“…Another space partitioning strategy is based on KDB-tree, a balanced binary tree, which has been used in load balancing of spatial databases for fast querying. It is worth mentioning that the locality of data and load balancing are important to speedup queries performance [29].…”

“…Contrary to previous methods that are all based on centralized systems, in [52] we pro posed the first MapReduce algorithm to effectively process the GKNN query in a parallel and distributed environment. Utilizing ideas and elements from previous work (query defini tion and heuristics [60], processing without indexes and PS heuristics [65,67], repartitioning data [24,27]), in this paper we present an algorithm consisting of seven phases, local or…”

“…The algorithm in [53] utilized ideas and elements from previous works, namely query definition and heuristics [60], processing without indexes and PS heuristics [65,67], reparti tioning of data [24,27]. A new high performance point/cell filtering method was introduced as well as several other calculation improvements and output data minimization techniques, which greatly improved total algorithm performance.…”
