Amazon dynamodb 从JSON或CSV将50K记录加载到DynamoDB

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50K记录加载到DynamoDB中。我不知道我哪里做错了。目前看来，我一次最多可以加载25条记录，这是一个非常长的过程，要将所有50K记录加载到DynamoDB中

JSON文件大小约为70MB

有没有办法从保存对象数组的JSON加载所有50K记录？或者以任何方式从CSV加载？我能够从java代码加载。但我主要是寻找一些dynamodb命令或工具，我应该能够加载它们

一个JSON对象如下所示：

"PutRequest": { 
    "Item": { 
        "id": {"S":"1"},
        "zipcode": {"S":"501"},
        "city": {"S":"HOLTSVILLE"},
        "state": {"S":"NY"},
        "county_name": {"S":"SUFFOLK"},
        "area_codes": {"S":"631"},
        "city_type": {"S":"Non Postal Community Name"},
        "city_abbr": {"S":""},
        "city_alias": {"S":"I R S SERVICE CENTER"},
        "latitude": {"S":"40.81518"},
        "longitude": {"S":"-73.0455"},
        "time_zone_offset": {"S":"5"},
        "elevation": {"S":"25"},
        "county_fips": {"S":"103"},
        "daylight_savings_flag": {"S":"Y"},
        "preferred_last_line_key": {"S":"V13916"},
        "classification_code": {"S":"U"},
        "multi_county_flag": {"S":" "},
        "state_fips": {"S":"36"},
        "city_state_key": {"S":"V13995"},
        "time_zone": {"S":"America/New_York"},
        "daylight_savings": {"S":"1"},
        "updated_at": {"S":"2/26/2009 0:00"},
        "city_alias_code": {"S":"NULL"},
        "primary_record": {"S":"NULL"},
        "city_mixed_case": {"S":"NULL"},
        "city_alias_mixed_case": {"S":"NULL"},
        "state_ansi": {"S":"NULL"},
        "county_ansi": {"S":"NULL"},
        "facility_code": {"S":"NULL"},
        "unique_zip_name": {"S":"NULL"},
        "city_delivery_indicator": {"S":"NULL"},
        "carrier_route_rate_sortation": {"S":"NULL"},
        "finance_number": {"S":"NULL"},
        "unique_id": {"S":"NULL"},
        "created_at": {"S":"NULL"},
        "country_code": {"S":"US"}
    }
}
