xylaaaaa opened a new pull request, #63783:
URL: https://github.com/apache/doris/pull/63783
## Proposed changes
- Add Snowflake as a JDBC catalog database type, including identifier
quoting, LIMIT query generation, scan table type propagation, and
Snowflake-specific type mapping.
- Add Snowflake JDBC catalog connection validation that requires dedicated
`snowflake.database` and `snowflake.warehouse` properties, and rejects `db` /
`database` / `warehouse` in `jdbc_url`.
- Add Snowflake OAuth token handling for FE connection tests and BE JDBC
scanner/writer Hikari data sources.
## Notes
- Snowflake maps as: Doris catalog -> Snowflake account + fixed database,
Doris database -> Snowflake schema, Doris table -> Snowflake table.
- No regression-test suite is added because real Snowflake validation
requires external account credentials, driver jar, and network access. Coverage
is added through focused FE/BE unit tests.
## Testing
- `mvn -Dmaven.build.cache.enabled=false -pl fe-connector/fe-connector-jdbc
-am
-Dtest=JdbcConnectorProviderValidateTest,JdbcDorisConnectorTest,JdbcDbTypeTest,JdbcIdentifierQuoterTest,JdbcQueryBuilderTest,JdbcScanRangeAndPropertiesTest,JdbcUrlNormalizerSnowflakeTest,JdbcSnowflakeConnectorClientTest
-DfailIfNoTests=false test`
- Tests run: 133, Failures: 0, Errors: 0, Skipped: 0
- `mvn -Dmaven.build.cache.enabled=false -pl be-java-extensions/jdbc-scanner
-am -Dtest=SnowflakeJdbcAuthUtilsTest -DfailIfNoTests=false test`
- Tests run: 3, Failures: 0, Errors: 0, Skipped: 0
