From 87f38bf2c65f765138248c5bd7159672cbee9e6e Mon Sep 17 00:00:00 2001 From: daidai Date: Thu, 6 Aug 2026 11:14:35 +0800 Subject: [PATCH 01/14] [feature](iceberg) Support Iceberg V3 default values Issue Number: None Related PR: #65851 Problem Summary: Iceberg V3 separates initial defaults for fields absent from older data files from write defaults for omitted fields. Doris branch-4.1 previously returned NULL for missing fields and did not consume Iceberg write defaults consistently across schema evolution, branch writes, equality deletes, and the V1/V2 readers. This change carries typed defaults by field ID, materializes missing values in both reader generations, pins write planning and MERGE distribution to the same target schema/spec, and applies write defaults for omitted columns or explicit DEFAULT. It also keeps V1 byte equality deletes compatible across STRING/VARBINARY carriers and adds FE-to-Thrift and ORC byte-level coverage. The latest semantic rebase integrates branch-4.1's generation-aware Iceberg metadata cache by acquiring writable tables through the catalog-generation fence instead of retaining the obsolete fresh-load helper. Existing Iceberg VARIANT read/write validation and transform-aware writer distribution are preserved; VARIANT default values remain outside this backport scope. Support Iceberg V3 initial defaults for fields absent from older files and write defaults for omitted columns or explicit DEFAULT values. VARIANT default values are not included. - Test: Unit Test / Regression test / Manual test - Latest branch-4.1 rebase: full FE build, Checkstyle, 5,148 main sources, and 1,308 test sources passed via `./build.sh --fe -j 12` - Latest branch-4.1 rebase: `IcebergExternalMetaCacheTest` 76/76 and `IcebergTransactionTest` 25/25 passed - Previous candidate: full ASAN BE build/link and focused BE UT 6/6 passed; BE feature paths are unchanged by this FE-only conflict resolution - Previous candidate: `test_iceberg_write_default` passed 1/1 and generated its `.out` through the regression runner - Current rebase: `git range-diff`, conflict-marker scan, and `git diff --check` passed - Other external Iceberg regression suites were not rerun after the latest rebase - Behavior changed: Yes. Iceberg reads and writes now apply V3 initial and write defaults for supported non-VARIANT types; writable-table acquisition follows branch-4.1 catalog-generation fencing. - Does this need

Issue Number: None Related PR: #66538 Problem Summary: The branch-4.1 Iceberg V3 default-value backport still had correctness gaps in V1 equality-delete carrier planning, pre-filter complex defaults, EXPLAIN context lifetime, batch compatibility preflight, required-field evolution, ORC FIXED encoding, timestamptz semantics, and mixed-version ORC binary writes. Preserve one shared physical root while materializing delete-schema-specific carriers, move defaults and validation to the correct execution boundary, retain pinned write metadata through planning, and add focused compatibility fences and tests. ### Release note None ### Check List (For Author) - Test: Unit Test and local ASAN BE/FE build - 175 focused FE tests and 115 focused BE tests passed - Behavior changed: Yes (fixes correctness and rolling-upgrade safety for the new Iceberg V3 default-value feature) - Does this need documentation: No --- be/src/format/orc/vorc_reader.cpp | 2 +- .../format/parquet/vparquet_column_reader.cpp | 6 +- be/src/format/table/iceberg_default_value.h | 99 ++- be/src/format/table/iceberg_reader.cpp | 579 ++++++++++++++---- be/src/format/table/iceberg_reader.h | 25 +- be/src/format/table/table_format_reader.h | 2 +- .../format/transformer/vorc_transformer.cpp | 24 +- be/src/format_v2/column_mapper.cpp | 25 +- be/src/format_v2/column_mapper.h | 3 + be/src/format_v2/table/iceberg_reader.cpp | 214 +++++-- be/src/format_v2/table/iceberg_reader.h | 3 + .../table/iceberg/iceberg_reader_test.cpp | 281 +++++++++ .../transformer/vorc_transformer_test.cpp | 41 ++ be/test/format_v2/column_mapper_test.cpp | 13 + .../format_v2/table/iceberg_reader_test.cpp | 132 ++++ .../datasource/iceberg/IcebergUtils.java | 61 +- .../iceberg/IcebergWriteSchemaContext.java | 12 +- .../iceberg/source/IcebergScanNode.java | 15 +- .../trees/plans/commands/ExplainCommand.java | 18 +- .../iceberg/IcebergDDLAndDMLPlanTest.java | 21 + .../datasource/iceberg/IcebergUtilsTest.java | 59 ++ .../IcebergWriteSchemaContextTest.java | 21 + .../iceberg/source/IcebergScanNodeTest.java | 49 ++ 23 files changed, 1456 insertions(+), 249 deletions(-) diff --git a/be/src/format/orc/vorc_reader.cpp b/be/src/format/orc/vorc_reader.cpp index 12a54053996051..73cc96ae2dd1e9 100644 --- a/be/src/format/orc/vorc_reader.cpp +++ b/be/src/format/orc/vorc_reader.cpp @@ -2351,7 +2351,7 @@ Status OrcReader::_fill_doris_data_column(const std::string& col_name, if (iceberg_field != nullptr) { RETURN_IF_ERROR(iceberg::append_initial_default( *iceberg_field, doris_type, num_values, &_nested_initial_default_values, - &doris_field));

Issue Number: None Related PR: #66538 Problem Summary: The branch-4.1 backport could bind branch writes to historical branch metadata, leave final MERGE replay and production scheduling boundaries unguarded, lose split-local equality-delete schemas in V2 tests, defer required nested-field validation until after lazy filtering, and assert against physical rather than filtered row counts while materializing V1 defaults. Pin branch writers to the table-current schema, validate projected required fields before reader initialization, preserve split-local delete metadata, use filtered block cardinality for missing-column materialization, and add focused production-boundary, unit, and regression coverage. ### Release note None ### Check List (For Author) - Test: Unit Test, regression test, and ASAN build - Focused FE tests: IcebergWriteSchemaContextTest 17/17, IcebergTransactionTest 26/26, and production scheduling entry tests 2/2 - Focused BE tests: writer, V1 required-field validation, and V2 split-local schema tests 4/4 - Iceberg initial-default, write-evolution, branch/tag, and schema-ref regression suites passed; changed outputs were generated by the runner - Full ASAN BE+FE build and final incremental ASAN BE build passed - clang-format, format check, and git diff check passed - Behavior changed: Yes (fixes branch write-schema binding, required-field validation, and filtered default materialization for the Iceberg V3 backport) - Does this need documentation: No --- be/src/format/table/iceberg_reader.cpp | 152 +++++++++++++- be/src/format/table/iceberg_reader.h | 5 +- .../iceberg/viceberg_table_writer_test.cpp | 3 +- .../table/iceberg/iceberg_reader_test.cpp | 198 +++++++++++++++++- .../format_v2/table/iceberg_reader_test.cpp | 65 ++++++ .../iceberg/IcebergWriteSchemaContext.java | 81 ++----- .../iceberg/IcebergTransactionTest.java | 48 +++++ .../IcebergWriteSchemaContextTest.java | 190 +++++++---------- .../iceberg/source/IcebergScanNodeTest.java | 149 +++++++++++++ ...berg_branch_tag_schema_change_extended.out | 2 +- .../iceberg/test_iceberg_initial_defaults.out | 9 +- ...test_iceberg_schema_ref_actions_matrix.out | 5 +- .../test_iceberg_write_evolution_refs.out | 7 +- ...g_branch_tag_schema_change_extended.groovy | 9 +- .../test_iceberg_initial_defaults.groovy | 8 +- ...t_iceberg_schema_ref_actions_matrix.groovy | 35 ++-- .../test_iceberg_write_evolution_refs.groovy | 24 +-- 17 files changed, 735 insertions(+), 255 deletions(-) diff --git a/be/src/format/table/iceberg_reader.cpp b/be/src/format/table/iceberg_reader.cpp index b8683b5877fb7d..de8f0d36afbcc5 100644 --- a/be/src/format/table/iceberg_reader.cpp +++ b/be/src/format/table/iceberg_reader.cpp @@ -102,7 +102,7 @@ template const NullMap* project_iceberg_parent_null_map(const NullMap* own_null_map, const NullMap* ancestor_null_map, size_t rows, const Offsets& offsets, size_t child_rows, - NullMap* projected_null_map) { + NullMap* const projected_null_map) { if (own_null_map == nullptr && ancestor_null_map == nullptr) { return nullptr; } @@ -124,6 +124,9 @@ const NullMap* project_iceberg_parent_null_map(const NullMap* own_null_map, return projected_null_map; } +// This recursive type dispatcher mirrors Iceberg's nested types; DORIS_CHECK expansion inflates +// the measured complexity. +// NOLINTNEXTLINE(readability-function-cognitive-complexity) Status validate_iceberg_required_field(const schema::external::TField& field, const DataTypePtr& data_type, const ColumnPtr& column, const NullMap* ancestor_null_map = nullptr) { @@ -221,6 +224,96 @@ Status validate_iceberg_required_field(const schema::external::TField& field, } } +Status validate_projected_missing_iceberg_field(const schema::external::TField& field, + const DataTypePtr& data_type, + const cctz::time_zone* timezone) { + DORIS_CHECK(field.__isset.is_optional); + // A missing optional field without an initial default materializes as NULL.

Issue Number: None Related PR: #66538 Problem Summary: V1 Iceberg scans could size missing equality-delete carriers from a stale physical read count after predicates had filtered the visible block to zero, causing equality filters to access zero-row work buffers with nonempty keys. Hidden equality carriers could also fall through ordinary table-default materialization and abort because they are not table schema children. For nested historical equality keys, a projected struct could be reused by child name even when the field ID was dropped or re-added, which either failed initialization or probed deletes against the new same-name field.

Issue Number: None Related PR: #66538 Problem Summary: Forced V1 Iceberg scans validated required fields before equality deletes and allowed physical predicates to hide invalid historical NULL values. The previous equality-delete carrier fix also broadened Parquet file-column aliases globally, which broke schema-evolution row-id reads, while property updates could mutate a frozen query snapshot instead of the writable table. Apply equality deletes before requiredness checks, defer only predicates touching required fields, restrict duplicate Parquet mappings to explicit equality-delete carriers, and obtain a writable table for property changes. Update focused unit coverage and the external regression error contract. ### Release note Fix Iceberg V1 schema-evolution validation and related external-table regressions. ### Check List (For Author) - Test: No test run (compilation and tests were explicitly skipped) - Added focused BE unit coverage for equality-delete ordering and required-field predicate deferral - Updated FE unit mocks and the external regression error expectation - clang-format, format check, and git diff check passed - Behavior changed: Yes (required-field validation now observes logical row visibility consistently) - Does this need documentation: No --- be/src/format/parquet/vparquet_reader.cpp | 33 ++- be/src/format/parquet/vparquet_reader.h | 7 + be/src/format/table/iceberg_reader.cpp | 221 ++++++++++++++++-- be/src/format/table/iceberg_reader.h | 15 ++ .../table/iceberg/iceberg_reader_test.cpp | 202 +++++++++++++++- .../iceberg/IcebergMetadataOps.java | 2 +- .../IcebergMetadataOpsValidationTest.java | 6 +- .../iceberg/test_gen_iceberg_by_api.groovy | 9 +- 8 files changed, 450 insertions(+), 45 deletions(-) diff --git a/be/src/format/parquet/vparquet_reader.cpp b/be/src/format/parquet/vparquet_reader.cpp index 4356b3f0e06817..672537629dc6dc 100644 --- a/be/src/format/parquet/vparquet_reader.cpp +++ b/be/src/format/parquet/vparquet_reader.cpp @@ -461,26 +461,37 @@ Status ParquetReader::init_reader( _table_column_names = &all_column_names; auto schema_desc = _file_metadata->schema(); - // A projected Iceberg struct and its raw historical equality-delete carrier can intentionally - // map to the same physical root.

Issue Number: None Related PR: #66538 Problem Summary: TeamCity External Regression exposed two failures introduced by the Iceberg V3 default and required-field handling. Physical COUNT pushdown returned synthetic NULL placeholder columns that were mistaken for invalid required values. Schema-evolution row-id fetch appended a valid missing-column batch and then its zero-row EOF probe re-evaluated the default, shrinking the accumulated column to zero and triggering a row-count DCHECK. Disable physical COUNT pushdown only when projected required-field validation needs real values, and make zero-row missing-column fill a no-op so accumulated row-id results remain intact. Add focused coverage using the exact schema-evolution fixture. ### Release note Fix Iceberg count queries and schema-evolution top-N reads. ### Check List (For Author) - Test: Unit Test - ASAN BE UT: 37/37 passed across ParquetReadLinesTest, IcebergReaderTest, and EqualityDeleteTest - clang-format, format check, and git diff check passed - Full ASAN BE build was stopped at user request after 260/1535 build steps; completion is not claimed - Behavior changed: Yes (COUNT validation reads real required values and row-id EOF probes preserve accumulated missing columns) - Does this need documentation: No --- .../format/parquet/vparquet_group_reader.cpp | 5 + be/src/format/table/iceberg_reader.cpp | 6 + be/test/format/parquet/parquet_read_lines.cpp | 148 ++++++++++++++++++ .../table/iceberg/iceberg_reader_test.cpp | 10 +- 4 files changed, 168 insertions(+), 1 deletion(-) diff --git a/be/src/format/parquet/vparquet_group_reader.cpp b/be/src/format/parquet/vparquet_group_reader.cpp index 9cb4cf35f7632d..780e7f2211b55d 100644 --- a/be/src/format/parquet/vparquet_group_reader.cpp +++ b/be/src/format/parquet/vparquet_group_reader.cpp @@ -849,6 +849,11 @@ Status RowGroupReader::_fill_partition_columns( Status RowGroupReader::_fill_missing_columns( Block* block, size_t rows, const std::unordered_map& missing_columns) { + // Row-id fetch appends batches to one Block.

Issue Number: None Related PR: #66538 Problem Summary: The Iceberg V3 backport could serialize two same-name nested fields through one name-keyed Column entry after a field was dropped and re-added, losing one field ID in the FE-to-BE schema carrier. The V2 reader could also use footer COUNT or MIN/MAX aggregates for mappings that require Iceberg required-field validation, bypassing the normal materialization error for visible NULL values. Preserve complete struct carriers positionally while retaining name matching for pruned slot types, and disable metadata aggregate pushdown whenever a projected mapping or nested child requires requiredness validation. ### Release note Fix Iceberg schema-evolution field identity and required-field aggregate validation. ### Check List (For Author) - Test: Unit Test - ExternalUtilTest: 11/11 passed with FE compile and Checkstyle - IcebergV2ReaderTest.RequiredMappingDisablesFooterAggregatePushdown: 1/1 passed under ASAN - Full ASAN BE UT target compiled and linked;

Issue Number: None Related PR: #66538 Problem Summary: Iceberg missing columns now carry a VLiteral default expression, so RowGroupReader::_fill_missing_columns takes the default-value branch and replaces the whole Block column with one sized to the current batch. The row-id fetch path builds its ParquetReader with batch_size 1 and appends every batch into a single Block, so that replacement truncated the accumulated column and tripped the block/column size check in vparquet_group_reader.cpp, aborting the BE and taking the rest of the external regression run down with it. Required-field validation also walked every tuple slot, including the slots a count(*) scan keeps but never materializes, so a column that was never read from the file reported a spurious "Required Iceberg field contains NULL". Size the replacement column by the rows it already holds plus the rows the batch produced, and validate only the columns the scan actually reads. ### Release note Fix an Iceberg BE crash when fetching rows by row id from a table with a defaulted column, and a spurious required-field error on count(*). ### Check List (For Author) - Test: Unit Test - Verified under ASAN with a temporary two-row-id read_lines case: it reproduced the exact CI abort (block rows = 2 , column rows = 1, col name = id) before the fix and passes after - Reverting the validation guard alone makes the unmaterialized-slot case fail, and reverting it with the pristine fixture makes rejects_visible_null_for_required_v1_field fail, which is why set_projected_table_field now records the column as read - 1029 parquet/iceberg/table-reader/column-mapper BE unit tests pass - clang-format and git diff --check passed - Behavior changed: Yes (row-id fetch keeps accumulated default columns intact, and count(*) no longer fails on required slots it does not materialize) - Does this need documentation: No --- be/src/format/parquet/vparquet_group_reader.cpp | 11 +++++++---- be/src/format/table/iceberg_reader.cpp | 12 ++++++++++++ be/test/format/table/iceberg/iceberg_reader_test.cpp | 3 +++ 3 files changed, 22 insertions(+), 4 deletions(-) diff --git a/be/src/format/parquet/vparquet_group_reader.cpp b/be/src/format/parquet/vparquet_group_reader.cpp index 780e7f2211b55d..a6a1dce1cc06c3 100644 --- a/be/src/format/parquet/vparquet_group_reader.cpp +++ b/be/src/format/parquet/vparquet_group_reader.cpp @@ -869,12 +869,15 @@ Status RowGroupReader::_fill_missing_columns( ColumnPtr result_column_ptr; // PT1 => dest primitive type RETURN_IF_ERROR(ctx->execute(block, result_column_ptr)); + // Row-id fetch appends several batches into one Block, so this column must end up + // holding the rows it already carries plus the rows this batch produced.

Issue Number: None Related PR: #66538 Problem Summary: The previous commit let IcebergTableReader::_validate_required_table_columns skip any tuple slot missing from _all_required_col_names, on the theory that a `count(*)` scan keeps a required slot it never materializes. The external regression run disproved it: the four remaining `Required Iceberg field ... contains NULL` failures come from FileScannerV2, not from this V1 reader, so the exemption changed no test outcome while relaxing a contract check and forcing the test fixture to model a projected field as read. Restore the original validation and fixture; the row-id fetch column-sizing fix in vparquet_group_reader.cpp is unaffected and stays. ### Release note None ### Check List (For Author) - Test: Unit Test - IcebergReaderTest, ParquetReadLinesTest and IcebergV2ReaderTest: 116/116 pass under ASAN - 1029 parquet/iceberg/table-reader/column-mapper BE unit tests pass - clang-format and git diff --check passed - Behavior changed: Yes (V1 required-field validation returns to covering every projected slot) - Does this need documentation: No --- be/src/format/table/iceberg_reader.cpp | 12 ------------ be/test/format/table/iceberg/iceberg_reader_test.cpp | 3 --- 2 files changed, 15 deletions(-) diff --git a/be/src/format/table/iceberg_reader.cpp b/be/src/format/table/iceberg_reader.cpp index db45c31eb3dc2b..63e6a35ec73f0e 100644 --- a/be/src/format/table/iceberg_reader.cpp +++ b/be/src/format/table/iceberg_reader.cpp @@ -1110,18 +1110,6 @@ Status IcebergTableReader::_validate_required_table_columns(Block* block) const DORIS_CHECK(block != nullptr); DORIS_CHECK(_col_name_to_block_idx != nullptr); for (const auto& [field_id, column_name] : _id_to_block_column_name) { - // Only the columns this scan materializes carry file data.

Issue Number: None Related PR: #66538 Problem Summary: This backport added a runtime required-field check that upstream does not have: ColumnMapping::reject_null_value, IcebergTableReader::_validate_required_mapping_column, _validate_required_table_columns, and the predicate deferral built to feed them (_required_validation_slot_ids, _deferred_required_column_predicates). apache/master keeps only the mapping-time contract, reject_missing_required_field, which rejects a required field that is absent from the data file. The runtime scan repeatedly reported "Required Iceberg field ... contains NULL" for columns a COUNT(*) plan never decodes, because such a plan keeps its projected columns purely as row-count placeholders. Remove that machinery and keep the mapping-time check, matching upstream. Separately, OrcReader::_fill_missing_columns had the same batch-sizing bug already fixed for Parquet: the row-id fetch path appends several batches into one Block, so replacing the column with one sized to the current batch truncated it and aborted the BE. ### Release note Fix spurious "Required Iceberg field contains NULL" errors and an Iceberg BE crash when fetching rows by row id from an ORC table with a defaulted column. ### Check List (For Author) - Test: Unit Test - Full BE unit test run under ASAN: 10435 tests, identical failure set to the pre-change baseline (25, all missing local test data: JsonReader, apache-orc examples, shredded variant) - 1022 parquet/iceberg/table-reader/column-mapper tests pass - Verified locally that COUNT(*) over a required Iceberg field now returns its rows instead of the spurious error, and that a required-field predicate no longer empties the Block - clang-format and git diff --check passed - Behavior changed: Yes (a visible NULL in a required Iceberg field is no longer rejected at read time, matching apache/master) - Does this need documentation: No --- be/src/format/orc/vorc_reader.cpp | 12 +- be/src/format/table/iceberg_reader.cpp | 319 +----------------- be/src/format/table/iceberg_reader.h | 11 - be/src/format_v2/column_mapper.cpp | 23 +- be/src/format_v2/column_mapper.h | 3 - be/src/format_v2/table/iceberg_reader.cpp | 126 +------ be/src/format_v2/table/iceberg_reader.h | 6 - .../table/iceberg/iceberg_reader_test.cpp | 128 ------- be/test/format_v2/column_mapper_test.cpp | 13 - .../format_v2/table/iceberg_reader_test.cpp | 226 ------------- .../iceberg/test_gen_iceberg_by_api.groovy | 7 +- 11 files changed, 22 insertions(+), 852 deletions(-) diff --git a/be/src/format/orc/vorc_reader.cpp b/be/src/format/orc/vorc_reader.cpp index 73cc96ae2dd1e9..d9ac1478d3e738 100644 --- a/be/src/format/orc/vorc_reader.cpp +++ b/be/src/format/orc/vorc_reader.cpp @@ -1566,12 +1566,16 @@ Status OrcReader::_fill_missing_columns( // PT1 => dest primitive type ColumnPtr result_column_ptr; RETURN_IF_ERROR(ctx->execute(block, result_column_ptr)); + // Row-id fetch appends several batches into one Block, so this column must end up + // holding the rows it already carries plus the rows this batch produced.
