… was the subject of today’s Forrester-IBM webinar on distributed cache technology, with both Forrester and IBM citing CEP and EDA as users for this technology, amongst others. The overriding driver for this tech being eXtreme Transaction Processing, which we might just refactor as eXtreme Event Processing for the purposes of this blog!
One minor quibble: John Rymer of Forrester did the introduction and during so classified the cache market as .NET, Java and NoSQL camps, with TIBCO placed in the Java camp. This might seem a fair classification of a complex market area, but of the 2 relevant TIBCO distributed cache offerings:
- TIBCO BusinessEvents, although Java-based, is more accurately described as a CEP product that embeds a distributed cache – it wouldn’t normally appear on a vendor list of distributed cache technologies;
- TIBCO ActiveSpaces is more accurately described as a data grid, but has .NET, C and Java interfaces. I’m sure other caching / data grid products have similar multiple interfaces – after all the client is just “an interface” to the cache / grid.
Spare a thought in passing, though, for the OODBMS guys. Amongst this buzz about data grids and caching, I notice the Forrester blog is reporting that the Progress guys (disclosure: a TIBCO competitor in some areas) are now considering their ObjectStore OODBMS a “legacy platform”. Plus ça change, perhaps.
