    ApsaraDB for SelectDB:Start or suspend a cluster

    Last Updated:Mar 28, 2026

    Suspending a cluster releases its computing resources and stops billing for those resources, which reduces costs during idle periods. When you need the cluster again, start it to restore computing resources and resume normal operation.

    Prerequisites

    Before you begin, make sure that you have:

    • A SelectDB instance

    • A cluster in the instance that uses the pay-as-you-go billing method

    What happens when you suspend or start a cluster

    When you suspend a cluster:

    • Computing resources are released and billing for computing resources stops.

    • Cached data is retained, but billing for cached data and cache storage continues.

    • Billing for persistently stored data and storage resources of the instance is not affected.

    • All cluster operations are blocked — you cannot change cluster configurations, restart the cluster, or send read/write requests to the cluster.

    When you start a cluster:

    • Computing resources are provisioned and billing for computing resources resumes.

    • The cluster accepts read and write requests.

    Suspend a cluster

    1. Log on to the SelectDB console.

    2. In the top navigation bar, select the region where your instance resides.

    3. In the left-side navigation pane, click Instances. On the Instances page, find the instance and click the instance ID to go to the Instance Details page.

    4. In the left-side pane, click Cluster Management.

    5. On the Cluster Management page, find the cluster and click Pause in the Actions column.

    6. In the confirmation dialog, click OK.

      Note

      The suspend operation takes about 1 minute. The cluster status changes from Suspending to Suspended when the operation is complete.

    Start a cluster

    2. In the top navigation bar, select the region where your instance resides.

    3. In the left-side navigation pane, click Instances. On the Instances page, find the instance and click the instance ID to go to the Instance Details page.

    4. In the left-side pane, click Cluster Management.

    6. In the confirmation dialog, click OK.

      Note

      The start operation takes 1 to 10 minutes. The cluster status changes from Starting to Running when the operation is complete.
