What To Do When the Database Capacity Reaches the Upper Limit?
To ensure reasonable use of resources, CloudBase imposes a database storage capacity limit for each environment. The database storage capacity of each environment is calculated separately.
If the remaining storage capacity of the database is below 10%, you will be notified via Short Message Service (SMS), Message Center, and mail. You can upgrade your environment version to enjoy more database storage capacity and avoid affecting the normal operation of your business.
If the database storage capacity of the environment is exhausted, writing data to the database is not allowed, but you can read and delete data.

Why Can Some Data In the Database Be Seen In the Console but Not Retrieved By the Client?
Please check the collection permissions. For permission types other than "public read," the system will enforce a check on the _openid field to see if it matches the current user identity.
If the data is added in the console, it is considered admin-added data and does not contain _openid information, so it does not belong to any user. This data can only be edited by the admin through the console and cannot be written through the client (even the admin cannot write through the client).
Can the Database Be Operated Directly Through the HTTP API?
It is not supported.
