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 discov‐ ery, 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 fol‐ lowed by a colon character and port number (assumes default port of 6733 if no port is spec‐ ified). To specify a port number with an IPv6 address, enclose the address in square brackets, e.g.: [2001:db8::1]:6733
