.. list-table:: Description of configuration options for ``[object-expirer]`` in ``object-expirer.conf``
:header-rows: 1
:class: config-ref-table
* - Configuration option = Default value
- Description
* - ``auto_create_account_prefix`` = ``.``
- Prefix to use when automatically creating accounts
* - ``concurrency`` = ``1``
- Number of replication workers to spawn
* - ``expiring_objects_account_name`` = ``expiring_objects``
- No help text available for this option.
* - ``interval`` = ``300``
- Minimum time for a pass to take
* - ``process`` = ``0``
- (it will actually accept(2) N + 1). Setting this to one (1) will only handle one request at a time, without accepting another request concurrently.
* - ``processes`` = ``0``
- for each port (disk) in the ring. If you have 24 disks per server, and this setting is 4, then each storage node will have 1 + (24 * 4) = 97 total object-server processes running. This gives complete I/O isolation, drastically reducing the impact of slow disks on storage node performance. The object-replicator and object-reconstructor need to see this setting too, so it must be in the [DEFAULT] section. See
* - ``reclaim_age`` = ``604800``
- Time elapsed in seconds before an object can be reclaimed
* - ``recon_cache_path`` = ``/var/cache/swift``
- Directory where stats for a few items will be stored
* - ``report_interval`` = ``300``
- No help text available for this option.
