Using Spark SQL for basic data analysis

Interactively, processing and visualizing large data is challenging as the queries can take a long time to execute and the visual interface cannot accommodate as many pixels as data points. Spark supports in-memory computations and a high degree of parallelism to achieve interactivity with large distributed data. In addition, Spark is capable of handling petabytes of data and provides a set of versatile programming interfaces and libraries. These include SQL, Scala, Python, Java and R APIs, and libraries for distributed statistics and machine learning.

For data that fits into a single computer, there are many good tools available, such as R, MATLAB, and others. However, if the data does not fit into a single machine, or if it is very complicated to get the data to that machine, or if a single computer cannot easily process the data, then...
