Hi Matthieu, Sorry for the late response.
Let me explain briefly what i am looking for as part of pattern matching: Today on S4, if i want to build an application like tweeter trend analysis, i need to write my logic as part of processing elements. I need to know which processing elements are stateless, which are stateful. I needs to carefully design my events and their keys to be able to run the processing elements parallel in a distributed environment. That's too technical ! What i am looking for is a simple DSL where i can specify the application logic instead of bothering about low level details. Architecturally i would expect this abstraction layer to be built on top of the current S4 layer. When such DSL models are deployed, the S4 framework should take care of generating the required processing elements in the best possible way so that the logic can be truely executed in parallel in a distributed environment. Hope i am clear. If the initial ideas sounds interesting to the community, we can discuss in detail.

Can you describe a bit more what you are looking for? Thanks, Matthieu On Apr 29, 2013, at 07:14 , Siddharth wrote: Hi - Can somebody throw some light on the short term & mid term roadmap for S4 ? I am interested in knowing whether features like pattern matching is in plan and if yes when are they coming ? Thanks, Siddharth
