=head1 SYNOPSIS
my $client = Net::Riak->new(
host => 'http://10.0.0.40:8098',
ua_timeout => 900
);
my $bucket = $client->bucket('blog');
my $obj = $bucket->new_object('new_post', {title => 'foo', content => 'bar'});
$obj->store;
$obj = $bucket->get('new_post');
say "title for ".$obj->key." is ".$obj->data->{title};
my $req = $client->http_request; # last request
$client->http_response # last response
=head1 DESCRIPTION
=head2 ATTRIBUTES
=over 4
=item B<host>
URL of the node (default 'http://127.0.0.1:8098'). If your ring is composed with more than one node, you can configure the client to hit more than one host, instead of hitting always the same node. For this, you can do one of the following:
=over 4
=item B<all nodes equals>
my $riak = Net::Riak->new(
host => [
'http://10.0.0.40:8098',
'http://10.0.0.41:8098'
]
);
=item B<give weight to nodes>
my $riak = Net::Riak->new(
host => [
{node => 'http://10.0.0.40:8098', weight => '0.2'},
{node => 'http://10.0.0.41:8098', weight => '0.8'}
]
);
=back
Now, when a request is made, a node is picked at random, according to weight.
=item B<prefix>
Interface prefix (default 'riak')
=item B<mapred_prefix>
MapReduce prefix (default 'mapred')
=item B<r>
R value setting for this client (default 2)
=item B<w>
W value setting for this client (default 2)
=item B<dw>
DW value setting for this client (default 2)
=item B<client_id>
client_id for this client
=back
=item B<ua_timeout>
timeout for L<LWP::UserAgent> in seconds, defaults to 3.
=head1 METHODS
=head2 bucket
my $bucket = $client->bucket($name);
Get the bucket by the specified name. Since buckets always exist, this will always return a L<Net::Riak::Bucket>
=head2 is_alive
if (!$client->is_alive) {
...
}
Check if the Riak server for this client is alive
=head2 add
my $map_reduce = $client->add('bucket_name', 'key');
Start assembling a Map/Reduce operation
=head2 link
my $map_reduce = $client->link();
Start assembling a Map/Reduce operation
=head2 map
my $map_reduce = $client->add('bucket_name', 'key')->map("function ...");
Start assembling a Map/Reduce operation
=head2 reduce
my $map_reduce = $client->add(..)->map(..)->reduce("function ...");
Start assembling a Map/Reduce operation
=method http_request
Returns the HTTP::Request object from the last request
=method http_response
Returns a HTTP::Response object from the last request
