Analytics with Cassandra and Spark SQL Workshop

For those that learned about Apache Cassandra, you have realized so far that Cassandra it’s a storage and pre-aggregation layer, thus a computational layer should exist in order to complete the queries we would like to run on our data. In this workshop we will look at the analytics that can be done on top of Cassandra with Spark SQL, we will start with similar examples in CQL and Spark SQL and we will evolve into examples that can only be run with Spark SQL.

Registration should be made separately for each workshop.

1. Getting started with Spark: intro and hands on session, in the limit of 20 places

Spark is the new trend in big data technologies, offering us an easy API and multiple environments to work with, like Batch, SQL, Graph, Machine Learning and Streaming processing.

The workshop will start with an introduction in Spark and will continue with many Spark examples, including the well known Wordcount example.

You have the option to choose the programming language you are most familiar with, so the examples will be written and explained in Java, Scala and Python (to be confirmed the Java one).

We will try all Spark examples in local mode, so all you need is your own laptop. The major benefit of this is that you can continue learning and try new examples even after the workshop.

Big Data in Tg Mures

Looks like Big Data topic is getting more and more attention and more cities are starting events that include this topic, thus we decided we will have a new page where we will present these events. The first event we will feature will take place in Tg Mures on June 2nd, Kodok Marton will talk about “Complex Realtime Event Analytics Using BigQuery”.

Join the event if you are in the Tg Mures area, you can see the event details here.

Looking forward to see a Big Data community forming in Tg Mures as well.

Hadoop MapReduce and Spark training

With the occasion of completing the Big Data Romanian Tour in Bucharest we planned a light intro and hands-on session for MapReduce and Spark. Together with the trainers – Tudor Lapusan and Andrei Avramescu – we are planning a dynamic and interactive session that is going to go from theory to practice. We have only 4 hours so we will need to be pretty fast – thus we will send in advance some materials to get familiar to. But, the good thing is that at the end of this session you should be able to start your own Hadoop or Spark cluster, pump data into it and start the analysis. Tudor and Andrei will also talk about the differences between Spark and Hadoop MapReduce. We will have a limited number of places available for this training – since we will need to work with everybody on the hands on part of the training – thus, if you are interested, don’t wait up. Register here for the training and tell us your expectations so that we can prepare better in advance. See you all soon & if you have any questions contact us on contact at or comment this post.

Romanian Big Data Roadshow: Cluj, Timisoara, Bucharest

colaj big data meetups

3 Romanian communities, more then 700 members, incredible energy and subjects, these are just a few of the ingredients of the Romanian Big Data Roadshow that brings together speakers and members of three dynamic communities that have in common an extremely high interest in Big Data & Data Science.

A bit of a background for the event 

I met (virtually) Alex Sisu and Tudor Lapusan, the organizers for Timisoara and Cluj Big Data meetups, early 2014 and was not long after that we decided we need to organize a Big Data event, given:

– the amount of knowledge but also of interest that exists in Romania on this particular area

– but as well our similar thoughts on keeping such events technology/companies independent as much as possible, in order keep the content genuine and not transform presentations in sales pitches.

To get started and see how our collaboration goes first we started with this roadshow. Follow us on this page (or on the respective pages of the local communities for the detailed agendas, presentations, pictures) and see how the roadshow looks like, but as well stay tuned for what we’re planning next.
