Now you do not need to maintain processes to periodically identify S3 objects, which are not required any longer and issue delete requests for such objects.
Amazon S3 announced Object Expiration feature recently, which allows you to set up rules to schedule delete requests for objects after a defined time period. You can define Object Expiration rules for a set of objects in a bucket and automatically queue such objects for deletion. This could be a huge time and cost saver for you.
The latest version of Bucket Explorer offers an easy to use user interface for Object Expiration feature. You can set the object life-cycle for selected remote path and objects using Bucket Explorer and enable or disable that rule. You can set expiration time for the objects in days. The expiration period specifies the number of days from the date of creation after which the objects should be deleted.
You can define a prefix to identify the set of objects on which the expiration rule is to be applied.
There is no additional charge of using Object Expiration feature of Amazon S3.
