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…
Yesterday I provided a model for how business sees open source as a means to be profitable (here). This is the game Pivotal seems to be playing with their release of Hadoop, Gemfire, HAWQ, and Greenplum into open source. I do not know their real numbers… so they may need more or fewer additional customers than…
This post is more about the technology business than about technology… but it may be relevant as you try to sort out winners and losers… and this sort of sorting is important if you consider new companies who may, or may not, succeed in the long run. To make my point let us do a…
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…
In January Greenplum rolled out a new query optimizer. This is very cool and very advanced stuff. Query optimization is a search problem… in a perfect world you would search through the space of all possible plans for any query and choose the least expensive plan. But the time required to iterate through all possible…
Now for Greenplum & Hadoop… to continue this thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5, Part 6) 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 there…
