如何批量更新DDB中现有的items?

【以下的问题经过翻译处理】 你好，
DDB中有BatchGetItem()和BatchWriteItem()函数, 但是无法批量更新现有Items,
参考链接:
- https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB/DocumentClient.html#batchWrite-property
- https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html#batchWriteItem-property
- 注意：BatchWriteItem 无法更新项目。要更新项目，请使用 UpdateItem 操作。
是否有函数或者其他方法可以批量更新现有Items?

【以下的回答经过翻译处理】 你可以通过DynamoDB PartiQL来完成批量更新操作, BatchExecuteStatement API 操作最多允许读取 25个项目或写入25 个项目.
参考文档: https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_BatchExecuteStatement.html
