.IP "\fBreplication_server\fR"
Configure parameter for creating specific server
To handle all verbs, including replication verbs, do not specify
"replication_server" (this is the default). To only handle replication,
set to a True value (e.g. "True" or "1"). To handle only non-replication
verbs, set to "False". Unless you have a separate replication network, you
should not specify any value for "replication_server".
.IP "\fBreplication_concurrency\fR"
Set to restrict the number of concurrent incoming REPLICATION requests
Set to 0 for unlimited (the default is 4). Note that REPLICATION is currently an ssync only item.
.IP "\fBreplication_one_per_device\fR"
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. The default is true.
.IP "\fBreplication_lock_timeout\fR"
Number of seconds to wait for an existing replication device lock before
giving up. The default is 15.
.IP "\fBreplication_failure_threshold\fR"
.IP "\fBreplication_failure_ratio\fR"
These two settings control when the REPLICATION subrequest handler will
abort an incoming REPLICATION attempt. An abort will occur if there are at
least threshold number of failures and the value of failures / successes
exceeds the ratio. The defaults of 100 and 1.0 means that at least 100
failures have to occur and there have to be more failures than successes for
an abort to occur.
.IP "\fBsplice\fR"
Use splice() for zero-copy object GETs. This requires Linux kernel
version 3.0 or greater. If you set "splice = yes" but the kernel
does not support it, error messages will appear in the object server
logs at startup, but your object servers should continue to function.

The reseller_prefix option lists account namespaces that this middleware is

For example, for project 12345678, and prefix AUTH, the account is
named AUTH_12345678 (i.e., path is /v1/AUTH_12345678/...).
Several prefixes are allowed by specifying a comma-separated list
as in: "reseller_prefix = AUTH, SERVICE". The empty string indicates a
single blank/empty prefix. If an empty prefix is required in a list of
prefixes, a value of '' (two single quote characters) indicates a
blank/empty prefix. Except for the blank/empty prefix, an underscore ('_')
character is appended to the value unless already present.

the parameter SERVICE_operator_roles applies to the /v1/SERVICE_<project>
path). If you omit the prefix, the option applies to all reseller
prefix items. For the blank/empty prefix, prefix with '' (do not put

Using timing measurements may allow for lower overall latency, while

affinity cases, equally-sorting nodes are still randomly chosen to
spread load.
