使用boto3将文件上传到S3时，file_upload()和put_object()有什么区别? [英] What is the Difference between file_upload() and put_object() when uploading files to S3 using boto3

问题描述

我正在使用boto3并尝试上传文件.如果有人解释 boto3 中file_upload()和put_object() s3存储桶方法的确切区别，这将很有帮助?

• 性能上有区别吗?
• 这些人之中有谁在后台处理分段上传功能吗?
• 两者的最佳用例是什么?

解决方案

upload_file方法由S3传输管理器处理，这意味着它会在必要时为您自动处理幕后分段上传.

put_object方法直接映射到低级S3 API请求.它不会为您处理分段上传.它将尝试在一个请求中发送整个正文.

I'm using boto3 and trying to upload files. It will be helpful if anyone will explain exact difference between file_upload() and put_object() s3 bucket methods in boto3 ?

• Is there any performance difference?
• Does anyone among these handles multipart upload feature in behind the scenes?
• What are the best use cases for both?

解决方案

The upload_file method is handled by the S3 Transfer Manager, this means that it will automatically handle multipart uploads behind the scenes for you, if necessary.

The put_object method maps directly to the low-level S3 API request. It does not handle multipart uploads for you. It will attempt to send the entire body in one request.
