   I want to, and I'm open to ideas. To re-create the problem you need a 
parquet file which has a full row group over 2GB in size followed by some more 
data, which translates to over 13GB+ of memory used. My concern is whether such 
a test would blow the constraints during CI or put an unreasonable memory 
burden on anyone wanting to build/test the project. What are reasonable limits 
there?
   
   I will add that no tests have found a regression with this change.
