I'm surprised to see that we report the total data file size back to Spark. At Netflix, we switched over to reporting row size estimate * number of rows a long time ago to fix broadcast join memory problems. Spark should ignore the size on disk and use the row size * num rows, but if Spark doesn't do that then I think Iceberg should report that as the size instead. -- This is an automated message from the Apache Git Service.
