Hi all, I propose the following updates to our partition stats spec in V3:
- Modify `position_delete_record_count` to include a sum of position deletes across position delete files and DVs - Keep `position_delete_file_count` to represent the number of position delete files (ignoring DVs) - Add `dv_count` to represent the number of DVs - Make delete counts required to avoid ambiguity w.r.t NULL vs unknown. Here is the PR with the spec update: https://github.com/apache/iceberg/pull/12098 - Anton
