A Log-Structured Storage Boom!

Jack Rusher - 12.22.2009

We appear to be in the midst of a log-structured storage boom. It's always gratifying to see smart people converge with your work, and that's exactly what's been happening with since we implemented a log store underneath the Aleri Platform.

Many Cores, Concurrency and CEP

Jack Rusher - 12.01.2009

Tim Bray has been thinking hard about concurrency lately. He predicts that more and more machines will be built with large numbers of relatively low-speed CPUs, and that programming these machines is going to be one of the big challenges of the next 10-15 years.

Aspects of Time

Robert Hagmann - 09.10.2009

Various CEP systems handle “time” differently. This was surprising, in some ways. After all time is time, right? So how could it be very different? Well there were a lot of differences. Now I’m not saying some approaches are right or some are wrong, but rather I think that the differences are interesting. So here are some of the aspects I think are interesting.

World's Fastest Stock Exchange?

Jack Rusher - 09.03.2009

Computerworld recently printed a piece on the "World's Fastest Stock Exchange" (the Deutsche Borse), which runs on a pile of commodity Linux machines. I'm temperamentally hostile to superlatives, and find it hard to imagine that all the major exchanges agreed to take part in a public benchmark, but a million trades per second is a nice data rate.

MongoDB and Real-Time Analytics

Jack Rusher - 07.09.2009

There's been some talk in the community regarding the use of grid computing for CEP. This recent effort to track real time performance metrics for a website using an application coded on top of MongoDB shows one possible application for that technology.

Hard coding apps vs CEP platforms

Jeff Wootton - 07.07.2009

We often talk to programmers who have not used commercial CEP technology before who question why they wouldn't just implement event processing themselves directly in their application - i.e. build their app in Java or C++ or C#, and hard code the event processing logic. I've commented on this topic before, but I just read a post by Opher on his blog that I thought summed it up rather nicely.
