Distributed Sparse Spatial Selection Indexes
Verónica Gil-Costa, Mauricio Marı́n · 2008
Searching for similar objects in metric-space databases can be efficiently solved by using index data structures. A number of alternative sequential indexes have been proposed in the literature. This paper proposes the parallelization of a recent pivot-based index data structure which can efficiently accommodate on-line updates and reduces the number of object-to-object comparisons during searches. We present algorithms for index construction and query processing.
