Competitive claims in CEP
For the most part, the vendors I talk with in complex event/stream processing like and speak well of each other (most of the exceptions seem to involve StreamBase). Even so, there are a lot of interesting competitive claims and counterclaims in this market. Prior posts and comment threads have covered Apama/StreamBase jousting on the subjects of who has more business and how many financial data feeds StreamBase supports. Other areas that generate interesting sparks are performance, parallelism, and determinism. Read more

The Coral8 story
Complex event/stream processing vendor Coral8 raised its hand and offered a briefing – non-technical, alas, but at least it was a start. Here are some of the highlights: Read more
Who’s who in columnar relational database management systems
The best known columnar RDBMS is surely Sybase’s IQ Accelerator, evolved from a product acquired in the mid-1990s. Problem – it doesn’t have a shared-nothing architecture of the sort needed to exploit grid/blade technology. Whoops. The other recognized player is SAND, but I don’t know a lot about them. Based on their website, it would seem that grids and compression play a big part in their story. Less established but pretty interesting is Kognitio, who are just beginning to make marketing noise outside the UK. SAP’s BI Accelerator is also a compressed columnar system, but operates entirely in-memory and hence is limited in possible database size. Mike Stonebraker’s startup Vertica is of course the new kid on the block, and there are other columnar startups as well whose names currently escape me.
