    Abstract

    Users of MapReduce often run into performance problems when they scale up
    their workloads. Many of the problems they encounter can be overcome by
    applying techniques learned from over three decades of research on parallel
    DBMSs. However, translating these techniques to a MapReduce implementation such
    as Hadoop presents unique challenges that can lead to new design choices. This
    paper describes how column-oriented storage techniques can be incorporated in
    Hadoop in a way that preserves its popular programming APIs.

    Abstract

    Database management systems (DBMSs) have largely ignored the task of managing
    the energy consumed during query processing. Both economical and environmental
    factors now require that DBMSs pay close attention to energy consumption. In
    this paper we approach this issue by considering energy consumption as a
    first-class performance goal for query processing in a DBMS. We present two
    concrete techniques that can be used by a DBMS to directly manage the energy
    consumption. Both techniques trade energy consumption for performance.
