Setting Topic Traffic Throttling Rule

Last updated: 2022-06-22 15:01:35


    You can set a traffic throttling policy for a topic to prevent its excessive traffic from affecting other topics.


    1. Log in to the CKafka console.
    2. Click Instance List on the left sidebar and click the ID/Name of the target instance to enter the instance details page.
    3. On the instance details page, select Topic Management.
    4. In the Operation column, click Edit > Traffic Throttling and set the threshold.
      • Max Topic Production Traffic: This value excludes replica traffic and ranges from 1 MB/s to the maximum bandwidth purchased for the instance / number of replicas of the topic.
      • Max Topic Consumption Traffic: This value ranges from 1 MB/s to the maximum bandwidth purchased for the instance.

    • The underlying code throttles the broker traffic. The actual throttling threshold (which is an integral multiple of the broker count) may differ slightly from the threshold you set.
    • For more information on the soft traffic throttling mechanism, see Traffic Throttling.
