### Describe the subtask Complete and document the five-family compatibility contract for OceanBase CE 4.2.1 in MySQL mode. **Compatibility outcomes** - **Nanosecond timestamps:** Reject precision above 6. - **Variant:** Reject because OceanBase JSON is a narrower contract. - **Unknown/Null:** Reject. - **Geometry:** Reject because current reload loses CRS and SRID. - **Geography:** Reject because OceanBase has no faithful geography 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** Reproduce all five creates against Docker OceanBase and verify each rejects and leaves no table. Cover converter, SQL-generation, module, and formatting checks. **Documentation** `docs/jdbc-oceanbase-catalog.md` ### Parent issue #12056 -- This is an automated message from the Apache Git Service.
