There always seems to be a fire drill around MapReduce news
Last August I flew out to see my new clients at Greenplum. They told me they planned to roll out MapReduce in a few weeks, and asked for my help in publicizing it. From their offices I went to dinner with non-clients Aster Data, who told me they’d gotten wind of a Greenplum MapReduce announcement and planned to come out ahead of it. A couple of hours later, Aster signed up as a client. In something of a pickle — but not one of my own making — I knocked heads, and persuaded both vendors to announce MapReduce at the same time, namely the following Monday. Lots of publicity ensued for both vendors, and everybody was reasonably satisfied. Read more

Lots of analytic DBMS vendors are hiring
After writing about a Twitter jobs page, it occurred to me to check out whether analytic DBMS vendors are still hiring. Based on the Careers pages on their websites, I determined that Aster, Greenplum, Kickfire, and ParAccel all evidently are, in various mixes of (mainly) technical and field positions. At that point I got bored and stopped.
I didn’t choose those vendors entirely at random. If I had to name three vendors who are said to have had small layoffs at some point over the past few quarters, it would be ParAccel, Greenplum, and Kickfire. So if even they are hiring, the analytic DBMS sector is still pretty healthy … or at least thinks it is. 😉

Fox Interactive Media’s multi-hundred terabyte database running on Greenplum
Greenplum’s largest named account is Fox Interactive Media — the parent organization of MySpace — which has a multi-hundred terabyte database that it uses for hardcore data mining/analytics. Greenplum has been engaging in regrettable business practices, claiming that it is in the process of supplanting Aster Data at Fox/MySpace. In fact, MySpace’s use of Aster is more mission-critical than Fox’s use of Greenplum, and is increasing significantly.
Still, as Greenplum’s gushing customer video with Fox Interactive Media* illustrates, the Fox/Greenplum database is impressive on its own merits. Read more

MySpace’s multi-hundred terabyte database running on Aster Data
Aster Data has put up a blog post embedding and summarizing a video about its MySpace account. Basic metrics include:
The combined Aster deployment now has 200+ commodity hardware servers working together to manage 200+ TB of data that is growing at 2-3TB per day by collecting 7-10B events that happen on one of the world.
I’m pretty sure that’s counting correctly (i.e., user data).* Read more

MapReduce user eHarmony chose Netezza over Aster or Greenplum
Depending on which IDG reporter you believe, eHarmony has either 4 TB of data or more than 12 TB, stored in Oracle but now analyzed on Netezza. Interestingly, eHarmony is a Hadoop/MapReduce shop, but chose Netezza over Aster Data or Greenplum even so. Price was apparently an important aspect of the purchase decision. Netezza also seems to have had a very smooth POC. Read more

An example of Aster Data’s nPath/MapReduce syntax
Perhaps in response to my prior post on Aster Data’s introduction of MapReduce-based nPath, Steve Wooledge of Aster offers a more detailed example. The particular case he works through is:
… the question: for SEO/SEM-driven traffic that stay on our site only for 5 or less pageviews and then leave our site and never return in the same session, what are the top referring search queries and what are the top path of navigated pages on our site?

Aster Data nPath
Edit: Unfortunately, this post and its sequel rely on Aster Data posts that Aster’s buyer Teradata no longer makes easily available.
At the same time as it rolled out its cloud story, Aster Data told of nPath, a MapReduce-based feature in nCluster. As best I understand it, the core idea of nPath is that it preprocesses sequential data via MapReduce so that you can then do ordinary SQL on it. (Steve Wooledge’s blog post about nPath outlines why that might be needed. Point 1 in Mayank Bawa’s August, 2008 post is much more concise. 😉 ) Now, that might seem to contradict the syntax, which is all about MapReduce being invoked via SQL — still, it’s what’s really going on.
That leads to two obvious questions: What is nPath used (or useful) for? and How is the preprocessing done anyway? Read more

Aster Data in the cloud
Aster Data is in the news, bragging about a cloud version of nCluster, and providing both a press release and a blog post on the subject. It seems there are three actual customers, two of which have been publicly named. One of them, ShareThis, is in production. (2 terabytes of data on 9 nodes, planning to scale to 10-18 TB on 24 or so nodes by year-end.) All seem to be doing something in the area of internet marketing, web analytics or otherwise — which makes sense, as the same could be said of almost all Aster customers overall. That said, it seems that these customers are doing their primary analytic processing remotely, which makes Aster’s experience in that regard more akin to Kognitio’s than to Vertica’s. Read more

Draft slides on how to select an analytic DBMS
I need to finalize an already-too-long slide deck on how to select an analytic DBMS by late Thursday night. Anybody see something I’m overlooking, or just plain got wrong?
Edit: The slides have now been finalized.
One vendor’s trash is another’s treasure
A few months ago, CEO Mayank Bawa of Aster Data commented to me on his surprise at how “profound” the relationship was between design choices in one aspect of a data warehouse DBMS and choices in other parts. The word choice in that was all Mayank, but the underlying thought is one I’ve long shared, and that I’m certain architects of many analytic DBMS share as well.
For that matter, the observation is no doubt true in many other product categories as well. But in the analytic database management arena, where there are literally 10-20+ competitors with different, non-stupid approaches, it seems most particularly valid. Here are some examples of what I mean. Read more
