Object Tag Overview

Last updated: 2022-08-30 14:55:18

    Overview

    Object tagging is designed to help you group and manage objects in your bucket by adding a key-value pair as an object tag. An object tag consists of a tagKey, a =, and a tagValue, such as group = IT. You can set, query, and delete tags on the specified object.

    Note:

    Object tagging is a paid feature. For detailed pricing, see Pricing | Cloud Object Storage.
