Patent nonsense: Parallel Iron/HDFS edition

Alan Scott commented with concern about Parallel Iron’s patent lawsuit attacking HDFS (Hadoop Distributed File System), filed in — where else? — Eastern Texas. The patent in question — US 7,415,565 — seems to in essence cover any shared-nothing block storage that exploits a “configurable switch fabric”; indeed, it’s more oriented to OLTP (OnLine Transaction Processing) than to analytics. For example, the Background section starts: Read more

Alternatives for Hadoop/MapReduce data storage and management

There’s been a flurry of announcements recently in the Hadoop world. Much of it has been concentrated on Hadoop data storage and management. This is understandable, since HDFS (Hadoop Distributed File System) is quite a young (i.e. immature) system, with much strengthening and Bottleneck Whack-A-Mole remaining in its future.

Known HDFS and Hadoop data storage and management issues include but are not limited to:

Different entities have different ideas about how such deficiencies should be addressed.  Read more

In-memory, parallel, not-in-database SAS HPA does make sense after all

I talked with SAS about its new approach to parallel modeling. The two key points are:

The whole thing is called SAS HPA (High-Performance Analytics), in an obvious reference to HPC (High-Performance Computing). It will run initially on RAM-heavy appliances from Teradata and EMC Greenplum.

A lot of what’s going on here is that SAS found it annoyingly difficult to parallelize modeling within the framework of a massively parallel DBMS such as Teradata. Notes on that aspect include:

Unpacking the EMC Greenplum Q1 sales disaster rumors

A well-connected tipster believes:

In the past I might have called Greenplum for clarification, but they’re not knocking themselves out to inform me these days, nor to inspire me with confidence in what they say.  Read more

Comments on EMC Greenplum

I am annoyed with my former friends at Greenplum, who took umbrage at a brief sentence I wrote in October, namely “eBay has thrown out Greenplum“.  Their reaction included:

The last one really hurt, because in trusting them, I put in quite a bit of effort, and discussed their promise with quite a few other people.

Comments on the Gartner 2010/2011 Data Warehouse Database Management Systems Magic Quadrant

Edit: Comments on the February, 2012 Gartner Magic Quadrant for Data Warehouse Database Management Systems — and on the companies reviewed in it — are now up.

The Gartner 2010 Data Warehouse Database Management Systems Magic Quadrant is out. I shall now comment, just as I did to varying degrees on the 2009, 2008, 2007, and 2006 Gartner Data Warehouse Database Management System Magic Quadrants.

Note: Links to Gartner Magic Quadrants tend to be unstable. Please alert me if any problems arise; I’ll edit accordingly.

In my comments on the 2008 Gartner Data Warehouse Database Management Systems Magic Quadrant, I observed that Gartner’s “completeness of vision” scores were generally pretty reasonable, but their “ability to execute” rankings were somewhat bizarre; the same remains true this year. For example, Gartner ranks Ingres higher by that metric than Vertica, Aster Data, ParAccel, or Infobright. Yet each of those companies is growing nicely and delivering products that meet serious cutting-edge analytic DBMS needs, neither of which has been true of Ingres since about 1987.  Read more

ParAccel PADB technical notes

I posted last October about PADB (ParAccel Analytic DataBase), but held back on various topics since PADB 3.0 was still under NDA. By the time PADB 3.0 was released, I was on blogging hiatus. Let’s do a bit of ParAccel catch-up now.

One big part of PADB 3.0 was an analytics extensibility framework. If we match PADB against my recent analytic computing system checklistRead more
