A subscription cluster is automatically released after it expires. If you want to continue to use the cluster, you must renew the cluster before it is released to extend the validity period of the cluster. This topic describes how to manually renew clusters and enable or disable auto-renewal for clusters.

Prerequisites

The cluster that you want to renew is in a normal or frozen state.

Usage notes

A subscription cluster has a validity period. If you do not renew a subscription cluster before the end of the validity period, services may be interrupted or even data may be lost. Pay-as-you-go clusters never expire and do not require renewal.

Manually renew a cluster

  1. Log on to the Realtime Compute for Apache Flink console.
  2. On the Fully Managed Flink tab, find the cluster that you want to renew.
  3. In the Actions column, choose More > Renew.
  4. In the Renew dialog box, configure the Renewal Duration parameter.
    You can renew a cluster on a monthly basis.
  5. Read and select Terms of Service.
  6. Click OK.
    After you complete the payment, the cluster is automatically renewed.

Enable auto-renewal for clusters

If you enable auto-renewal for clusters, you do not need to manually renew the clusters on a regular basis. Auto-renewal also helps prevent service interruptions that occur if you do not renew clusters within the specified period. You can perform one of the following steps to enable auto-renewal for a cluster:
  • Enable auto-renewal on the buy page
    Log on to the Realtime Compute for Apache Flink console. In the Fully Managed Flink section, click Purchase. On the page that appears, select Enable for Auto-renewal, as shown in the following figure. For more information about how to create a fully managed Flink cluster, see Procedure for activating the service. Enable auto-renewal on the buy page
  • Enable auto-renewal on the Renewal page
    1. Log on to the Realtime Compute for Apache Flink console.
    2. In the top navigation bar, choose Expenses > Renewal Management.
    3. On the Renewal page of the Billing Management console, configure the Validity Period, Instances, and Region parameters to search for the clusters for which you want to enable auto-renewal.
    4. On the Manual tab, enable auto-renewal for one or more clusters.
      • Enable auto-renewal for one cluster: Find the cluster for which you want to enable auto-renewal and click Enable Auto Renewal in the Actions column.
      • Enable auto-renewal for multiple clusters: Select the clusters for which you want to enable auto-renewal and click Enable Auto Renewal below the cluster list.
    5. In the Enable Auto Renewal dialog box, configure the Unified Auto Renewal Cycle parameter and click Auto Renew.

      If the clusters appear in the list on the Auto tab, auto-renewal is enabled for the clusters.

Disable auto-renewal for clusters

If you enable auto-renewal for a cluster, the system automatically deducts fees from your account balance nine days before the cluster expires. If you no longer require auto-renewal for the cluster after the current billing cycle, you can disable auto-renewal for the cluster before the system deducts the fees for the next billing cycle.

  1. Log on to the Realtime Compute for Apache Flink console.
  2. In the top navigation bar, choose Expenses > Renewal Management.
  3. On the Renewal page of the Billing Management console, configure the Validity Period, Instances, and Region parameters to search for the clusters for which you want to disable auto-renewal.
  4. On the Auto tab, disable auto-renewal for one or more clusters.
    Method Operation Description
    Enable manual renewal
    • Enable manual renewal for one cluster: Find the cluster for which you want to enable manual renewal and click Enable Manual Renewal in the Actions column.
    • Enable manual renewal for multiple clusters: Select the clusters for which you want to enable manual renewal and click Enable Manual Renewal below the cluster list.
    After you enable manual renewal for a cluster, you must manually renew the cluster before it expires. For more information, see Manually renew a cluster.
    Enable non-renewal
    • Enable non-renewal for one cluster: Find the cluster for which you want to enable non-renewal and click Nonrenewal in the Actions column.
    • Enable non-renewal for multiple clusters: Select the clusters for which you want to enable non-renewal and click Set as Nonrenewal below the cluster list.
    After you enable non-renewal for a cluster, the cluster no longer provides services after it expires, and you are notified about the cluster expiration only once. If you want to continue to use the cluster, you can manually renew the cluster or modify the renewal settings of the cluster before it expires.
  5. Click OK.
    If the clusters appear in the list on the Manual or Nonrenewal tab, auto-renewal is disabled for the clusters.
