What Features are missing from Rx that are in CEP Platforms such 开发者_开发百科as NEsper or MS StreamInsight?
CEP Platforms like StreamInsight are an enterprise-grade solution for processing lots of events at high volume and applying pattern-matching algorithms to said events.
There are a lot of domain-specific things applied to events in CEP Platforms, such as event classification (point event, interval event, edge event) that aren't first-class in Rx.
In short, it seems like you could conceivably build a CEP Platform using Rx, but it is not useful as a CEP Platform on its own. The analogy I would draw is Rx is to CEP as WCF is to nServiceBus. nServiceBus is a communication platform, but it has much more domain-specificity than WCF does (where domain is enterprise-grade messaging, in this case).
