Jubatus - Perl extension for interfacing with Jubatus, a distributed processing framework and streaming machine learning library.
use Jubatus; my $cluster_name = "jubatus_perl_doc"; # even if it isn't in a distributed environment using ZooKeeper and Jubatus keepers. my $host_name_or_ip_address = "localhost"; # master node's my $port_number_of_juba_process = 13714; # meanless my $juba_client_type = "stat"; # you can select from (recommender|regression|classifier|stat|graph|anomaly) my $graph_client = Jubatus->get_client($host_name_or_ip_address, $port_number_of_juba_process, $juba_client_type); # got Jubatus::Stat::Client object # In the following example, get maximum value from sample array using Jubatus::Stat::Client object my @sample = (1.0, 2.0, 3.0, 4.0, 5.0); my $key = "sum"; foreach my $val (@sample) { my $is_push = $stat_client->push($cluster_name, $key, $val); } my $result = $stat_client->sum($cluster_name, $key); # $result is 15.0
This module provide a interface of Jubatus by TCP-based MessagePack RPC protocol using AnyEvent::MPRPC::Client Jubatus is a distributed processing framework and streaming machine learning library.
Jubatus provide you a couple of export functions that are shortcut of Jubatus::Recommender::Client and Jubatus::Regression::Client, Jubatus::Classifier::Client, Jubatus::Stat::Client, Jubatus::Graph::Client, Jubatus::Anomaly::Client, Jubatus:;NearestNeighbor::Client,
One is get_client to get Client object by specifying client type. Another is get_recommender_client and get_regression_client, get_classifier_client, get_stst_client, get_graph_client, get_anomaly_client, get_nearestneighbor_client to get a specific Client object explicitly.
get_client
get_recommender_client
get_regression_client
get_classifier_client
get_stst_client
get_graph_client
get_anomaly_client
get_nearestneighbor_client
$juba_client_type is a value to specify the client type of jubatus. You can select from (recommender|regression|classifier|stat|graph|anomaly). You can also use (Recommender|Regression|Classifier|Stat|Graph|Anomaly).
If you select 'stat', you can get Jubatus::Stat::Client object.
my $host = 'localhost'; my $port = '13714'; my $juba_client_type = 'stat'; my $stat_client = Jubatus->get_client($host, $port, $juba_client_type);
This code will create Jubatus::Stat::Client object and return it. You should set $host and $port in agreement to running jubastat server application.
The above code is equivalent to:
use Jubatus::Stat::Client; my $host = 'localhost'; my $port = '13714'; Jubatus::Stat::Client->new($host, $port);
This code will create Jubatus::Recommener::Client object and return it. You should set $host and $port in agreement to running jubarecommender server application.
my $host = 'localhost'; my $port = '13714'; my $stat_client = Jubatus->get_recommender_client($host, $port);
use Jubatus::Recommender::Client; my $host = 'localhost'; my $port = '13714'; Jubatus::Recommender::Client->new($host, $port);
See Jubatus::Recommender::Client for more detail.
This code will create Jubatus::Regression::Client object and return it. You should set $host and $port in agreement to running jubaregression server application.
my $host = 'localhost'; my $port = '13714'; my $stat_client = Jubatus->get_regression_client($host, $port);
use Jubatus::Regression::Client; my $host = 'localhost'; my $port = '13714'; Jubatus::Regression::Client->new($host, $port);
See Jubatus::Regression::Client for more detail.
This code will create Jubatus::Classifier::Client object and return it. You should set $host and $port in agreement to running jubaclassifier server application.
my $host = 'localhost'; my $port = '13714'; my $stat_client = Jubatus->get_classifier_client($host, $port);
use Jubatus::Classifier::Client; my $host = 'localhost'; my $port = '13714'; Jubatus::Classifier::Client->new($host, $port);
See Jubatus::Classifier::Client for more detail.
my $host = 'localhost'; my $port = '13714'; my $stat_client = Jubatus->get_stat_client($host, $port);
See Jubatus::Stat::Client for more detail.
This code will create Jubatus::Graph::Client object and return it. You should set $host and $port in agreement to running jubagraph server application.
my $host = 'localhost'; my $port = '13714'; my $graph_client = Jubatus->get_graph_client($host, $port);
use Jubatus::Graph::Client; my $host = 'localhost'; my $port = '13714'; Jubatus::Graph::Client->new($host, $port);
See Jubatus::Graph::Client for more detail.
This code will create Jubatus::Anomaly::Client object and return it. You should set $host and $port in agreement to running jubaanomaly server application.
my $host = 'localhost'; my $port = '13714'; my $anomaly_client = Jubatus->get_anomaly_client($host, $port);
use Jubatus::Anomaly::Client; my $host = 'localhost'; my $port = '13714'; Jubatus::Anomaly::Client->new($host, $port);
See Jubatus::Anomaly::Client for more detail.
This code will create Jubatus::NearestNeighbor::Client object and return it. You should set $host and $port in agreement to running jubanearest_neighbor server application.
my $host = 'localhost'; my $port = '13714'; my $nearest_neighbor_client = Jubatus->get_nearestneighbor_client($host, $port);
use Jubatus::NearestNeighbor::Client; my $host = 'localhost'; my $port = '13714'; Jubatus::NearestNeighbor::Client->new($host, $port);
See Jubatus::NearestNeighbor::Client for more detail.
