We're excited to announce the very first Cassandra Meetup in Vienna!

The good news: DataStax ( has agreed to sponsor this premier!

We will kick-off at 7pm with the following agenda:

• Features and Use Cases (by Philipp Potisk)

Presentation abstracts
This presentations will be a short introduction about key-features and concepts of Cassandra. It will elaborate the strengths and weaknesses of the NoSQL database and so the audience will get a good feeling for which use cases this technology might be useful. The target audience of this presentation are techis, but more widely, for all who are interested how the big players, like Netflix, Ebay & co. are scaling out.

Quick presenter bios
Phil is a software engineer with more than 10 years of experience working with all kind of platforms and languages. In the last years, he was mainly focusing on J2EE and heavy-load systems. He is a DataStax Certified Cassandra Developer and is always interested in exchanging Apache Cassandra know-how with others.

• Usage of Cassandra at Xroadmedia ( (by Klaus Brunner)

Presentation abstracts
Xroadmedia's core product is a video content recommendation engine available as a cloud-based service (SaaS) and product (SaaP). Recommendation engines need to work with loads of data - quite a bit of which are customer-specific -, their usage intensity varies significantly over the course of a day, and they need to deliver results quickly anytime. On the other hand, they don't need the full transactional integrity of an air traffic control system. This maps quite well on what Cassandra promises, right? At XroadMedia, we've been working with Cassandra for about 2 years now, and we'll talk a bit about our experience - the good and the bad parts.

Quick presenter bios
Ever since waiting 25 minutes for a game to load from his C-64's datasette, Klaus has been interested in computing, data, and performance. He's a graduate of Vienna University of Technology and has been wrestling with Java for well over a decade.

• Developer Intro and Demos (by Gernot Bauer)

Presentation Abstracts
There is no good first meetup without a live demonstration of a Cassandra cluster - especially if you're new to this distributed database system. So we'll fire up a small Cassandra deployment and see what it looks like and what you can do with it.
And then we're gonna mess with the system. Because there is no better way to talk about a fault-tolerant database system than to actually try to break it. Right?

Quick presenter bios
Long before graduating from Graz University of Technology, Gernot has had strong interest in distributed applications. With several years of professional experience, he has mainly tackled the field of Java Enterprise development, garnished with quite a few applications that needed to be fault-tolerant and highly available.

We look forward to seeing many of you there!
