Learning Hunk

By: Dmitry Anoshin, Sergey Sheypak

Overview of this book

Hunk is the big data analytics platform that lets you rapidly explore, analyse, and visualize data in Hadoop and NoSQL data stores. It provides a single, fluid user experience, designed to show you insights from your big data without the need for specialized skills, fixed schemas, or months of development. Hunk goes beyond typical data analysis methods and gives you the power to rapidly detect patterns and find anomalies across petabytes of raw data. This book focuses on exploring, analysing, and visualizing big data in Hadoop and NoSQL data stores with this powerful full-featured big data analytics platform. You will begin by learning the Hunk architecture and Hunk Virtual Index before moving on to how to easily analyze and visualize data using Splunk Search Language (SPL). Next you will meet Hunk Apps which can easy integrate with NoSQL data stores such as MongoDB or Sqqrl. You will also discover Hunk knowledge objects, build a semantic layer on top of Hadoop, and explore data using the friendly user-interface of Hunk Pivot. You will connect MongoDB and explore data in the data store. Finally, you will go through report acceleration techniques and analyze data in the AWS Cloud.

Big data performance issues


Despite the fact that, with modern technology, we can handle any big data issue, we still to have spend some time waiting for our questions to be answered. For example, we collect data and store it in Hadoop, then we deploy Hunk and configure a data provider, create a virtual index, and start to ask business questions by creating a query and running search commands. We should wait before the MapReduce job is finished. The following diagram illustrates this situation:

Moreover, if we want to ask the question over and over again by modifying the initial query, we will lose much time and money.

It would be superb if we could just run the search and immediately get the answer, as in the following diagram:

Yes, this is possible with Hunk, because it allows us to accelerate the report and get an answer to our business question very quickly. Let's learn how to do it.
