Configuration Adjustment
Last updated: 2025-08-14 11:37:45
When the instance performance cannot meet business changes or is in excess, you can perform the configuration adjustment operation to meet business needs or save costs.
Configuration Adjustment Capabilities
Compute and storage are not separated for read-only analysis engine instances of TencentDB for MySQL. Therefore, cross-server configuration adjustment may be required in case of resource scale-out or disk capacity shrinkage. During instance configuration adjustment, an instance node with new specifications will be started automatically. After node data synchronization is completed, the access route will switch from the original node to the new node. At this time, the configuration adjustment operation is completed.
Directions
Note:
Read-only analysis engine instances currently adopt the method of pulling data from the read-write instance within the cluster by default to create nodes. Therefore, it is recommended that you perform configuration adjustment operations during off-peak hours.
1. Log in to the TencentDB for MySQL console.
2. Find the read-only analysis engine instance that requires configuration adjustment in the instance list, and choose More > Adjust Configurations in the Operation column.
3. Adjust the compute specifications and disk size of the instance as needed on the configuration adjustment page, select the operation time, and click Submit.
Note:
Note: You can check the notes on the actual configuration adjustment page for whether the configuration adjustment will trigger data migration and instance restart. Select the operation time for configuration adjustment according to actual business needs.
If you select Upon upgrade completion, switch will be triggered right after configuration adjustment is completed.
If you select Within maintenance window, switch will be performed during the maintenance period of the instance. To modify the instance maintenance period, see Setting Instance Maintenance Time.
