Beam JIRA Bot updated BEAM-7047:
--------------------------------
Labels: stale-P2 (was: )
> Direct Runner loses checkpoint marks when committing offsets to Apache Kafka
> partitions using KafkaIO
> -----------------------------------------------------------------------------------------------------
>
> Key: BEAM-7047
> URL: https://issues.apache.org/jira/browse/BEAM-7047
> Project: Beam
> Issue Type: Bug
> Components: io-java-kafka, runner-direct
> Affects Versions: 2.9.0
> Reporter: Mark Norkin
> Priority: P2
> Labels: stale-P2
> Attachments:
> beam-direct-runner-not-finalize-all-kafka-offsets-master.zip

>
> On our project we are using Apache Kafka as a source for most of our Apache
> Beam pipelines.
> We would like to leverage manual offset commit functionality implemented by
> KafkaIO, and enabled by _commitOffsetsInFinalize_ option.
> We also written several tests that sort of represent and document this
> functionality, and should run during our CI process using Direct Runner.
> However we experienced issues during tests implementation, particularly we
> see that on Direct Runner not all checkpoint marks which in case of KafkaIO
> represent partition offsets are committed.
> I've created sample project, attached as external link and as src attachment
> to JIRA ticket, to showcase the issue.
> The result of this test execution is *_not_* deterministic, when failing the
> exemplary stacktrace is as follows:
> {code:java}
> org.awaitility.core.ConditionTimeoutException: Condition with alias 'sent raw
> messages are read and offsets are committed' didn't complete within 3 minutes
> because lambda expression in
> com.marknorkin.beam.directrunner.sample.ParserEndToEndFlowCommitOffsetsTest:
> expected <{raw_topic-0=10, raw_topic-1=10, raw_topic-2=10}> but was
> <{raw_topic-1=10, raw_topic-0=10}>.

> This issue is probably not specific to KafkaIO, as it Direct Runner when
> finalizing Checkpoint Marks works within general CheckpointMark interface.
