CloudTree: A Library to Extend Cloud Services for Trees
In this work, we propose a library that enables on a cloud the creation and
management of tree data structures from a cloud client. As a proof of concept,
we implement a new cloud service CloudTree. With CloudTree, users are able to
organize big data into tree data structures of their choice that are physically
stored in a cloud. We use caching, prefetching, and aggregation techniques in
the design and implementation of CloudTree to enhance performance. We have
implemented the services of Binary Search Trees (BST) and Prefix Trees as
current members in CloudTree and have benchmarked their performance using the
Amazon Cloud. The idea and techniques in the design and implementation of a BST
and prefix tree is generic and thus can also be used for other types of trees
such as B-tree, and other link-based data structures such as linked lists and
graphs. Preliminary experimental results show that CloudTree is useful and
efficient for various big data applications
A survey on big data indexing strategies
The operations of the Internet have led to a significant growth and accumulation of data known as Big Data.Individuals and organizations that utilize this data, had no idea, nor were they prepared for this data explosion.Hence, the available solutions cannot meet the needs of the growing heterogeneous data in terms of processing. This results in inefficient information retrieval or search query results.The design of indexing strategies that can support this need is required. A survey on various indexing strategies and how they are utilized for solving Big Data management issues can serve as a guide for choosing the strategy best suited for a problem, and can also serve as a base for the design of more efficient indexing strategies.The aim of the study is to explore the characteristics of the indexing strategies used in Big Data manageability by covering some of the weaknesses and strengths of B-tree, R-tree, to name but a few. This paper covers some popular indexing strategies used for Big Data management. It exposes the potentials of each by carefully exploring their properties in ways that are related to problem solving
