Our First Athens MongoDB Meetup!

  • Jan 16, 2013 · 6:30 PM
  • This location is shown only to members


18:30 Registration and welcome coffee (15')

18:45 MongoDB basics by Thanasis Efthymiou (45')

Thanasis Efthymiou "wanted to work with computers" since the childhood days he couldn't afford (and never got) an 8088. He enjoyed four years developing telecom SW in Siemens, and another two years of QA in banking and mobile marketing applications. Since 2009 he is a Service Delivery Manager in Upstream and Persado, launching more promos than he can remember around the globe. His every day struggle is pursuing operational excellence and that's why he prefers automating tasks using various programming languages. When his queries won't run, he prefers cycling.

19:30 Replication & High Availability by Alexandros Giamas (30')

Alex Giamas is an avid enthusiast of non relational technologies since 2005. He has studies in NTUA, Carnegie Mellon and Stanford university in the fields of Computer Science and engineering. He has worked in Verizon and Yahoo! and for the past 3 years has led the design and implementation of the Reporting Services for the MCS platform at Upstream Systems. His interests lie from MongoDB to every mammal in the Hadoop ecosystem to NewSQL technologies.

20:00 Break (10')

20:10 Sharding by Christos Soulios (30')

Christos Soulios is a team leader and software architect at Persado. He has been working as a software engineer and architect for more than 10 years designing, implementing and rolling out software for major players of the banking and telecommunications sectors in Greece. He has studied Computer Science and holds a postgraduate degree in High Performance Computing. His main focus is highly scalable transactional systems, while enjoys learning new languages and programming paradigms.

    It was extremely interesting for people that did not have any familiarity with mongodb. Good explanation of the basic concepts, but also detailed enough for people already using this type of database giving them important insights of this technology.

    Looking forward fot the next meeting, maybe a deeper view to the already referenced concepts would be a great idea.

    Great Start!

    Very Very good start. especially for those who did't have a clue about mongodb. Looking forward for the next meetup.

  • Papapetrou P.

    Any chance that we get the presentation slides?

    January 17, 2013

  • Vassilis T. is the admin app mentioned during the meetup. Good first meetup by the way. For the next one it would be nice to also have some dev session... I guess there are not only admins in the group, right?

    It was great, thank you.

  • Andreas G.

    It was very interesting, didn't know about MongoDB insights and the huge difference with RDBMS. It's a pleasure to hear the community finally started questioning stereotypes, at least for those who dare and not afraid failures while evolving!

    Keep it up!

    although did not manage to get there from the beginning, got to see 1/2 of the 1st presentation and the other two. Good material, good introduction for mongo and replica sets plus a nice intro on sharding and what it is for

    Guys (or should I say fellow geeks :)), have a look on It's a small one page note taking web app so you may find it useful today. It is built on MongoDB with Mongoid on Rails3. For the front-end we are using Backbone.js. It's hosted on Heroku with MongoHQ. I'd be glad to share my experience although it's still in early development. Is anyone else in the group working on production applications that use MongoDB?

    January 16, 2013

  • Dimi B.

    Unfortunately I won't be able to join due to unforeseen workload combined with the distance to Athens. So there's one vacancy for a fellow hacker in the waiting list.

    Wish you guys good luck with this first meetup and esp. to my friend Alex who introduced me to MongoDB several years ago :-)
    Hope to see you in the next event!

    January 16, 2013

  • Dimitris D.

    Any chance you can accommodate all the people on the waiting list?

    January 15, 2013

    • Thanasis E.

      Hi Dimitri, as I said in my previous comment, 50 is the maximum seating capacity, not to mention that coffee and snacks have been arranged accordingly due to our very,very limited budget - needless to say, if Upstream and 10gen wouldn't be kind enough to sponsor us, we wouldn't even be able to offer water! :-P So, if you don't mind standing and fighting for a cup of coffee, then it's really hard for me to "forbid" anyone to join us.

      January 15, 2013

  • Elias B.

    Any chances to increase capacity?

    January 15, 2013

    • Thanasis E.

      Unfortunately not...! :-( The meeting room is not that big (and that's the biggest we could use), and I'm afraid that 50 is the maximum seating capacity. It's really great having 95 members already, and maybe we should rethink our housing requirements for next time. I really wish everybody could join us, but without a sponsor and/or funding for a larger place, our options are limited. Actually, the only option would be to utilize's premium membership features and charge all our members who RSVP Yes with 2 or 5 or 10 or I don't know how many Euros. I guess you realize that that didn't even cross my mind and, given the circumstances, that's the last thing we should do.

  • Papapetrou P.

    Hi guys, It's really awesome to see that the first MUG meetup is organized. IMHO, having a meetup in the middle of the week is not very convenient, so I'd suggest that future meet-ups will take place during weekends...

    January 4, 2013

    • Thanasis E.

      I'm afraid I will have to agree with Stavros. A lot of people are also married with children, and pantofla is highly incoming if you're willing to abandon family plans for any kind of conference... :-) Yet, we may consider it, provided Patroklos' suggestion finds common ground.

      January 4, 2013

    • Papapetrou P.

      You almost convinced me guys :) The only counter-argument is that during the week working hours is a problem especially when you need to come from the other side of the city with public transportation :)
