nevzheng opened a new pull request, #12082: URL: https://github.com/apache/gravitino/pull/12082
### What changes were proposed in this pull request? Define and document MySQL compatibility for the five Gravitino V3-native type families. Nanosecond timestamps above MySQL's faithful precision, Variant, Unknown/Null, Geometry, and Geography are rejected before DDL. Existing timestamp precision 6 and below remains unchanged. ### Why are the changes needed? MySQL cannot recover the full identity and parameters of these V3-native families through the connector's current schema contract. Explicit rejection prevents silent narrowing and partial table creation. Fix: #12066 Related: #12056 Shared JDBC preflight: #12065 Shared JDBC preflight PR: #12081 ### Does this PR introduce _any_ user-facing change? Yes. Unsupported V3-native schemas fail before DDL, while existing supported timestamp behavior is preserved. ### How was this patch tested? - Added exact converter-message coverage. - Covered Docker create rejection and no-table behavior. - Retained precision-6 timestamp controls. - Updated `docs/jdbc-mysql-catalog.md`. -- This is an automated message from the Apache Git Service.
