重命名AWS S3存储桶中的文件夹的成本 [英] Cost of renaming a folder in AWS S3 bucket

问题描述

我想重命名S3存储桶中的文件夹，我知道重命名将运行一个PUT请求，每1000个请求的成本为1美分.

I want to rename a folder in S3 bucket, I understand that rename will run a PUT request which costs 1 cent per 1000 request.

但是，PUT请求被定义为COPY，并且还涉及GET

However, the PUT request is defined as a COPY and involves with also a GET

我的问题是，当我们在S3存储桶中重命名文件夹时，是否涉及将所有子文件夹和文件复制到具有我想要的名称(费用超过1个PUT请求)的新文件夹中，或者仅仅是1 PUT请求更改名称而不触摸文件夹内的所有项目.

My question is, when we rename a folder in S3 bucket, does it involve copying all sub-folders and files to a new folder with the name I want (which costs more than 1 PUT request), or it just simply 1 PUT request to change the name without touching all the items within the folder.

推荐答案

如果您错过了它……S3中没有文件夹.

In case you've missed it... there are no folders in S3.

对象/pics/funny/cat.jpg是不是的文件，而在另一个名为pics的文件夹中的funny文件夹中的cat.jpg文件.

The object /pics/funny/cat.jpg is not a file called cat.jpg inside a folder called funny inside another folder called pics.

实际上，它是一个具有18个字符的名称的文件:pics/funny/cat.jpg.控制台中显示的层次结构在很大程度上是为了方便人使用，并且在控制台中创建新文件夹的能力也是一种幻想.

In fact, it is a file with an 18-character name: pics/funny/cat.jpg. The hierarchy shown in the console is largely for human convenience, and the ability to create new folders in the console is an illusion, also.

因此，是的，重命名文件夹"实际上意味着在文件夹"中为每个对象创建一个新副本，并更改​​对象名称以使其看起来像在路径中一样.

So, yes, renaming a "folder" actually means making a new copy of each object in the "folder," with a change to the object names to look like their are in the path.

这可以通过PUT/COPY请求(每1000个$ 0.005，取决于区域)来完成，然后再执行旧对象的DELETE请求(免费).没有相应的GET请求，因为PUT/COPY是S3内部的原子操作，因此可以避免实际下载和重新上传数据.

This can be done with a PUT/COPY request ($0.005 per 1000 depending on the region) followed by a DELETE request of the old object (free). There is no corresponding GET request, because PUT/COPY is an atomic operation inside S3, so actually downloading and re-uploading the data is avoided.
