A Distributed Query Processing Engine
Wireless sensor networks (WSNs) are formed of tiny, highly energy-constrained sensor nodes that are equipped with wireless transceivers. They may be mobile and are usually deployed in large numbers in unfamiliar environments. The nodes communicate with one another by autonomously creating ad-hoc networks which are subsequently used to gather sensor data. WSNs also process the data within the ne...
متن کاملVerdictDB: Universalizing Approximate Query Processing
Despite 25 years of research in academia, approximate query processing (AQP) has had little industrial adoption. One of the major causes for this slow adoption is the reluctance of traditional vendors to make radical changes to their legacy codebases, and the preoccupation of newer vendors (e.g., SQL-on-Hadoop products) with implementing standard features. On the other hand, the few AQP engines...

متن کاملXG: A Grid-Enabled Query Processing Engine
In [12] we introduce a novel architecture for data processing, based on a functional fusion between a data and a computation layer. In this demo we show how this architecture is leveraged to offer significant speedups for data processing jobs such as data analysis and mining over large data sets. One novel contribution of our solution is its data-driven approach. The computation infrastructure ...
متن کاملSketch Techniques for Approximate Query Processing
Sketch techniques have undergone extensive development within the past few years. They are especially appropriate for the data streaming scenario, in which large quantities of data flow by and the the sketch summary must continually be updated quickly and compactly. Sketches, as presented here, are designed so that the update caused by each new piece of data is largely independent of the curren...
