以编程方式发现AWS DynamoDB表的所有属性吗？ [英] Discovering all attributes of a AWS DynamoDB table programmatically?

问题描述

我知道可以通过全表扫描&检查所有记录是否存在属性。有没有那么痛苦的方法？

I know that this can be done with a full table scan & inspecting all records for the presence of attributes. Is there a less painful way ?

推荐答案

不，没有。这是DynamoDB的权衡之一。

No, there isn't. This is one of the trade-offs of DynamoDB.

如果有办法做到这一点，则存储具有新属性的新项目将不得不更新其他内容。 ，记住了表中存在的所有属性。

If there was a way to do this, then storing a new item with a new attribute would have to update something else, somewhere else, that remembered all of the attributes that were present in the table.
