How to use asyncio to download files on s3 bucket

由 ぐ巨炮叔叔 提交于 2020-05-16 12:57:48
问题 I'm using the following code to download all my files in a s3 bucket: def main(bucket_name, destination_dir): bucket = boto3.resource('s3').Bucket(bucket_name) for obj in bucket.objects.all(): if obj.key.endswith('/'): continue destination = '%s/%s' % (bucket_name, obj.key) if not os.path.exists(destination): os.makedirs(os.path.dirname(destination), exist_ok=True) bucket.download_file(obj.key, destination) I would like to know how to make this asynchronous, if possible. Thank u in advance.

Show RDS Metrics for multiple instances

由 柔情痞子 提交于 2020-05-14 20:22:44
问题 I would like to pull RDS Cloudwatch Metrics using Boto for multiple databases at once. So far I have only been able to get metrics for only one instance at a time using an approach like this: botoRDS = boto.connect_cloudwatch(aws_access_key_id=Key, aws_secret_access_key=OtherKey) instanceStats = botoRDS.get_metric_statistics(period=60, start_time=self.startTime, end_time=self.endTime, namespace="AWS/RDS", metric_name='CPUUtilization', statistics=["Average"], dimensions={'DBInstanceIdentifier'

How to implement a priority queue using SQS(Amazon simple queue service)

由 给你一囗甜甜゛ 提交于 2020-05-14 17:18:38
问题 I have a situation when a msg fails and I would like to replay that msg with the highest priority using python boto package so he will be taken first. If I'm not wrong SQS queue does not support priority queue, so I would like to implement something simple. Important note : when a msg fails I no longer have the message object, I only persist the receipt_handle so I can delete the message(if there was more than x retries) / change timeout visibility in order to push him back to queue. Thanks!

How to find size of a folder inside an S3 bucket?

由 ε祈祈猫儿з 提交于 2020-05-13 04:39:14
问题 I am using boto3 module in python to interact with S3 and currently I'm able to get the size of every individual key in an S3 bucket. But my motive is to find the space storage of only the top level folders (every folder is a different project) and we need to charge per project for the space used. I'm able to get the names of the top level folders but not getting any details about the size of the folders in the below implementation. The following is my implementation to get the top level

Python常用的22个包，你都学费了吗？

由 孤人 提交于 2020-04-28 19:55:09
全球各地的程序员都是怎样使用 Python？ 我们从最常用的 Python 包入手，去解答上述这个问题。最初，我列出过去一年在 PyPI 上下载次数最多的 Python 包。接下来，深入研究其用途、它们之间的关系和它们备受欢迎的原因。 1、Urllib3 下载次数：8.93 亿 Urllib3 是一个 Python 的 HTTP 客户端，它拥有 Python 标准库中缺少的许多功能： 线程安全 连接池 客户端 SSL/TLS 验证 使用分段编码上传文件 用来重试请求和处理 HTTP 重定向的助手 支持 gzip 和 deflate 编码 HTTP 和 SOCKS 的代理支持 不要被名字所误导， Urllib3 并不是 urllib2 的后继者，而后者是 Python 核心的一部分。如果你想使用尽可能多的 Python 核心功能，或者你能安装什么东西是受限，那么请查看 urlllib.request。 对最终用户来说，我强烈建议使用 requests 包（参阅列表中的 #6）。这个包之所以会排名第一，是因为有差不多 1200 个包依赖 urllib3，其中许多包在这个列表中的排名也很高。 2、Six 下载次数：7.32 亿 six 是一个是 Python 2 和 3 的兼容性库。这个项目旨在支持可同时运行在 Python 2 和 3 上的代码库。 它提供了许多可简化 Python 2

Ubuntu18.04 从头开始编译 Android Native WebRTC

由 ぃ、小莉子 提交于 2020-03-19 19:59:12
3 月，跳不动了？>>> 本文详细记录Mac下使用PD虚拟机安装ubuntu18.4桌面版，编译Android Native WebRTC的过程。 注意如果仅仅是使用WebRTC没必要手动编译源码，直接用官方提供的预编译包即可： The easiest way to get started is using the official prebuilt libraries available at JCenter. These libraries are compiled from the tip-of-tree and are meant for development purposes only. On Android Studio 3 add to your dependencies: implementation 'org.webrtc:google-webrtc:1.0.+' On Android Studio 2 add to your dependencies: compile 'org.webrtc:google-webrtc:1.0.+' The version of the library is 1.0.. The hash of the commit can be found in the .pom-file. The third party licenses

问题 I am packaging my ML solution which includes keras and tensorflow using PyInstaller. The exe builts just fine but when I execute the exe it gives an ModuleNotFoundError for boto . The solution works just fine if I run it using the script. All the dependencies were installed. Here is my spec file: block_cipher = None a = Analysis(['main.py'], pathex=['.'], binaries=[], datas=[('data\\*.tsv', 'data')], hiddenimports=['sklearn.neighbors.typedefs','sklearn.neighbors.quad_tree','sklearn.tree.
