I agree that these gentlemen are top notch researchers, witnessed by the fact that the authors do not mention nor claim to be “complex event processing” anywhere in their paper!  This paper is not about CEP, nor does it claim to be about CEP, it is about stream processing and unifying SQL standards.

ABSTRACT: This paper describes a unification of two different SQL extensions for streams and its associated semantics. We use the data models from Oracle and StreamBase as our examples. Oracle uses a time-based execution model while StreamBase uses a tuple-based execution model. Time-based execution provides a way to model simultaneity while tuple-based execution provides a way to react to primitive events as soon as they are seen by the system.

Asmentioned on numerous occasions, stream processing is a very important area in CEP/EP.   It is important not to confuse the higher situational knowledge from object-object correlation and state management with the single-object event refinement that occurs in stream processsing.    Event stream processing is fundamentally different than complex event processing. 

Event stream processing performs operations on streaming event objects.   In almost all advanced CEP/EP applications is is necessary to perform robust track and trace operations on streaming event objects, like tracking the position of an airplane.    Tracking the position of an aircraft can be modelled very nicely with event stream processing.  Tracking individual event objects is a precuror to multiclass object situation refinement.

When we manage the state of all the aircraft in the skies over New York, you need more than a stream processing construct.  You need to manage the state of all the aircraft.  Paul Vincent of TIBCO Software being to address this important point in The Value of State…  

Again, we will be better equiped to solve complex distributed event processing problems if we do not confuse the notion of event stream processing and complex event processing.   These technologies are indeed complimentary, both very important, but they are not the same.

I applaud Oracle and StreamBase’s work toward a unified standard for SQL extensions for streams.

As we get closer to the conference dates, I wish that I had made plans to fly back to the US to meet everyone.    However, I have been cutting back on public speaking, taking a break since May.  In addition, Gartner did not ask me to speak at their Event Processing Summit this year, I assume because they did not want to pay airfare for my flight from Thailand to the US.    Also, Gartner always likes to fill their conference speaking slots with as many Gartner speakers as they can, unless you are a paid sponsor; and I noticed a number of Gartner employees speaking in multiple slots.

(Editorial Note) Then again, maybe I complained to much about the lack of organization and conference problems when I was invited at be a Gartner keynote speaker last time - reservations not made propertly,  problems with the guest speaker registration list at sign-in, rooms shifted without notifying the speakers and panelists.   Admittedly, I was not happy with the conference organizers at the last get together.  This was my fault, as I am accustomed to better conference execution and am probally too “picky” about details these days - my bad.  Anyway, the Gartner organizers apologized numerous times, saying they had too many conferences going on at the same time and not enough people to cover them all.

One of the problems with spending so much time in Asia, especially in Thailand, is that guest speakers are really treated as VIPs.  There are usually special comfy couches set up for the speakers and the conference staff really treat you very nice, taking care of you every step of the way.   In fact, there is an entire very nice culture around how guest speakers are treated in Thailand.   Often, they pin flowers on the VIP speakers and take your photos like you are a star.    Very nice culture.

I absolutely look forward to speaking on event processing or CEP at a future venue and meeting everyone face-to-face instead of over the net.  My sincere and deepest apologies for not attending either the Gartner or the EPTS event this year.   

PS:  If you take up a collection and send me a RT business class air ticket, I might change my mind

Buying a lemon is always a bad thing – but when you pay $1 billion for it?! Back in 2005, Google bought a 5% stake in AOL for $1 billion and now is calling that investment “impaired”. That’s one way of putting it, so it’s a good thing Google has money to burn.

At LinuxWorld this week, Bob Sutor, VP of open source and standards at IBM, said that the next 10 years is “do or die” for open source software designed for specific industries. 10 years? That’s like 70 years in open source development time.

And finally…8/8/08…the Olympics are here! Network administrators around the world, except for Terry Childs, will be eyeing office network bandwidth closely as people go online to watch streaming video of the games. NBC and Microsoft will offer 2,200 hours of live video coverage with up to 20 simultaneous live streams of different events. Plus NBCOlympics.com will offer 3,000 hours of on-demand video content. The time difference means that much of the primetime events will be broadcast while the Western hemisphere is supposed to be hard at work. Me – I’m just glad it’s the weekend, and I can get the Olympics fix I’ve been waiting years for.
