使用Python删除DynamoDB的所有项目

问题描述

如何使用python（boto3）从DynamoDB中删除所有项目？

How can I delete all items from DynamoDB using python (boto3)?

我正在尝试这样做：

scan = table.scan()
with table.batch_writer() as batch:
  for each in scan['Items']:
    batch.delete_item(Key=each)

但是给我这个错误：

botocore.exceptions.ClientError: An error occurred (ValidationException) when calling the BatchWriteItem operation: The provided key element does not match the schema

推荐答案

我找到了解决方案！我只是在表ID和搜索ID（compId）上安装了密钥，它就起作用了：）

I found a solution! I just mount the key with my table Id and search Id (compId) and It's worked :)

scan = table.scan()
with table.batch_writer() as batch:
    for each in scan['Items']:
        batch.delete_item(
            Key={
                'uId': each['uId'],
                'compId': each['compId']
            }
        )
