The Mollyzine - Phillip Molly Malone’s Blog

Ever had a large amount of information about events coming in from a source that your really only interested in bits and pieces of. Not only that, but you just as interested to know if event B happens with in 2 minutes of event A because then you want to do something. The your probably interested in Event Stream Processing (ESP). Its a programing model that where you are just as interested in the fact an event occurred as you are with what the event is. He is a better explanation:

Event Stream Processing (ESP) is a new form of distributed computing that enables organizations to monitor data streams, quickly analyze the streaming data for patterns of significance, and then respond with actionable results. With ESP (sometimes called Complex Event Processing or CEP) organizations can monitor their performance against Key Performance Indicators (KPIs), pursue new opportunities, and identify, if not completely prevent, potential threats. As an implementation of event-driven architectures (EDAs), event processing systems are designed to deliver real-time data processing performance by eliminating the latencies inherent in traditional computing architectures.

This model is extremely Popular in the Stock trading field (looking at the stock ticker and seeing trends that result in you doing a trade) and RFID (image having Hundreds, Thousands or billions of RFID reads coming in and working out what is important and what isn’t) but any high event system could work (I always wonder if an F1 team couldn’t use this! E.G. If <something to do with the Engine> happens and then within other event happens, could be a problem in the … I mean, they have a ton of information coming from the cars every second of a race, sounds like an interesting use of Event Stream Technology to me).

Sound interesting? You live in Melbourne (or Victoria for that matter)? The talk below might be for you:

John Bates, Vice President of Products, Event Stream Processing from the Progress Apama division is in Melbourne during October and is available to present to the user group. ESP and BAM are growing requirements in a range of modern applications. The volume and frequency of data updates (events) more than doubles every year. The need to monitor data for complex Key Performance Indicators (KPIs) in order to detect when certain business metrics exceed certain critical levels is becoming increasingly real–time (ESP) rather than end–of–day or end–of–month.

Hope to see you there. Do let the organizers know if your interested.
