PosDB: A Distributed Column-Store Engine
Ch. 7. P. 88–94.
Chernishev G., Smirnov K., Galaktionov V., Klyuchikov E., Grigorev V.
In this paper we present a novel disk-based distributed column-store, describe its architecture and discuss a number of technical solutions. Our system is essentially a query engine which was written completely from scratch. It is aimed for shared-nothing environments and supports different forms of parallel query processing.
Query processing in PosDB is organized according to the classic Volcano pull-based model which is adapted for the column-store case. Currently, we support late materialization only, and therefore employ a join index data structure to represent positional information. In our system query plan can consist of both positional and value operators. PosDB has about a dozen of core operators among which several variants of selections and joins, aggregation. We also have several operators that ensure intra-query parallelism and operators for network interoperability. In its current state the system is fully capable of processing the Star Schema Benchmark in a local and distributed environment.

Information on the emotional characteristics of words is widely used in contemporary re-search on emotional stimulus processing, as well as in linguistic and psycho-linguistic studies. Since the parameters of the emotional valence of words constitute subjective linguistic charac-teristics and therefore require dedicated empirical studies, some researchers have focused on developing databases containing information on the ...

Array DBMSs operate on big N-d arrays. Cellular automata (CA) work on a discrete lattice of cells, essentially on N-d arrays. CA facilitate decision support as they realistically simulate complex phenomena including road traffic, fire spread, and urban growth. Array DBMSs can bring numerous benefits to the CA domain via a ``database approach'': powerful parallelization, ...

Geospatial array DBMSs operate on georeferenced N-d arrays. They provide storage engines, query parsers, and processing capabilities as their core functionality. Traditionally, those have been too heavy for a Web browser to support. Hence, Web Applications, mostly Geographic Information Systems (GISs), run array management on their server back-ends that return small portions of the results ...

The discovery of gamma-ray burst (GRB) host galaxy back in 1997 brought confirmation of GRBs cosmological origin. Nowadays investigation of the host galaxies often is the only way to estimate the cosmological redshift of GRB sources. The morphology of host galaxies gives clues to the nature of the environment, where the GRBs were born, and ...

Gamma-ray bursts (GRBs) are the most energetic and yet the most
mysterious events in the Universe, which are observed in all ranges of electromagnetic
spectrum from radio-bandwidth up to very high energy of about TeV
energies. Moreover, recently GRBs accompanying gravitational waves produced
in binary neutron starmerging were discovered. Despite on theGRBis initially registering
by space-born gamma-ray omnidirectional detectors or ...

В любой науке интересно рассмотреть ситуацию, когда инструмент исследования сам становится его объектом. Очень схематично говоря, когда линейкой измеряют линейку или весами взвешивают весы. Усложним: когда проверяют, подчиняется ли учебник физики законам, написанным в нём (почти всегда), или психолог - правилам преподаваемой психологии (редко). В наукометрии такой подход особенно логичен, он ей внутренне присущ. Классик, ...
