In the evening, over some wine, beer and cheese, there was a more informal session (no slides) in which different vendor representatives told us some lessons:
Marco Sierio from ruleCore started in eight lessons he devised in the train on his way, one of them is that people have hard time to adjust to the "event driven" thinking, since they are programmed to think in "request/response", Marco will probably put all eight lessons on his Blog, but one of the interesting lessons is that reading research papers is a time well spent, although it is not an easy task to do.
Richard Tibbetts from Streambase also provided some insights from his experience, ending with a statement that he did not see a lot of demand for pattern detection with his customers. Maybe in trading applications patterns detection is not a natural thing to do ?
Badrish Chandramouli from Microsoft provided some insights about StreamInsights. The interesting feature is the temporal model, which allow events to be defined as point event, interval event, and interval events with fuzzy boundaries. They also allow speculative computation and out-of-order processing, at least to some extent.
Alex Kozlenkov from Betfair, is both an user, and a developer of Prova, a self-made event processing platform, that follows the EPN/EPA model that we describe in the EPIA book (well - some variation of it) and explained its features in his usual enthusiastic way.
Martin Hirzel from IBM System S, talked about some of his impressions in working on that team, Martin is a programming languages person, working on the SPL (Stream Processing Language) and provided some insights about building a language by multi-disciplinary team.
Udo Pletat also from IBM, but from the software services organization, provided some insights on applying RFID oriented applications with customers (this is based on the Websphere Sensors Events product of IBM which has embedded Amit), and provided some examples of why they needed to use event processing patterns to track people's movement in chemical plants with restricted zones.
The session ended after 11pm and was very interesting gathering. Today -- the deep dive about "what is event processing" - more later.
