Description of configuration options for [object-expirer] in object-expirer.conf

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 :ref:`server-per-port-configuration`.
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.
