What's Going On? : Complex Event Processing w/ Esper

How well do you understand the dynamics of your applications? In our systems, we detect when simple things happen. Customers log in, people buy things, a stock is sold at a particular price, inventory shifts locations… all of these events mean little things, but what about the larger picture? Complex events are particular patterns of simpler events that suggest something deeper is happening. Do you know how you'd discover these bigger picture occurrences? Come hear how the Esper open source software represents a new class of complex event processing (CEP) frameworks that can be added to even high volume, high transaction systems.

Trying to write software to track event occurrence is difficult to do correctly and almost impossible to do efficiently. The problem is that the higher volume and performance our systems get, the harder it becomes and the more important it is to highlight interesting or unexpected activity that isn't represented simply by a log entry.

Complex Event Processing (CEP) and Event Stream Processing (ESP) systems are emerging as a new strategy for processing and detecting complex sequences of more rudimentary events that could have bigger implications to your production systems. While commercial software is starting to add this behavior, Esper represents one of the most accessible and widely-used frameworks for adding CEP/ESP capabilities to Java applications.
