In this talk, I'll describe the SimSQL system, which is a platform for writing and executing statistical codes over large data sets, particularly for machine learning applications. Codes that run on SimSQL can be written in a very high-level, declarative language called Buds. A Buds program looks a lot like a mathematical specification of an algorithm, and statistical codes written... Read More

Got petabytes to query? Give us a few. Fetch trillions of rows? Done, what's next? Entire data center down? Still fast and strongly consistent. The Mesa system must serve detailed ads data for reporting, internal audits, analysis, billing, forecasting and more. Meanwhile, Advertisers use the same data to gain fine-grained insights into their campaigns' performance. Because users include complex enterprise... Read More

Abstract: The preferred treatment for kidney failure is a transplant; however, demand for donor kidneys far outstrips supply.  Kidney exchange, an innovation where willing but incompatible patient-donor pairs can exchange organs---via barter cycles and altruist-initiated chains---provides a life-saving alternative.  Typically, fielded exchanges act myopically, considering only the current pool of pairs when planning the cycles and chains.  Yet kidney exchange...

With the rise of large-scale, Web-based applications, users are increasingly adopting a new class of document-oriented database management systems (DBMSs) that allow for rapid prototyping while also achieving scalable performance. Like for other distributed storage systems, replication is an important consideration for document DBMSs in order to guarantee availability. Replication can be between failure-independent nodes in the same data center... Read More

Abstract: This talk addresses the problem in Web page ranking of effectively combining link and content information with efficiency high enough to be applicable to real-world search engines. Unlike previous surfer models, our approach is based on the viewpoint of a Web page author. Based on this viewpoint, we formulate the concept of contribution score, which indicates the amount to...

Web applications (web mail, web stores, social networks, etc) keep massive amounts of data that must be readily available to users. The storage system underlying these applications has evolved dramatically over the past 25 years, from file systems, to SQL database systems, to a large variety of NOSQL systems. In this talk, we contemplate this fascinating history and present a... Read More
