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
