问题描述

是否可以在Amazon AWS的DynamoDB中向现有表添加新列？

Is there a way to add a new column to existing table in DynamoDB in Amazon's AWS?

Google没有帮助，

Google didn't help,

http://docs.aws.amazon.com/cli/latest/reference/dynamodb/update-table .html？highlight = update％20table 没有与添加新列有关的任何信息。

UpdateTable Query in http://docs.aws.amazon.com/cli/latest/reference/dynamodb/update-table.html?highlight=update%20table doesn't have any information related to adding a new column.

推荐答案

DynamoDB不需要架构定义，因此没有列之类的东西。您只需添加具有新属性的新项目即可。

DynamoDB does not require schema definition, and so there is no such thing as a "column". You can just add a new item with a new attribute.
