XtremeData update
I talked with Geno Valente of XtremeData tonight. Highlights included:
- XtremeData still hasn’t sold any dbX stuff (they’ve had a side business in generic FPGA-based boards paying the bills for years). Well, there may have been some paid POCs (proofs of concept) or something, but real sales haven’t come through yet.
- XtremeData does have three prospects who have said “Yes”, and expects one order to come through this month.
- XtremeData continues to believe it shines when:
- Data models are complex
- In particular, there are complex joins
- In particular, two large tables have to be joined with each other, under circumstances where no product can avoid doing vast data redistribution
- XtremeData insists that all the nice things Bill Inmon – including in webinars — has said about it has not been for pay or other similar business compensation. That’s quite unusual.
- XtremeData is coming out with a new product, codenamed the Personal Data Warehouse (PDW), which:
- Is ready to go into beta test
- Should be launched in a month and a half or so
- Will have a different name when it is launched

Some NoSQL links
I plan to post a few things soon about MongoDB, Cassandra, and NoSQL in general. So I’m poking around a bit reading stuff on the subjects. Here are some links I found. Read more

Cassandra and the NoSQL scalable OLTP argument
Todd Hoff put up a provocative post on High Scalability called MySQL and Memcached: End of an Era? The post itself focuses on observations like:
- Facebook invented and is adopting Cassandra.
- Twitter is adopting Cassandra.
- Digg is adopting Cassandra.
- LinkedIn invented and is adopting Voldemort.
- Gee, it seems as if the super-scalable website biz has moved beyond MySQL/Memcached.
But in addition, he provides a lot of useful links, which DBMS-oriented folks such as myself might have previously overlooked. Read more

TwinFin(i) – Netezza’s version of a parallel analytic platform
Much like Aster Data did in Aster 4.0 and now Aster 4.5, Netezza is announcing a general parallel big data analytic platform strategy. It is called Netezza TwinFin(i), it is a chargeable option for the Netezza TwinFin appliance, and many announced details are on the vague side, with Netezza promising more clarity at or before its Enzee Universe conference in June. At a high level, the Aster and Netezza approaches compare/contrast as follows: Read more

Quick thoughts on the StreamBase Component Exchange
Streambase is announcing something called the StreamBase Component Exchange, for developers to exchange components to be used with the StreamBase engine, presumably on an open source basis. I simultaneously think:
- This is a good idea, and many software vendors should do it if they aren’t already.
- It’s no big deal.
For reasons why, let me quote an email I just sent to an inquiring reporter:
- StreamBase sells mainly to the financial services and intelligence community markets. Neither group will share much in the way of core algorithms.
- But both groups are pretty interested in open source software even so. (I think for both the price and customizability benefits.)
- Open source software commonly gets community contributions for connectors, adapters, and (national) language translations.
- But useful contributions in other areas are much rarer.
- Linden Labs is one of StreamBase’s few significant customers outside its two core markets.
- All of the above are consistent with the press release (which quotes only one StreamBase customer — guess who?).

Intelligent Enterprise’s Editors’/Editor’s Choice list for 2010
As he has before, Intelligent Enterprise Editor Doug Henschen
- Personally selected annual lists of 12 “Most influential” companies and 36 “Companies to watch” in analytics- and database-related sectors.
- Made it clear that these are his personal selections.
- Nonetheless has called it an Editors’ Choice list, rather than Editor’s Choice. 🙂
(Actually, he’s really called it an “award.”)
Comments on the Gartner 2009/2010 Data Warehouse Database Management System Magic Quadrant
February, 2011 edit: I’ve now commented on Gartner’s 2010 Data Warehouse Database Management System Magic Quadrant as well.
At intervals of a little over a year, Gartner Group publishes a Data Warehouse Database Management System Magic Quadrant. Gartner’s 2009 data warehouse DBMS Magic Quadrant — actually, January 2010 — is now out.* For many reasons, including those I noted in my comments on Gartner’s 2008 Data Warehouse DBMS Magic Quadrant, the Gartner quadrant pictures are a bad use of good research. Rather than rehash that this year, I’ll merely call out some points in the surrounding commentary that I find interesting or just plain strange. Read more
Netezza Skimmer
As I previously complained, last week wasn’t a very convenient time for me to have briefings. So when Netezza emailed to say it would release its new entry-level Skimmer appliance this morning, while I asked for and got a Friday afternoon briefing, I kept it quick and basic.
That said, highlights of my Netezza Skimmer briefing included:
- In essence, Netezza Skimmer is 1/3 of Netezza’s previously smallest appliance, for 1/3 the price.
- I.e., Netezza Skimmer has 1 S-blade and 9 disks, vs. 3 S-blades and 24 disks on the Netezza TwinFin 3.
- With 1 disk reserved as a hot spare, that boils down to a 1:1:1 ratio among CPU cores, FPGA cores, and 1-terabyte disks on Netezza skimmer. The same could pretty much be said of Netezza TwinFin, the occasional hot-spare disk notwithstanding.
- Netezza Skimmer costs $125K.
- With 2.8 or so TB of space for user data before compression, that’s right in line with the Netezza price point of slightly <$20K/terabyte of user data.
- That assumes Netezza’s usual 2.25X compression. I forgot to ask when 4X compression was actually being shipped.
- I forgot to ask, but it seems obvious that Netezza Skimmer uses identical or substantially similar components to Netezza TwinFin’s.
- Netezza Skimmer is 7 rack units high.
- In place of the SMP hosts on TwinFin Systems, Netezza Skimmer has a host blade.
- Netezza (specifically Phil Francisco) mentioned that when Kalido uses Netezza Skimmer for its appliance, there will be an additional host computer, but when it uses TwinFin for the same software, the built-in host will suffice. (Even so, I suspect it might be too strong to say that Skimmer’s built-in host computer is underpowered.)
- Netezza also suggested that more appliance OEMs are coming down the pike specifically focused on the affordable Skimmer.

Two cornerstones of Oracle’s database hardware strategy
After several months of careful optimization, Oracle managed to pick the most inconvenient* day possible for me to get an Exadata update from Juan Loaiza. But the call itself was long and fascinating, with the two main takeaways being:
- Oracle thinks flash memory is the most important hardware technology of the decade, one that could lead to Oracle being “bumped off” if they don’t get it right.
- Juan believes the “bulk” of Oracle’s business will move over to Exadata-like technology over the next 5-10 years. Numbers-wise, this seems to be based more on Exadata being a platform for consolidating an enterprise’s many Oracle databases than it is on Exadata running a few Especially Big Honking Database management tasks.
And by the way, Oracle doesn’t make its storage-tier software available to run on anything than Oracle-designed boxes. At the moment, that means Exadata Versions 1 and 2. Since Exadata is by far Oracle’s best DBMS offering (at least in theory), that means Oracle’s best database offering only runs on specific Oracle-sold hardware platforms. Read more
