When the intersection is empty, an IDENTITY partition can be appended to a CRC32 table, or vice versa. Subsequent writes use the table default hash while tablet pruning uses the partition hash, so committed rows can be missed. Include the non-CRC32 table default hash independently of the partition list. Preserve legacy CRC32/random signatures and allow different bucket counts when the hash algorithm matches.

Force and assert ordinary PARTITIONED joins, verify set-operation basic-side properties and remote/local thrift hash fields, and use independent arbitrary-precision high-byte, seed and NULL-tail vectors. Also verify that the local-exchange selector creates the identity partitioner, force multiple local channels, cover legacy-planner pruning, and assert the exact SHOW CREATE hash property. Generate regression golden results through the test runner and verify them with an independent result oracle. --- .../exchange/local_exchange_sink_operator.h | 4 + .../partitioner/identity_partitioner_test.cpp | 136 ++++++--- .../exec/pipeline/local_exchanger_test.cpp | 5 + .../doris/qe/IdentitySetOperationTest.java | 212 ++++++++++++++ .../test_distribution_hash_type_identity.out | 273 +++++++++++++++++- ...est_distribution_hash_type_identity.groovy | 125 ++++++-- 6 files changed, 698 insertions(+), 57 deletions(-) create mode 100644 fe/fe-core/src/test/java/org/apache/doris/qe/IdentitySetOperationTest.java diff --git a/be/src/exec/exchange/local_exchange_sink_operator.h b/be/src/exec/exchange/local_exchange_sink_operator.h index 13dbb9532b6859..db9c33aed54a14 100644 --- a/be/src/exec/exchange/local_exchange_sink_operator.h +++ b/be/src/exec/exchange/local_exchange_sink_operator.h @@ -129,6 +129,10 @@ class LocalExchangeSinkOperatorX final : public DataSinkOperatorXset_low_memory_mode(); } +#ifdef BE_TEST + PartitionerBase* partitioner_for_test() const { return _partitioner.get(); } +#endif + private: friend class LocalExchangeSinkLocalState; friend class ShuffleExchanger; diff --git a/be/test/exec/partitioner/identity_partitioner_test.cpp b/be/test/exec/partitioner/identity_partitioner_test.cpp index 9b12b00b8a2fb1..0972aadda05941 100644 --- a/be/test/exec/partitioner/identity_partitioner_test.cpp +++ b/be/test/exec/partitioner/identity_partitioner_test.cpp @@ -18,6 +18,7 @@ #include #include +#include #include #include #include @@ -187,45 +188,112 @@ TEST_F(IdentityPartitionerTest, Crc32DiffersFromIdentity) { EXPECT_TRUE(differs); } -TEST(IdentityHashTest, FixedWidthAndLegacyTypes) { - constexpr uint32_t n = 257; - auto hash_bytes = [](const void* value, size_t size, uint32_t seed = 0) { - const auto* bytes = reinterpret_cast(value); - uint64_t remainder = seed; - for (size_t i = size; i > 0; --i) { - remainder = (remainder * 256 + bytes[i - 1]) % n; +namespace { + +// Like the FE pruning tests' BigInteger oracle, construct the entire unsigned value before +// taking the modulus.

From 4ee584f37d0a1620ca43778912b91783c3364fc8 Mon Sep 17 00:00:00 2001 From: Zhigao Hong Date: Thu, 17 Sep 2026 23:55:08 +0800 Subject: [PATCH 26/33] [fix](fe): Reject legacy identity metadata exports Problem Summary: Older remote-Doris FEs ignore the new distribution hash type in table metadata and prune identity buckets with CRC32. A BIGINT value of 1 in an eight-bucket identity table is stored in bucket 1, but a metadata-version-140 client selects bucket 7 and misses the committed row. The same CRC32 table is read correctly. Reject identity metadata exports to clients without version 141 support before copying table or partition metadata. Return an empty required table_meta field so the error survives Thrift serialization. Keep CRC32 and random-distribution exports unchanged. Remote Doris clients with missing metadata versions or versions below 141 receive an explicit upgrade error when accessing identity tables, instead of silently pruning the wrong tablets.

Adapt the actual test caller instead of adding a compatibility overload or default arguments.

A zero-key DistributionSpecHash satisfies every hash REQUIRE demand - containsSatisfy() is vacuously true on the empty equivalence map - so a parent that needs a hash exchange would wrongly consider the requirement already satisfied and skip its enforcer. Both the storage-layout branch (which accepted the empty result via 0 == 0) and the generic-loop tail could produce this spec before the fix. Restore the normalization: add a createHash overload that carries the storage hash type and still returns GATHER for an empty key list, use it in the generic-loop tail, and require a non-empty key set before the storage-layout branch advertises the basic child's layout.

A fragment mixing CRC32 and IDENTITY inputs serialized WITHOUT the field, and BE-native bucket local exchanges then fell back to their default CRC32 partitioner with no error - identity-routed rows were silently re-bucketed by the wrong hash function, corrupting multi-instance aggregation and equality joins. Reject the genuinely mixed case at serialization time instead of letting the fallback guess. PlanNode gains collectStorageHashTypes() (fed by the nodes that own a layout opinion: OLAP scans, exchanges, local exchanges; nodes without one stay silent), and PlanFragment.toThrift uses it to distinguish "no bucketed storage here" (schema scans, empty sets) from "both CRC32 and IDENTITY under this root" - only the latter fails, with a message naming the conflicting types. Also drop the never-called three-argument DataDistribution constructor on BE: per-operator hash type construction was dead code that only documented a propagation this change does not implement, while the fragment-scoped stamping in _add_local_exchange_impl remains the only writer. --- be/src/exec/pipeline/dependency.h | 9 +-- .../apache/doris/planner/ExchangeNode.java | 5 ++ .../doris/planner/LocalExchangeNode.java | 5 ++ .../apache/doris/planner/OlapScanNode.java | 5 ++ .../apache/doris/planner/PlanFragment.java | 13 ++++ .../org/apache/doris/planner/PlanNode.java | 24 ++++++ .../planner/LocalShuffleNodeCoverageTest.java | 78 +++++++++++++++++++ 7 files changed, 134 insertions(+), 5 deletions(-) diff --git a/be/src/exec/pipeline/dependency.h b/be/src/exec/pipeline/dependency.h index e0ee76ff5887a7..c719881b2000d3 100644 --- a/be/src/exec/pipeline/dependency.h +++ b/be/src/exec/pipeline/dependency.h @@ -791,14 +791,13 @@ struct DataDistribution { DataDistribution(TLocalPartitionType::type type) : distribution_type(type) {} DataDistribution(TLocalPartitionType::type type, const std::vector& partition_exprs_) : distribution_type(type), partition_exprs(partition_exprs_) {} - DataDistribution(TLocalPartitionType::type type, const std::vector& partition_exprs_, - TDistributionHashType::type distribution_hash_type_) - : distribution_type(type), - partition_exprs(partition_exprs_), - distribution_hash_type(distribution_hash_type_) {} DataDistribution(const DataDistribution& other) = default; bool need_local_exchange() const { return distribution_type != TLocalPartitionType::NOOP; } DataDistribution& operator=(const DataDistribution& other) = default; + // Hash type is fragment-scoped by design: PipelineFragmentContext::_add_local_exchange_impl + // stamps the fragment's distribution_hash_type onto every BUCKET_HASH_SHUFFLE local exchange + // (FE derives it from the fragment root and rejects mixed-layout fragments before sending), + // so per-operator construction never needs to carry one.
