Chris McCarthy updated CAMEL-14935: ----------------------------------- Summary: KafkaConsumer commits old offset values in a failure scenario causing message replays and offset reset error (was: KafkaConsumer commits old offset values in certain failure case causing message replays and offset reset error) > KafkaConsumer commits old offset values in a failure scenario causing message > replays and offset reset error > ------------------------------------------------------------------------------------------------------------ > > Key: CAMEL-14935 > URL: https://issues.apache.org/jira/browse/CAMEL-14935 > Project: Camel > Issue Type: Bug > Components: camel-kafka > Affects Versions: 2.24.0 > Reporter: Chris McCarthy > Priority: Major > > We are getting unexpected offset reset errors occasionally. > The cause seems to be a failed commit on rebalance, leaving an old value in > the hashMap that is then re-read and re-committed across rebalances in > certain situations. > Our relevant configuration details are: > autoCommitEnable=false > allowManualCommit=true > autoOffsetReset=earliest > It seems when the KafkaConsumer experiences an Exception committing the > offset upon a rebalance, this leaves the old offset value in the > lastProcessedOffset hashMap. > A subsequent rebalance that assigns the same partition to the same consumer, > that then thereafter experiences another rebalance (before any messages have > been processed successfully as this will over write the invalid value and > self correct the problem) will commit this old offset again. This offset may > be very old if there have been many rebalances in between the original > rebalance that failed to commit its offset. > If the old offset is beyond the retention period and the message is no longer > available the outcome is an offset reset error. If the offset is within the > retention period all messages are replayed from that offset without an error > being thrown. -- This message was sent by Atlassian Jira (v8.3.4#803005)
