goutamadwant opened a new pull request, #11794: URL: https://github.com/apache/gravitino/pull/11794
### What changes were proposed in this pull request? This PR adds a generic read-only JDBC catalog provider named `jdbc-generic`. The new catalog uses standard `DatabaseMetaData` calls to discover schemas, tables, views, columns, primary keys, and unique indexes. It also adds conservative JDBC type mapping for common standard types, with unknown or vendor-specific types preserved as Gravitino `ExternalType`. It includes metadata filter options for catalog pattern, schema pattern, table types, included schemas, and excluded schemas, and wires the new module into the Gradle settings and catalog distribution packaging. ### Why are the changes needed? Fix: #11453 This provides a baseline JDBC metadata catalog for databases that do not yet have a dedicated Gravitino JDBC catalog implementation. ### Does this PR introduce any user-facing change? Yes. Users can configure the new `jdbc-generic` catalog for read-only metadata discovery through JDBC. Write and DDL operations are intentionally unsupported in this catalog. ### How was this patch tested? - `./gradlew :catalogs:catalog-jdbc-generic:spotlessApply -PskipITs` - `./gradlew :catalogs:catalog-jdbc-generic:test -PskipITs` - `./gradlew :catalogs:catalog-jdbc-generic:build -PskipITs` - `./gradlew :catalogs:catalog-jdbc-generic:copyLibAndConfig -PskipITs` -- This is an automated message from the Apache Git Service.
