Big Data Concept

  Introduction In the era of big data, datasets grow exponentially in volume, velocity, and variety, necessitating specialized frameworks for efficient processing. Big data processing frameworks enable scalable handling of massive datasets across distributed systems, surpassing the capabilities of traditional databases. This chapter explores batch and real-time processing paradigms, key frameworks like Apache Hadoop, Apache Spark, Apache Kafka, and Apache Flink, and the role of Extract, Transform, Load (ETL) processes in data pipelines. The purpose is to teach scalable data handling, covering theoretical foundations, practical implementations, and architectures. Through code snippets, diagrams, and case studies, readers will learn to select and apply these frameworks for real-world applications, addressing challenges like fault tolerance, data locality, and parallelism. Overview: Batch vs. Real-Time Processing Big data processing is divided into batch and real-time (stream) proc...

In April of 2009, IBM made available a revolutionary product named IBM InfoSphere Streams (Streams). Streams is a product architected specifically to help clients continuously analyze massive volumes of streaming data at extreme speeds to improve business insight and decision making. Based on ground-breaking work from an IBM Research team working with the U.S. Government, Streams is one of the first products designed specifically for the new business, informational, and analytical needs of the Smarter Planet Era. Overview of Streams As the amount of data available to enterprises and other organizations dramatically increases, more and more companies are looking to turn this data into actionable information and intelligence in real time. Addressing these requirements requires applications that are able to analyze potentially enormous volumes and varieties of continuous data streams to provide decision makers with critical information almost instantaneously. Streams p...
