   I'm not sure what you mean by force V2 sources and try the Parquet version 
again. I was comparing both the v1 and v2 memory usage and the v2 path using 
iceberg consumes significantly more memory. 
   
   Is there a v2 equivalent to 
   
   ```java
   sparkSession.read().load(paths)
   ```
   
   
   Speaking of should be handled on the last next() call.  I don't see that in 
my experimental changes which did reduce memory usage.
