Infinispan and Vert.x coming to Codemotion Spain and Madrid JUG

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

Back from Portugal with goodies

The trip started in Coimbra where Sanne Grinovero and I discussed about Infinispan and OGM at the Portugal JUG. The interest was obvious from the amount of questions and the discussions that followed and ended up late in the night. A big thanks to Samuel Santos for organising this!

The trip then continued in Lisbon where we meet the CloudTM team for two good days of hacking and brainstorming.  The results are a set of awesome features the CloudTM is about to contribute to Infinispan, especially around transactions:

  • Total Order Broadcast (TOB) - is a transaction protocol for replicated caches built on atomic broadcast. It relies on JGroups'  SEQUENCER protocol for achieving total order. The benchmarks ran comparing it with the current 2PC based transaction protocol are rather promising and we hope to integrated it in our 5.2 release

  • Total Order Multicast (TOM) - is simplistically put TOB for distributed caches. This is the next in pipe after TOB to be integrated. Again, preliminary performance comparisons look rather promising

  • The  CloudTM also extended Infinispan’s transactions to support one-copy serializability (that’s a fancy name for SERIALIZABLE  transactions in replicated systems). The implementation is based on keeping multiple data version of data for each entry together with some housekeeping code. More on this to come!

Big thanks to CloudTM team for their effort and all the great ideas (and patches!!) they submitted to Infinispan! It was a great meeting with very good results and burning whiteboards (see below)!

Infinispan and OGM at PT.JUG

Sanne Grinovero and myself will talk about Infinispan and OGM at Portugal JUG in Coimbra on the April 18. This join talk covers an introduction to Infinispan and its main use cases followed by a presentation about NoSQL and Hibernate OGM. Thanks to Samuel Santos for inviting us and really looking forward to meet with the community!

Cheers,

Mircea

Thanks Alpes JUG. Next stop: Miracle Open World

Finally I was able to complete my trip to Grenoble to speak at Alpes JUG on the 29th of March about all things Infinispan, and I must say that I through fully enjoyed the experience. On arrival I was greeted by one of my JBossian colleagues, Chris Laprun, who lives in Grenoble.

After spending a few hours hanging around, we headed for the location of the Alpes JUG, where I met by Ludovic Poitou and other members of the JUG. The talk involved me speaking for 2 hours giving an overall view of Infinispan, while developing a simple application that would showcase Infinispan’s capabilities. As always with live demos, one or two things didn’t go fully according to plan, but overall the demo worked fine. For those who attended, remember that the demo code can be found here.

After the talk I had the chance to meet the attendants of the JUG where we discussed about caching, data grids, Hibernate 2nd level cache…​etc. Having had some pizza slices, Chris and I moved on to a pub in the old part of Grenoble where we’re able to watch my dear Athetic Bilbao crash Shalke 04 in the Europa League :).

Next day Chris and I met with another of the Alpes JUG leaders, called Emmanuel Hugonnet, with whom we had some lunch. I must say that I felt in love with the local cuisine having tried some local rather pinky sausage with cold lentils with mustard (what a great combo!). Here’s a pic:

It was a joy being invited to speak at Alpes JUG and I’d certainly recommend it to any Java speakers out there! I hope to come back some other time :).

So, what’s next? Next week I’m speaking at Miracle Open World 2012 in Billund’s Legoland park, where I’ll be joined by two other JBoss colleagues, Max Andersen and Thomas Heute. In this rather atypical conference, I’ll be speaking about measuring performance of in-memory data grids, and about building transactional, scalable Infinispan applications. I was already speaking at this conference last year, and together with GeeCON, this was one of my favourite conferences of 2011. Can’t wait for next week!

Cheers, Galder

Infinispan coming to Alpes JUG!

I was meant to speak in the Alpes JUG in Grenoble about Infinispan back in December, but due to a health issue, I was unable to attend. This session has now been rescheduled for this coming Thursday, 29th of March. As always, I will be speaking about all thing Infinispan, caching, data grids. Really looking forward to it! :)

Cheers, Galder

More JUG talks

Adrian Cole and I recently presented at a JUGs in Krakow and Dublin, on Infinispan and JClouds.

Krakow was great - and hot: 39 degree weather! (Don’t we just love global warming?) Anna Kolodziejczyk at Proidea (who also organises JDD) organised the event, which attracted an excited and interactive audience of about 40 people. Dublin, beautiful as always, was a polar opposite in terms of weather: a cloudy, windy and wet day, living up to its reputation. Luan O’Carroll of DUBJUG organised the event, at the plush Odessa Club. Again, an inquisitive audience of about 35 people attended, with a lot of questions on the future of data storage in clouds. Thomas Diesler of JBoss OSGi fame made a surprise guest appearance too.

In general, the talks have been very well received and have provoked thought and discussion. As requested by many, I will soon be recording a podcast of this talk and will make it available on this blog.

Apart from a JUG I hope to organise soon in London, the next time I speak about Infinispan publicly will be at JBoss World in September. Hope to see you there!

Cheers Manik

Berlin and Stuttgart say hello to Infinispan

image Last week I finally put together my presentation on cloud computing and Infinispan. To kick things off, I presented it at two JUG events in Germany.

Berlin’s Brandenburg JUG organised an event at the NewThinking Store in Berlin’s trendy Mitte district. Thanks to Tobias Hartwig and Ralph Bergmann for organising the event, which drew an audience of about 35 people. Cloud computing was the focus of the evening, and I started the event with my rather lengthy presentation on cloud computing and specific issues around persisting data in a cloud. The bulk of the presentation focused on Infinispan, what it provides as a data grid platform, and what’s on the roadmap. After a demo and a short break, Infinispan committer Adrian Cole then spoke about JClouds, demonstrating Infinispan’s use of JClouds to back cached state onto Amazon’s S3. You can read more about Adrian’s presentation on his blog.

Two days later, the Stuttgart JUG arranged for me to speak to their JBoss Special Interest Group on Infinispan. Thanks to Tobias Frech and Heiko Rupp for organising this event, which was held in one of Red Hat’s training rooms in Stuttgart. The presentation followed a similar pattern to what was presented in Berlin, to an audience of about 15 people.

In both cases, there was an overwhelming interest in Infinispan as a distributed storage engine. The JPA interface which is on our roadmap generated a lot of interest, as did the query API and to a lesser extent the asynchronous API - which could benefit from a better example in my presentation to demonstrate why this really is a powerful thing.

Overall, it is good to see that folks are interested in and are aware of the challenges involved in data storage on clouds, where traditional database usage is less relevant.

Many people have asked me for downloadable versions of my slides. Rest assured I will put them up - either as PDFs or better still, as a podcast - over the next 2 weeks.

Coming up, I will be in Krakow speaking at their JUG on Thursday the 23rd, and then in Dublin on Tuesday the 29th. Details of these two events are on the Infinispan Talks Calendar. Hope to see you there!

Cheers Manik

First experiences presenting Infinispan

Last week was one of the most exciting weeks for me since joining the Infinispan team because for the very first time, I was going to present Infinispan to the world :)

Firstly last Tuesday, I introduced Infinispan to Switzerlandhttp://www.jugs.ch/html/events/2009/infinispan.html['s Java User Group], where a crowd of around 20 people learned about the usability improvements introduced, the performance and memory consumption enhancements, and forthcoming new features. To finish the presentation, I showed the audience a demo of 3 distributed Infinispan instances connected to an Amazon S3 cache store via JClouds. I received some very positive feedback from the attendees who, in particular, were interested in finding out the differences between grid and cloud computing.

Two days later I went to Brussels to do the same presentation for Belgium’s JBoss User Group and the reaction was even better there! A lot of Spring developers attended the presentation who were very keen on integrating Infinispan in their own projects.

From here I’d like to thank all the people who attended these two sessions and in particular the organizers, Jakob Magun and Phillip Oser from Switzerland’s Java User Group and Joris De Winne from Belgium’s JBoss User Group.

Cheers, Galder

Upcoming JUG and JBUG talks on Infinispan

image I will be speaking at a number of JUGs around Europe this month. In addition, other core Infinispan devs will also be making JUG and conference appearances. I’ve put together a calendar of events which you can track, or add to your Google calendar to monitor.

This is a great chance for folks to learn about Infinispan, cloud and distributed computing, and where the project is headed. Hope to see you at one or more of these events!

Cheers Manik
