    ApsaraDB for ClickHouse:Modify the scaling settings of an ApsaraDB for ClickHouse Enterprise Edition cluster

    Last Updated:Jun 07, 2024

    ApsaraDB for ClickHouse Enterprise Edition clusters support scaling settings. This topic describes how to modify the scaling settings of an ApsaraDB for ClickHouse Enterprise Edition cluster.

    Background information

    The computing resources of an ApsaraDB for ClickHouse Enterprise Edition cluster are automatically scaled based on the cluster loads. The scaling settings allow you to configure a scaling range for the computing resources. The automatic scaling of computing resources is implemented by increasing or reducing the number of compute capacity units (CCUs). The scaling range is determined by the configured minimum number of CCUs and maximum number of CCUs. The number of CCUs is automatically increased or decreased based on business loads.

    Prerequisites

    An ApsaraDB for ClickHouse Enterprise Edition cluster is created. For more information, see Create an ApsaraDB for ClickHouse cluster.

    Usage notes

    • The computing resources after scale-down cannot be smaller than the configured minimum number of CCUs, and the computing resources after scale-up cannot be greater than the configured maximum number of CCUs.

    • The scaling of computing resources for an ApsaraDB for ClickHouse Enterprise Edition cluster takes effect immediately. Your business is not affected.

    • You are not charged for modifying the scaling range for the computing resources. The computing fees are determined by the usage of CCUs.

    Procedure

    1. Log on to the ApsaraDB for ClickHouse console.

    2. In the top navigation bar, select the region where the cluster that you want to manage is deployed.

    3. On the Clusters page, click the Enterprise Edition Clusters tab and click the ID of the cluster that you want to manage.

    4. In the Configuration Information section of the Cluster Information page, click Modify Scaling Configurations.

    5. In the Modify Scaling Configurations dialog box, set Maximum CCUs and Minimum CCUs based on your business requirements.

    6. Click OK.

      Important

      The state of the cluster changes to Changing. If the state changes from Changing to Running, the modification of the scaling settings is complete.
