Michael Abbey’s user group forum presentation from OOW 12 … a link to my presentation from Oracle Open World 2012 … Oracle rman: Don’t Forget the Basics. Questions/comments/suggestions? Please contact me …
The consistent message, both from Oracle and from independent data architects has been: “Hadoop will not replace Oracle. Each system has its strengths and they can be used side by side to offer wider range of data storing and processing possibilities”.
It seems that most professionals understood and agreed with this message, because this year the question I am hearing most is “Which data should we store in Hadoop and which in Oracle”.
I can’t claim to have the definitive answer, but I can offer some pointers and start the discussion.
Some people call it day 1 but the user group forum on Sunday is so packed with information it is really day 1. The exhibit hall opened naturally on Monday and the chachka-hunters were out in force. I did my customary vendor hall walkabout with Greg for a bit and it was pretty much same-old same-old. I did not recognize all the booths but the ever-popular perennial vendors were everywhere to be seen. The evening was occupied by the Friends of Pythian event and it was well attended by colleagues, partners, and client representative.
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.
The day was action packed with sessions and I presented my Oracle rman:Don’t Forget the Basics to an enthusiastic crowd in Moscone west. The room was close to full with some hanging out at the back. It has been a while since I have presented in a room so close to being full. There was a handful of questions and comments during the session and a group of attendees approached me to follow-up afterwards.
Oracle CEO Larry Ellison has announced a new, smaller member to the Exadata X3 H2M2 family: the eighth rack. It’s targeted at environments that are too small for a quarter rack. Here are my thoughts.
Another interesting day today, I was attending the keynotes and I have found them quite interesting. Specially the way Tweeter use MySQL to build-up a nosql solution, jokes a side I take few notes on things I must analyze and dig in. Interesting one was also the introduction of the Paypal models, which brings me to attend the presentation later on. Presentation was well constructed and with some good theoretical work, but I was quite disappointed, I found the presentation incomplete, and missing real numbers for the MySQL Cluster NDB setup.
Tonight at Oracle OpenWorld, Oracle CEO Larry Ellison announced the latest Exadata release: X3. It sports a hardware refresh including a big expansion in RAM and flash storage capacity: 4TB and 22TB respectively on a full rack. Read my thoughts on this here.
One of Pythian’s clients in attendance was curious what Sunday at OOW is all about and I let the others in the lounge respond first then offered my 2 cents. There are actually two different perspectives from the presentations at OOW:
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.
