NAME
4store.conf — 4store configuration file
DESCRIPTION
The file /etc/4store.conf contains settings used by 4s-admin(1), 4s-boss(8), 4s-httpd, 4s-import(1) and
4s-query(1).
File format
The config file uses GLib's key file format, which contains key-value pairs organised into groups. The
syntax of the file is as follows:
Blank lines or beginning with a hash character are considered comments:
# this is a comment
Groups are defined by enclosing a group name within square brackets:
[first group]
[group2]
Each key-value pair must be placed on a new line, and will belong to the group above it.
A key-value pair is specified using 'key=values', where values can be a semicolon separated list of
strings:
[group1]
ids=1;2;3
people=Alice;Bob
[group2]
disable_foo=false
Store options
These are options which will affect the running of 4s-backend and 4s-httpd.
To set them for all stores, place them in an option group named [default].
To set them on a single store, place them in an option group with the same name as the store, e.g.
[store1].
Options:
unsafe = true|false
Enable unsafe operations (such as LOAD). Default is false.
cors = true|false
Enables CORS. Default is false.
port = <port_number>
Port to run HTTP SPARQL daemon (4s-httpd) on. Default is 8080.
default-graph = true|false
Set the default graph to be a union of named graphs. Default is false.
soft-limit = <limit>
Sets the soft limit, or set to 0 to disable. Default is 2000.
opt-level = <level>
Set the optimisation level, from 0 to 3. Default is 3 (all optimisations enabled).
listen = <hostname>|<ip_address>
The hostname or IP address that 4s-httpd should listen on. Default is localhost.
4s-boss options
These options are used to configure 4s-boss(8), and set how and if it should be used for store discovery.
These options should all be in a group named [4s-boss].
Options:
port = <port_number>
Set port to run 4s-boss daemon on. Default is 6733.
discovery = none|sole|default
Determines how 4s-boss is used for store discovery. Default is none.
nodes = <hostname_or_ip>[:<port>];...
List of nodes in the cluster which run 4s-boss. Default is localhost.
Set discovery to none to use Avahi/DNS-SD for discovery instead of 4s-boss. Set to sole to use 4s-boss
as the only discovery mechanism. Set to default to use use 4s-boss for discovery, but fall back to
Avahi/DNS-SD.
The nodes option sets the hosts and ports of storage nodes in a 4store cluster that uses 4s-boss. Hosts
can be specified either as hostnames or IPv4/IPv6 addresses, optionally followed by a colon character and
port number (assumes default port of 6733 if no port is specified).
To specify a port number with an IPv6 address, enclose the address in square brackets, e.g.:
[2001:db8::1]:6733
