DevNation Live Blog: Building Reactive Applications with Node.js and Red Hat JBoss Data Grid
Last Tuesday I gave a talk at DevNation 2016 on building Reactive Applications with Node.js and Red Hat JBoss Data Grid. The slides for it will be uploaded to the DevNation site shortly, but for those who want to play around with the application demoed in the talk, you can find the code and instructions in this repository.
The Red Hat Developers blog posted a review of the talk in this address: http://developers.redhat.com/blog/2016/06/29/devnation-live-blog-building-reactive-applications-with-node-js-and-red-hat-jboss-data-grid/

DevNation Live Blog: Building Reactive Applications with Node.js and Red Hat JBoss Data Grid
Posted by Rob Terzi on June 29, 2016
At DevNation, Red Hat’s Galder Zamarreño gave a talk with a live demo, Building reactive applications with Node.js and Red Hat JBoss Data Grid. The demo consisted of building an event-based three tier web application using JBoss Data Grid (JDG) as the data layer, an event manager running on Node.js, and a web client. Recently, support for Node.js clients was added to JDG, opening up the performance of a horizontally scalable in-memory data grid, to reactive web and mobile applications.
JDG is capable of processing and storing real-time streams of data, while maintaining very fast response times. It does this by using the memory available from a dynamically scalable grid of machines. Galder described JDG as a four-in-one package capable of being:
-
a distributed cache.
-
a high performance NoSQL primary data store.
-
an event-driven data store, particularly for real time event processing.
-
a big data and Internet of Things (IoT) data store.
The three-tiered web app in the demo consisted of:
-
A web client written in Elm, which is a functional language that compiles to JavaScript. It is statically typed, which the presenter feels leads to well architected code. Elm competes with platforms such as React and Angular. Any of those other platforms could be used, but Galder chose Elm for the live demo, particularly given the useful error messages the compiler generates as a virtue of using a statically typed language.
-
An event manager running on Node.js using Express.js.
-
JBoss Data Grid as the data store. Three nodes were used, running on the same laptop. Each element was guaranteed to be stored in two nodes, providing redundancy for fail over.
Node.js based applications have become very popular. Many use JavaScript on all three tiers, including NoSQL data stores. However, most of those data stores can’t match the scalability and response times of JDG. Traditionally, developers have needed to use Java to take advantage of JBoss Data Grid. The new fully asynchronous Node.js interface to JBoss Data Grid should enable developers to build some truly interesting next-generation reactive applications.
You can download JBoss Data Grid from developers.redhat.com. If you’d like to get involved, join the open source community at infinispan.org.

DevNation 2016: Galder Zamarreño on “Building reactive applications with Node.js and Red Hat JBoss Data Grid”
Earlier this month I did an interview with the DevNation 2016 organizers to talk about my talk on forthcoming talk on building reactive applications with Node.js and JBoss Data Grid, the Infinispan version for which Red Hat provides professional support, certified integration, patches…etc.
The talk will be happen next Tuesday, 28th June at 3:30pm PDT, so if you’re in DevNation and want to find out more about Infinispan and our new Node.js Javascript client, make sure you join us then!
Building reactive applications with Node.js and Red Hat JBoss Data Grid
JBoss Data Grid is a distributed in-memory key/value data store from Red Hat, which can be used for caching, temporary and permanent storage. Although Java developers were its primary audience initially, the team has been expanding its appeal to C++, C# and even Javascript developers.
The latest JBoss Data Grid release includes a fully asynchronous Node.js client for interacting with JBoss Data Grid servers and my talk at DevNation is focused on how Javascript developers can make the most of the client to cache or store their data.
The talk has been designed around a web application that promotes JBoss Data Grid talks in forthcoming conferences, user groups… etc. The application will contain a Node.js component whose job will be to interact with the backend JBoss Data Grid servers to store and retrieve data, as well as receiving events when new information has been added to the backend. Through the live coding of this application, the audience will get an understanding of how to interact with the newly released Node.js JBoss Data Grid client, and after the talk they’ll have access to the code to be able to try it themselves.
Tuesday 3:30 p.m. to 4:30 p.m. Room 133
About the presenter:
This will be my first time speaking at DevNation and I’m really excited about it because it brings together speaks and attendees not only from the Java/JVM space, but from other important developer communities such as Javascript.
Although I started as a Java developer, over the past decade I’ve become more and more interested in other programming languages, in particular functional programming languages such as Scala and Javascript, which I’ve been able to apply directly at my job.
These days I’m hugely interested by the purely functional ones such as Haskell, Elm or Purescript because the lack of mutability makes their solutions both elegant and easier to reason about. I’m also keeping a close eye as well on the Erlang ecosystem, e.g. Elixir, because I feel that the predictable latency offered by the Erlang VM is something that it’s not so easy to achieve in Java Virtual Machine.
I think learning other programming languages is one of the best things a developer can do, because it opens your mind to different points of view, different ways to solve problems, and widens the solution space.

Infinispan related presentations on DevConf.cz 2016
DevConf.cz (Developer Conference) is a free annual conference for all Linux and JBoss Community Developers, Admins and Linux users organized by Red Hat Czech Republic in cooperation with the Fedora and JBoss communities. See more details on DevConf’s homepage.
Since it’s JBoss related conference, Infinispan cannot be missing there! We had two Infinispan related presentantions. First of them was presented by Jiří Holuša focusing on new features in Infinispan 8. The presentation also covers very gentle introduction to Infinispan in general.
The second one, named "From Big Data towards Fast Data", was given by Vojtěch Juránek and talked about latest trends in Big Data world. The presentation goes through the introduction about Big Data, mentions the problems with it and comes up with the term Fast Data. Some approaches are presented, how to solve this Fast Data phenomenon, ending up with new Infinispan Spark connector as one of the possible solutions.
Please, see the links below.

Infinispan at Snowcamp 2016
Last week the first ever Snowcamp was held in Grenoble where I presented about "Distributed Data Processing with Infinispan and Java Streams".
The conference was very enjoyable with multiple tracks focused on Big Data, web technologies (with a big emphasis on Javascript), devops, and software development. Emmanuel, Mickael and the rest of the team did an awesome job at organising the conference in record time with very good attendance numbers :)
The talk went well and fortunately the demo gods were with me that day :). The code of the demo can be found in this Github repository. The slides will be available soon.
Of the presentations I attended, I was particularly impressed with the Apache Zeppelin talk that Saad Ansari presented where he demonstrated how to do interactive data analysis on top of Apache Spark, very cool!
It was a pleasure being selected to talk at Snowcamp and hope that next year I can speak there too!
Cheers, Galder

SnowCamp and Voxxed Days Bucharest, here I come!!
I’ll be presenting about Infinispan’s in a couple of conferences over the next few months:
First up is SnowCamp 2016, a conference taking place in Grenoble from 21st to 23rd January. The talk I’m presenting is titled "Distributed Data Processing with Infinispan and Java Streams". Java 8 has made data processing easier than ever and with the help of Infinispan, that data processing can easily be done in a distributed manner. This talk is focused on showing how to use Java Streams to do distributed data processing with Infinispan, and how this approach compares with other data processing APIs Infinispan exposes.
Next, on the 11th of March I’ll be in Bucharest to speak at Voxxed Days Bucharest where I’ll again be talking about Distributed Data Processing with Infinispan and Java Streams.
So, if you’re in Grenoble or Bucharest, make sure you come to SnowCamp or Voxxed Days Bucharest to learn about Infinispan!! :)
Cheers, Galder
