---------------------------------
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 .
