- Fees after the resource configuration change:
- Scale-out (Master Scale-Up or Slave Scale-Out): You must pay the relevant upgrade fees.
- Scale-in (Master Scale-Down or Slave Scale-In): The refund from the scale-in is returned to your account.
- After you perform Master Scale-Up or Slave Scale-Out, you must add required IP addresses to a whitelist of the database. For more information, see Configure a whitelist for accessing storage resources.
You can modify the configuration of Master Specifications or Slave Quantityto change the configuration of the cluster.
