NoSQL Paper: The Trinity Graph Engine

Even if my first post about the Micosoft research graph database Trinity is back from March last year, I haven’t heard much about it since. Based on my tip, Klint Finley published an interesting speculation about Trinity, Dryad, Probase, and Bing. Since then though, Microsoft moved away from using Dryad to Hadoop and I’m still not sure about the status of the Trinity project. But I have found a paper about the Trinity graph engine authored by Bin Shao, Haixun Wang, Yatao Li. You can read it or download it after the break.

We introduce Trinity, a memory-based distributed database and computation platform that supports online query processing and offline analytics on graphs. Trinity leverages graph access patterns in online and offline computation to optimize the use of main memory and communication in order to deliver the best performance. With Trinity, we can perform efficient graph analytics on web-scale, billion-node graphs using dozens of commodity machines, while existing platforms such as MapReduce and Pregel require hundreds of machines. In this paper, we analyze several typical and important graph applications, including search in a so- cial network, calculating Pagerank on a web graph, and sub-graph matching on web-scale graphs without using index, to demonstrate the strength of Trinity.
