My Technical Blog: OpenStack Swift Amar's Blog Perspective


I have graduated from UW-Madison in December 2012 and joined as a Research Staff Member at NEC Laboratories America. When I was in school, my advisor was Prof. Jignesh Patel. I received my BS from Beijing University of Technology (BJUT) with the thesis advisor Dr. Junzhong Ji.

ICDE Source Code Download:

This is the source code of ICDE 2010 and SIGMOD 2008 (Y.Tian and J.Patel). Please direct all comments and bug reports to me, nzhang at

Data Crawler Download:

The crawlers of DBLP and IMDB datasets are now available. Please read the NOTE file in the code package. Also, parsing XML data file needs DTD file, however, DTD file may not always come with the source data (Citeseer only provides the XML data, but not DTD file). Fortunately, I found this DTD generator very useful when DTD file is not available.


My current research focuses on high-performance SQL engine on key-value store, multi-tenant DBMS and cloud storage.
