  /**
   * A temporary UDT implementation that only contains the keyspace and name.
   *
   * <p>When we refresh a keyspace's UDTs, we can't fully materialize them right away, because they
   * might depend on each other and the system table query does not return them in topological order.
   * So we do a first pass where UDTs that are nested into other UDTsare resolved as instances of this
   * class, then a topological sort, then a second pass to replace all shallow definitions by the
   * actual instance (which will be a {@link DefaultUserDefinedType}).
   *
   * <p>This type is also used in the schema builder's internal representation: the keyspace, name and
   * frozen-ness are the only things we need to generate a query string.
