   To solve this issue in aggregate, we need 
https://github.com/apache/datafusion/issues/7065
   
   However (at least in the near term), we can't guarantee to prevent similar 
issue in other operators that buffer and concat input batches: `BianryArray` 
will overflow if it's > 2GB, there are other places like hash join might 
trigger the similar bug.
   
   I think we could let it return a better error message, and suggest user to 
use `LargeBinary` type instead.
