Ruby Complex Event Processing

Question

Is there an open-source complex event processing (CEP) engine for ruby?

I'm looking specifically for something that offers stateful analysis, not just rules-engine-style antecedent-predicate productions.

You could try something like rulecore which is language independent. It seems to use webservices and xml.

It's possible to make use of the Java based Esper CEP by using JRuby. This blog post gives a quick, but clear, run through with a basic example.

I haven't been following the CEP scene too closely (I worked with Cayuga from Cornell University, now open source, and Esper around 2006-2007), but I haven't heard of one yet. Most of them appear to be in .NET, Java, and C/C++. There are some event-related libraries for Ruby, but none seem to be anywhere near the capabilities of CEP engines such as Esper or StreamBase.

Most CEP engines are servers that you can talk to in various language independent ways. For example delivering events using TCP/IP, JMS, http or other protocols.
