> Key: KAFKA-19558
> URL: https://issues.apache.org/jira/browse/KAFKA-19558
> Project: Kafka
> Issue Type: Bug
> Components: metrics, offset manager
> Affects Versions: 2.7.1
> Reporter: zhangtongr
> Assignee: Ranuga Disansa
> Priority: Blocker
>
> Description:
> When running the following command in a Kafka cluster with a large number of
> consumer groups (over 380) and topics (over 500), the
> kafka-consumer-groups.sh --describe --all-groups operation consistently times
> out and fails to return results.
> Command used:
> ./kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe
> --all-groups
> Observed behavior:
> The command fails with a TimeoutException, and no consumer group information
> is returned. The following stack trace is observed:
> java.util.concurrent.ExecutionException:
> org.apache.kafka.common.errors.TimeoutException:
> Call(callName=describeConsumerGroups, deadlineMs=1753170317381, tries=1,
> nextAllowedTryMs=1753170317482) timed out at 1753170317382 after 1 attempt(s)
> at
> org.apache.kafka.common.internals.KafkaFutureImpl.wrapAndThrow(KafkaFutureImpl.java:45)
> at
> org.apache.kafka.common.internals.KafkaFutureImpl.access$000(KafkaFutureImpl.java:32)
> ...
> Caused by: org.apache.kafka.common.errors.TimeoutException:
> Call(callName=describeConsumerGroups, deadlineMs=..., tries=1, ...) timed out
> Caused by: org.apache.kafka.common.errors.TimeoutException: Timed out waiting
> to send the call. Call: describeConsumerGroups
> Expected behavior:
> The command should be able to return the description of all consumer groups,
> or at least fail more gracefully. Ideally, there should be:
> A way to paginate or batch the describe operation;
> Or configuration options to increase internal timeout thresholds;
> Or better recommendations for dealing with large clusters.
> Additional context:
> Manually describing individual consumer groups via --group performs as
> expected and returns data quickly.
> The issue appears to scale linearly with the number of consumer groups.
