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
Hazelcast solution let you have large windows, but it is much much slower
than the single node. So it is not good choice for scaling.
We are currently work on Siddhi and Storm integration (Due in Q3 this
year), where you can annotate queries with how to distribute it and we will
multiple Siddhi
Hi,
Could someone answer a few questions asked in my last message (about modeling a
huge number of sensors)? I would be very interested in answers.
Thanks a lot,

For example, can I define (tens of) thousands of queries using the same
(or multiple) instance of SiddhiManager? Would it make processing much
First of all, thank you very much for your explanations and
clarifications! It is very interesting and useful!
Let me ask a few more questions and provide a few comments.

One more thing:
It could be very, very useful, if Siddhi/WSO2 CEP would have a
description/document like this:
http://esper.codehaus.org/tutorials/solution_patterns/solution_patterns.html
This document covers many generic CEP use-cases and then shows how they can be
solved using Esper.

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
