python - 如何在 cassandra 中声明地图定义类型的列表

Question

我想在 cassandra 中声明一个对象列表，并且我已经创建了类型对象

CREATE TYPE profiles.educations (
    major text,
    end text,
    name text,
    degree text,
    start text,
    desce text
);

如何声明地图教育类型列表，因为我有一个这种格式的 json 文件：

{
...
"educations": [
    {
      "start": "2009",
      "major": "Business Administration and Management, General",
      "end": "2010",
      "name": "Gordon Institute of Business Science - University of Pretoria",
      "degree": "PDBA"
    },
    {
      "start": "2002",
      "major": "Marketing Management",
      "end": "2006",
      "name": "University of Pretoria/Universiteit van Pretoria",
      "degree": "B. com with specialization in Marketing Management"
    },
    {
      "major": "Finanzas",
      "end": "2013",
      "name": "Universidad de Los Andes",
      "degree": "Maestr\u00eda en Finanzas",
      "start": "2011",
      "desce": ""
    }]
...
}
