%% cluster_name can be any short string; it should be the same for all
%%  nodes that will be participating in the same cluster.
{cluster_name, "default"}.
%% ring_state_dir is where ring membership information will be stored.
{ring_state_dir, "priv/ringstate"}.
%% ring_creation_size determines the number of partitions used for hashing
%%  document keys.  This cannot be changed after cluster initialization.
%%  Ensure that it is at least 10x the number of hosts you might ever
%%  add to the cluster.
%% note: make sure you configure your operating system limits for maximum
%% open files (using ulimit/sysctl) when creating larger ring sizes. 
{ring_creation_size, 16}.
%% gossip_interval (milliseconds) is the frequency of gossip messages.
%%  Making it larger will reduce chatter, but will cause greater delays
%%  in ring convergence between nodes.
{gossip_interval, 60000}.
%% storage_backend specifies the Erlang module defining the storage mechanism
%%  that will be used on this node. 
{storage_backend, riak_dets_backend}.
%% Different storage backends can use other configuration variables.  For
%%  instance, riak_dets_backend_root determines the directory under which
%%  dets files will be placed.
{riak_dets_backend_root, "/path/to/riak/store"}.
%% riak_cookie is the Erlang cookie that the cluster shares.  This must be
%%  the same across all nodes.
{riak_cookie, default_riak_cookie}.
%% riak_heart_command will be used by heart to restart the system in case of
%%  a lockup or certain types of crashes.  Make sure to fix the paths in
%%  the command if you wish for automatic restarts to work.
{riak_heart_command, "(cd /path/to/riak; ./start-restart.sh /path/to/riak/config/riak.erlenv)"}.
%% riak_nodename is the first part of the name that this node will use to
%%  identify itself.  This must be different for all ndoes with the same
%%  value of riak_hostname.
{riak_nodename, riak}.
%% riak_hostname is the second part of the name that this node will use to
%%  identify itself.  This must be an IP or hostname that the other nodes
%%  can use to contact the system.
{riak_hostname, "127.0.0.1"}.
%% riak_web_ip is the IP address that Riak's HTTP interface will bind to.
%%  If this is undefined, the HTTP interface will not run.
{riak_web_ip, "127.0.0.1"}.
%% riak_web_port is the TCP port that Riak's HTTP interface will bind to.
{riak_web_port, 8098}.
%% jiak_name is the first part of all URLs used by Riak's JSON HTTP interface.
%%  See the JSON HTTP interface documents for more details.  If you change this,
%%  the defaults used by some Riak HTTP clients may not work.
{jiak_name, "jiak"}.
%% raw_name is the first part of all URLS used by Riak's raw HTTP interface.
%%  See riak_web.erl and raw_http_resource.erl for details.
{raw_name, "raw"}.
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
