The Hitchhiker’s Guide to Big Data

  • Zubair Nabi


By the time you get to the end of this paragraph, you will have processed 1,700 bytes of data. This number will grow to 500,000 bytes by the end of this book. Taking that as the average size of a book and multiplying it by the total number of books in the world (according to a Google estimate, there were 130 million books in the world in 20101) gives 65 TB. That is a staggering amount of data that would require 130 standard, off-the-shelf 500 GB hard drives to store. Now imagine you are a book publisher and you want to translate all of these books into multiple languages (for simplicity, let’s assume all these books are in English). You would like to translate each line as soon as it is written by the author—that is, you want to perform the translation in real time using a stream of lines rather than waiting for the book to be finished. The average number of characters or bytes per line is 80 (this also includes spaces). Let’s assume the author of each book can churn out 4 lines per minute (320 bytes per minute), and all the authors are writing concurrently and nonstop. Across the entire 130 million-book corpus, the figure is 41,600,000,000 bytes, or 41.6 GB per minute. This is well beyond the processing capabilities of a single machine and requires a multi-node cluster. Atop this cluster, you also need a real-time dataprocessing framework to run your translation application. Enter Spark Streaming. Appropriately, this book will teach you to architect and implement applications that can process data at scale and at line-rate.
