- I don't believe that ESP vs. CEP is the right type of partition in this area;
- There may be a need to have various implementation under one roof (the heterogeneous framework approach),
For the first point -- what is the right type of partition ? this is a multi-dimensional questions and we still have to learn more to know the most useful combinations.
One of the important dimensions is the "reason for use" dimension, and here in an internal IBM study we got to five different reasons to use, I'll write about it in one of the next postings.
EPTS has recently launched a workgroup that tries to identify these classifications by doing a comprehansive survey of use cases that will be compared using the same template. A team that consists of Tao Lin (SAP), Dieter Gawlick (Oracle) and Pedro Bizzaro (University of Coimbra, Portugal) is working on this template, and a larger team will handle this survey and analysis -- the end result - a collaborative white paper about the state of the practice in event processing is expected somewhere in the second quarter of 2008. Stay tuned.
More - Later.
