NAME

Net::Riak::Bucket - Access and change information about a Riak bucket

VERSION

version 0.11

SYNOPSIS

    my $client = Net::Riak->new(...);
    my $bucket = $client->bucket('foo');

    # retrieve an existing object
    my $obj1 = $bucket->get('foo');

    # create/store a new object
    my $obj2 = $bucket->new_object('foo2', {...});
    $object->store;

DESCRIPTION

The Net::Riak::Bucket object allows you to access and change information about a Riak bucket, and provides methods to create or retrieve objects within the bucket.

ATTRIBUTES

name

    my $name = $bucket->name;

Get the bucket name

r

    my $r_value = $bucket->r;

R value setting for this client (default 2)

w

    my $w_value = $bucket->w;

W value setting for this client (default 2)

dw

    my $dw_value = $bucket->dw;

DW value setting for this client (default 2)

METHODS

new_object

    my $obj = $bucket->new_object($key, $data, @args);

Create a new Net::Riak::Object object. Additional Object constructor arguments can be passed after $data. If $data is a reference and no explicit Object content_type is given in @args, the data will be serialised and stored as JSON.

get

    my $obj = $bucket->get($key, [$r]);

Retrieve an object from Riak.

n_val

    my $n_val = $bucket->n_val;

Get/set the N-value for this bucket, which is the number of replicas that will be written of each object in the bucket. Set this once before you write any data to the bucket, and never change it again, otherwise unpredictable things could happen. This should only be used if you know what you are doing.

allow_multiples

    $bucket->allow_multiples(1|0);

If set to True, then writes with conflicting data will be stored and returned to the client. This situation can be detected by calling has_siblings() and get_siblings(). This should only be used if you know what you are doing.

get_keys

    my $keys = $bucket->get_keys;
    my $keys = $bucket->get_keys($args);

Return an arrayref of the list of keys for a bucket. Optionally takes a hashref of named parameters. Supported parameters are:

stream => 1

Uses key streaming mode to fetch the list of keys, which may be faster for large keyspaces.

cb => sub { }

A callback subroutine to be called for each key found (passed in as the only parameter). get_keys() returns nothing in callback mode.

set_property

    $bucket->set_property({n_val => 2});

Set a bucket property. This should only be used if you know what you are doing.

get_property

    my $prop = $bucket->get_property('n_val');

Retrieve a bucket property.

set_properties

Set multiple bucket properties in one call. This should only be used if you know what you are doing.

get_properties

Retrieve an associative array of all bucket properties, containing 'props' and 'keys' elements.

Accepts a hashref of parameters. Supported parameters are:

props => 'true'|'false'

Whether to return bucket properties. Defaults to 'true' if no parameters are given.

keys => 'true'|'false'|'stream'

Whether to return bucket keys. If set to 'stream', uses key streaming mode, which may be faster for large keyspaces.

cb => sub { }

A callback subroutine to be called for each key found (passed in as the only parameter). Implies keys => 'stream'. Keys are omitted from the results hashref in callback mode.
