This implementation of the PUT operation uses the tagging subresource to add a set of tags to an existing bucket.
This operation is used to add tags to a bucket. Then, all CDRs generated by the requests for this bucket will take the same tags. Thus, CDR reports can be categorized for detailed cost analysis. For example, data is being uploaded to a bucket when an application is running. The application name can be tagged for this bucket. Use this tag to filter the CDRs generated by this application for analyzing its costs. However, searching for buckets by tag is not supported.
Only users granted the s3:PutBucketTagging permission can perform this operation. By default, the permission is granted to the bucket owner only. However, it can be granted to other users by configuring the bucket policy.
