Hi Srinath, The idea with doing parallel things using Storm is a good one, but I hope you still consider optimizations for improving performance on a single node as well, i.e. vertical scalability? I'm pretty sure that Siddhi could be improved to perform 5-10 times faster on a single node if

Hi, I've started playing with WSO2 CEP recently and after some experiments with it I collected a few questions, which I cannot answer by reading the docs.   Hopefully I'll have them answered by posting them on this list. First of all, some background information. I have some previous experience
