Francois Saint-Jacques commented on ARROW-7808:
-----------------------------------------------

I concur with [~bkietz] here, prefer a high-level approach, e.g. it should 
start with the factory, dataset and getting the result of a scan, then you can 
expose more and more of the inner classes, instead of 1-1 with all the classes.

Also note that a JNI bridge means one more maintenance burden; we already did a 
bunch of renames and it was cumbersome to do it for each "native" binding too, 
e.g. DataSource is now called Source.
