What the research is:  RAMP-TAO is a new protocol that improves the developer experience on TAO, Facebook’s online social graph store, by providing stronger transactional guarantees. It is the first protocol to provide transactional semantics over an eventually consistent massive-scale data store while still preserving the system’s overall reliability and performance. RAMP-TAO enables an intuitive [...] Read More... The post RAMP-TAO: Layering atomic transactions on Facebook’s online graph store appeared first on Facebook Engineering. http://dlvr.it/S5ts30

We are excited to announce our participation in the Apricot subsea cable system, together with leading regional and global partners. When completed, the project (which is still subject to regulatory approvals) will deliver much-needed internet capacity, redundancy, and reliability to expand connections in the Asia-Pacific region. The 12,000-kilometer-long cable will connect Japan, Taiwan, Guam, the [...] Read More...

Facebook engineers have built and open-sourced an Open Compute Time Appliance, an important component of the modern timing infrastructure. To make this possible, we came up with the Time Card — a PCI Express (PCIe) card that can turn almost any commodity server into a time appliance. With the help of the OCP community, we [...] Read More... The post Open-sourcing a more precise time appliance appeared first on Facebook Engineering. http://dlvr.it/S5Rd13

What the research is:  A first-of-its-kind study detailing our backbone management strategy to ensure high service performance throughout the COVID-19 pandemic. The pandemic moved most social interactions online and caused an unprecedented stress test on our global network infrastructure with tens of data center regions. At this scale, failures such as fiber cuts, router misconfigurations, [...] Read More...

ZippyDB is the largest strongly consistent, geographically distributed key-value store at Facebook. Since we first deployed ZippyDB in 2012, this key-value store has expanded rapidly, and today, ZippyDB serves a number of use cases, ranging from metadata for a distributed filesystem, counting events for both internal and external purposes, to product data that’s used for [...] Read More...

We are releasing Winterfell, our implementation of a STARK prover/verifier to Crates.io  Winterfell is an easy to use open source implementation of STARKs for security and privacy applications. One potential application for Winterfell’s zero-knowledge proofs is blockchain privacy and scalability.  “Any sufficiently advanced technology is indistinguishable from magic.” —Clarke’s Third Law What if the average [...] Read More...
