New Open Source CEP Platform
I have now added ActiveInsight into the vendors list.
So now there’s five open source projects to choose from when you something really cheap* (= zero dollars in license fee). I have not yet looked into their product in detail, but their web page says all the right things, so it seems that they understand this CEP thing at least on presentation level. If someone have used their product, please share your expericeces. What would be most interesting to learn is how they compare to the other open source products (Pion, Esper, Drools Fusion and IEP) .
It’s a good start for the next year to see another open source product in the CEP space, I hope there will be a couple of more in 2010. At least I heard rumours about a major fork to Esper that is being developed with a rather large number of developers on the project.
2010 is soon upon us. Maybe it’s time to be a Gartner wannabe for a while and do a bunch of predictions on CEP… Maybe in next post, so stay tuned
* If you still prefer to pay for your CEP software, there’s Progress Apama, Tibco Business Events, IBM BusinessEvents, Rulecore, Aleri, StreamBase to choose from.
I am wondering what Esper fork you are talking about, what would motivate it and ultimately for what benefits for the end users. Esper is open source under GPL license, and as far as I know the team has never rejected contributions or contributors.
ETALIS is an open source CEP engine with a corresponding rule-based language. Could you please add it to the vendor list that you have created? I can provide you with a short system description about ETALIS: http://code.google.com/p/etalis
