从JSON或CSV将50K条记录加载到DynamoDB

Question

我有一个csv或50K记录以及50K记录的JSON文档。文件或文档是一组地理位置。

我的目标是将所有50万条记录加载到DynamoDB中。我不知道我哪里做错了。目前，我一次最多可以加载25条记录，这是一个将所有50万条记录加载到DynamoDB的漫长过程。

JSON文件大小约为70 MB。

有什么方法可以从保存对象数组的JSON中加载所有50K记录吗？或者以任何方式从CSV加载？我能够从java代码进行加载。但我主要是在寻找一些发电机命令或工具，我应该能够加载。

一个JSON对象如下所示：

"PutRequest": { 
"Item": { 
"id": {"S":"1"},
"zipcode": {"S":"501"},
"city": {"S":"HOLTSVILLE"},
"state": {"S":"NY"},

"finance_number": {"S":"NULL"},
"unique_id": {"S":"NULL"},

}
}

提前谢谢。
