Dropbox Photos - Building abstractions on top of the file system
"Dropbox is moving away from a file-folder centric view of user data to a content-centric view. This talk will focus on a couple of the abstractions we've built on top of the file system - metadata indexing and virtual collections - that enable rich interactions with the content type in question. Photos is the first content vertical to take this approach - abstracting away the file-folder view from the user but, underneath the covers, staying constantly in sync with it. We'll go into some of the technical details of the general-purpose infrastructure we've built in this regard and the product experiences they enable."
