Create and manage config groups

Available in VPC

Config group is a feature that manages the Kafka configuration file applied to clusters. This guide describes how to create Kafka configuration files to apply to clusters, delete them, or change Kafka config settings.

Config group page

The page layout of Config group is as follows.

Create config group

You can create config groups. There is no need to specify additional settings since default values are automatically specified upon creating a config group.

The following describes how to create a config group.

1. From the NAVER Cloud Platform console, click the Services > Big Data & Analytics > Cloud Data Streaming Service > Config Group menus, in that order.
2. Click the [Create config group] button.
3. When the Create config group window appears, enter the required information.
   
   • Version: Select the Kafka version of the config group you want to create.
   • Config group name: Enter the name of the config group.
     • Only English lowercase letters, numbers, and hyphens (-) are allowed. Hyphens (-) can't be entered as the first or last character.
     • You can enter between 3 and 30 characters.
   • Description: Enter a brief description of the config group.
4. Click the [OK] button.
5. Check if the config group has been created.

Edit config group

The user doesn't have to specify additional config values since default values are applied to the config when creating a cluster. However, if they need to change the Kafka config settings, the user can directly change them using the Edit config group feature. Since the cluster may not operate normally in the process of the user arbitrarily changing the Kafka config settings, you should only change the config group if you have basic knowledge of Kafka.

The following describes how to edit a config group.

1. From the NAVER Cloud Platform console, click the Services > Big Data & Analytics > Cloud Data Streaming Service > Config Group menus, in that order.
2. Mark the checkbox of the config group you want to edit, and then click the [Edit config] button.
   • The configuration items that can be changed in Kafka's configuration file (Serverproperties) appear.
3. Change the Kafka config settings.
   • For descriptions on configurations, refer to Apache Kafka Documentation.
4. To reset the config with default values, click the [Reset to default] button.
5. Once the config edit is completed, click the [OK] button.
   

Apply config group to cluster

The following describes how to apply the config group to a cluster.

1. From the NAVER Cloud Platform console, click the Services > Big Data & Analytics > Cloud Data Streaming Service > Cluster menus, in that order.
2. In the details area of the cluster to apply the config group to, click the icon of the ConfigGroup.
   
3. When the Change config group window appears, select the config group you want to apply it to, and then click the [OK] button.
   
4. When the confirmation window for the config group change appears, click the [OK] button.
   • The changed content in the config group is applied to the cluster, and then the cluster is restarted.

Delete config group

You can delete config groups that are no longer in use. However, the config group can't be deleted if there is a cluster using it. You need to delete the cluster using the config group, or change the config group of that cluster.

The following describes how to delete a config group.

1. From the NAVER Cloud Platform console, click the Services > Big Data & Analytics > Cloud Data Streaming Service > Config Group menus, in that order.
2. Mark the checkbox of the config group to delete, and then click the [Delete] button.
3. When the Delete window appears, click the [OK] button.
