Presentations

Cassandra Workshop

9:00 AM MDT

What do you do when your data is not only big, but also needs to be fast? Apache Cassandra is a scalable, fault-tolerant database that has found its way into more than 25% of the Fortune 100 and continues to enjoy significant adoption in the marketplace.

In this workshop, we’ll explore Cassandra’s internals, its flexible data model, its SQL-like query language, some deployment scenarios, and some common language bindings. You’ll leave ready to begin exploring Cassandra on your own.

Building Java Applications with Cassandra

8:30 AM MDT

So you’re a JVM developer, you understand Cassandra’s architecture, and you’re on your way to knowing its data model well enough to build descriptive data models that perform well. What you need now is to know the Java Driver.

What seems like an inconsequential library that proxies your application’s queries to your Cassandra cluster is actually a sophisticated piece of code that solves a lot of problems for you that early Cassandra developers had to code by hand. Come to this session to see features you might be missing and examples of how to use the Java driver in real applications.

Cassandra and Spark

10:30 AM MDT

Apache Cassandra is a leading open-source distributed database capable of amazing feats of scale, but its data model requires a bit of planning for it to perform well. Of course, the nature of ad-hoc data exploration and analysis requires that we be able to ask questions we hadn’t planned on asking—and get an answer fast. Enter Apache Spark.

Spark is a distributed computation framework optimized to work in-memory, and heavily influenced by concepts from functional programming languages. It’s exactly what a Cassandra cluster needs to deliver real-time, ad-hoc querying of operational data at scale.

In this talk, we’ll explore Spark and see how it works together with Cassandra to deliver a powerful open-source big data analytic solution.

Building and Testing with Gradle

Building and Testing with Gradle

by Tim Berglund and Matthew McCullough

Build and test software written in Java and many other languages with Gradle, the open source project automation tool that’s getting a lot of attention. This concise introduction provides numerous code examples to help you explore Gradle, both as a build tool and as a complete solution for automating the compilation, test, and release process of simple and enterprise-level applications.

Discover how Gradle improves on the best ideas of Ant, Maven, and other build tools, with standards for developers who want them and lots of flexibility for those who prefer less structure.

  • Use Gradle with Groovy, Clojure, Scala, and languages beyond the JVM, such as Flex and C
  • Get started building a simple Java program using Gradle's command line tooling and a small build script
  • Learn how to configure and construct tasks, Gradle's fundamental unit of build activity
  • Take advantage of Gradle's integration with Ant
  • Use Gradle to integrate with or transition from Maven, and to build software more cleanly
  • Perform application unit and integration tests using JUnit, TestNG, Spock, and Geb
