I am pleased to invite you to our third Munich Open Hadoop User Group Meeting!

Like always we are looking forward to see everyone again and are welcoming new attendees to join our group. We are enthusiast about all things related to scalable, distributed storage system. We are not limiting us to a particular system but appreciate anyone who would like to share about their experiences.

When: Thursday May 6th, 2010 at 6pm (open end)
Where: eCircle AG, Nymphenburger Straße 86, 80636 München ["Bruckmann" Building, "U1 Mailinger Str", map (in German) and look for the signs]

Thanks again to Bob Schulze from eCircle for providing the infrastructure.

We have a talk scheduled by Stefan Seelmann who is a member of the project committee for the Apache Directory project. This is followed by an open discussion.

Please RSVP at Xing and Yahoo's Upcoming.

Looking forward to seeing you there!

Cheers,
Lars

Let me take a minute to wrap up my FOSDEM 2010 experience. I was part of the NoSQL DevRoom organized by @stevenn from Outerthought, who I had the pleasure to visit before a few months back as an HBase Ambassador.

First things first, the NoSQL DevRoom was just an absolute success and I had a blast attending it. I also made sure to not walk around and see other talks outside the NoSQL track while there were many and plenty good ones. I did so deliberately to see the other projects and what they have to offer. I thought it was great, a good vibe was felt throughout the whole day as the audience got a whirlwind tour through the NoSQL landscape. The room was full to the brim for most presentations and some folks had to miss out as we could not have had more enter. This did prove the great interest in this fairly new kind of technology. Exciting!

The focus of my talk was about the history I have with HBase starting with it in late 2007. At this point I would like to take to the opportunity to thank Michael Stack, the lead of HBase, as he has helped me many times back then to sort out the problems I ran into. I would also like to say that if you start with HBase today you will not have these problems as HBase has matured tremendously since then. It is an overall stable product and can solve scalability issues you may face with regular RDBMS's today - and that with great ease.

So the talk I gave did not really sell all the features nor did it explain everything fully. I felt this could be left to the reader to look up on the project's website (or here on my blog) and hence I focused on my use case only. First up, here are the slides.


My Life with HBase - FOSDEM 2010 NoSQL -

After my talk and throughout the rest of the day I also had great conversations with the attendees who had many and great questions.

Having listened to the other talks though I felt I probably could have done a better job selling HBase to the audience. I could have reported about use-cases in well known companies, gave better performance numbers and so on. I have learned a lesson and am making sure I will be doing a better job next time around. I guess this is also another facet of what this is about, i.e. learning to achieve a higher level of professionalism.

But as I said above, my intend was to report about my life with HBase. I am grateful though that it was accepted as that and please let me cite Todd Hoff (see Hot Scalability Links for February 12, 2010) who put it in such nice words:

"The hardscabble tale of HBase's growth from infancy to maturity. A very good introduction and overview of HBase."

Thank you!

Finally here is the video of the talk:



I am looking forward to more NoSQL events in Europe in the near future and will attempt to represent HBase once more (including those adjustments I mentioned above). My hope is that we as Europeans are able to adopt these new technologies and stay abreast with the rest of the world. We sure have smart people to do so.

At the end of last year we had a first meeting in Munich to allow everyone interested in all things Hadoop and related technologies to gather, get to know each other and exchange their knowledge, experiences and information. We would like to invite for the second Munich OpenHUG Meeting and hope to see you all again and meet even more new enthusiasts there. We would also be thrilled if those attending would be willing to share their story so that we can learn about other projects and how people are using the exciting NoSQL related technologies. No pressure though, come along and simply listen if you prefer, we welcome anyone and everybody!

When: Thursday February 25, 2010 at 5:30pm open end
Where: eCircle AG, Nymphenburger Straße 86, 80636 München ["Bruckmann" Building, "U1 Mailinger Str", map (in German) and look for the signs]

Thanks again to Bob Schulze from eCircle to provide the location and projector. So far we have a talk scheduled by Christoph Rupp about HamsterDB. We are still looking for volunteers who would like to present on any related topic (please contact me)! Otherwise we will have an open discussion about whatever is brought up by the attendees.

Last but not least there will be something to drink and we will get pizzas in. Since we do not know how many of you will come we simply stay at the events location and continue our chats over food.

Looking forward to seeing you there!

Please RSVP at Upcoming or Xing.

First Munich OpenHUG Meeting

We are trying to gauge the interest in a south Germany Hadoop User Group Meeting. After seeing quite a big interest in the Berlin meetings a few of us got together and decided to test the waters for another meeting at the other end of the country. We are therefore happy to announce the first Munich OpenHUG Meeting.

When: Thursday December 17, 2009 at 5:30pm open end
Where: eCircle AG, Nymphenburger Straße 86, 80636 München ("Bruckmann" Building, "U1 Mailinger Str", map in German and look for the signs)

Thanks to Bob Schulze from eCircle to provide the location, projector and also giving a first presentation on how eCircle is planning to use the Hadoop stack.

We also have Dave Butlerdi giving an overview of his usage of Hadoop.
Finally I will give a state of affairs of the HBase project. What is it, what does it do and how am I using it (since early 2008).

We are also open for everyone who wants to talk about anything related to these new technologies often combined under the rather new term "NoSQL". Take the opportunity to talk about what you are working on and find like minded people to bounce ideas off. This is also why we chose the title OpenHUG for the meeting. While we mostly work with Hadoop and its subprojects we also like to learn about related projects and technologies.

Last but not least there will be something to drink and we will get pizzas in. Since we do not know how many of you will come on such short notice we simply stay at Bob's place and continue or chats over food.

As this is a first meeting in Munich on this topic we called it in a day after the Berlin meeting. Given there is interest we will in the future settle on dates that fit nicely between the Berlin dates so that we have no overlap and you can attend both meetings.
