Here is a short story about distributed versus monolithic application design… Around 1999 Dan Holle and I started thinking about how to better deploy applications that used distributed computing. To be fair… Dan schooled me on his ideas for a better approach. We started with a thing called XML that had not yet released a…
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…
This is the second post (see Part 1 here) on how vendors adjust their architecture without admitting that the previous architecture was flawed. This time we’ll consider Teradata and in-memory…. When SAP HANA appeared Teradata went on the warpath with a series of posts and statements that were pointed but oddly miscued (see the references below).…
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…
I’m working on a new idea… it may or may not pan out… but here are some concepts for your consideration… with some thoughts on their performance implications. First a reminder… a reality check. In my experience if you POC two databases at about the same price point…and one is 30% faster than the other, 1.3X, then…
Now for SQL Server… continuing the thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7) I have suggested that we could evaluate integration architecture using three criteria: How parallel are the pipes to move data between the RDBMS and the parallel file system; Is there intelligence to push down predicates; and Is…
