This creates an `OverwriteByExpression` with a partition filter predicate (e.g., `p <=> 1`), which requires the WriteBuilder to implement `SupportsOverwriteV2` and the table to declare `OVERWRITE_BY_FILTER` capability. + +Currently, FileTable's WriteBuilder only implements `SupportsTruncate` (full table overwrite) and `SupportsDynamicOverwrite`, so static partition overwrite fails with: + +``` +[UNSUPPORTED_OVERWRITE.TABLE] Can't overwrite the target table ... by a filter other than "true". +``` + +#### Proposed Changes + +1. **FileTable.createFileWriteBuilder**: Add `SupportsOverwriteV2` to the WriteBuilder. Implement `canOverwrite()` to accept partition-column equality predicates, and `overwrite()` to store the predicates for use at write time. + +2. **FileWrite.toBatch()**: Extend overwrite logic to support partition-level directory deletion. Parse the stored predicates to extract the static partition spec, compute the matching partition path (e.g., `/table/p=1`), and delete only that subdirectory before writing — matching V1's `InsertIntoHadoopFsRelationCommand.deleteMatchingPartitions` behavior. + +3. **FileTable.CAPABILITIES**: Add `OVERWRITE_BY_FILTER`. + +4. **Format Write classes**: Plumb the overwrite predicates parameter through all 6 format Write classes (Parquet, ORC, CSV, JSON, Text, Avro), following the same pattern as `bucketSpec` in SPARK-56177. + +#### Why + +This is a prerequisite for SPARK-56304 (V2 ifPartitionNotExists for INSERT INTO), and completes the V2 static partition overwrite support that was missing after removing the file source V2 gate (SPARK-56170). + +#### Scope + +~4-6 source files changed, ~100-150 lines added.

Row count injected into FileScan via `FileTable.NUM_ROWS_KEY` option. Table size auto-updated after every V2 file write. + +4. **syncNewPartitionsToCatalog** — After V2 file writes, auto-discovers new partitions on disk and registers them in catalog metastore (best-effort with warning logging). + +5. **Streaming fallback** — FileTable lacks MICRO_BATCH_READ/STREAMING_WRITE. Streaming reads fall back to V1 via FindDataSourceTable. Estimated 700-1200 LOC to implement V2-native streaming (SPARK-56232/56233). + +6. **Bucketed writes** — Uses DynamicPartitionDataConcurrentWriter because V2's RequiresDistributionAndOrdering cannot express hash-based ordering needed by DynamicPartitionDataSingleWriter. Bucket pruning/join optimization (read path) deferred to SPARK-56231. + +7. **MSCK REPAIR TABLE** — RepairTableExec scans filesystem partitions via FileTable.listPartitionIdentifiers(), diffs with catalog, and adds/drops as needed.
