BENCHMARKING BIG SPATIAL DATA PROCESSING FRAMEWORKS
Journal Title: Современные информационные технологии и ИТ-образование - Year 2018, Vol 14, Issue 1
Abstract
Today, the processing of large amounts of spatial data in distributed systems plays a crucial role in many areas of our life. Large data are often unstructured, and special algorithms are required for its processing. One of the methods for analyzing large data is a spatial analysis. The source of large data in this case is often the geographical information system. In this article, a benchmark is considered to evaluate the frameworks that work with such data. Also, the evaluation results of three frameworks according to developed benchmark are presented: GeoSpark, STARK, SpecialSpark. In the course of this paper, we considered a benchmark of two types: macrobenchmark and microbenchmark. In the paper, testing of topological predicates on various topological data is also considered. The comparison was made using the DE-9IM model. This model is used to determine the types of topological relationships, such as intersection, equality, etc. The main problem of comparing the data frameworks was that not all of them support the operations of the selected model, which influenced the formation of scenarios for the microbenchmark and macrobenchmark, since it was impossible to compare all the DE-9IM items.
