## Summary P1 batch A — close out scan-node SPI consolidation while keeping migration-period fallbacks in place. Three surgical changes route `PluginDrivenExternalTable` first in the nereids translator hot paths so already-migrated SPI connectors (JDBC, ES) take the SPI route, while the existing `instanceof XExternalTable` chains remain as fallbacks for connectors still pending migration (P3–P7). - **T3** — `PhysicalPlanTranslator.visitPhysicalFileScan`: move the existing `PluginDrivenExternalTable` branch from position 8 to position 1; the 7 connector-specific branches (HMS / Iceberg / Paimon / Trino / MaxCompute / LakeSoul / RemoteDoris) stay in place as migration-period fallbacks - **T4** — `PhysicalPlanTranslator.visitPhysicalHudiScan`: add a `PluginDrivenExternalTable` branch routed to `PluginDrivenScanNode.create(...)`, threading `tableSnapshot` + `scanParams` through `FileQueryScanNode` setters; `incrementalRelation` flagged as a P3 Hudi SPI extension TODO. The new branch is unreachable today (`PhysicalHudiScan` is only built for `HMSExternalTable + DLAType.HUDI`), so this is groundwork for P3 with zero current-day runtime impact - **T5** — `LogicalFileScan`: in `computeOutput()`, add a `PluginDrivenExternalTable` branch calling new helper `computePluginDrivenOutput()` — same shape as `computeIcebergOutput`, using `getFullSchema()` + virtualColumns; in `supportPruneNestedColumn()`, add an explicit `PluginDrivenExternalTable → false` branch. Both behaviorally equivalent for JDBC/ES today since they have no hidden cols and no virtualColumns P1 batch B (T1 — delete 13 legacy `Jdbc*Client` + `JdbcFieldSchema`) is deferred to P8 because the 3 fe-core callers — `PostgresResourceValidator`, `StreamingJobUtils`, `CdcStreamTableValuedFunction` — are live CDC streaming code that requires SPI extension for `getPrimaryKeys` / `getColumnsFromJdbc` / `listTables`, which is out of P1 surgical scope. Background and tracking docs live in `plan-doc/` (Master Plan §3.2 P1, tasks/P1-scan-node-cleanup.md, decisions log). ## Test plan - [x] `mvn -pl fe-core -am compile -Dmaven.build.cache.enabled=false` → BUILD SUCCESS - [x] `mvn -pl fe-core checkstyle:check` → 0 violations - [x] JDBC + ES regression-test passing — baseline established in P0 / PR #63582 - [ ] PR CI green on this PR - [ ] Manual scan-node smoke for an SPI connector — JDBC `SELECT *` should fall into the new `PluginDrivenExternalTable` branch first 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
