Titan Provides Real-Time Big Graph Data

From the post:

Titan is an Apache 2 licensed, distributed graph database capable of supporting tens of thousands of concurrent users reading and writing to a single massive-scale graph. In order to substantiate the aforementioned statement, this post presents empirical results of Titan backing a simulated social networking site undergoing transactional loads estimated at 50,000–100,000 concurrent users. These users are interacting with 40 m1.small Amazon EC2 servers which are transacting with a 6 machine Amazon EC2 cc1.4xl Titan/Cassandra cluster.

The presentation to follow discusses the simulation’s social graph structure, the types of processes executed on that structure, and the various runtime analyses of those processes under normal and peak load. The presentation concludes with a discussion of the Amazon EC2 cluster architecture used and the associated costs of running that architecture in a production environment. In short summary, Titan performs well under substantial load with a relatively inexpensive cluster and as such, is capable of backing online services requiring real-time Big Graph Data.

BTW, Titan is reported to emerge as 0.1 (from 0.1 alpha) later this (2012) summer.
