---------------------------------
Summary: Admin.listConsumerGroups should allow filtering,
pagination
Key: KAFKA-14335
URL: https://issues.apache.org/jira/browse/KAFKA-14335
Project: Kafka
Issue Type: Improvement
Components: admin, clients, protocol
Affects Versions: 3.3.0
Reporter: Kirk True
Assignee: Kirk True
The
[`Admin.listConsumerGroups`|https://kafka.apache.org/33/javadoc/org/apache/kafka/clients/admin/Admin.html#listConsumerGroups--]
is the interface for clients to view the consumer groups in the cluster. When
the list of consumer groups becomes very large, it can cause problems for the
client (e.g., OOM errors) as well as overhead for the broker and network.
The proposal is to enhance the
[`ListConsumerGroupsOptions`]([https://kafka.apache.org/33/javadoc/org/apache/kafka/clients/admin/ListConsumerGroupsOptions.html)]
class to have optional values such as:
* Consumer group ID regex (evaluated on broker)
* Pagination token (consumer group ID, probably)
This will require a KIP since it is enhancing the admin API, protocol, and
broker.
