6:10-7:00: Transforming your Code to Java 8

The new facilities in Java 8 is about the change the way we write code. Our code will become more expressive and concise. But, exactly how?

In this presentation we will take several common Java code examples, discuss the core idea expressed in code, and transform that code to use the facilities in Java 8. Watch and interact as you see Java code go through a weight loss program right in front of your eyes.

7:00-7:10: Break

7:10-8:00: Programming with Streams in Java 8

We all have heard about lambda expressions in Java 8. The real unsung hero of Java 8 are the Streams.

In this presentation we will take an example driven approach to explore streams, their core capabilities form the application development point of view, and how to explore these capabilities for improve performance and efficiency.

6:20-7:50: MongoDB + Vert.x = Red Hot goodness by Steven Pousty

Vert.x is a polyglot async ready application server that runs on the JVM. It comes with a built in Event Bus and uses JSON for message passing. That use of JSON makes for some very interesting integration pieces with MongoDB. In this talk I will start by introducing some of the basic concepts of Vert.x, such as Verticles, EventBus, and a ton of built in features. From there I will demonstrate how easy it is to run a WebSocket enabled application that provides live tracking map of airplane flights. The code will be a mix of JavaScript, Java, and Python to flex some polyglotness. Then with a few lines of code I will demonstrate how easy it is to push the same feed of data straight into a spatially enabled MongoDB instance. Given the way both plaforms are such a close fit, I will show how easy it is to also add a REST query service right on top of the API. Don’t let all the Node.JS hipsters have all the fun – come see the exciting possibilities for JavaScript or Java application with Vert.x and MongoDB.

About Steven Pousty

Steve is a Dad, Son, Partner, and PaaS Dust Spreader (aka developer evangelist) with OpenShift. He goes around and shows off all the great work the OpenShift engineers do.

This is my laptop. There are many like it, but this one is mine.
It is not however the environment in which my application will run once it is deployed in production.
We will look at how Ansible can be used to consistently build an environment that is ready to receive a web application, whether it is running on a local Vagrant box, an EC2 instance or a Digital Ocean droplet.

6:20-7:50: Benchmarking Solr Performance at Scale – Timothy Potter

Organizations continue to adopt Solr because of its ability to scale to meet even the most demanding workflows. Recently, LucidWorks has been leading the effort to identify, measure, and expand the limits of Solr. As part of this effort, we’ve learned a few things along the way that should prove useful for any organization wanting to scale Solr. Attendees will come away with a better understanding of how sharding and replication impact performance. Also, no benchmark is useful without being repeatable; Tim will also cover how to perform similar tests using the Solr-Scale-Toolkit in Amazon EC2.​

About Timothy Potter

Timothy Potter is a Lucene/Solr committer and Sr. Engineer at LucidWorks where he focuses on hardening SolrCloud for searching big data and recently co-authored Solr in Action. Tim has over 16 years experience building innovative software solutions that encompass a wide range of technologies and business sectors. Early in his career, Tim was a member of the JBI expert group and was a Senior Software Engineer for the WebLogic Platform at BEA Systems, where he was the chief inventor of several US Patents that helped revolutionize J2EE based application integration. Tim built his first Lucene-based search application in 2007 and has worked extensively with Lucene / Solr ever since. Prior to joining LucidWorks, Tim was the lead architect for a large-scale Solr-based search application for social media content. Mr. Potter has BS in Mathematics and BA in Economics with honors (summa cum laude) from the University of Colorado.​
