Another way to define Spark is as a VERY fast in-memory, data-processing framework – like lightning fast. 100x faster than Hadoop fast. As the volume and velocity of data collected from web and mobile apps rapidly increases, it’s critical that the speed of data processing and analysis stay at least a step ahead in order to support today’s Big Data applications and end user expectations. Spark offers the competitive advantage of high velocity analytics by way of stream processing large volumes of data, versus what has been traditionally a more heavily “batch-oriented” approach to data processing as seen with Hadoop. Spark also provides a more inclusive framework allowing for multiple analytics processing options including: fast interactive queries, streaming analytics, graph anal

Java 8 vs Scala: a Feature Comparison

This article explores some of Java 8’s new features, using both Java’s proposed syntax and Scala. We cover lambda expressions, higher-order functions, parallel collections and virtual extension methods aka traits. Besides this, we will provide insights into the new paradigms integrated in Java 8, such as functional programming.
