如何将保存在 AWS S3 中的 CSV 导出到 DynamoDB？

Question

我看到可以将上传到 s3 的 CSV 直接导入到 dynamodb，但我还没有弄清楚如何正确地执行它。

我猜我的问题可能与我的分区键的命名与我的 csvs 中的实际标头有关，但我不确定。

有没有办法以编程方式轻松地将 CSV 从 s3 导入 dynamodb？

我有 20 个 CSV，我通过 Python 脚本上传到 S3：

import boto3

a_key = '...'
s_key = '...'
region = 'us-west-2'

def upload_to_aws(local_file, bucket, s3_file):
    s3 = boto3.client('s3', aws_access_key_id=a_key,
                          aws_secret_access_key=s_key, region_name=region)
    try:
        s3.upload_file(local_file, bucket, s3_file)
        print("Upload to Cloud Successful")
        return True
    except FileNotFoundError:
        print("The file was not found")
        return False

def snaps(team_name):
    uploaded = upload_to_aws(f'CSVs/{team_name}_snaps.csv', 'teamcsvs', f'CSVs/{team_name}_snaps.csv')

def short(team_name, short_year):
    uploaded = upload_to_aws(f'CSVs/{team_name}{short_year}.csv', 'teamcsvs', f'CSVs/{team_name}{short_year}.csv')

我遵循了本指南并希望我的 CSV 能够无缝地成为 dynamoDB 表，但我的导入一直失败。

我从日志中得到了一些不同的错误，但最新的是：

        "bucket": "teamcsvs",

Answer 1

你没有得到一些不同的错误，你每次都会得到相同的错误。 Item.Score 不明确。
