Hi, although the same driving concepts are used, and as announced on the project page, there is currently no backward compatibility between versions of S4.
Generally, you have the following correspondence: - processEvent() -> onEvent() - output() -> <downstream Stream field>.put() To start, please look at the relevant information on the documentation: http://incubator.apache.org/s4/doc/0.6.0/ Hope this helps, Matthieu On Jul 22, 2013, at 16:45 , kiran gvr <gvrkir...@gmail.com> wrote: > Hi, > > I am very new to S4.
