Overview

Object Tagging is designed to help you group and manage objects in your bucket by adding a key-value pair as object identifier. 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.

You will be billed for using this feature. For more information on its pricing, see Product Pricing.
