Hi, During development of some new processors, I have been looking closely at standard processors to understand best practices. The Developer Guide suggests that one should call session "commit()" upon completion of onTrigger() session processing, which makes sense. However, I notice in a number of standard processors that commit() is not called at all; e.g., see SplitText processor as an example of this. Session transfer() gets called but no commit() calls.
So my question is the commit() call necessary, or are sessions being auto-committed if not rolled back? Is there some penalty to calling session commit() vs. just calling transfer. Sorry for so many questions, but without a Nifi API reference guide, this seems like the fastest way to understand what's intended by the framework. Thanks Rick
