Obtaining All Databases in an Instance

This API is used to obtain the database list for a GeminiDB Redis instance.

Only the GeminiDB Redis API is supported.
This operation cannot be performed when the instance is in any of the following states: creating, changing specifications, changing database port, frozen, or abnormal.
Only databases of instances that contain data are returned.

Each account has permissions to call all APIs, but IAM users must have the required permissions specifically assigned.

If you are using role/policy-based authorization, see the required permissions in Permissions and Supported Actions.

If you are using identity policy-based authorization, the following identity policy-based permissions are required.
