使用 boto3 将驻留在 s3 子文件夹中的特定文件下载到我的本地计算机中

Question

I have a file resides in a s3 bucket subfolder. Bucket name "testbucket", folder name-"folder1". File name:"sample.csv". I want to download that into my local machine: "/Users/sameer/desktop/folder1".

What is the most efficient way to do download that if the file size is more than 3gb

Answer 1

Use the AWS CLI

aws s3 cp s3://testbucket/folder1/sample.csv /Users/sameer/desktop/folder1

if you must boto3:

import boto3

s3_client = boto3.client('s3')

s3_client.download_file('testbucket', 'folder1/sample.csv', '/Users/sameer/desktop/folder1/sample.csv')
