   Here it came down to the abstraction we did come up with didn't do very much; most of the value was in the example. In the way it was designed, we asked the user to implement the conversion of one batch of rows to one RecordBatch, and the API took care of the rest. But in our example, most of the logic was *within* that single batch conversion example implementation. It's possible with another pass we could come up a worthwhile API; perhaps if the user-implemented hooks were narrower in scope.
