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

Configuration option = Default value	Description
allowed_headers = Content-Disposition, Content-Encoding, X-Delete-At, X-Object-Manifest, X-Static-Large-Object	Comma-separated list of headers that can be set in metadata of an object
auto_create_account_prefix = .	Prefix to use when automatically creating accounts
keep_cache_private = false	Allow non-public objects to stay in kernel's buffer cache
keep_cache_size = 5424880	Largest object size to keep in buffer cache
max_upload_time = 86400	Maximum time allowed to upload an object
mb_per_sync = 512	On PUT requests, sync file every n MB
replication_concurrency = 4	Set to restrict the number of concurrent incoming REPLICATION requests; set to 0 for unlimited
replication_failure_ratio = 1.0	If the value of failures / successes of REPLICATION subrequests exceeds this ratio, the overall REPLICATION request will be aborted
replication_failure_threshold = 100	The number of subrequest failures before the replication_failure_ratio is checked
replication_lock_timeout = 15	Number of seconds to wait for an existing replication device lock before giving up.
replication_one_per_device = True	Restricts incoming REPLICATION requests to one per device, replication_currency above allowing. This can help control I/O to each device, but you may wish to set this to False to allow multiple REPLICATION requests (up to the above replication_concurrency setting) per device.
replication_server = false	If defined, tells server how to handle replication verbs in requests. When set to True (or 1), only replication verbs will be accepted. When set to False, replication verbs will be rejected. When undefined, server will accept any verb in the request.
set log_address = /dev/log	Location where syslog sends the logs to
set log_facility = LOG_LOCAL0	Syslog log facility
set log_level = INFO	Log level
set log_name = object-server	Label to use when logging
set log_requests = true	Whether or not to log requests
slow = 0	If > 0, Minimum time in seconds for a PUT or DELETE request to complete
threads_per_disk = 0	Size of the per-disk thread pool used for performing disk I/O. The default of 0 means to not use a per-disk thread pool. It is recommended to keep this value small, as large values can result in high read latencies due to large queue depths. A good starting point is 4 threads per disk.
use = egg:swift#object	Entry point of paste.deploy in the server
