Thank you for your support of Alibaba Cloud. To continuously improve the user experience of SelectDB, we are rolling out the configuration modification feature for FE nodes. This allows you to customize the specifications and the number of FE nodes. Additionally, commercial billing will apply to large-scale FE resources exceeding 4 cores.

We recommend calculating the FeSize based on the current specifications and quantity of your FE nodes. If there are redundant FE nodes, you can adjust them to reasonable specifications and quantities that meet your business needs in order to control costs. Please also ensure that a valid payment method is linked to your account and that you have sufficient balance to avoid any service interruptions caused by overdue payments.
