An empirical comparison of graph databases

In this blog post we briefly describe our new contribution to the big data domain, especially, graphDB benchmarking. This work was accepted for publication at 2013 ASE/IEEE International Conference on Big Data.

In this work, we presented a distributed graph database benchmarking framework. We used this tool to analyze the performance of four graph databases: Neo4j 1.9M05 , Titan 0.3, OrientDB 1.3 and DEX 4.7.

Smartphone-market

First let’s take a sneak peek at the smartphone market:

  • the LG G2  which should be the base for the next Google Nexus (5?).
  • the Samsung Galaxy Note 3, the latest iteration of the well known Phablet.
  • the Sony Xperia Z1, the latest flagship from Sony with a massive camera (20,1 mégapixels F 2.0).
  • Apple’s iPhone 5C, a colorful iPhone 5 with a plastic shell.
  • Apple’s iPhone 5s, the first phone with a 64bit processor.
  • the Oppo N1, a Chinese smartphone that officially supports CyanogenMod, the popular Android alternative Rom.

OpenNebula Conference

Open-nebula

And then it’s over, 3 days at the 1st OpenNebula Conference! I took part in 18 talks, put my hands into OpenNebula core, met a lot of interesting people, enjoyed a really nice German dinner in the capital and filled my brain with tons of information and inspiration.

ASE/IEEE Big Data Washington 2013

Hammer

This week I had the chance to attend the ASE/IEEE International conference on Big Data here in Washington DC. EURA NOVA’s presence has been highly remarked as we had two papers: imGraph (big up to @AldemarReynaga) and a paper presenting our empirical performance analysis on some of the major graph database on the current market.

DEXA, DaWaK 2013

I spent the last week at Prague, Czech Republic, to present my paper entitled “An Analytics-Aware Conceptual Model For Evolving Graphs”. More details on the paper could be found in my previous article.

In this post I will focus more on the trends, and share some of the lessons I learned during this nice travel.

The Dirty Dozen

the-dirty-dozen-1

While it’s not necessary to be dirty, this film tells us one clear thing: you’re stronger with a small team of specialists rather than with a big group of clones. More: you can achieve impossible missions.

We can observe this in innovation every time it comes to reach great, ambitious, disruptive business objectives. It’s a matter of mastering the market context, the behavior of the customers, the way value can be created, to go outside the standard tracks, to know the channels to reach your targets and to exploit every single advantage you have in front of your competitors, might it be in term of timing, vision or technology.

Brussels Cassandra Users

Cassandra

This last Tuesday EURA NOVA hosted an interesting Cassandra meetup. Several tech enthusiasts and Cassandra fans have met each other for two talks: I briefly introduced what are the challenges and potential solution when building a distributed graph layer on top of Cassandra, the second talk, presented by Ansar Rafique,  was a general introduction to Cassandra and some performance comparisons against MySQL. Ansar is a PhD student at the department of Computer Science of the Katholieke Universiteit Leuven – Language technology and middleware taskforce (LANTAM) of the DistriNet research group. The talk presented the result of Ansar’s previous researches at Cinnober Financial Technology about factors influencing Read/Write operation in MySQL and Cassandra.

“When you hold a hammer, everything begins to look like a nail!”

A few weeks ago, while we were building our high performance computing grid over Graphical Process Unit (GPU), @Nam-Luc enunciated this sentence in order to spotlight one of the most crucial element in a project, whatever it is: the potential irreversibility of a tool choice.

EBISS 2013 @Dagstuhl

This week I was with Amine and Gary at the 3rd European Business Intelligence Summer School organized in the beautiful Dagstuhl castle in Germany. I was present at the two previous editions, it is a great way to have a condensed overview of top-level research in BI. This year two aspects have caught my attention: (1) the ever increasing skills required to be a good “data worker” and (2) the everlasting ontology and semantic web power.

June was also a very prolific month for tech-related news: the E3, the WWDC where the brand new iOS and MacOS were presented along with an impressive new Mac Pro. Even Huawei chose this month the enter the crowed place of high-end smartphone manufacturers with its P6: “the world thinest smartphone” (so far).

A Conceptual Model For Evolving Graphs Analysis

Currently EURA NOVA is leading two PhD thesis in collaboration with the CODE/WIT Lab of the Université Libre de Bruxelles. Both thesis are supervised by Professor Esteban Zimànyi from ULB and Sabri Skhiri from EURA NOVA.

The goal of my thesis is to build a multidimensional analysis framework on top of NoSQL data, and most importantly Graphs. Recently our paper entitled: An Analytics-Aware Conceptual Model For Evolving Graphs was accepted for presentation on the 15th International Conference on Data Warehousing and Knowledge Discovery – DaWaK 2013. The conference will be held in Prague, Czech Republic from 26 to 29 August 2013. DaWaK is a reference conference on data warehousing bringing together researcher working on BI related topics.

In this post, I’ll give an overview of the research and contributions of this paper.

Impossibility of change?

As time goes by and information technologies infrastructures are built, historical decisions accumulate. This accumulation put constraints on architectural options for the future. In other words, the more history you have to manage, the less time you have to make your system progress. And time is money.

Innovative Cross-Pollination

collaborate-2

In the natural world, cross-pollination occurs when a bird or bee delivers one flower’s pollen to a different plant. In the same way, innovation occurs when people bring ideas from one place to another. By its special position within his clients’ organisation, EURA NOVA’s experts are in that way a factor of innovation by simply cross-pollinating EURA NOVA’s knowledge.

This month was a very interesting month for Tech related news. I would have loved to talk about the new Jolla’s phone and the ‘Other Half’, the XBOX ONE, Marissa Mayer’s Yahoo, BBC’s Perceptive Radio or even Google I/O.
But instead I will write about the rise of Instant Messaging Apps.
