than 25K (JMX Metric : LastStableOffsetLag).

We can read for any offsets from these topic-partitions in read_commited before LSO but consumers gets stuck when it reaches LSO . READ_UNCOMMITED mode works fine .

We have seen below error repeatedly in our log for that partition :

_"Found no record of producerId on the broker. It is possible that the last message with the producerId has been removed due to hitting the retention limit."_

All the producers are transactional 

We are not sure what else to check here . Can some one please have a look .

 

Thanks .
