A few months ago I posted an article on the blog around using Apache Spark to analyse activity on our website, using Spark to join the site activity to some reference tables for some one-off analysis. In this article I’ll be taking an initial look at Spark Streaming, a component within the overall Spark platform that allows you to ingest and process data in near real-time whilst keeping the same overall code-based as your (more...)
Over the past couple of years we have had a lot of information about Big Data presented to us. But one of the things that still stands out is that there is still a bit of confusion on what Big Data is. Depending on who you are talking to you will get a different definition and interpretation of what Big Data is and what you can do with it.
For example there is one company (more...)
I think this is cool as it gives you the ability to use SQL on an HBase table.
To test this, let's say you login to HBase and you create an HBase table like (more...)
Here is a post about another project in the Big Data world, like Apache Hive from my previous post, enables you to do SQL on Big Data. It is called Apache Phoenix.
It explains what we see is coming, at a high level, from long time Oracle database professionals’ viewpoint and using database terminology (as the E4 audience is all Oracle users like us).
However, this change is not really about Oracle database world, it’s about a much wider shift in enterprise computing: modern Hadoop data lakes and clouds are here to stay. They are already taking over many workloads traditionally executed on (more...)
In this post I will share my experience with an Apache Hadoop component called Hive which enables you to do SQL on an Apache Hadoop Big Data cluster.
Being a great fun of SQL and relational databases, this was my opportunity to set up a mechanism where I could transfer some (a lot) data from a relational database into Hadoop and query it with SQL. Not a very difficult thing to do these days, actually (more...)
ODTUG KScope’15 is running in Hollywood, Florida next week and Rittman Mead are running a number of sessions during the week on OBIEE, Essbase, ODI and Big Data. I’ve personally been attending ODTUG KScope (or “Kaleidoscope”, as it used to be known) for many years now and it’s the best developer-centric conference we go to, coupled with amazing venues and a great community atmosphere.
Sessions we’re running over the week include:
- Gianni Ceresa : 2-in-1: (more...)
I have some news, two items actually.
First, today (it’s still 18th June in California) is my blog’s 8th anniversary!
I wrote my first blog post, about Advanced Oracle Troubleshooting, exactly 8 years ago, on 18th June 2007 and have written 229 blog posts since. I had started writing and accumulating my TPT script collection a couple of years earlier and now it has over 1000 files in it! And no, I don’t remember (more...)
Virtual machines (VM) are not new –it has been around for quite some time, and as a consultant I find myself use them all the time. As a matter of fact, just on my laptop and external drive there are at least 15 or 20 different virtual environment which I use for testing, experimenting, and for creating new blog posts.
The thing with virtual machines that you need to be a little more than just (more...)
We will be presenting the Sonra Hadoop Quick Start Appliance at CeBIT next week in Hanover. Meet and greet us in Hall 2, Stand D52 (C58).
At Sonra we understand the difficulties faced by businesses when they begin their Big Data journey. We help you get started in days or weeks and immediately reap the benefits of Big Data. Sonra have packaged optimised Hadoop Supermicro hardware with MapR, the prime Hadoop distribution, and added our (more...)
For those of you who missed the event I have posted some pictures below. We have recorded (more...)
Join MapR and Sonra for the Hadoop User Group Ireland Meetup on 23 February at 6 pm at the Wayra offices (O2/Three building). You’ll learn more about the MapR distribution for Apache Hadoop through use cases, case studies and an introduction to the benefits of using the MapR platform.
Come by for this content-packed first event ending with the opportunity to socialise over beer and pizza kindly provided by Sonra.
What is (more...)
I have been patching engineered systems since the launch of the Exadata V2 and recently i had the opportunity to patch the BDA we have in house. As far as comparisons go, this is were the similarities stop between Exadata and a Big Data Appliance (BDA) patching.
Our BDA is a so called startes rack consisting of 6 nodes running a hadoop cluster, for more information about this read my First Impressions blog post. On (more...)
Voor februari 2015 staan er diverse presentaties op de planning met name op het gebied van architectuur en agile:
Kennissesies agile architectuur bij Ordina
Op 5 februari organiseert Ordina een kennissessie over agile architectuur in de praktijk. Net als op het LAC zal ik een presentatie houden over de waarde van architectuur en time-to-market. Waarin ik laat zien dat juist architectuur waarde en snelheid kan bieden bij de time-to-market. Dit aan de (more...)
