=head2 Attributes

=over

=item schema

The DBIx::Class schema

=item resultset

The DBIx::Class ResultSet which will be use to operate on the database table.
Internally the calls will be $self->schema->($self->resultset) etc.

=item column_map

A hash ref with the keys key, data and expires_in. Used to map to the table columns.
Defaults to:

        {
            key        => 'id',
            data       => 'session_data',
            expires_in => 'timestamp'
        }
