dramaticlly opened a new issue, #7560:
URL: https://github.com/apache/iceberg/issues/7560
### Feature Request / Improvement
It would be nice to provide last updated timestamp in partition metadata
table to see if there's any change applied to given partition.
According to @szehon-ho , today this can be done via following SQL
```sql
SELECT
e.data_file.partition,
MAX(s.committed_at) AS last_modified_time
FROM db.table.snapshots s
JOIN db.table.entries e
WHERE s.snapshot_id = e.snapshot_id
GROUP BY by e.data_file.partition
```
which join the entries table and snapshot together to derive the max
snapshot commit timestamp group by partition, however this feature request
attempt to provide native support in partition metadata table
