Object

An object is a fundamental entity in OBS. A bucket can store multiple objects, which may be text files or videos. An object consists of data and metadata. Metadata is used to describe the object data. Metadata stores system information such as the object creation time and object size. It also stores information set by users. In addition, if a user can access the data of an object, the user has the metadata access permission.

A single object can be uploaded with the maximum size of 5 GB. If the size of an object has exceeded 5 GB, multipart upload is required. OBS supports the data size ranging from 0 KB to 48.8 TB.
