Alexandre Alves wrote an interesting article on CEP extensions for Logic Programming (see http://adcalves.wordpress.com/2009/10/30/logic-programming-lp-extensions-for-cep/) in which he mentions the use of Rete-based rules engines. I gave a presentation at a conference last week (October Rules Fest 2009) on the differences and similarities between various event stream processing (ESP) approaches and the Rete algorithm. I had a slide that is not very different in intent to Alexandre’s post. I also touched on performance issues, which is something he talks about briefly. I don’t know of any solid, well thought out, comparative benchmarking between any of the major ESP and CEP-enabled Rete engines, so I can only hazard informed guesses with regard to likely performance issues. I thought it would be useful to summarise some of my thinking in this area.
