nevzheng opened a new pull request, #12078: URL: https://github.com/apache/gravitino/pull/12078
### What changes were proposed in this pull request? Define and document Paimon compatibility for the five Gravitino V3-native type families. | Type family | Outcome | | --- | --- | | Nanosecond timestamps | Round-trip exact precision-9 timestamps. | | Variant | Round-trip through Paimon's native Variant type. | | Unknown/Null | Reject before mutation. | | Geometry | Reject because CRS metadata cannot be preserved. | | Geography | Reject because CRS and edge-algorithm metadata cannot be preserved. | ### Why are the changes needed? Paimon can represent two V3-native families faithfully, but the other families must not be silently narrowed or serialized opaquely. Fix: #12062 Related: #12056 ### Does this PR introduce _any_ user-facing change? Yes. Precision-9 timestamps and Variant gain exact mappings; unsupported Unknown and spatial schemas fail before mutation. ### How was this patch tested? - Added real filesystem catalog create/load round-trip coverage. - Covered rejected create and mixed-alter no-side-effect behavior. - Covered focused and full module paths. - Updated `docs/lakehouse-paimon-catalog.md`. -- This is an automated message from the Apache Git Service.
