By Sherif Sakr

This ebook presents readers the “big photograph” and a finished survey of the area of massive facts processing platforms. For the previous decade, the Hadoop framework has ruled the realm of massive information processing, but lately academia and have began to realize its barriers in different program domain names and massive info processing eventualities corresponding to the large-scale processing of established info, graph information and streaming info. hence, it truly is now progressively being changed by way of a set of engines which are devoted to particular verticals (e.g. dependent information, graph info, and streaming data). The e-book explores this new wave of platforms, which it refers to as enormous info 2.0 processing systems.

After bankruptcy 1 offers the final history of the massive information phenomena, bankruptcy 2 offers an outline of varied general-purpose gigantic info processing structures that permit their clients to strengthen numerous great information processing jobs for various program domain names. In flip, bankruptcy three examines quite a few platforms which were brought to aid the SQL style on best of the Hadoop infrastructure and supply competing and scalable functionality within the processing of large-scale dependent facts. bankruptcy four discusses a number of platforms which have been designed to take on the matter of large-scale graph processing, whereas the main target of bankruptcy five is on numerous structures which were designed to supply scalable options for processing massive facts streams, and on different units of structures which were brought to aid the improvement of knowledge pipelines among quite a few varieties of significant facts processing jobs and platforms. finally, bankruptcy 6 stocks conclusions and an outlook on destiny study challenges.

Overall, the publication deals a useful reference advisor for college kids, researchers and pros within the area of massive info processing platforms. additional, its finished content material will expectantly inspire readers to pursue extra examine at the subject.

Sample text

In principle, the Hadoop framework consists of two main components: the Hadoop Distributed File System (HDFS) and the MapReduce programming model. In particular, HDFS provides the basis for distributed Big Data storage which distributes the data files into data blocks and stores such data in different nodes of the underlying computing cluster in order to enable effective parallel data processing. 2 Enhancements of the MapReduce Framework In practice, the basic implementation of MapReduce is very useful for handling data processing and data loading in a heterogeneous system with many different storage systems.

3 illustrates the architecture of the Impala system that consists of three main components: The Impala daemon (impalad) that accepts queries from client processes and orchestrates their execution across the cluster. The Impala daemon that operates in the first role by managing query execution is considered the coordinator for that query. However, all Impala daemons are symmetric. That means they may all operate in all roles which helps with fault tolerance and with load balancing. The Statestore daemon (statestored) is a metadata publish-subscribe component that disseminates clusterwide metadata to all Impala processes.

28 2 General-Purpose Big Data Processing Systems only jobs on Hadoop and uses HDFS for data input and output. Apache Hama10 is another BSP-based implementation project designed to run on top of the Hadoop infrastructure, like Giraph. However, it focuses on general BSP computations and not only on graph processing. For example, it includes algorithms for matrix inversion and linear algebra. Machine learning algorithms represent another type of applications which are iterative in nature. Apache Mahout 11 project has been designed for building scalable machine learning libraries on top of the Hadoop framework.
