There have been many projects and companies that have done something similar over the years. I had too, a few years ago - www. S4 is API driven read - more work and lacks some usability features - currently. But the distributed feature is the most appealing. To compare classify S4 as a complex event processing solution is inaccurate.

S4 is missing a number of key components required to be classified as such. Those components are 1 time or length based sliding windows, 2 pattern matching, 3 continuous query, and 4 a language specifically incorporating these aspects. I don't know how to best characterize S4, but it's certainly not CEP and bears very little resemblance to products from either Oracle or StreamBase. Is it possible to build a full-fledged CEP engine on top of S4 by adding the missing components.

What i'm thinking is to develop a set of generic PEs to support these components, then S4 would appeal as a core of a CEP engine. Like Print Bookmarks. Nov 23, 2 min read by Tim Cull.
