Challenges to Adopting Stronger Consistency at Scale

Workshop on Hot Topics in Operating Systems

There have been many recent advances in distributed systems that provide stronger semantics for geo-replicated data stores like those underlying Facebook. At Facebook we are excited by these lines of research, but fundamental and operational challenges currently make it infeasible to incorporate these advances into deployed systems. This paper describes some of these challenges with the hope that future advances will address them.

The Lifecycles of Apps in a Social Ecosystem

Proc. WWW'15

Apps are emerging as an important form of on-line content, and they combine aspects of Web usage in interesting ways — they exhibit a rich temporal structure of user adoption and long-term engagement, and they exist in a broader social ecosystem that helps drive these patterns of adoption and engagement. It has been difficult, however, to study apps in their natural setting since this requires a simultaneous analysis of a large set of popular apps and the underlying social network they inhabit.

Wormhole: Reliable Pub-Sub to Support Geo-replicated Internet Services

12th USENIX Symposium on Networked Systems Design and Implementation

Wormhole is a publish-subscribe (pub-sub) system developed for use within Facebook’s geographically replicated datacenters. It is used to reliably replicate changes among several Facebook services including TAO, Graph Search and Memcache. This paper describes the design and implementation of Wormhole as well as the operational challenges of scaling the system to support the multiple data storage systems deployed at Facebook.

The Diffusion of Support in an Online Social Movement: Evidence from the Adoption of Equal-Sign Profile Pictures

Proc. CSCW'15

In March of 2013, 3 million Facebook users changed their profile picture to one of an equals sign to express support of same-sex marriage. We demonstrate that this action shows complex diffusion characteristics congruent with threshold models, with most users observing several of their friends changing their profile picture before taking the action themselves.

Moving Fast with Software Verification

NASA Formal Method Symposium

For organisations like Facebook, high quality software is important. However, the pace of change and increasing complexity of modern code makes it difficult to produce error free software. Available tools are often lacking in helping programmers develop more reliable and secure applications.
