Message Queue for Kafka

Topic management

View topic details

After creating a Topic, you can view detailed information about the Topic on the console as you need. You can also view the details of its partitions, including topic details, partition information, and consumer connection details.

Prerequisites

A Message Queue for Kafka instance and a Topic are created. For detailed steps, refer to Create instance and Create topic.

View topic details

Select the region where the instance is located on the top menu bar.

Click the specified instance name on the Instances page.

Click Topic management on the tab bar.

Find the target Topic and view its basic information.

If the number of topics is large, we recommend that you search by topic name in the top right corner or filter by Topic tags. The topic list mainly displays topic name, status, number of partitions, number of replicas, message retention period, data volume, description, tags, and creation time.

Click the topic name to view detailed information for all partitions within the Topic.

For detailed explanations of each tab, refer to Topic details, Partition information, and Consumer connection information.

Data description

Topic details

The Topic details tab displays basic information, parameter configuration, and running status of the Topic. If you need to adjust the topic's parameter configuration, click Modify in the Parameter configuration section.

tip

The actual effective configurations in the instance, such as Message retention period, are based on the parameter settings of each Topic. The parameter configuration at the instance level determines the default parameter values for each instance. After modifying the instance parameter configuration, the default parameter values for newly created Topics are determined by the instance's parameter configuration.

Region	Display items	Description
Basic information	Topic name	The name of the topic.
		Description	Brief description of the Topic
		Creation time	Topic creation time.
Parameter configuration	Number of partitions	Number of partitions in the Topic.
		Number of replicas	Number of replicas for the topic partition. Displays data backup on the corresponding number of replicas.
		Minimum number of in-sync replicas	Minimum number of synchronous replicas for the topic. The larger this value, the better the data reliability. However, the availability will decrease.
		Message retention period	Maximum retention period for messages in this topic, i.e., message storage time. Consumers must consume messages before this time expires. Otherwise, the messages will be deleted and can not be consumed.
		Maximum message size	The maximum message size in this topic.
		Message cleanup policy	Cleanup policy for messages in this topic.
Running status	Data volume	Total storage space used by this topic instance and its percentage.

Partition information

The partition information tab displays detailed information for all partitions of this topic. You can also search partitions by partition number in this tab.

Display items	Description
Partition number	Partition number.
Leader	The leader handles all read and write requests for the partition. Follower passively and regularly replicates data from the leader.
Replica	Replica list
ISR	Copies of synchronized messages.
Unsynchronized replicas	Number of unsynchronized copies. Supports filtering partitions with unsynchronized copies.
Start offset	Start offset of message writing.
End offset	The last position where the message is written.
Number of stored messages	The number of messages stored in this partition.

Consumer connection information

The consumer connection information tab displays all group connection information for the current topic. You can also filter groups by group ID.

Display items	Description
Group ID	Group ID that consumes this topic.
Status	Status of the group For each status description, refer to Group status description.
Protocol type	The consumption protocol type that is specified by consumer group If you choose the standard Kafka consumption protocol, it will display as consumer. If you choose other protocol types, it will display the corresponding protocol name. For example, the type shows as connect when accessing via Kafka-Connector. If you use consumption method that can customize partition, this field is empty.
Balancing algorithm	The algorithm used to assign partitions to consumers. It is specified by the consumer client. If you use consumption method that can customize partition, this field is empty.
