+### Title
+
+[SQL] Support static partition overwrite for V2 file tables (SupportsOverwriteV2)
+
+### Description
+
+#### Background
+
+After SPARK-56171 removed the V2 file write gate, `INSERT OVERWRITE TABLE t PARTITION(p=1) SELECT ...` on file tables goes through the V2 write path. 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. Low risk — follows existing V1 patterns and V2 SupportsOverwriteV2 contract.

+
+## Key Design Decisions
+
+1. **V2-native partition DDL** — No V1 fallbacks in ResolveSessionCatalog for partition commands. FileTable's SupportsPartitionManagement handles ADD/DROP/SHOW/TRUNCATE/RENAME PARTITION natively via DataSourceV2Strategy.
+
+2. **saveAsTable Overwrite** — Uses `OverwriteByExpression(Literal(true))` for existing file tables instead of `ReplaceTableAsSelect` (which requires StagingTableCatalog). Creates table via `CreateTableAsSelect` when table doesn't exist.
+
+3. **Stats propagation** — ANALYZE TABLE stores stats via `TableCatalog.alterTable(TableChange.setProperty(...))`. 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. Also handles ALTER TABLE RECOVER PARTITIONS (add-only, no drop).
+
+## Investigation Notes
+
+### SPARK-56231: Bucket pruning/join for V2 read path
+
+**Implementation plan (two phases):**
+
+**Phase A — Bucket pruning (filter files by bucket ID):**
+1. Add `bucketSpec: Option[BucketSpec]` to `FileScan` trait
+2. Expose `bucketSpec` accessor on `FileTable`
+3. Thread `bucketSpec` through `FileScanBuilder` to all 6 format Scan classes
+4. Extract `getExpressionBuckets`/`genBucketSet` from `FileSourceStrategy` to `BucketingUtils` (shared utility)
+5. Add `bucketedScan`, `disableBucketedScan`, `optionalBucketSet` fields to `FileScan`
+6. Implement bucket pruning in `FileScan.partitions` — filter files by bucket ID, group by bucket
+
+**Phase B — Bucket join (HashPartitioning + optimizer rules):**
+7. Override `outputPartitioning` in `BatchScanExec` to return `HashPartitioning` for bucketed scans
+8. Group files by bucket ID in `FileScan.partitions` (one `FilePartition` per bucket)
+9. Extend `DisableUnnecessaryBucketedScan` to handle `BatchScanExec` with bucketed `FileScan`
+10. Extend `CoalesceBucketsInJoin` to handle V2 bucketed scans
+11. Add `withDisableBucketedScan`/`withNumCoalescedBuckets` methods to `FileScan` + all concrete Scans
+
+**Key files:** FileScan.scala, FileTable.scala, BatchScanExec.scala, BucketingUtils.scala, DisableUnnecessaryBucketedScan.scala, CoalesceBucketsInJoin.scala, + all 6 format ScanBuilder/Scan classes
+
+**Branch:** `SPARK-56231` in worktree `spark-56171-combined`, on top of SPARK-56304. Not started yet.
+
+### SPARK-56230: DEFAULT column values for V2 writes
+- **Gap**: `ResolveColumnDefaultInCommandInputQuery` (catalyst module) handles `InsertIntoStatement` but not V2 write commands (`AppendData`, `OverwriteByExpression`, `OverwritePartitionsDynamic`). Has existing TODO: SPARK-43752.
+- **Decision**: Deferred — catalyst-level change affecting all V2 sources, not file-table-specific.

+### Title
+
+[SPARK-56177][SQL] V2 file bucketing write support
+
+### Description
+
+#### What changes were proposed in this pull request?
+
+Enable bucketed writes for V2 file tables via catalog `BucketSpec`.
+
+Changes:
+- `FileWrite`: add `bucketSpec` field, use `V1WritesUtils.getWriterBucketSpec()` instead of hardcoded `None`
+- `FileTable.createFileWriteBuilder`: extract `catalogTable.bucketSpec` and pass to the write pipeline
+- `FileDataSourceV2.getTable`: use `collect` to skip `BucketTransform` (handled via `catalogTable.bucketSpec`)
+- `FileWriterFactory`: use `DynamicPartitionDataConcurrentWriter` for bucketed writes since V2's `RequiresDistributionAndOrdering` cannot express hash-based ordering
+- All 6 format Write/Table classes (Parquet, ORC, CSV, JSON, Text, Avro) updated with `BucketSpec` parameter
+
+#### Why are the changes needed?
+
+After SPARK-56171 removed the V2 file write gate, `INSERT INTO` a bucketed file table goes through the V2 write path. Without this change, `WriteJobDescription.bucketSpec` is always `None`, so bucketed tables produce non-bucketed files.
+
+#### Does this PR introduce _any_ user-facing change?
+
+No. Bucketed file tables now correctly produce bucketed files via the V2 write path, matching V1 behavior.
+
+#### How was this patch tested?
+
+Added tests in `FileDataSourceV2WriteSuite`:
+- Bucketed write with bucket ID verification via `BucketingUtils.getBucketId`
+- Partitioned + bucketed write with partition directory and bucket ID verification
+- All existing `BucketedWriteWithoutHiveSupportSuite` tests pass (15 total)

+### Title
+
+[SPARK-56178][SQL] MSCK REPAIR TABLE for V2 file tables
+
+### Description
+
+#### What changes were proposed in this pull request?
+
+Implement `RepairTableExec` for V2 file tables to sync filesystem partition directories with the catalog metastore.
+
+Changes:
+- New `RepairTableExec`: scans filesystem partitions via `FileTable.listPartitionIdentifiers()`, compares with catalog, registers missing partitions and drops orphaned entries
+- `DataSourceV2Strategy`: route `RepairTable` and `RecoverPartitions` for `FileTable` to the new V2 exec node (non-FileTable V2 tables still throw)
+
+#### Why are the changes needed?
+
+After SPARK-56175 changed `V2SessionCatalog.loadTable` to return `FileTable` instead of `V1Table`, `MSCK REPAIR TABLE` and `ALTER TABLE RECOVER PARTITIONS` on file tables hit the V2 error path (`repairTableNotSupportedForV2TablesError`). A V2-native implementation is needed.
+
+#### Does this PR introduce _any_ user-facing change?
+
+No. `MSCK REPAIR TABLE` and `ALTER TABLE RECOVER PARTITIONS` continue to work on file tables, now via the V2 path.
+
+#### How was this patch tested?
+
+Added test in `FileDataSourceV2WriteSuite`:
+- Create partitioned table, write data directly to filesystem partition directories, verify catalog has no partitions before repair, run `MSCK REPAIR TABLE`, verify 3 partitions registered in catalog and data is readable

+### Title

+[SPARK-56316][SQL] Support static partition overwrite for V2 file tables
+
+### Description
+
+#### What changes were proposed in this pull request?
+
+Implement `SupportsOverwriteV2` for V2 file tables to support static partition overwrite (`INSERT OVERWRITE TABLE t PARTITION(p=1) SELECT ...`).
+
+Changes:
+- `FileTable.createFileWriteBuilder`: replace `SupportsTruncate` with `SupportsOverwriteV2`, implement `overwrite(predicates)` to store overwrite predicates
+- `FileWrite.toBatch()`: extend overwrite logic to delete only the matching partition directory (ordered by `partitionSchema`) instead of the entire table
+- `FileTable.CAPABILITIES`: add `OVERWRITE_BY_FILTER`
+- All 6 format Write/Table classes: plumb `overwritePredicates` parameter
+
+#### Why are the changes needed?
+
+After SPARK-56171 removed the V2 file write gate, `INSERT OVERWRITE TABLE t PARTITION(p=1) SELECT ...` goes through the V2 path, which creates an `OverwriteByExpression` with a partition filter. This requires `OVERWRITE_BY_FILTER` capability and `SupportsOverwriteV2` on the write builder, neither of which FileTable previously had.
+
+This is also a prerequisite for SPARK-56304 (V2 ifPartitionNotExists for INSERT INTO).
+
+#### Does this PR introduce _any_ user-facing change?
+
+No. Static partition overwrite on file tables now works via the V2 path, matching V1 behavior.
+
+#### How was this patch tested?
+
+Added test in `FileDataSourceV2WriteSuite`:
+- Insert data into two partitions, overwrite one partition with new data, verify only the target partition is replaced while the other remains unchanged

+# SPARK-56231: Bucket Pruning and Bucket Join for V2 File Read Path
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Enable bucket pruning (skip irrelevant bucket files during scan) and bucket join optimization (shuffle-free joins on bucketed V2 file tables) for the V2 file read path, matching V1 FileSourceScanExec behavior.
+
+**Architecture:** Thread `BucketSpec` from `FileTable.catalogTable` through `FileScan` to enable two optimizations: (A) filter files by bucket ID during `FileScan.partitions` to skip unneeded files, and (B) report `HashPartitioning` from `DataSourceV2ScanExecBase.outputPartitioning` so `EnsureRequirements` can avoid shuffles for bucketed joins. Extend `DisableUnnecessaryBucketedScan` and `CoalesceBucketsInJoin` rules to handle `BatchScanExec` with V2 bucketed `FileScan`.
+
+**Tech Stack:** Scala, Apache Spark SQL (catalyst + sql/core), SBT

+
+## Task 1: Add Bucket Fields to FileScan Trait
+
+**Files:**
+- Modify: `sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/v2/FileScan.scala`
+
+- [ ] **Step 1: Add imports and bucket-related fields to FileScan trait**
+
+Add import (use Spark's BitSet, NOT scala.collection.mutable.BitSet):
+```scala
+import org.apache.spark.sql.catalyst.catalog.BucketSpec
+import org.apache.spark.sql.execution.datasources.BucketingUtils
+import org.apache.spark.util.collection.BitSet
+```
+
+Add after the `dataFilters` def (line ~82):
+
+```scala
+/** Optional bucket specification from the catalog table. */
+def bucketSpec: Option[BucketSpec] = None
+
+/** When true, disables bucketed scan. Set by DisableUnnecessaryBucketedScan. */
+def disableBucketedScan: Boolean = false
+
+/** Optional set of bucket IDs to scan (bucket pruning). None = scan all. */
+def optionalBucketSet: Option[BitSet] = None
+
+/** Optional coalesced bucket count. Set by CoalesceBucketsInJoin. */
+def optionalNumCoalescedBuckets: Option[Int] = None
+```
+
+- [ ] **Step 2: Add `bucketedScan` computed property**
+
+Must check `conf.bucketingEnabled` to match V1 behavior. Use case-insensitive column matching:
+
+```scala
+lazy val bucketedScan: Boolean = {
+ conf.bucketingEnabled && bucketSpec.isDefined && !disableBucketedScan && {
+ val spec = bucketSpec.get
+ val resolver = sparkSession.sessionState.conf.resolver
+ val bucketColumns = spec.bucketColumnNames.flatMap(n =>
+ readSchema().fields.find(f => resolver(f.name, n)))
+ bucketColumns.size == spec.bucketColumnNames.size
+ }
+}
+```
+
+- [ ] **Step 3: Add `withDisableBucketedScan` and `withNumCoalescedBuckets` methods**
+
+```scala
+def withDisableBucketedScan(disable: Boolean): FileScan = this
+def withNumCoalescedBuckets(numCoalescedBuckets: Option[Int]): FileScan = this
+```
+
+- [ ] **Step 4: Rewrite `partitions` for bucketed support**
+
+Compute `maxSplitBytes` once before the loop. For bucketed scans, use `Long.MaxValue` to avoid splitting bucket files:
+
+```scala
+protected def partitions: Seq[FilePartition] = {
+ val selectedPartitions = fileIndex.listFiles(partitionFilters, dataFilters)
+ val maxSplitBytes = if (bucketedScan) Long.MaxValue
+ else FilePartition.maxSplitBytes(sparkSession, selectedPartitions)
+ val partitionAttributes = toAttributes(fileIndex.partitionSchema)
+ val attributeMap = partitionAttributes.map(a => normalizeName(a.name) -> a).toMap
+ val readPartitionAttributes = readPartitionSchema.map { readField =>
+ attributeMap.getOrElse(normalizeName(readField.name),
+ throw QueryCompilationErrors.cannotFindPartitionColumnInPartitionSchemaError(
+ readField, fileIndex.partitionSchema))
+ }
+ lazy val partitionValueProject =

+## Task 2: Expose BucketSpec and Thread Through FileScanBuilder
+
+**Files:**
+- Modify: `FileTable.scala`, `FileScanBuilder.scala`, `FileSourceStrategy.scala`
+- Modify: All 6 format Table + ScanBuilder classes
+
+- [ ] **Step 1: Add `bucketSpec` accessor to FileTable**
+
+```scala
+def bucketSpec: Option[BucketSpec] = catalogTable.flatMap(_.bucketSpec)
+```
+
+- [ ] **Step 2: Widen `FileSourceStrategy` method visibility**
+
+Change `private def shouldPruneBuckets`, `getExpressionBuckets`, and `genBucketSet` to `private[sql]`.
+
+- [ ] **Step 3: Add `bucketSpec` to `FileScanBuilder` constructor**
+
+```scala
+abstract class FileScanBuilder(
+ sparkSession: SparkSession,
+ fileIndex: PartitioningAwareFileIndex,
+ dataSchema: StructType,
+ val bucketSpec: Option[BucketSpec] = None)
+```
+
+Add `computeBucketSet()` method that calls `FileSourceStrategy.genBucketSet(dataFilters, spec)`.
+
+- [ ] **Step 4: Update all 6 Table classes to pass `bucketSpec`**
+
+Each Table's `newScanBuilder` passes `bucketSpec` to its ScanBuilder.
+
+- [ ] **Step 5: Update all 6 ScanBuilder classes**
+
+Each accepts `bucketSpec` parameter and passes it + `computeBucketSet()` to the Scan in `build()`.

+**Files:**
+- Modify: `sql/core/.../v2/DataSourceV2ScanExecBase.scala`
+
+- [ ] **Step 1: Update `outputPartitioning`**
+
+Check for V2 bucketed FileScan first, use case-insensitive column matching. Return `HashPartitioning`:
+
+```scala

+ HashPartitioning(bucketColumns, numPartitions)
+ case _ =>
+ keyGroupedPartitioning match {
+ // ... existing KeyedPartitioning logic unchanged ...
+ }
+ }
+}
+```
+
+Add import: `import org.apache.spark.sql.catalyst.plans.physical.HashPartitioning`
+
+- [ ] **Step 2: Optionally add `outputOrdering` for sort columns**
+
+If `bucketSpec.sortColumnNames` are present in output, report `SortOrder` (mirrors V1). Guard with `LEGACY_BUCKETED_TABLE_SCAN_OUTPUT_ORDERING` config. This enables sort-merge joins to skip an extra sort:
+
+```scala
+override def outputOrdering: Seq[SortOrder] = {
+ scan match {
+ case fileScan: FileScan if fileScan.bucketedScan &&
+ conf.getConf(SQLConf.LEGACY_BUCKETED_TABLE_SCAN_OUTPUT_ORDERING) =>

+- [ ] **Step 1: Add BatchScanExec handling in `disableBucketWithInterestingPartition`**
+
+Add new case before the default `o` case. Note: BatchScanExec is a leaf node so no `mapChildren` needed for the non-bucketed path:
+
+```scala
+case batchScan: BatchScanExec =>
+ batchScan.scan match {
+ case fileScan: FileScan if fileScan.bucketedScan =>

+```
+
+- [ ] **Step 2: Update `ExtractJoinWithBuckets` — `hasScanOperation` and `getBucketSpec`**
+
+For `hasScanOperation`, add:
+```scala
+case b: BatchScanExec => b.scan match {
+ case fs: FileScan => fs.bucketSpec.nonEmpty
+ case _ => false
+}
+```
+
+For `getBucketSpec`, use guard clause to avoid non-exhaustive match:

+3. **Bucketed join avoids shuffle** — join two 8-bucket tables on `key`, assert no `ShuffleExchangeExec`
+4. **Disable unnecessary bucketed scan** — simple `SELECT` without join should disable bucketed scan
+5. **Coalesce buckets in join** — join 8-bucket with 4-bucket table, assert no shuffle
+6. **Bucketing disabled by config** — `spark.sql.sources.bucketing.enabled=false` disables bucketed scan

+## PR Title
+
+`[SPARK-56304][SQL] Support IF NOT EXISTS for V2 file table INSERT OVERWRITE`
+
+## PR Description
+
+### What changes were proposed in this pull request?
+
+This PR adds `IF NOT EXISTS` support for `INSERT OVERWRITE ... PARTITION(...) IF NOT EXISTS` on V2 file tables.
+
+Previously, `INSERT OVERWRITE` with `IF NOT EXISTS` always threw `unsupportedIfNotExistsError` for all V2 tables. This PR lifts that restriction for tables that implement both `SupportsPartitionManagement` and `OVERWRITE_BY_FILTER` (i.e., V2 file tables like Parquet, ORC, etc.).
+
+Key changes:
+
+- **`Analyzer.ResolveInsertInto`**: Instead of unconditionally rejecting `ifPartitionNotExists`, allow it when the V2 table supports both `OVERWRITE_BY_FILTER` and `SupportsPartitionManagement`. Pass the flag and static partition spec as write options to `OverwriteByExpression`.
+- **`DataSourceV2Strategy`**: Add a new plan rule that intercepts `OverwriteByExpression` with `ifPartitionNotExists=true` on `FileTable`. It checks the filesystem for the target partition path — if the partition already exists, the write is skipped (`LocalTableScanExec`); otherwise, a normal `OverwriteByExpressionExec` proceeds.
+
+### Why are the changes needed?
+
+`IF NOT EXISTS` is a commonly used Hive/SQL idiom for idempotent partition loads. Without this, migrating workloads from V1 file sources to V2 file tables requires rewriting all `INSERT OVERWRITE ... IF NOT EXISTS` statements, which is a barrier to V2 adoption.
+
+### Does this PR introduce _any_ user-facing change?
+
+Yes. `INSERT OVERWRITE TABLE t PARTITION(p=1) IF NOT EXISTS SELECT ...` now works on V2 file tables. Previously it threw `UnsupportedOperationException`.
+
+### How was this patch tested?
+
+New test in `FileDataSourceV2WriteSuite`:
+- `INSERT OVERWRITE IF NOT EXISTS` skips write when the target partition exists
+- `INSERT OVERWRITE IF NOT EXISTS` writes when the target partition does not exist
+- `INSERT OVERWRITE` without `IF NOT EXISTS` still overwrites as expected
