The authors report on the second annual ACM SIGMOD programming contest, which consisted of building an efficient distributed query engine on top of an in-memory index. This paper is co-authored by the organizers of the competition (Cl?ment Genzmer, Pierre Senellart) and the students who built the two leading implementations (Volker Hudlet, Hyunjung Park, Daniel Schall). For the second year in a row, a programming contest was organized in parallel with the ACM SIGMOD 2010 conference. Undergraduate and graduate student teams from over the world were invited to compete to develop an efficient distributed query engine over relational data.
