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

Configuration option = Default value	Description
concurrency = 1	Number of replication workers to spawn
daemonize = on	Whether or not to run replication as a daemon
handoff_delete = auto	By default handoff partitions will be removed when it has successfully replicated to all the canonical nodes. If set to an integer n, it will remove the partition if it is successfully replicated to n nodes. The default setting should not be changed, except for extremem situations. This uses what's set here, or what's set in the DEFAULT section, or 10 (though other sections use 3 as the final default).
handoffs_first = False	If set to True, partitions that are not supposed to be on the node will be replicated first. The default setting should not be changed, except for extreme situations.
http_timeout = 60	Maximum duration for an HTTP request
interval = 30	Minimum time for a pass to take
lockup_timeout = 1800	Attempts to kill all workers if nothing replications for lockup_timeout seconds
log_address = /dev/log	Location where syslog sends the logs to
log_facility = LOG_LOCAL0	Syslog log facility
log_level = INFO	Logging level
log_name = object-replicator	Label used when logging
node_timeout = <whatever's in the DEFAULT section or 10>	Request timeout to external services
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
ring_check_interval = 15	How often (in seconds) to check the ring
rsync_bwlimit = 0	bandwidth limit for rsync in kB/s. 0 means unlimited
rsync_compress = no	Allows rsync to compress data which is transmitted to the destination node during sync. However, this applies only when the destination node is in a different region than the local one. Note Objects that are already compressed (for example: .tar.gz, .mp3) might slow down the syncing process.
rsync_error_log_line_length = 0	Limits the length of the rsync error log lines. 0 will log the entire line.
rsync_io_timeout = 30	Passed to rsync for a max duration (seconds) of an I/O op
rsync_module = {replication_ip}::object	Format of the rsync module where the replicator will send data. The configuration value can include some variables that will be extracted from the ring. Variables must follow the format {NAME} where NAME is one of: ip, port, replication_ip, replication_port, region, zone, device, meta. See etc/rsyncd.conf-sample for some examples. uses what's set here, or what's set in the DEFAULT section, or 10 (though other sections use 3 as the final default).
rsync_timeout = 900	Max duration (seconds) of a partition rsync
run_pause = 30	Time in seconds to wait between replication passes
stats_interval = 300	Interval in seconds between logging replication statistics
sync_method = rsync	default is rsync, alternative is ssync
