Question

我正在尝试在mongodb集合中导入以下数据

[
{"_id":NumberLong(1), "name": "Afghanistan", "code": "AF"},
{"_id":NumberLong(2), "name": "Aland Islands", "code": "AX"},
{"_id":NumberLong(3), "name": "Albania", "code": "AL"},
{"_id":NumberLong(4), "name": "Algeria", "code": "DZ"},
{"_id":NumberLong(5), "name": "American Samoa", "code": "AS"},
{"_id":NumberLong(6), "name": "AndorrA", "code": "AD"}
]

我收到错误 -

我假设您向我们展示了数据的缩写。错误表明您的JSON产生的BSON超过了16MB的硬限制。您可以通过重新格式化数据来解决问题。不是将多个文档放在一个数组中并使用--jsonArray导入，这会将总导入大小限制为16MB，而是每行放一个json文档：

{"_id":NumberLong(1), "name": "Afghanistan", "code": "AF"},
{"_id":NumberLong(2), "name": "Aland Islands", "code": "AX"},
{"_id":NumberLong(3), "name": "Albania", "code": "AL"},
{"_id":NumberLong(4), "name": "Algeria", "code": "DZ"},
{"_id":NumberLong(5), "name": "American Samoa", "code": "AS"},
{"_id":NumberLong(6), "name": "AndorrA", "code": "AD"}
...

Mongodb用_id导入json
