From 2014cdb9066e273cf791f38b1c8247427c76cfa9 Mon Sep 17 00:00:00 2001 From: Prashanth Pai Date: Tue, 28 Jan 2014 12:13:33 +0530 Subject: Add support for Object Expiration feature Preventing access to expired objects ------------------------------------ Re-enabled accepting X-Delete-At and X-Delete-After headers. During a GET on an expired object, DiskFileExpired is raised by DiskFile class. This will result in object-server returning HTTPNotFound (404) to the client. Tracking objects to be deleted ------------------------------ Objects to be deleted are tracked using "tracker objects". These are PUT into a special account(a volume, for now). These zero size "tracker objects" have names that contain: * Expiration timestamp * Path of the actual object to be deleted Deleting actual objects from GlusterFS volume --------------------------------------------- The object-expirer daemon runs a pass once every X seconds. For every pass it makes, it queries the special account for "tracker objects". Based on (timestamp, path) present in name of "tracker objects", object-expirer then deletes the actual object and the corresponding tracker object. To run object-expirer forever: swift-init object-expirer start To run just once: swift-object-expirer -o -v /etc/swift/object-expirer.conf Caveat/Limitation: Object-expirer needs a separate account(volume) that is not used by other services like gswauth. By default, this volume is named "gsexpiring" and is configurable.
