Angle-based space partitioning for efficient parallel skyline computation
Akrivi Vlachou, Christos Doulkeridis, Yannis Kotidis · 2008
Recently, skyline queries have attracted much attention in the database research community. Space partitioning techniques, such as recursive division of the data space, have been used for skyline query processing in centralized, parallel and distributed settings. Unfortunately, such grid-based partitioning is not suitable in the case of a parallel skyline query, where allpartitions are examined at the same time, since many data partitions do not contribute to the overall skyline set, resulting in a lot of redundant processing.
