Although not newsworthy enough for a press release, TIBCO’s engineering team recently released version 2.1 of its rule-driven CEP product, TIBCO BusinessEvents.
The main new feature of TIBCO BusinessEvents 2.1 is enhanced control of object persistence at runtime. Typically, in a rule-driven CEP engine you need to both store objects in memory (for the rule algorithm) and in cache (for long-term history, failover support, etc). The new feature allows the developer to set objects to be in cache + memory (the default), in-cache only, or in-memory only. This level of control allows applications to be tuned for maximum performance, by exploiting information such as that some objects may be transient (so why bother caching it), or only used in rare circumstances (so cache it and free up memory). Or you can leave everything as “normal”, which is cache + memory.
