Here is a quick review of tens years of data warehouse database competition… and a peek ahead… Maybe ten years ago Netezza shook up the DW DBMS market with a parallel database machine that could compete with Teradata. About six years ago Greenplum entered the market with a commodity-based product that was competitive… and then…
I have posted several times about the impact of the Hadoop eco-system on a several companies (here, here, here, for example). The topic cam up in a tweet thread a few weeks back… which prompts this quick note. Fours years ago the street price for a scalable, parallel, enterprise data warehouse platform was $US25K-$US35K per…
Teradata stock is falling hard due to guidance here that they may miss revenue targets. Analysts are downgrading the stock… but mostly from Buy to Neutral. Normally stock prices would not be a relevant topic for this blog… but in this case I believe that the Squeeze I suggested first in October of 2012 and…
My friend and a major contributor to the art of database architecture, Chuck McDevitt, died last week. Five years ago Chuck was diagnosed with an advanced cancer and given six months to live. He fought and endured and worked for most of those five years, teaching us all a little about how we might live…
I wondered here how IBM would position DB2 with BLU versus Netezza. Please have a look before you go on… and let me admit here and now that when I wrote this I chickened out. As I sat down this time I became convinced that I should predict the end of Netezza. Why? In the…
In my last post here I suggested that there were three levels of maturity around column orientation and described the first level, PAX, which provides columnar compression. This apparently is the level Exadata operates at with its Hybrid Columnar Compression. In this post we will consider the next two levels of maturity: early materialized column…
There are three forms of columnar-orientation currently deployed by database systems today. Each builds upon the next. The simplest form uses column-orientation to provide better data compression. The next level of maturity stores columnar data in separate structures to support columnar projection. The most mature implementations support a columnar database engine that performs relational algebra…
