Big Data Frameworks for Efficient Range Queries to Extract Interested Rectangular Sub Regions

چکیده
A satellite object can consist of more than one mosaic image. To extract any object from remote sensing satellite images, mosaic images need to be stitched. It is critical problem that which mosaics will be selected for image stitching among big mosaic dataset. In this paper, we propose two approaches to overcome mosaic selection problem by means of finding rectangular sub regions intersecting with range query. Former one is based on hybrid of Apache Hadoop and HBase and latter one is based on Apache Lucene. Their effectiveness has been compared in terms of response time under varying number of mosaics.

Indexing Continual Range Queries for Efficient Stream Processing
A large number of continual range queries could be issued against numerical data streams, such as stock prices, sensor readings, temperatures, and others. To efficiently process these long-running queries, only the potentially relevant queries should be evaluated against the data. We develop a virtual construct-based query indexing approach to efficiently identifying the range queries that matc...
متن کاملOptimal Partitioning for Efficient I/O in Spatial Databases
It is desirable to design partitioning techniques that minimize the I/O time incurred during query execution in spatial databases. In this paper, we explore optimal partitioning techniques for spatial data for diierent types of queries, and develop multi-disk allocation techniques that maximize the degree of I/O parallelism obtained during the retrieval. We show that hexagonal partitioning has ...

It is desirable to design partitioning techniques that minimize the I/O time incurred during query execution in spatial databases. In this paper, we explore optimal partitioning techniques for spatial data for diierent types of queries. In particular, we show that hexagonal partitioning has optimal I/O cost for circular queries compared to all possible non-overlapping partitioning techniques th...
متن کاملPrivacy and Security of Big Data in THE Cloud
Big data has been arising a growing interest in both scien- tific and industrial fields for its potential value. However, before employing big data technology into massive appli- cations, a basic but also principle topic should be investigated: security and privacy. One of the biggest concerns of big data is privacy. However, the study on big data privacy is still at a very early stage. Many or...
