Chris Egerton commented on KAFKA-17493: --------------------------------------- Not sure! On a high level it looks like the consumer groups for sink tasks aren't able to commit the expected offsets in time. If I had to guess I'd say this is because the consumers aren't actually consuming that data, possibly because of an ongoing rebalance, but I haven't verified that. > Sink connector-related OffsetsApiIntegrationTest suite test cases failing > more frequently with new consumer/group coordinator > ----------------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-17493 > URL: https://issues.apache.org/jira/browse/KAFKA-17493 > Project: Kafka > Issue Type: Test > Components: connect, consumer, group-coordinator > Reporter: Chris Egerton > Priority: Major > > We recently updated trunk to use the new KIP-848 consumer/group coordinator > by default, which appears to have led to an uptick in flakiness for the > OffsetsApiIntegrationTest suite for Connect (specifically, the test cases > that use sink connectors, which makes sense since they're the type of > connector that uses a consumer group under the hood). > Gradle Enterprise shows that in the week before that update was made, the > test suite had a flakiness rate of about 4% > (https://ge.apache.org/scans/tests?search.rootProjectNames=kafka&search.startTimeMax=1724558400000&search.startTimeMin=1723953600000&search.tags=trunk&search.timeZoneId=America%2FNew_York&tests.container=org.apache.kafka.connect.integration.*&tests.sortField=FLAKY), > and in the week and a half since, the flakiness rate has jumped to 17% > (https://ge.apache.org/scans/tests?search.rootProjectNames=kafka&search.startTimeMax=1725681599999&search.startTimeMin=1724731200000&search.tags=trunk&search.timeZoneId=America%2FNew_York&tests.container=org.apache.kafka.connect.integration.*&tests.sortField=FLAKY). -- This message was sent by Atlassian Jira (v8.20.10#820010)
