Following my “Building Integrated DWH with Oracle and Hadoop” webinar for IOUG Big Data SIG, I got a bunch of excellent follow up questions. The most frequently asked questions are: What is the minimum I need to do to get started with Hadoop? and How do I load data into Hadoop? Since so many people are interested in the same question, it makes more sense to answer on the blog.

Shortly before we all went on break for the holiday, Oracle announced the new BDA X3-2. Now I have time to properly sit down with a glass of fine scotch and dig into the details of what is included in the release. Turns out that there are quite a few changes packed in. We are getting new hardware, new Hadoop, new Connectors and new NoSQL. Tons of awesome features are included. Let’s get into it.

This Log Buffer Edition has covers everything that happening at Oracle Open World and more in Log Buffer #289.

Tuesday morning at OOW is always occupied by this forum, an opportunity for authors and other persons to receive heads up on what’s coming down the pipe from Oracle. The following notes are musings from yours truly as I attended the forum today.

I attend five sessions today and I think some of them were very interesting. Like the one on the Optimizer insight, quite informative and accurate.
The other one done by the MySQL Cluster (NDB) group on the installer and new Javascript API interface, left me a little bit … foggy. Why? Because in my mind one of the most important thing to accomplish in NDB is the correct dimensioning of the memory, buffers, possible operation, attributes and so on, all things that should come from the review of the schema definition review and from the application analysis.

It is exciting to be here, meeting again old friends and ex colleagues, but also exciting for what seems the start of a very significant conference fro MySQL. I really enjoy the introductions done from Edward Screven and Thomas Ulin. Edward highlight the fact that MySQL is increasing his presence in the market and in the community. This could be also thanks to the unbelievable effort done by Oracle in keeping his production cycle on target.

Recently I was tasked with setting up an HBase cluster to test compared against Amazon’s DynamoDB offering. The client had tested that it worked well for up to 10k updates/sec, but were concerned about the cost. I set up a…

What is Ansible? Ansible is a configuration management and deployment system, like Puppet, Capistrano, Fabric, and Chef. Its aim is to be radically simple and let you use your existing scripts to help with cluster configuration and software deployment whenever possible….

The traditional NoCOUG SQL challenge has been launched this year with a twist: In the wake of the “BigData” trend/buzz, it’s now been upgraded to a “SQL and/vs. NoSQL” challenge. I took on the challenge, treading through my SQL comfort zone and thinking of ways I could bend relational algebra to solve the wicked puzzle suggested this year.

The Ottawa Oracle User Group (OOUG) was kind enough to invite me to give presentations for a whole morning. The group was ultra engaged and asked a lot of good questions, so my usual 50-minute Big Data presentation ended up taking 100 minutes, and the rest of the content had to be squeezed a bit. I hope everyone had a good time!
