Establishing Manual Scaling
Last updated: 2023-12-27 11:02:38
This section describes how to enable and disable manual scaling.
Prerequisites
The instance architecture uses MySQL general two-node/three-node or single-node local disk (read-only instance).
The instance specification is equal to or less than 32 cores before the CPU Elastic Scaling feature is enabled.
Your Tencent Cloud account has sufficient balance.
Note:
Enabling Manual Scaling
1. Log in to the TencentDB for MySQL console. In the instance list, click an instance ID or Manage in the operations column to go to the instance details page.
2. On Instance Details -> CPU Auto Scaling, click Enable.
3. In the CPU Auto Scaling window, complete the settings, confirm the scaling cost, and click Scale Now.
Parameter | Description |
CPU Auto Scaling Type | Select Manual Scaling. |
Additional CPU Cores Increase | Set the number of additional CPU cores to add manually. Scaling by 1 core is supported. The maximum number of additional CPU cores is equal to the CPU cores of the current specification. For example, the maximum number of additional CPU cores for the 8-core 16 GB specification is 8. |
Additional IOPS Increase | For each single core increase in CPU, IOPS is concurrently increased by 1,000. |
4. After manual scaling is enabled, the instance's CPU will immediately scale out according to the number of additional CPU cores. You can view the current instance's CPU on the Instance Detail -> CPU Elastic Scaling page.
Before Manual Scaling:
After Manual Scaling:
Note：
After manual scaling is enabled, if you need to modify the number of additional CPU cores, you can access Instance Detail -> CPU Elastic Scaling and click Edit for reconfiguration.
Disabling Manual Scaling
Note：
If manual scaling is not disabled, billing will continue.
After manual scaling is disabled, the expanded CPU will promptly restore to its original core count.
1. Log in to the TencentDB for MySQL console. In the instance list, click an instance ID or Manage in the operations column to go to the instance details page.
2. Navigate to Instance Details > CPU Elastically Scalable and click Disable.
3. In the pop-up window End CPU Scaling, click OK.
