[GitHub] [iceberg] szehon-ho commented on pull request #2240: Auto promote sorted column metrics to full

URL: https://github.com/apache/iceberg/pull/2240#issuecomment-779714521


   PR Background:
   
   A suggestion from @aokolnychyi , we find that users do not tend to fine-tune column metrics.  The default truncate(16) does not do much for certain sortable types, and reduces benefits of predicate pruning.  Cost of storing full metrics should be small as number of sorted columns will be generally small.
