### Describe the subtask Complete and document the five-family compatibility contract for Hologres. **Compatibility outcomes** - **Nanosecond timestamps:** Reject because Hologres precision limits are below 9. - **Variant:** Reject. - **Unknown/Null:** Reject. - **Geometry:** Reject because current spatial JDBC reload loses subtype, SRID, and CRS semantics. - **Geography:** Reject because current spatial JDBC reload loses subtype, SRID, CRS, and edge semantics. **Acceptance** - Reproduce all five families through the connector's public create/conversion path and its alter/load paths where supported. - A supported mapping must round-trip without losing type identity or parameters. - An unsupported mapping must return `IllegalArgumentException` before external metadata mutation; no fallback to a narrower or opaque type is allowed. - Cover nested types where the connector supports complex columns. - Add focused converter/operation tests and an integration or no-side-effect test appropriate to the connector. - Update the connector documentation with a five-family compatibility matrix and rejection rationale. - Keep implementation commits atomic by connector and type family. **Connector-specific verification** Cover converter, operation, and no-side-effect paths. Run the module tests and keep cloud integration verification credential-gated with its required environment documented. **Documentation** `docs/jdbc-hologres-catalog.md` ### Parent issue #12056 -- This is an automated message from the Apache Git Service.
