    use Catmandu::DirectoryIndex::Number;
    my $p = Catmandu::DirectoryIndex::Number->new(
        base_dir => "/data",
        keysize => 9
    );
    # get mapping for id: { _id => 1234, _path => "/data/000/001/234" }
    # can be undef
    my $mapping = $p->get(1234);
    # create mapping for id. Path created if necessary
    my $mapping = $p->add(1234);
    # Catmandu::DirectoryIndex::Number is a Catmandu::Iterable
    # Returns list of records: [{ _id => "000001234", _path => "/data/000/001/234" }]
    my $mappings = $p->to_array();
