Hi Srinath,
Maybe my explanation was not that good.
As said, we are interested mainly in the CEP side, but at the same
time, it could be a great oportunity to get to know better WSO2 platform
and use other components too.
We dont want to change the way the "events" are managed internally,
but to provide a "bridge" to comunicate WSO2 with "external world", but
in both directions, that is, be able to inject events but also to
"produce" events in Kafka format.
In an ideal world, Kafka events would be injected into WSO2,
transformed in whatever internal format you have, get filtered, go
through business rules, go to CEP, produce its own events and get them
outside again in kafka format. If in the middle they raise a trigger or
are stored in Cassandra or whatever, is not our goal.
Also, th eproject is not that urgent, thus if you say you need to
sovle first an specific issue but once there the best way would be to
work with XYZ, thats is ok
We are just trying to think in advance before doing the real coding
and your info on CEP is just very interesting, specially the fact you do
horizontal scalability right away while Esper requires a "proprietary"
extension
We were thinking about using Twitter's Storm too for some of the
"routing / filtering" stuff (no CEP, I'm aware of that) but seems WSO2
could fit all that too, so its worth a try

Hi Jaime,
CEP Server has something called brokers. That is one way to do this.
You can write a Kafka based broker, and inject events to CEP.
But that works only with CEP, and to support other part of the
platform (e.g. send it to ESB for mediation, service invocation etc),
you will have to write a Axis2 transport.
Currently we are working to make Axis2 transport work for both cases,
but that is in the trunk. It may be easier to start with a broker as
then you do not have to worry about converting to XML (there is a way
to work it without converting to XML, but bit too complex yet, which
we are fixing now).

Hi all,
We would like to add Apache Kafka support to the already long
list of supported protocols of WSO2 in order to be able to exploit
CEP capabilities
Were would be the right place to do so in order to, not only get
Shiddi CEP capabilities but also be able to use other elements of
WSO2 and of course make our contribution worthwhile and
interesting to others
BTW, I have been unable to find any reference to such project.
Nobody has considered this alternative in the past?
