--------------------------------------
Summary: StreamsGroupCommand does not display committed offsets
for repartition topics
Key: KAFKA-20306
URL: https://issues.apache.org/jira/browse/KAFKA-20306
Project: Kafka
Issue Type: Task
Components: streams
Reporter: Lucas Brutschy
Assignee: Alieh Saeedi
The kafka-streams-groups.sh tool does not display committed offsets for
repartition topics when using the --describe --verbose option. Repartition
topic offsets show as '-' instead of actual values. The root cause is in
StreamsGroupCommand.getCommittedOffsets(), which filters committed offsets to
only include topics from subtopology.sourceTopics(). Repartition topics are not
source topics — they are in repartitionSourceTopics(). This causes their
committed offsets to be dropped from the output. Meanwhile,
getTopicPartitions() correctly includes both sourceTopics() and
repartitionSourceTopics() when determining which topic-partitions to display,
so repartition topics appear in the output but without their offset data. The
fix is to also include repartitionSourceTopics() in the filter in
getCommittedOffsets(), consistent with what getTopicPartitions() already does.
