Manually Deleting Nodes from a GeminiDB DynamoDB-Compatible Instance

Scenarios

When workloads decrease, unnecessary compute resources will lead to wasted capacity and higher costs. You can release resources by deleting nodes from your GeminiDB DynamoDB-Compatible instance to adapt to workload changes and reduce costs.

Usage Notes

  • Deleted nodes cannot be recovered. Exercise caution when performing this operation.
  • Only pay-per-use instances can be deleted.
  • Deleting nodes will cause the OPS to decrease for a short period of time. Deleting nodes during off-peak hours.
  • If you enable operation protection to improve the security of your account and cloud products, two-factor authentication is required for sensitive operations. For details about how to enable operation protection, see Identity and Access Management User Guide.

Impact on Price

Yearly/Monthly

Deleting nodes

After nodes are deleted, the new configuration takes effect for the remaining subscription period. As the new configuration costs less than the previous one, Huawei Cloud will refund you the price difference.

Example (The specifications and prices below are for reference only. The actual prices are displayed on the console.)

Assume that you purchased a 6-node yearly/monthly GeminiDB DynamoDB-Compatible instance with 2 vCPUs and 12 GB of memory for one month on April 8, 2023 and reduced it to a 3-node instance with the same specifications on April 18, 2023. The price for the old configuration is $1,883.40 USD/month, and that for the new configuration is $941.70 USD/month. The price difference is calculated as follows:

Price difference = Price for the original instance configuration × Remaining period – Price for the new instance configuration × Remaining period

The remaining period in the formula is calculated by dividing remaining days in each calendar month by the total days in that month. In this example, the remaining period is 0.6581 [12 (remaining days in April)/30 (total days in April) + 8 (remaining days in May)/31 (total days in May)]. The refund amount is therefore $619.73 USD (1883.4 × 0.6581 – 941.7 × 0.6581).

For details, see Yearly/Monthly Billing.
