Mark Tsimelzon, President & CTO, Coral8 replies to CEP Product Complexity at Coral8 with More on CEP and Complexity.
In Mark’s reply he gently reminds us that the Coral8 Engine is a developer’s tool, not a business users tool. Mark also tacitly reminds us that his customers are a bit smarter than our development team at Techrotech. Perhaps that is why we can never get our SOA project off the ground!
Mark’s customers can learn a new concept in a single day; however, our developers need a full week to learn the same thing. Making matters more difficult, our CIO at Techrotech, Jerry Fleck is clueless according to the marketing analysts. Jerry has not yet figured out SOA; so concepts like windows, joins, design patterns, causal tracking, messaging layers, adapters, CCL, and persistance will cause Jerry to fall Off the Grid.
It took us years to get rid of most of our legacy C programmers, bring in a bunch of Java gurus, and at the same time, correct our stock option backdating “clerical errors”. Maybe we should now replace our worthless legal and HR departments with a CEP Engine?

In What makes a Coral8 Expert?, Coral8 CTO Mark Tsimelzon outlines nearly 60 subject areas that a customer must master to become a Coral8 expert.
While this complexity is impressive, it tends to demonstrate why CEP is, today, more hype than reality.
I can hear the team at Techrotech in my mind, “Yea! Greg purchased Coral8 for our CEP solutions yesterday! Holy Cow!! Let’s go out and learn 60 topics in depth so we can become experts in using and deploying Coral8!”
So, let’s say you are intelligent and can master a subject in a single weeks time (if you have nothing else to do), so you can become a Coral8 expert in only one year if you don’t have a day job!!
I don’t know about you, but the way Mark describes their product, Coral8 sounds more like a lab tool for the engineering department of Caltech or Stanford than a tool for everyday business users. Mark concludes his post;
Not too scary, is it? – Mark Tsimelzon, President & CTO, Coral8
Hmmmm. I think I’ll ask the software team at Techrotech to write some event processing applications in C since we have a strong team of C programmers coming off another project next week…. then again, I heard some Java programmers will be free in two weeks ….

Like the predictable ebb and flow of ocean tides, we see the rise, falling and passing away of lively debates about event processing languages (EPLs). For example, you might recall that Louis Lovas, Progress Apama, did an excellent job in his post, Bending the Nail, where he described why SQL or Extended SQL is not the optimal EPL for event processing.
A few of us in the “SQL is not necessarily the best EPL” choir started singing with Louis which motivated a counter voice the choir with the post, Fair and unfair criticism of an SQL EP approach only to have the same author counter that post with, One down side to an SQL EP approach.
Many technologists, including some of my team members at Techrotech, enjoy focusing on linear event processing problems with strict determinism, for example, processing a stream of market data and looking for opportunities to enter or exit the market (algo trading). These same technologists tend champion event processing problems that are basic transformations of simple streams of time-series data.
Many of the so-called CEP cybertrading examples (I would argue that these are simple event processing, not complex event processing examples) are not rooted in event processing scenarios that require looking for causal linkages between seemingly unrelated events; for example, debugging complex distributed systems or detecting fraud over long periods of time where sliding time windows on continuous streaming data are only a part of the solution in the uncertain world of cloudy event-causality relationships.
Time-series analysis with strict determinism are interesting, but I would not go so far at to call this processing ”complex event processing” relative to the myriad challenging complex problems in the real-world.
