Invited Talk: Storage and Index Support for Data Intensive Web Applications

In this talk, a system named as DisGR, for Distributed Graph Repository, that is designed and developed for supporting Chinese Web related research, is introduced. The system is designed based on a graph data model, TGM (Tagged Graph Model), which is designed for representing Web data, especially forum and BBS data. DisGR supports the query language TGM-L that aims at analytical tasks for TGM data. For high-scalability and availability purpose, DisGR is designed for clusters with shared nothing architecture. DisGR has several important features such as column-based storage, descriptive language support, and flexible user-defined function support. DisGR could be distinguished from other database systems with similar purpose by the following three perspectives. First, catalog is maintained by a set of servers connected via a DHT overlay. Second, signatures with different granularities are used for data distribution and query optimization. Last but not the least, update is supported via time stamps and regular reorganization.
