Changing a Yearly/Monthly Instance to Pay-per-Use

You can change a yearly/monthly GeminiDB DynamoDB-Compatible instance to pay-per-use to reclaim a portion of your subscription costs while adapting to your usage needs.

You can change the billing mode from yearly/monthly to pay-per-use in either of the following ways:

  • Immediate change: The remaining fee for the current billing cycle is refunded. Once the refund is processed, the billing mode is immediately changed to pay-per-use and auto-renewal is disabled.
  • Upon expiration: When the yearly/monthly subscription ends, the billing mode is automatically changed to pay-per-use and auto-renewal is disabled.

Constraints

Resources such as EIPs that are used by an instance may not support the change with this instance. For details about their billing mode change rules and handling methods, see Table 1.
