我在cassandra中呈现复杂的数据结构时遇到问题. JSON数据示例:

{
  "A": {
    "A_ID" : "1111"
    "field1": "value1",
    "field2": "value2",
    "field3": [
      {
        "id": "id1",
        "name": "name1",
        "segment": [
          {
            "segment_id": "segment_id_1",
            "segment_name": "segment_name_1",
            "segment_value": "segment_value_1"
          },
          {
            "segment_id": "segment_id_2",
            "segment_name": "segment_name_2",
            "segment_value": "segment_value_2"
          },
          ...
        ]
      },
      {
        "id": "id2",
        "name": "name2",
        "segment": [
          {
            "segment_id": "segment_id_3",
            "segment_name": "segment_name_3",
            "segment_value": "segment_value_3"
          },
          {
            "segment_id": "segment_id_4",
            "segment_name": "segment_name_4",
            "segment_value": "segment_value_4"
          },
          ...
        ]
      },
      ...
    ]
  }
}

将仅使用一个查询: 按A_ID查找.

我认为这些数据应该存储在一个TABLE(列族)中,而不需要序列化/反序列化操作,以提高效率.如果CQL不支持嵌套地图和列表,我该怎么做？
