.TH Net::OpenDHT 3 "2008-01-13" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
Net::OpenDHT \- Access the Open Distributed Hash Table (Open DHT)
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 3
\&  my $dht = Net::OpenDHT->new();
\&  $dht->application("My Application");
\&  $dht->server($server); # see below
.Ve

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The Net::OpenDHT module provides a simple interface to the Open \s-1DHT\s0
service. Open \s-1DHT\s0 is a publicly accessible distributed hash table (\s-1DHT\s0)
service. In contrast to the usual \s-1DHT\s0 model, clients of Open \s-1DHT\s0 do not
need to run a \s-1DHT\s0 node in order to use the service. Instead, they can
issue put and get operations to any \s-1DHT\s0 node, which processes the
operations on their behalf. No credentials or accounts are required to
use the service, and the available storage is fairly shared across all
active clients.
.PP
This service model of \s-1DHT\s0 usage greatly simplifies deploying client
applications. By using Open \s-1DHT\s0 as a highly-available naming and storage
service, clients can ignore the complexities of deploying and
maintaining a \s-1DHT\s0 and instead concentrate on developing more
sophisticated distributed applications.
.PP
What this essentially gives you as a Perl author is robust storage for a
small amount of data. This can be used as a distributed cache or data
store.

.SH "METHODS"
.IX Header "METHODS"
.Sh "new"
.IX Subsection "new"
The constructor:
.PP
.Vb 1
\&  my $dht = Net::OpenDHT->new();
.Ve
.Sh "application"
.IX Subsection "application"
The application method sets the name of the application. You should set
this as a courtesy to the Open \s-1DHT\s0 developers:
.PP
.Vb 1
\&  $dht->application("My Application");
.Ve
.Sh "fetch"
.IX Subsection "fetch"
The get method fetches data from the Open \s-1DHT\s0. Note that multiple values
can be set for a key:
.PP
.Vb 2
\&  my $value  = $dht->fetch($key);
\&  my @values = $dht->fetch($key);
.Ve
.Sh "put"
.IX Subsection "put"
The put method puts data into the Open \s-1DHT\s0. The key has a maximum length
of 20 bytes, the value a maximum length of 1024 bytes. You must also
pass in a time to live in seconds:
.PP
.Vb 1
\&  $dht->put($key, $value, $ttl);
.Ve
.Sh "server"
.IX Subsection "server"
The module automatically finds a topologically-close gateway to the
\&\s-1DHT\s0 via the CoralCDN \s-1OASIS\s0 service. You may override this and provide
your own gateway with this method:
.PP
.Vb 1
\&  $dht->server($server);
