This PR converts it to\n`typing.Protocol`, which is the more Pythonic pattern for a pure\ninterface. `FileFormatWriter` remains an `ABC` since it has shared\n`__enter__`/`__exit__`/`result` implementations that inheritance carries\nfor free. `FileFormatFactory` is unchanged - it matches the existing\n`AuthManagerFactory` pattern.\n\n## Changes\n\nNew format implementations can now conform structurally without\ninheriting from `FileFormatModel`. Net: 2 `ABC`s → 1 `ABC` + 1\n`Protocol`. No signature change for existing callers;\n`ParquetFormatModel(FileFormatModel)` inheritance is retained\n(`Protocol` supports explicit conformance).\n\n## Are these changes tested?\n\nYes. `tests/io/test_fileformat.py` adds two tests using a shared\n`_StructuralModel` helper:\n\n- `test_file_format_model_is_protocol` - a structurally-conforming class\n(no inheritance) passes `isinstance()` against `FileFormatModel`.\n- `test_structural_model_works_with_factory` - a structurally-conforming\nclass can be registered and retrieved via `FileFormatFactory`\nend-to-end.\n\n## Are there any user-facing changes?\n\nNo. Default behavior is unchanged."

      "message": "Make partition expression evaluation stateless (#3664)\n\n*I used CODEX to analyze this problem and create this PR. I\u0027ve reviewed\nthe code and tests and stand by them. This summary is written completely\nby a human (me) other than very light copy editing by an LLM.*\n\nCurrently, because `_ExpressionEvaluator` can\u0027t be safely shared one is\ncreated per file. That\u0027s expensive relative to actually evaluating the\nexpression. This change makes `_ExpressionEvaluator` shareable by moving\nthe mutable parts into a new `_ExpressionEvaluationVisitor` which stays\nlocal to the per-file work of evaluation.\n\nThese benchmarks are showing improvements in sub-second times, but in\nthe production workloads I tested this on it did translate to real wall\nclock improvement. But irrespective of performance gains the new\n`_ExpressionEvaluator` is safer since nothing was preventing its\naccidental concurrent reuse in the future.\n\nCODEX-generated summary follows:\n-------\nPartition pruning currently binds the same projected expression for\nevery data file because `_ExpressionEvaluator` stores the current record\nas mutable instance state. That repeated preparation is expensive, but\nsharing the existing evaluator across workers would allow concurrent\ncalls to mix records.\n\nThis separates preparation from per-record evaluation.\n`_ExpressionEvaluator` binds the expression once, while every call\ncreates a private `_ExpressionEvaluationVisitor` containing that call\u0027s\nrecord. Manifest planning can therefore prepare one evaluator per\npartition spec and safely share it across manifests and workers. This\nprovides the construction-reuse benefit targeted by #3656 without\ndepending on files within a manifest remaining sequential, and it also\nbenefits one-file manifests.\n\n## Summary\n\n- Split the prepared expression evaluator from the call-local mutable\nvisitor.\n- Reuse one prepared partition evaluator per partition spec during\nmanifest planning.\n- Add deterministic concurrent-use, prepared-state, and planner-sharing\ncoverage.\n- Add a benchmark using a realistic 15-leaf predicate across dense and\none-file manifests.\n\n## Performance\n\nI compared this branch with `main` using the partition-evaluator\nworkload in this PR. It evaluates 1,000 files with two identity\npartition fields and a 15-leaf predicate modeling five `(event_day range\nAND region_id)` branches. Timings are medians from seven samples of five\niterations.\n\n| Manifest layout | `main` | This PR | Speedup |\n|---|---:|---:|---:|\n| 1 manifest × 1,000 files | 187.928 ms | 14.413 ms | 13.04× |\n| 1,000 manifests × 1 file | 188.000 ms | 14.584 ms | 12.89× |\n\nThe improvement comes from binding the projected partition expression\nonce per partition spec instead of once per file. This is an isolated\npartition-pruning benchmark rather than an end-to-end scan-planning\nmeasurement.\n\n## Testing\n\n- `pytest tests/expressions/test_visitors.py\ntests/table/test_partition_evaluator_planning.py\ntests/table/test_init.py` (200 passed)\n- `pytest tests/benchmark/test_partition_evaluator_benchmark.py -m\nbenchmark` (2 passed)"

The name `update` is not defined in that\nscope; it is\nleft over from the preceding standalone example just above it\n(`with table.update_schema() as update:`). Copy-pasting the transaction\nsnippet\nverbatim raises `NameError: name \u0027update\u0027 is not defined`.\n\nThis changes the call to use the bound name `update_schema`, so the\ndocumented\nexample runs as written. It also matches the already-correct\n`create_table_transaction` example earlier in the same page, which uses\n`update_schema.add_column(...)`.\n\n## Are these changes tested?\n\nNo automated test: this is a one-line documentation fix with no code\nchange. I\nverified it manually against the public API:\n`Transaction.update_schema()`\nreturns an `UpdateSchema` context manager whose `add_column(path,\nfield_type,\ndoc\u003dNone, ...)` signature matches the positional call in the example, so\nthe\ncorrected snippet executes without error. `pre-commit` (markdownlint,\ncodespell,\ntrailing-whitespace/end-of-file) passes on the changed file.\n\n## Are there any user-facing changes?\n\nNo. Documentation only; there are no changes to library behavior or\npublic API."

The eager equivalent\n`to_arrow(dictionary_columns\u003d...)` worked\ncorrectly.

The fix\nrebuilds `target_schema`\nwith `pa.dictionary(pa.int32(), field.type)` for each column in\n`dictionary_columns` before\nthe cast, so the encoding is preserved end-to-end.\n\n## Are these changes tested?\n\nYes. Added `test_to_arrow_batch_reader_preserves_dictionary_columns` in\n`tests/io/test_pyarrow.py` — writes a two-column Parquet file and\nasserts that\n`_to_arrow_batch_reader_via_file_scan_tasks` returns a\ndictionary-encoded `label` column\nwhile leaving `id` as plain `int32`.\n\n## Are there any user-facing changes?\n\nYes — `to_arrow_batch_reader(dictionary_columns\u003d...)` now correctly\nreturns dictionary-encoded\narrays for the requested columns, matching the documented behaviour and\nthe existing `to_arrow`\npath.

Implements `ParquetFormatWriter` and\n`ParquetFormatModel`, registers Parquet in the `FileFormatFactory`, and\nrewrites `write_file` to dispatch through the factory using the\n`write.format.default` table property. Future formats can be added in a\nsimilar way.\n\n## Rationale for this change\n\nThe `write.format.default` table property was never read - the write\npath was hardcoded to Parquet. This PR makes the property functional.\nAlso threads `file_format` through `_to_requested_schema` /\n`ArrowProjectionVisitor` / `_construct_field` so field ID metadata keys\nare correct per format (`PARQUET:field_id` for Parquet, `iceberg.id`\nplus `iceberg.required` for ORC), preparing the write path for ORC\nsupport without changing default behavior.\n\n## Are these changes tested?\n\n- `tests/io/test_format_writers.py` adds parametrized tests modeled\nafter Java\u0027s `BaseFormatModelTests` covering round-trip, statistics,\nnull handling, context manager caching, close idempotency,\nclose-without-write, and ORC vs Parquet field ID dispatch.\n- `tests/io/test_pyarrow.py` adds `test_write_file_parquet_round_trip`\nand `test_write_file_dispatches_on_write_format_default` exercising the\nfull `write_file` path.\n\n## Are there any user-facing changes?\n\nNo. Default behavior is unchanged. Setting `write.format.default` to an\nunregistered format now raises a `ValueError`."

Because `NestedField` is a Pydantic model,\nthe\nunknown `initial_write` key is absorbed by the `**data` catch-all and\nsilently\nignored, so `apply_name_mapping` dropped every field\u0027s `write_default`\nto\n`None` (while `initial_default` was preserved). Every other place that\nrebuilds\na `NestedField` (for example in `pyiceberg/table/update/schema.py`)\nalready uses\n`write_default\u003d`; this was the one call site out of step with the\nconstructor.\n\nThe fix passes `write_default\u003dfield.write_default` to match the\nconstructor\ncontract.\n\n## Are these changes tested?\n\nYes. Added `test_mapping_preserves_field_defaults` in\n`tests/table/test_name_mapping.py`, which builds a schema whose field\ncarries\nboth `initial_default` and `write_default`, runs it through\n`apply_name_mapping`, and asserts both values survive on the mapped\nfield. It\nfails before the change (`write_default` comes back `None`) and passes\nafter.\n\n- `tests/table/test_name_mapping.py`: 13 passed\n- `tests/io/test_pyarrow_visitor.py` and `tests/test_schema.py`: 388\npassed\n(the PyArrow name-mapping visitor and schema, the current caller\nsurface)\n\nIntegration tests (Docker + Spark) were not run in this environment; the\nchange\nis pure Python type-plumbing fully exercised by the unit tests above.\n\n## Are there any user-facing changes?\n\nNo observable change in the current code paths. The only caller today is\n`pyarrow_to_schema` -\u003e `apply_name_mapping` (`pyiceberg/io/pyarrow.py`),\nwhich\nfeeds a PyArrow-derived schema whose fields never carry an Iceberg\n`write_default`, so nothing is dropped in practice right now. This is a\nlatent\ncorrectness fix: it prevents `write_default` from being silently\ndiscarded the\nmoment a name mapping is applied to any schema whose fields set a write\ndefault."

      "message": "feat: support pyarrow float16 by widening to float on read/write (#3590)\n\n# Rationale for this change\n\nPyArrow `float16` (`halffloat`) currently raises\n`UnsupportedPyArrowTypeException` during schema conversion, because\n`_ConvertToIceberg.primitive` only handles `float32` and `float64`:\n\n```python\n\u003e\u003e\u003e import pyarrow as pa\n\u003e\u003e\u003e from pyiceberg.io.pyarrow import _ConvertToIceberg, visit_pyarrow\n\u003e\u003e\u003e visit_pyarrow(pa.float16(), _ConvertToIceberg())\npyiceberg.exceptions.UnsupportedPyArrowTypeException: Column \u0027x\u0027 has an unsupported type: halffloat\n```\n\nIceberg has no half-precision float, but `float16 -\u003e float32` is\n**lossless**: every IEEE 754 half value (including the maximum finite\nvalue 65504) is exactly representable in single precision. This mirrors\nhow the same method already widens `int8`/`int16` to `IntegerType`, and\nhow `ArrowProjectionVisitor._cast_if_needed` already widens smaller\nintegers up for cross-platform compatibility. Mapping `float16 -\u003e\nFloatType` is the float analogue, so `float16` columns round-trip\ninstead of erroring.\n\nChanges (`pyiceberg/io/pyarrow.py`):\n\n- `_ConvertToIceberg.primitive`: map `pa.float16()` -\u003e `FloatType()`.\n- `ArrowProjectionVisitor._cast_if_needed`: widen smaller float types to\nthe target type on write (parallel to the existing integer-widening\nbranch), so `float16` arrays are cast to `float32`. Narrowing falls\nthrough to the existing `promote()` handling.\n\nNo dependency changes; `pyproject.toml` / `uv.lock` are untouched and\nthe imports used were already present.\n\nA note on a design choice, deferring to maintainers: widening `float16`\nsilently (rather than erroring or gating behind a config flag) follows\nthe existing `int8`/`int16 -\u003e Integer` precedent. Happy to gate it\nbehind a config option instead if you\u0027d prefer. The new float-widening\nbranch also makes `float32 -\u003e DoubleType` actually cast the array\n(parallel to int widening), so it slightly tightens float promotion in\ngeneral, not just `float16`.\n\n## Are these changes tested?\n\nYes:\n\n- `tests/io/test_pyarrow_visitor.py::test_pyarrow_float16_to_iceberg`\nasserts the schema mapping `pa.float16() -\u003e FloatType()`.\n- `tests/io/test_pyarrow.py::test__to_requested_schema_float_promotion`\nis parametrized over `f16 -\u003e Float`, `f16 -\u003e Double`, and `f32 -\u003e\nDouble`, asserting both the written PyArrow type and that the values are\npreserved.\n\nBoth pass locally, the surrounding visitor suite and the sibling\ninteger-promotion test still pass, and `make lint` (ruff, ruff-format,\nmypy, pydocstyle, codespell, uv-lock) is clean. The integration suite\n(Docker/Spark) was not run locally.\n\n## Are there any user-facing changes?\n\nYes. PyArrow tables with `float16` columns can now be converted/written\nthrough PyIceberg (they map to Iceberg `float` and are stored as\n`float32`), where they previously raised\n`UnsupportedPyArrowTypeException`. This is purely additive; existing\n`float32`/`float64` behavior is unchanged."

      "message": "fix: raise `ValidationError` for decimal precision outside range (#3585)\n\nCloses #3583\n\n# Rationale for this change\nAccording to the Iceberg specification, decimal precision must be\nbetween 1 and 38. Previously, `pyiceberg` silently accepted invalid\nvalues (such as `precision\u003d39` or `0`), which could lead to data\ncorruption or crashes downstream when encoding/decoding fixed-byte\ndecimals (matching the Java implementation\u0027s\n`IllegalArgumentException`).\n\nThis PR adds a defensive validation guard into `DecimalType.__init__` to\nraise a `ValidationError` when the precision is out of bounds `[1, 38]`.\n\nAdditionally, fixed an existing invalid type definition\n(`DecimalType(100, 2)`) inside `tests/test_schema.py` which was\nviolating the specification bounds and causing the new validation guard\nto trip during the integration test suite.\n\n## Are these changes tested?\nYes, added dedicated unit tests in `tests/test_types.py`:\n- `test_decimal_precision_validation` covers upper bounds\n(`precision\u003d39`), lower bounds (`precision\u003d0`, `precision\u003d-5`), and\nensures valid boundary values (`precision\u003d38`) work perfectly.\n\nAlso updated existing test assertions in `tests/test_schema.py` to use a\ncompliant precision value (`38`).\n\n## Are there any user-facing changes?\nYes, creating a `DecimalType` with an invalid precision will now\nexplicitly raise a `pyiceberg.exceptions.ValidationError` instead of\nfailing silently at runtime."

      "message": "fix: preserve manifest min sequence number of 0 (#3660)\n\n# Rationale for this change\n\n`ManifestWriter.to_manifest_file()` computed the manifest\u0027s minimum data\nsequence number with a truthiness fallback:\n\n```python\nmin_sequence_number \u003d self._min_sequence_number or UNASSIGNED_SEQ\n```\n\nA data sequence number of `0` is a legitimate minimum for a live file\n(files\nfrom a v1 table, or the initial commit of a v2 table). Because `0` is\nfalsy,\n`or` collapses it to `UNASSIGNED_SEQ` (`-1`), i.e. it treats a real `0`\nthe same\nas \"unset\".\n\nThis diverges from the Java reference implementation, which falls back\nto\n`UNASSIGNED_SEQ` only when the value is actually unset:\n\n```java\n// ManifestWriter#toManifestFile (apache/iceberg)\nlong minSeqNumber \u003d minDataSequenceNumber !\u003d null ? minDataSequenceNumber : UNASSIGNED_SEQ;\n```\n\nThe `-1` is not harmless. When the manifest is produced by a\nmerge/compaction\n(so its `added_snapshot_id` equals the current commit snapshot id),\n`ManifestListWriter.prepare_manifest()` treats `min_sequence_number \u003d\u003d\nUNASSIGNED_SEQ` as \"no file had an assigned sequence number\" and\noverwrites it\nwith the current, higher commit sequence number\n(`pyiceberg/manifest.py`, the `if\nwrapped_manifest_file.min_sequence_number \u003d\u003d\nUNASSIGNED_SEQ:` branch). The manifest\u0027s minimum data sequence number is\nthereby\nsilently raised, which affects sequence-number-based delete-file\napplication and\nscans.\n\nThe fix uses an explicit `None` check instead of a truthiness fallback,\nmirroring the Java writer:\n\n```python\nmin_sequence_number \u003d self._min_sequence_number if self._min_sequence_number is not None else UNASSIGNED_SEQ\n```\n\n## Are these changes tested?\n\nYes. A new parametrized regression test,\n\n`tests/utils/test_manifest.py::test_write_manifest_min_sequence_number_zero`\n(format versions 1 and 2), drives a live `EXISTING` entry with\n`sequence_number\u003d0` through `ManifestWriter.existing()` and asserts that\n`to_manifest_file().min_sequence_number \u003d\u003d 0`.\n\nThe test fails before the fix (`assert -1 \u003d\u003d 0`) and passes after it.\nThis path\nhad no prior coverage: no existing test drove a live sequence-0 entry\nthrough\n`to_manifest_file()`, which is why the defect was not caught.\n\nLocal runs (unit tests):\n- `pytest tests/utils/test_manifest.py -q` -\u003e passes.\n- `pytest tests/table/test_snapshots.py\ntests/table/test_manage_snapshots.py -q`\n  -\u003e passes.\n- `make lint` (ruff, ruff-format, mypy, pydocstyle, codespell) -\u003e clean\non the\n  changed files.\n\nThe merge/compaction integration path exercised by `prepare_manifest()`\nis\ncovered by the integration suite, which requires Docker and Spark; those\nwere\nnot run locally. The new unit test exercises the same\n`to_manifest_file()` write\npath that feeds it.\n\n## Are there any user-facing changes?\n\nNo API changes. It is a correctness fix: manifests written for live\nfiles whose\nminimum data sequence number is `0` now record `0` instead of `-1`, so a\nsubsequent merge/compaction no longer silently raises the manifest\u0027s\nminimum\ndata sequence number.\n\nSigned-off-by: Anas Khan \u003c83116240+anxkhn@users.noreply.github.com\u003e"

So\ninstead of\ntagging stale issues with `stale`, the workflow tags them with one bogus\nlabel\nliterally named `stale,security`. That breaks the workflow\u0027s own\n`stale-issue-message` (which tells users to add `not-stale`, keyed on\nthe stale\nstate) and anything else that relies on a plain `stale` label.\n\nIt also leaves `security` out of `exempt-issue-labels`, so\n`security`-labeled\nissues are still marked stale and auto-closed after 180+14 days. This is\ninconsistent with the **PR** side of the same file, which already\nexempts\n`security`:\n\n```yaml\nstale-pr-label: \u0027stale\u0027\nexempt-pr-labels: \u0027not-stale,security\u0027\n```\n\nThe value was introduced in #3125, which changed `stale-issue-label:\n\u0027stale\u0027` to\n`\u0027stale,security\u0027` in the same change that added\n`exempt-pr-labels: \u0027not-stale,security\u0027`, i.e. `security` was meant as\nan\nexemption on both sides but landed in the wrong key on the issue side.\n\nThis change makes the issue side mirror the (already correct) PR side:\n\n```yaml\nstale-issue-label: \u0027stale\u0027\nexempt-issue-labels: \u0027not-stale,security\u0027\n```\n\n## Are these changes tested?\n\nThere is no test harness for GitHub Actions workflow semantics in this\nrepo, so\nthis was validated by inspection against the pinned action\u0027s contract\nand source:\n\n- Against `actions/stale`\u0027s `action.yml` at the pinned SHA\n(`eb5cf3af3ac0a1aa4c9c45633dd1ae542a27a899`, v10.3.0):\n`stale-issue-label` is\ndocumented as \"The label to apply when an issue is stale\" (single value,\ndefault `Stale`), while `exempt-issue-labels` documents \"Separate\nmultiple\nlabels with commas\". In the action source, the stale label is applied\nverbatim\nand only the exempt labels are comma-split, confirming both effects\nabove.\n- `stale-issue-label: \u0027stale\u0027` matches the PR side of this same file and\nthe\n  Java `apache/iceberg` `stale.yml`.\n- Repo linters pass on the changed file (`check-yaml`, `codespell`,\n  trailing-whitespace, end-of-file-fixer).\n\n## Are there any user-facing changes?\n\nNo. This only affects the repository\u0027s stale-bot automation (issue\nlabeling and\nwhich issues are exempt from auto-close). No changelog label needed."

So an environment\nthat\nresolves `pyarrow\u003d\u003d17.x` under the current floor raises\n`AttributeError: module \u0027pyarrow\u0027 has no attribute \u0027uuid\u0027` (or\n`\u0027UuidType\u0027`) as\nsoon as a UUID-typed column is written, or an Arrow schema containing a\nUUID is\nconverted back to Iceberg.\n\nThis usage was added in #2007 (\"Fix UUID support\") without raising the\nfloor, and\nthe earlier `Bump PyArrow to 18.0.0` change only moved the tested/locked\nversion,\nnot the declared lower bound. This PR bumps the floor to\n`pyarrow\u003e\u003d18.0.0` for the\nfour affected extras so the declared dependency matches what the code\nactually\nrequires. See also #1174 (Minimum required pyarrow version).\n\n## Are these changes tested?\n\nThis is a dependency-floor bump with no code change, so the real guard\nis CI\nresolving the raised floor across the supported Python matrix; `uv lock\n--check`\nconfirms `uv.lock` stays in sync with `pyproject.toml`.\n\nLocally:\n- `uv lock --check` passes (lock in sync).\n- `make lint` (ruff, ruff-format, mypy, license, uv-lock, ...) all pass.\n- Existing UUID coverage still passes and exercises both affected code\npaths:\n  `tests/io/test_pyarrow_visitor.py` (60 passed),\n`tests/utils/test_schema_conversion.py -k UUID` (2 passed), and the UUID\ncases in\n  `tests/test_conversions.py` (2 passed). A manual round-trip\n  `UUIDType -\u003e pa.uuid() -\u003e pa.UuidType -\u003e UUIDType` runs clean.\n\nNo new test is added because there is no new code path to cover: the\nexisting UUID\nconversion tests already exercise `visit_uuid` and `_ConvertToIceberg`,\nand the\nfloor bump only makes the declared dependency honest. A heavier\nalternative would\nbe to version-gate `pa.uuid()`/`pa.UuidType` at runtime (as done for\n`AzureFileSystem` via `MIN_PYARROW_VERSION_SUPPORTING_AZURE_FS` in\n`pyiceberg/io/pyarrow.py`), but that keeps UUID unsupported on 17.x\nrather than\nrequiring the version the feature needs; happy to go that route instead\nif\npreferred.\n\n## Are there any user-facing changes?\n\nYes, indirectly: the minimum supported `pyarrow` for the `pyarrow`,\n`pandas`,\n`duckdb`, and `ray` extras rises from 17.0.0 to 18.0.0. This only\naffects\nenvironments currently resolving `pyarrow` 17.x, where UUID columns are\nalready\nbroken; it prevents that unsupported install rather than changing any\nworking\nbehavior.

      "message": "Feature: Incremental Append Scan (#3512)\n\n\u003c!-- Closes #2634 --\u003e\n\nCloses #2634.\n\n# Rationale for this change\n\nAdds `IncrementalAppendScan`, which reads the data appended between two\nsnapshots — the building block for incremental ingestion. Largely a\nrevival of the work in #2235; see #2634 and the previous PRs for\nmotivation.\n\nSplit out of #3364 at the reviewers\u0027 request, and builds on the\nnow-merged `BaseScan` / `ManifestGroupPlanner` refactor (#3511), so this\nPR\u0027s diff is the append-scan feature alone.\n\nThe surface mirrors Iceberg-Java\u0027s engine-facing API (snapshot IDs,\ninclusive/exclusive start, optional start) rather than the narrower\nSpark read options, since PyIceberg is increasingly used by engines\n(e.g. Polars). See the API discussion on this PR.\n\nReferences: https://github.com/apache/iceberg (Iceberg-Java and Spark)\nand https://github.com/apache/iceberg-cpp/pull/590. Inline review-aid\ncomments (prefixed `[AI reviewer aid]`) point at the relevant reference\ncode.\n\n# API\n\n`Table.incremental_append_scan(...)` returns an `IncrementalAppendScan`;\n`StagedTable` overrides it to raise, mirroring `scan()`. The scan reads\nthe rows added by **append** snapshots in `(from, to]`, projected onto\nthe table\u0027s current schema; delete / overwrite / replace snapshots in\nthe range (e.g. compaction) are ignored.\n\nThe range is set via the factory\u0027s Spark-style kwargs or the builder\nmethods, each of which returns a refined copy (like `select()` /\n`filter()`):\n\n```python\ntable.incremental_append_scan(\n    from_snapshot_id_exclusive\u003dNone,   # optional; defaults to the oldest ancestor of `to`\n    to_snapshot_id_inclusive\u003dNone,     # optional; defaults to the current snapshot\n    row_filter\u003d..., selected_fields\u003d..., case_sensitive\u003d..., options\u003d..., limit\u003d...,\n)\n\nscan.from_snapshot_id_exclusive(id)    # or .from_snapshot_id_inclusive(id)\n    .to_snapshot_id_inclusive(id)\n```\n\nThe range is held as public attributes — `from_snapshot_id` +\n`from_snapshot_inclusive` + `to_snapshot_id` — a single start slot plus\nan inclusive flag, mirroring Java\u0027s `TableScanContext` and consistent\nwith the other scans.\n\n# Changes\n\n- Range resolution mirrors Java\u0027s `BaseIncrementalScan`: an unset start\nscans from the oldest ancestor of the end; an inclusive start resolves\nto its parent as the exclusive boundary; an exclusive start is validated\nwith `is_parent_ancestor_of`, so an expired start cursor is accepted as\nlong as the lineage still passes through it; the end defaults to the\ncurrent snapshot; an empty table with no range set scans nothing.\n- Planning walks the append-only ancestors in the range, dedups the data\nmanifests whose `added_snapshot_id` is in range (set semantics via\n`ManifestFile.__eq__` / `__hash__`), and filters manifest entries to\n`ADDED`-in-range via a new `manifest_entry_filter` on\n`ManifestGroupPlanner.plan_files`. Compacted (`rewrite_data_files`)\noutput is therefore not picked up — no double counting.\n- Projects onto the table\u0027s **current** schema (matching Java/C++), so\nrows written under an older schema in the range get `NULL` for newer\ncolumns.\n- Adds snapshot helpers `ancestors_between_ids`, `is_ancestor_of`, and\n`is_parent_ancestor_of`.\n- Arrow materialization (`to_arrow` / `to_arrow_batch_reader`) is shared\nwith `DataScan` via small module-level helpers that take the projected\nschema explicitly, so `BaseScan` stays projection-free (per the #3511\nreview).\n\n# Out of scope (tracked follow-ups)\n\n- Branch selection (`use_branch`) and per-endpoint ref/tag start \u0026 end\n(`from_ref_*` / `to_ref_*`) — the rest of the engine-facing surface Java\nexposes.\n- `count()`, REST server-side planning, and user-facing doc examples\n(`mkdocs`).\n- `dictionary_columns` on `IncrementalAppendScan.to_arrow` /\n`to_arrow_batch_reader` (added to `DataScan` in #3461; the shared\nhelpers already thread it) — kept out to isolate this PR.\n\n# Are these changes tested?\n\nYes — unit tests (range resolution including unset / inclusive /\nexclusive and expired start, current-schema projection, builder and\n`update()` copies, empty table, staged-table guard) and integration\ntests (append-only, non-append snapshots ignored, compaction not\ndouble-counted, schema evolution within range, partition- and\nmetrics-evaluator pruning, disconnected snapshots), plus the\n`test_incremental_read` provision fixture.\n\n# Are there any user-facing changes?\n\nYes — the new `Table.incremental_append_scan(...)` API and\n`IncrementalAppendScan` class. No changes to existing public surface.\n\n---------\n\nCo-authored-by: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e"

      "message": "Fix duplicate filtering path in Arrow task batches (#3448)\n\nCloses #3272\n\n## What this changes\n\nThis PR updates the Arrow scan path in `_task_to_record_batches` to\navoid redundant filtering when there are no positional deletes.\n\n- Keeps predicate pushdown in `Scanner.from_fragment` as the only filter\npath when `positional_deletes` is absent.\n- Applies `current_batch.filter(pyarrow_filter)` only in the\npositional-delete path, after deletes are applied.\n- Preserves empty-batch handling after both delete application and\nconditional filtering.\n\n## Why\n\nThe previous flow could perform an extra table-level refilter even when\nthe scanner already applied the predicate. This change removes that\nstale workaround path while keeping correct behavior for positional\ndelete scenarios.\n\n## Tests\n\nAdded regression coverage in `tests/io/test_pyarrow.py`:\n\n-\n`test_task_to_record_batches_filter_without_positional_deletes_avoids_table_refilter`\n-\n`test_task_to_record_batches_filter_with_positional_deletes_handles_empty_batch`\n\nValidated locally:\n\n- `python -m pytest tests/io/test_pyarrow.py -q -k\n\"task_to_record_batches_nanos or\nfilter_without_positional_deletes_avoids_table_refilter or\nfilter_with_positional_deletes_handles_empty_batch\"`\n- `make lint`\n\n---------\n\nCo-authored-by: Gayathri Srividya Rajavarapu \u003cgayathrir@Gayathris-MacBook-Air.local\u003e\nCo-authored-by: Claude Sonnet 4.6 \u003cnoreply@anthropic.com\u003e\nCo-authored-by: Fokko Driesprong \u003cfokko@apache.org\u003e"

The current implementation unsafely\ntruncates the filter literal without checking its length relative to the\ntruncate width.\n\n## Root Cause\n\nThe `TruncateTransform.project` method calls `_truncate_array` which\nblindly truncates the literal for both `STARTS WITH` and `NOT STARTS\nWITH` predicates:\n\n```python\nelif isinstance(pred, BoundNotStartsWith):\n    return NotStartsWith(Reference(name), _transform_literal(transform, boundary))\n```\n\nFor `NOT STARTS WITH \"hello\"` with `truncate[2]`, this produces:\n- Current (unsafe): `NOT STARTS WITH \"he\"` \n- Problem: The truncated partition contains all values starting with\n\"he\" (from \"hello\", \"heat\", \"hear\", etc.), so we cannot safely exclude\nall non-\"hello\" rows\n\n## Solution\n\nAdd special handling for `BoundNotStartsWith` in the `project` method\nfollowing the Java/Go reference behavior:\n\n- **prefix_length \u003c truncate_width**: Keep original `NOT STARTS WITH`\nliteral (safe)\n- **prefix_length \u003d\u003d truncate_width**: Project to `!\u003d` instead (safe\nequality check)\n- **prefix_length \u003e truncate_width**: Return `None` (no inclusive\nprojection possible)\n\n### pyiceberg/transforms.py\n- Add explicit `NOT STARTS WITH` handling before calling\n`_truncate_array`\n- Check literal length vs truncate width and apply correct projection\nrules\n\n### tests/test_transforms.py\n- Update `test_projection_truncate_string_not_starts_with` to expect\n`None` (prefix_length \u003e width is unsafe)\n- Add `test_projection_truncate_string_not_starts_with_shorter_literal`\n(prefix_length \u003d\u003d width → `!\u003d`)\n- Add `test_projection_truncate_string_not_starts_with_original_literal`\n(prefix_length \u003c width → original)\n\n## Validation\n- `make lint` ✓ (all pre-commit hooks pass)\n- `pytest tests/test_transforms.py` → 280 passed ✓\n- All 13 string truncate projection tests pass\n\n---------\n\nCo-authored-by: Gayathri Srividya Rajavarapu \u003cgayathrir@Gayathris-MacBook-Air.local\u003e\nCo-authored-by: Kevin Liu \u003ckevinjqliu@users.noreply.github.com\u003e"

This **loosens**\n`TableScan`\u0027s abstract contract (they were abstract on `TableScan`\nbefore) without breaking existing subclasses.\n- All docstrings and explanatory comments are preserved.\n\n# Are these changes tested?\n\nThe existing `DataScan` unit and integration tests exercise the\nrefactored planning path unchanged. A regression test is added for the\nno-current-snapshot planning path, which now flows through\n`ManifestGroupPlanner`.\n\n# Are there any user-facing changes?\n\nNo. Some previously-`DataScan`-only converters (`to_duckdb` / `to_ray`)\nare now inherited by `TableScan` as well, which is purely additive.\n\n---------\n\nCo-authored-by: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e\nCo-authored-by: Kevin Liu \u003ckevinjqliu@users.noreply.github.com\u003e"
