Object expiration

=================

|
You can schedule Object Storage (swift) objects to expire by setting the
|
||
|
|
``X-Delete-At`` or ``X-Delete-After`` header. Once the object is deleted,
|
||
|
|
swift will no longer serve the object and it will be deleted from the cluster
|
||
|
|
shortly thereafter.
|
||
|
|
|
||
|
|
* Set an object to expire at an absolute time (in Unix time). You
|
||
|
|
can get the current Unix time by running ``date +'%s'``.
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ swift post CONTAINER OBJECT_FILENAME -H "X-Delete-At:UNIX_TIME"
|
||
|
|
|
||
|
|
Verify the ``X-Delete-At`` header has posted to the object:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ swift stat CONTAINER OBJECT_FILENAME
|
||
|
|
|
||
|
|
* Set an object to expire after a relative amount of time (in seconds):
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ swift post CONTAINER OBJECT_FILENAME -H "X-Delete-After:SECONDS"
|
||
|
|
|
||
|
|
The ``X-Delete-After`` header will be converted to ``X-Delete-At``.
|
||
|
|
Verify the ``X-Delete-At`` header has posted to the object:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ swift stat CONTAINER OBJECT_FILENAME
|
||
|
|
|
||
|
|
If you no longer want to expire the object, you can remove the
|
||
|
|
``X-Delete-At`` header:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ swift post CONTAINER OBJECT_FILENAME -H "X-Remove-Delete-At:"
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
In order for object expiration to work properly, the
|
||
|
|
``swift-object-expirer`` daemon will need access to all backend
|
||
|
|
servers in the cluster. The daemon does not need access to the
|
||
|
|
proxy-server or public network.
