Six things to make your Big Data project succeed

So I wrote about why your Hadoop project will fail so I think its only right that I should follow up with some things that you can do to actually make the Big Data project you take on succeed.  The first thing you need to do is stop trying to make 'Big Data' succeed and instead start focusing on how you educate the business on the value of information and then work out how to deliver new (more...)

The Twelve Days of NoSQL: Day Ten: Big Data

On the tenth day of Christmas, my true love gave to me Ten lords a-leaping. The topic of Big Data is often encountered when talking about NoSQL so let’s give it a nod. In 1998, Sergey Brin and Larry Page invented an algorithm for ranking web pages (The Anatomy of a Large-Scale Hypertextual Web Search […]

My history with Big Data

Before I joined Cloudera, I hadn't had much formal experience with Big Data. But I had crossed paths with one of its major use cases before, so I found it easy to pick up the mindset. My previous big project involved a relational database hooked up to a web server. (more...)

RDBMS and their bundle-mates

Relational DBMS used to be fairly straightforward product suites, which boiled down to:

  • A big SQL interpreter.
  • A bunch of administrative and operational tools.
  • Some very optional add-ons, often including an application development tool.

Now, however, most RDBMS are sold as part of something bigger.

Comments on the 2013 Gartner Magic Quadrant for Operational Database Management Systems

The 2013 Gartner Magic Quadrant for Operational Database Management Systems is out. “Operational” seems to be Gartner’s term for what I call short-request, in each case the point being that OLTP (OnLine Transaction Processing) is dubious term when systems omit strict consistency, and when even strictly consistent systems may (more...)

My Strata + Hadoop World Schedule

Next week is Strata + Hadoop World which is bound to be exciting for those who deal with big data on a daily basis.  I’ll be spending my time talking about Cloudera Impala at various places so I’m posting my schedule for those interesting in catching about fast SQL on (more...)

Cloudera Sentry and other security subjects

I chatted with Charles Zedlewski of Cloudera on Thursday about security — especially Cloudera’s new offering Sentry — and other Hadoop subjects.

Sentry is:

  • Developed by Cloudera.
  • An Apache incubator project.
  • Slated to be rolled into CDH — Cloudera’s Hadoop distribution — over the next couple of weeks.
  • Only useful (more...)

Upcoming Talks: OakTable World and Strata + Hadoop World

I haven’t had much time over the past year to do many blog posts, but in the next few months I’ll be doing a few talks about what I’ve been working on over that time, Cloudera Impala, an Open Source MPP SQL query engine for Hadoop.  Hope to see (more...)

“Disruption” in the software industry

I lampoon the word “disruptive” for being badly overused. On the other hand, I often refer to the concept myself. Perhaps I should clarify. :)

You probably know that the modern concept of disruption comes from Clayton Christensen, specifically in The Innovator’s Dilemma and its sequel, The Innovator’s Solution. The basic (more...)

Demystifying Big Data for Oracle Professionals

Ever wonder about Big Data and what exactly it means, especially if you are already an Oracle Database professional? Or, do you get lost in the jargon warfare that spews out terms like Hadoop, Map/Reduce and HDFS? In this post I will attempt to explain these terms from the perspective (more...)

The 3 ways Hadoop will change your Business Intelligence

“It’s the analytics stupid!” Obviously the offense is not intended at the dear reader. It’s a wake up call for all the people excited with Hadoop and lack BI vision. The BI people that lack infrastructure vision are also to blame. Blame for what? We’ll see later in this (more...)

InfoQ : Running the Largest Hadoop DFS Cluster

Since I joined a Big Data Event : Frankfurter Datenbanktage 2013 - I started to take also a look to non-relational technics too. The RDBMS is not for every asepct the correct and fitting and fulfilling answer to all data related IT challenges.

What’s all the fuss about Big Data?


Big Data is the collective term for very large and potentially complex data sets that are deemed to be so large that it’s difficult to handle the data using traditional tools and applications such as Relational Database Management Systems. Scientists in the fields of physics, genetics and meteorology were previous examples of those that encountered Big Data.

 

However,

Everything you ever wanted to know about Big Data, but had no PDF to carry around!

Back in March 2012 I experienced an air milage overflow: almost straight from Madrid I’ve picked a flight to Israel to speak at a Big Data conference, only to be back in Lisbon and fly again to Johannesburg in South Africa to meet several customers in the retail and manufacturing area. Back to Lisbon I packed again to London [...]
