My last post (here) blathered about the effect that Hadoop must have on database vendor profits. An associate wrote me with the reminder that Hadoop is also impacting revenues and profits of ETL companies. If you think about Hadoop as both an inexpensive staging area for an EDW and as a parallel compute engine that can…
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…
Back to more geeky topics… although my Mom loved the videos… When very high performance is required to return key performance metrics derived from large volumes of data to a very large number of clients… in other words when volume and velocity are factors and the results are to be delivered to thousands of users (I…
Here are two videos of me speaking from the 2013 Intel Developer Forum FYI. The first has some technical detail: The second is more of a PR pitch about Intel Hadoop: I’m working with Intel on a new video with a pretty interesting storyline (at least I hope that you find it interesting?)… so stay…
For several years now I have been suggesting that Hadoop will squeeze the big data RDBMSs: Teradata, Exadata, Greenplum, and Netezza… squeezing them first out of the big data end of the market and then impinging on the high-end of the EDW space. Further I have suggested that there may be a significant and immediate TCO…
Recently I posted (here) some thinking that suggested that the cost of replicating data into specialized databases might outweigh the benefits of specialization. This post will present a counter view and try to sort out when a specialized database might make sense. In the ZDNet post here: “Look at What Google and Amazon are doing with…
In the first two post of this series (here and here) I first suggested that Hadoop could be effectively used as the platform for staging and then suggested that a modern warehouse would have a federation layer that turned it into a logical data warehouse. Figure 3 depicts this extended architecture. But if we have…
