             Summary: S3A : Add option for custom S3 tags while writing and 
deleting S3 objects
                 Key: HADOOP-19536
                 URL: https://issues.apache.org/jira/browse/HADOOP-19536
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/s3
            Reporter: Syed Shameerur Rahman


Custom S3 object 
[tags|https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-tagging.html]
 can be added to S3 objects while writing and deleting.

 

*Use Case:*

S3 tags can be used to categorize the 
[objects|https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-tagging.html]
 and potentially apply bucket level polices to take some actions.

For example : objects can be marked as "to-be-glacier" and based on some bucket 
policy the written objects can be moved to Glacier tier after sometime for cost 
savings.

Apache iceberg's 
[S3FileIO|[https://iceberg.apache.org/docs/nightly/aws/#s3-tags]] also uses S3 
Tags for soft deletes.
