Viewing Kafka Data Production and Consumption Details

Scenario

On Kafka UI, you can view topic details, modify topic configurations, add topic partitions, delete topics, and view the number of data records produced in different time segments in real time.

• In security mode, Kafka UI does not authenticate the operation of viewing topic details. That is, any user can query topic information. To modify topic configurations, add topic partitions, or delete topics, ensure that the Kafka UI login user belongs to the kafkaadmin user group or grant the corresponding operation permissions to the user. Otherwise, the authentication fails.
• In non-security mode, Kafka UI does not authenticate any operation.
• This section applies only to MRS 3.1.2 or later.
