Infinispan has been on tour!!

 I - Katia Aresti - had the chance to present 3 talks in 3 different conferences and countries during the last month:

Breizh Camp 2019 the 22th March, Rennes (France)

Greach Conf 2019, 29th March, Madrid (Spain)

Voxxed Days Milano 2019, 13th April, Milan (Italy)

A few days after Devoxx France, I headed for Great Indian Developer Summit in Bangalore where I spoke about handling streaming data on top of a Kubernetes platform. This was a very similar talk to the one I gave at JFokus but with some important changes. Together with Clement we created a small RxJava 2 façade for Infinispan. When combined with Vert.x RxJava 2 API, we could finally have an idiomatic way of handling streaming data asynchronously and coordinating events purely using RxJava 2 APIs. This is crucial for working with streaming data in an efficient way. On top of that, I made some changes to push the binary data used by the demo outside of the deployment.

Unfortunately Murphy struck during the presentation and I was unable to run the live coding demo. A problem with Docker size image during preparation combined with a cleanup I ran before the talk meant some of the images had to be re-downloaded. The wireless internet connection at the conference nor the mobile connection were good enough for me to recover it. Once back in the hotel where I had a stable connection I was able to record a screencast of the steps I would have followed during the Great Indian Developer Summit talk. You can find this screencast below:

The code from the demo can be found here. The live coding steps I followed are defined here. Finally the slides can be found here:

Finally, for something slightly different, back in March I joined Ray Tsang for a talk at Voxxed Days Zurich. This was a really fun talk to be part of! We combined past stories of my time at JBoss support with Ray’s Kubernetes troubleshooting experience to create an engaging talk :). You can find the video below:

The week after Sebastian Łaskawiec and I travelled to Red Hat Summit as part of the work we did to integrate Red Hat Data Grid (Infinispan product version) into the Scavenger Hunt game presented on the keynote of the last day. Both Sebastian and I have been working on a blog series which will be published very soon.

Ever since we started the Infinispan project, I simply don’t recall a time busier than the current one! As usual we’re working on new features and supporting our community and enterprise users, but on top of that we’re working on a big scale demo that we hope you are going to like it!

All of that has been happening with at the same time juggling one of the busiest periods in Infinispan evangelisation that I can remember! Here’s what I have been up to past month and a half:

On 18th of March I gave a brand new presentation at Javaland where I explored the Java RPC framework landscape. Since 2010, Infinispan has offered a binary remote, client/server API for interacting with the data. As more clients have been developed, we’ve been noticing that we’re spending more time that’d we’d like implementing features across different clients. In this talk I looked at existing Java RPC frameworks from the point of view of Infinispan’s remote API requirements. If we were to implement our binary protocol again, which option would fit best? The spectrum can be very vast so I limited myself to some know options (HTTP 1.1 REST), some options we have expertise on (Netty), some upcoming players (gRPC) and some lesser known but very powerful players (Aeron). The talk was not recorded but the slides can be found here:

Javaland was a very enjoyable conference set in a theme park near Cologne. The sessions were a mix in German and English. Although my German is not very good, I was able to follow some of the sessions.

After Javaland, I turned my attention to Devoxx France which was held in Paris mid-April. I had a couple of sessions at Devoxx France. The first was a streaming data analysis 3 hour university talk delivered along with Clement Escoffier from the Vert.x team. We already delivered this session at JFokus earlier this year, but at Devoxx France it was recorded so you’ll soon to be able to watch it! In the mean time, slides can be found below:

On top of that, Ray Tsang from Google joined Clement and I to deliver a 3 hour streaming data hands-on lab at Devoxx France. This was the same workshop we delivered in Devoxx Belgium and Codemotion Madrid in 2017. The big difference was that instead of having the users run it locally on their laptops within a virtual machine, they could run OpenShift and all the components inside of Google Cloud Platform. The users had a better experience as a result of not having to deal with a virtual machine :). I’d like to say special thanks to Ray for the Google Cloud Platform test accounts and the support during the workshop.

Finally, many thanks to all attendees that came to the sessions, and to the organisers/sponsors for creating two outstanding events!

In the next blog post I’ll be talking about Great Indian Developer Summit and Voxxed Days Zurich. Stay tuned! :)

Cheers, Galder

We’re now back from JFokus and we’d like to thank organizers, attendees, volunteers and sponsors for making JFokus a very enjoyable experience! :)

From an Infinispan perspective, we started the week with a Streaming Data deep-dive session presented together with Clement Escoffier. This was a 3h long session, so there was plenty to go through but we managed to do it on time. The final demo did not fully work, but this is something we will improving it in the near future. Slides can be found in [1]

Next day I had a talk on streaming data analysis on top of Kubernetes where I went through some of the topics explained in the deep dive. This was mostly a live coding session showing how to work with streaming data on top OpenShift/Kubernetes which run on Google Cloud. This session was recorded. I’ll keep an eye for when the video becomes available to share it here. The code from this session can be found here, slides here and the live coding instructions here.

The rest of the conference was a blast, with many networking opportunities. During this networking I started working on an RxJava2 API facade for Infinispan remote API, which would make it easier to fit with other reactive toolkits out there, such as Vert.x :). More news on this soon

Cheers, Galder

The Infinispan team is on the move again! After Katia’s trip to Snowcamp, it’s my turn to head  to JFokus, Sweden’s largest developer conference.

For JFokus we’ve morphed the streaming data workshop we delivered last year at Devoxx Belgium and Codemotion Madrid into a 3 hour long deep dive tutorial. This will be delivered Monday 5th February at 13:30 local time.

On top of that, I’ll be delivering a talk on streaming data analysis with Kubernetes where Infinispan will be featured. If you’re interested make sure you come on Tuesday, 6th February at 14:00 local time.

So, if you’re coming to JFokus and you’re interesting in data grids, streaming data or similar topics, make sure you attend our talks.

Cheers, Galder

This week, I’m recovering from the Snowcamp 2018 conference in Grenoble. I had an amazing time there, where I could hang-out with people from the french community, discussing tech, coding, non-blocking APIs, lifestyle and diversity!

My talk was on Thursday at 15:00. It was very exciting for me because I was live-coding in front of so many people for the first time! I got very valuable feedback from attendees and speakers to improve my content, live-coding skills and encouragements to submit this talk to other user groups and conferences this year.

This presentation focuses on the work we have been doing to provide a new API available in Infinispan 9.2 (final release coming very very soon!!!): Clustered Locks. These locks are distributed and non blocking, allowing us to synchronise protected code between different Infinispan nodes across a cluster.

It’s a 45 minutes talk, so I’m not presenting the API just from the user point of view; instead I go deep into the actual Clustered Locks internals. We have built this first implementation on top of existing Infinispan’s APIs, which proves that they can be used to do much more than just speeding your applications and caching!

The first user of these locks is the Vert.x-Infinispan Cluster Manager. Before going into the implementation details, I show how to create a cluster of Vert.x applications using Infinispan and a simple example of when and how to use a Vert.x Lock. Underneath Vert.x Locks, the next release of the cluster manager will be using the Clustered Locks API. I’m preparing a longer article on this matter, so stay tuned! Meanwhile, enjoy the presentation slides!

This week, the 25th of January, I will be presenting a talk about Clustered Locks at the Snowcamp 2018 conference in Grenoble (France). During the live-coding talk, I will share the design and code I’ve been working on to create this first version of the clustered locks. These locks will be used by the Vert.x Cluster Manager, but they can be useful to any Infinispan user since version 9.2 (final release coming very soon!!). If you are planning to use this API, we would love to hear from you to give us some feedback and keep us posted on your use case!

If you are attending the conference, fell free to reach me to discuss about Infinispan+Vert.x, locks, Multimap, cute names or any other topic that you care about!

See you!

It’s been a very busy year from an Infinispan evangelisation perspective, so before the year ends, we wanted to round up the conferences and user groups that featured Infinispan related talks. This is a good opportunity to catch up on what we’ve been showing in our Infinispan outings:

We’ve just come back from our trip to Spain and first of all, we’d like to thank everyone who attended our talks and workshops at Madrid Java User Group and Codemotion Madrid as well organisers and sponsors who made it possible!

We had a very hectic schedule, which started with a Red Hat double bill for Madrid JUG. Thomas Segismont started the evening with Vert.x talk and Galder followed up with a talk on how to do data analytics using Infinispan-based data grids.

In the data analytics talk, Galder focused on how to use distributed Java Streams to do analytics and also showed how to use Infinispan Spark connector when Java Streams are not enough. The distributed Java Streams demo he ran can be found here. The most relevant files of that demo are:

Galder also demonstrated how to use Infinispan Spark connector by showing the Twitter example. The slides from this talk (in Spanish) can be found here:

Next day on Friday, Galder gave a talk at Codemotion Madrid on working with streaming data with Infinispan, Vert.x and OpenShift. For the first time he was running it all on top of Google Cloud, so he could finally free up my laptop from running the demos and take advantage of the power of a cloud provider!

The demo can be found here where you can also find instructions on how to run it on top of Google Cloud. If you want to follow the same steps he followed during the talk, live coding instructions are here. The slides from this talk (in Spanish) can be found here:

Finally on Saturday we delivered the Streaming Data workshop at Codemotion Madrid. Once again, basing our workshop on top of Virtual Box still caused us some issues, but people managed to get through it. We have some plans for next year to avoid the need of Virtual Box, stay tuned!

We have added more detailed instructions on how to run the workshop in your office or at home, so if you’re interested in going through it, make sure you check these steps and let us know how they work for you:

This trip to Madrid wraps up a very intense year in terms of promoting Infinispan! Next month we’ll be doing a recap of the talks, videos…​etc so that you can catch up with them in case you missed any of them :)

Katia & Galder Un saludo!

I’m happy to announce that Infinispan and Eclipse Vert.x team members are in Madrid (Spain) this week!

The 23th of November, Galder (Infinispan) and Thomas (Vert.x) will be presenting at Madrid Java User Group two talks about Infinispan and Ver.x. From my side, I’ve been invited to give a talk about programming career path to Computer Science and Engineering students in the Universidad San Pablo CEU. 

The following days, 24th and 25th of November, Codemotion Spain will take place in Madrid. Codemotion is the biggest developer centric conference in Spain. More than 1.500 people will be attending this year. The conference does not focus on any particular technical stack. You can learn about mobile, web, front-end, back-end, devops and there are some inspirational tracks too during the two days of the conference.

On Friday, Galder will be presenting a talk about Streaming and BigData architecture. Thomas will be presenting "Better performance on server side with HTTP/2" and I will join a debate around Enterprise Culture, where I will give my insights about RedHat’s Culture. On Saturday we will run our Streaming Data Workshop: a hands on lab that showcases a simplified streaming architecture built on top of Infinispan and Vert.x and running on OpenShift. If you cannot attend any of these events, you can always do the workshop at your self peace.

We hope to see you in Madrid, or anywhere else in 2018!!

Cheers, Katia
