NAME

Ceph::Rados - Perl wrapper to librados.

SYNOPSIS

            

              
              
use Ceph::Rados;
my $cluster = Ceph::Rados->new('admin');
$cluster->set_config_file;
$cluster->set_config_option( keyring => '/etc/ceph/ceph.client.admin.keyring');
$cluster->connect;
my $io = $cluster->io('testing_pool');
$io->write('greeting', 'hello');
my $stored_data = $io->read('greeting',10);
my ($len, $mtime) = $io->stat('greeting');
$io->delete('greeting');
my $list = $io->list;
while (my $entry = $list->next) {
    print "Found $entry\n";
}
            
          

DESCRIPTION

This module provides a very limited subset of the librados API, currently just read/write/stat and lists.

If no length is passed to the read() call, the object is first stat'd to determine the correct read length.

METHODS

set_config_file()

Wraps rados_conf_read_file(). If not passed a path, the following locations are tried, in order:

$ENV{CEPH_CONF}

/etc/ceph/ceph.conf

~/.ceph/config

./ceph.conf

set_config_option()

Wraps rados_conf_set(). Typically used to set the keyring.

connect()

Wraps rados_connect(). Connects to the rados cluster, using the config provided.

io()

Wraps rados_ioctx_create(). Opens an IO context to the specified pool. Returns a Ceph::Rados::IO object.
