Experience
A File Downloader Module for a Web Crawler
https://github.com/akabeera/file-downloaderA Python module that can be used on its own or integrated into a web crawler for downloading media from the internet. The file downloader supports various protocols such as HTTPS, FTP, and SFTP and even has an interface where consumers can plug in their custom modules.
The file downloader is very robust in that it's able to support huge files (50GB+ range) without timing out, it's ready to automatically restart a download in the event of losing internet connection, and it allows you to control the memory usage of each download.
It is also very configurable. You can specify the number of files to download in parallel, by size, and to break each file while downloading. You can also specify the max timeout for connecting to a server as well as waiting for server activity during a file download.
