Overview

Description

Yearly/Monthly Kafka instances cannot run after their subscription expires. To continue using them, renew your subscription within a specified period. Otherwise, your instance resources will be automatically released, and your data will be lost and cannot be restored.

Only yearly/monthly Kafka instances can be renewed. Pay-per-use Kafka instances can run as long as you have sufficient account balance.

If your subscription is renewed before it expires, all resources are retained and your Kafka instance is not affected. For details about the statuses of a Kafka instance after it expires, see Impact of Expiration.

Renewal Functions

Table 1 describes the functions related to the renewal of yearly/monthly Kafka instances.

Description

Manual renewal

To use a yearly/monthly Kafka instance longer, renew the subscription any time on the console as long as the instance is not automatically deleted.

Auto renewal

After auto-renewal is enabled, Kafka instances are automatically renewed before the subscription expires. This prevents resources from being automatically deleted in the event that you forget to manually renew the subscription.

You can renew your subscription across the life cycle of your yearly/monthly Kafka instance, as shown in Figure 1.

Figure 1 Life cycle of a Kafka instance
  • A Kafka instance is in the Running state from the time when it is purchased to the time when it expires.
  • After the instance expires, its status changes to Expired.
  • If the Kafka instance is not renewed upon expiration, the instance enters the grace period. If the instance is not renewed after the grace period expires, the status changes to Frozen.
  • If you do not renew your subscription after the grace period expires, your resource enters a retention period. If you do not renew the subscription within the retention period, your resource is automatically deleted.

Auto-renewal can be enabled any time before a Kafka instance expires. The system attempts to automatically renew the instance at 03:00 seven days (default, and can be customized) before the instance expires. If the fee deduction fails, there is one attempt at 03:00 every day until the instance expires or the renewal is successful.
