Restarting a Kafka Instance

Notes and Constraints

• When a Kafka instance is being restarted, message consumption and production requests of clients will be rejected.
• To maintain service connections during instance restart, configure the retry mechanism on the client.

Prerequisite

The status of the Kafka instance you want to restart is either Running or Faulty.

Procedure

1. Log in to the Kafka console.
2. Click in the upper left corner to select the region where your instance is located.
3. Restart Kafka instances using one of the following methods:
   • Select one or more Kafka instances and click Restart in the upper left corner.
   • In the row containing the Kafka instance to be restarted, click More > Restart.
   • Click the desired Kafka instance to go to the instance details page. In the upper right corner, click > Restart.

4. In the Restart Instance dialog box, click Yes to restart the Kafka instance.

   It takes 3 to 15 minutes to restart a Kafka instance. After the instance is successfully restarted, its status should be Running.

   

   Restarting a Kafka instance only restarts the instance process and does not restart the VM where the instance is located.
