一个人应该使用实体查询而不是直接对数据库进行操作：

One should use entity queries instead of acting directly on the database:

  $result = \Drupal::entityQuery('node')
      ->condition('type', 'my_content_type_name')
      ->execute();
  entity_delete_multiple('node', $result);

像其他答案中那样设置范围应该不太困难。

Setting up ranges like in the other answer shouldn't be too difficult.
