bharos opened a new pull request, #11415:
URL: https://github.com/apache/gravitino/pull/11415
### What changes were proposed in this pull request?
Populate `AuditInfo` (creator and create time) when loading Iceberg tables
via
`IcebergTable.fromIcebergTable()`, instead of hardcoding `AuditInfo.EMPTY`.
- Extract the `owner` table property as the `creator`
- Use `lastUpdatedMillis` from Iceberg `TableMetadata` as the `createTime`
### Why are the changes needed?
When tables are created or updated outside the Gravitino Web UI (e.g., via
Iceberg REST Catalog, Spark, or other Iceberg clients), the "Created by" /
"Updated by" user and timestamp fields are not populated in Gravitino's
metadata
UI. This is because `IcebergTable.fromIcebergTable()` discards the available
audit information by using `AuditInfo.EMPTY`.
Fix: #7833
### Does this PR introduce _any_ user-facing change?
Yes. Tables loaded from Iceberg catalogs will now show the creator (from the
`owner` table property) and creation timestamp in the Gravitino Web UI and
API
responses, where previously these fields were empty.
### How was this patch tested?
Added two unit tests in `TestIcebergTable`:
- `testFromIcebergTablePopulatesAuditInfoWithOwner` — verifies creator and
createTime are populated when the `owner` property is set
- `testFromIcebergTableWithoutOwnerProperty` — verifies no regression when
`owner` is absent (creator is null, createTime is still set)
All existing `TestIcebergTable` tests continue to pass.
