Changes To VODs On Twitch
Aug 06 2014 · Engineering, Tech
Our goal at Twitch is straightforward: deliver the highest quality video. This includes the ability to watch video on demand (VOD) on all of our platforms, not just the website.
In order to create a system that supports live and VOD across the globe and on multiple platforms, we need to make significant changes to the way we’re currently storing video. Today, we’d like to discuss what these changes are, why they’re necessary, and how they benefit the entire Twitch community now and in the future.

Looking at Viewership Data
We found that the vast majority of past broadcast views happen within the first two weeks after they’re created. On the days following, viewership reduces exponentially.
We also discovered that 80% of our storage capacity is filled with past broadcasts that are never watched. That’s multiple petabytes for video that no one has ever viewed.
Highlights, on the other hand, have much more value and longevity. Over their lifetime, highlights get 9x as many views as past broadcasts.
[...]
As for existing past broadcasts, beginning three weeks from today, we will begin removing them from Twitch servers. If you would like to keep your past broadcasts, we encourage you to begin exporting or making highlights of your best moments so that they’re saved for posterity.

appears to do some of them- Is there any irregularities? Differences between highlights and past broadcasts?
Storage Issues
- How to decide which are important? 10+ views again? Do a discovery crawl first?
- Tahoe-LAFS? Grab all the videos into temp storage?
- Compress all the unwatched videos into postage stamp sized videos?
How can I help?
