Well as predicted, with Aster Data recently being picked up by Teradata most of the key new generation MPP distributed analytics vendors have been acquired (Aster Data, Vertica, Netezza & Greenplum). This had to happen and was expected to happen. The MPP Analytics startup “revolution” is over and these technologies will now be integrated into the mainstream.
So what’s next? As we now, if you are a massive multi-national software company it is a lot less risky to incrementally innovate and leave the development of “game changing” technologies to startups that can be acquired after they prove both the tech and the market. So what follows MPP? …

There are so, so many big data platforms in play at the moment it can be confusing for developers to know where to start. For startups it used to be simple, MySQL, but dust clouds were created when all the NoSQL platforms started to crash the party 18 months or so ago. But I do see the dust begin to settle and we are starting to see some market “leaders” appear. A very unscientific approach is to list the technologies I hear about in the “big data startup” world on a daily basis. These are, in no particular order:
- MySQL - yes it is still very much hanging in there despite the Oracle acquisition. MySQL has been helped by technologies such as AWS RDS and Xeround making it more digestible for big data startups who want to minimize operational overheads.

IBM's Watson natural language Question & Answer system made headlines recently with its primetime debut on Jeopardy. Despite a few embarassing answers, Watson trounced top Jeopardy players Brad Rutter and Ken Jennings. Watson is built from 90 IBM Power 750 IBM Linux servers with 16 terabytes of memory providing 80 Teraflops of processing power. Watson is perhaps the most famous "Big Data" systems out there.

Cloudera Instructor Tom Hanlon will be presenting a free
class on Hadoop Tuesday March 15th on Dallas. Tom is a familiar
face to MySQLers in the North Texas area having previous taught
many MySQL classes. Pizza and Drinks will be provided.
This will be an excellent opportunity for MySQL DBAs to learn
from booth a MySQL and Hadoop expert. Hadoop is a computational
paradigm named Map/Reduce, where the application is divided into
many small fragments of work which may be executed any node in
the cluster.
