Obtaining Storage Information of a Bucket

Functions

This operation queries the number of bucket objects and the space occupied by the objects. The size of the object space is a positive integer, measured by bytes.

Because OBS bucket storage statistics are measured in the background, the storage information is not updated in real time. For this reason, you are advised not to perform real-time verification on the storage information.
