Steve Loughran commented on HADOOP-19536:
-----------------------------------------
* would this be a bucket setting?
* or in file creation
tags can be changed, cant they? which means the xattr api should be used to get
at them.
* we already use xattr to read headers (though we got the naming of those attrs
wrong in a way which complicates some apps)
* we could extend this to allow get *and set* of tags
> 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
> Priority: Major
>
> 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|#s3-tags]] also uses S3 Tags for soft deletes.
