DESCRIPTION
Data::Riak::Fast::Bucket is the primary interface that most people will use for Riak. Adding and removing keys and values, adding links, querying keys; all of those happen here.
SYNOPSIS
my $bucket = Data::Riak::Fast::Bucket->new({
name => 'my_bucket',
riak => $riak
});
# Sets the value of "foo" to "bar", in my_bucket.
$bucket->add('foo', 'bar');
# Gets the Result object for "foo" in my_bucket.
my $foo = $bucket->get('foo');
# Returns "bar"
my $value = $foo->value;
$bucket->create_alias({ key => 'foo', as => 'alias_to_foo' });
$bucket->create_alias({ key => 'foo', as => 'alias_to_foo', in => $another_bucket });
# Returns "bar"
my $value = $bucket->resolve_alias('alias_to_foo');
my $value = $another_bucket->resolve_alias('alias_to_foo');
$bucket->add('baz, 'value of baz', { links => [$bucket->create_link( riaktag => 'buddy', key =>'foo' )] });
my $resultset = $bucket->linkwalk('baz', [[ 'buddy', '_' ]]);
my $value = $resultset->first->value; # Will be "bar", the value of foo
METHOD =head2 add ($key, $value, $opts)
This will insert a key $key
into the bucket, with value $value
. The $opts
can include links, allowed content types, or queries.
remove ($key, $opts)
This will remove a key $key
from the bucket.
get ($key, $opts)
This will get a key $key
from the bucket, returning a Data::Riak::Fast::Result object.
list_keys
List all the keys in the bucket. Warning: This is expensive, as it has to scan every key in the system, so don't use it unless you mean it, and know what you're doing.
count
Count all the keys in a bucket. This uses MapReduce to figure out the answer, so it's expensive; Riak does not keep metadata on buckets for reasons that are beyond the scope of this module (but are well documented, so if you are interested, read up).
remove_all
Remove all the keys from a bucket. This involves a list_keys call, so it will be slow on larger systems.
search_index
Searches a Secondary Index to find results.
create_alias ($opts)
Creates an alias for a record using links. Helpful if your primary ID is a UUID or some other automatically generated identifier. Can cross buckets, as well.
$bucket->create_alias({ key => '123456', as => 'foo' });
$bucket->create_alias({ key => '123456', as => 'foo', in => $other_bucket });
resolve_alias ($alias)
Returns the Data::Riak::Fast::Result that $alias points to.
