From 2942170f7f02ab808b8e3ed9e33e731fc7e17fc3 Mon Sep 17 00:00:00 2001 From: kexianda Date: Fri, 24 Jul 2026 14:07:57 +0800 Subject: [PATCH 1/2] feat: add monotonic and slab allocators HashStringAllocator and memory::StlAllocator are slow for small, frequent allocations. Add monotonic and slab allocators to accelerate these allocation patterns. Microbenchmarks show that SlabAllocator is about 4x faster than HashStringAllocator and about 40x faster than memory::StlAllocator. ``` ============================================================================ [...]s/unstable/SlabAllocatorBenchmark.cpp relative time/iter iters/s ============================================================================ HashStringAllocatorFifoAllocFree256K_8Threads 58.47ns 17.10M AlignedStlAllocatorFifoAllocFree256K_8Threads 10.372% 563.70ns 1.77M SlabAllocatorFifoAllocFree256K_8Threads 384.63% 15.20ns 65.79M ``` In the append-only scenario, the monotonic allocator is about 12x faster than HashStringAllocator. ``` ============================================================================ [...]StringMonotonicAllocatorBenchmark.cpp relative time/iter iters/s ============================================================================ HashStringAllocatorAllocateNoFree 6.22s 160.90m MonotonicMemoryResourceAllocateNoFree 1287.9% 482.60ms 2.07 ``` For StringView compatibility, keep supporting cases where HashStringAllocator is still used, such as aggregation. Store a contiguous-string flag in the high bit of the pointer to preserve compatibility while enabling faster paths. --- bolt/benchmarks/unstable/CMakeLists.txt | 13 + .../unstable/SlabAllocatorBenchmark.cpp | 328 ++++++++++ bolt/common/memory/CMakeLists.txt | 1 + bolt/common/memory/HashStringAllocator.cpp | 11 +- bolt/common/memory/MallocAllocator.cpp | 4 + bolt/common/memory/MallocAllocator.h | 2 + bolt/common/memory/MemoryAllocator.h | 2 + bolt/common/memory/MemoryPool.h | 27 + bolt/common/memory/MemoryResource.cpp | 250 ++++++++ bolt/common/memory/MemoryResource.h | 260 ++++++++ bolt/common/memory/MmapAllocator.cpp | 5 + bolt/common/memory/MmapAllocator.h | 2 + bolt/common/memory/tests/CMakeLists.txt | 1 + .../memory/tests/HashStringAllocatorTest.cpp | 22 +- bolt/common/memory/tests/MemoryPoolTest.cpp | 29 + .../common/memory/tests/SlabAllocatorTest.cpp | 601 ++++++++++++++++++ bolt/dwio/dwrf/test/WriterFlushTest.cpp | 517 ++++++--------- .../dwrf/writer/IntegerDictionaryEncoder.h | 6 +- .../dwrf/writer/StringDictionaryEncoder.h | 6 +- bolt/exec/ContainerRow2RowSerde.cpp | 5 +- bolt/exec/ContainerRowSerde.cpp | 7 +- bolt/exec/GroupingSet.cpp | 21 +- bolt/exec/GroupingSet.h | 1 + bolt/exec/HashTable.cpp | 34 +- bolt/exec/HashTable.h | 9 +- bolt/exec/RowContainer.cpp | 167 +++-- bolt/exec/RowContainer.h | 153 ++++- bolt/exec/Spill.cpp | 2 +- bolt/exec/Spill.h | 2 +- bolt/exec/SpillFile.cpp | 2 +- bolt/exec/SpillFile.h | 2 +- bolt/exec/Spiller.h | 7 +- bolt/exec/VectorHasher.cpp | 12 +- bolt/exec/benchmarks/CMakeLists.txt | 37 ++ .../HashStringMonotonicAllocatorBenchmark.cpp | 204 ++++++ bolt/exec/benchmarks/HashTableBenchmark.cpp | 231 ++++++- .../RowContainerStoreStringBenchmark.cpp | 258 ++++++++ .../RowContainerVarcharOrderByBenchmark.cpp | 384 +++++++++++ .../StlContainerAllocatorBenchmark.cpp | 547 ++++++++++++++++ bolt/exec/meta/MetaRowSorterApi.h | 2 +- bolt/exec/tests/HashJoinTest.cpp | 134 ++++ bolt/exec/tests/OrderByTest.cpp | 54 +- bolt/functions/lib/SubscriptUtil.h | 10 +- bolt/jit/tests/RowEqRowIRTest.cpp | 80 +++ bolt/jit/tests/ThrustJITv2Test.cpp | 2 +- bolt/type/StringView.h | 22 +- bolt/type/tests/StringViewTest.cpp | 18 + bolt/vector/ComplexVector.h | 15 +- 48 files changed, 3992 insertions(+), 517 deletions(-) create mode 100644 bolt/benchmarks/unstable/SlabAllocatorBenchmark.cpp create mode 100644 bolt/common/memory/MemoryResource.cpp create mode 100644 bolt/common/memory/MemoryResource.h create mode 100644 bolt/common/memory/tests/SlabAllocatorTest.cpp create mode 100644 bolt/exec/benchmarks/HashStringMonotonicAllocatorBenchmark.cpp create mode 100644 bolt/exec/benchmarks/RowContainerStoreStringBenchmark.cpp create mode 100644 bolt/exec/benchmarks/RowContainerVarcharOrderByBenchmark.cpp create mode 100644 bolt/exec/benchmarks/StlContainerAllocatorBenchmark.cpp diff --git a/bolt/benchmarks/unstable/CMakeLists.txt b/bolt/benchmarks/unstable/CMakeLists.txt index b3a6c55d8..48890a365 100644 --- a/bolt/benchmarks/unstable/CMakeLists.txt +++ b/bolt/benchmarks/unstable/CMakeLists.txt @@ -31,10 +31,15 @@ set(BOLT_BENCHMARK_DEPS ${FOLLY_BENCHMARK} ) +if(NOT APPLE) + find_package(jemalloc CONFIG REQUIRED) +endif() + add_executable(bolt_memory_alloc_benchmark MemoryAllocationBenchmark.cpp) add_executable(bolt_memory_alloc_contiguous_benchmark AllocateContiguousBenchmark.cpp) add_executable(bolt_memory_realloc_benchmark ReallocateBenchmark.cpp) add_executable(bolt_memory_realloc_contiguous_benchmark ReallocateContiguousBenchmark.cpp) +add_executable(bolt_slab_allocator_benchmark SlabAllocatorBenchmark.cpp) target_link_libraries(bolt_memory_alloc_benchmark ${BOLT_BENCHMARK_DEPS} bolt_memory pthread) target_link_libraries( @@ -42,6 +47,14 @@ target_link_libraries( ) target_link_libraries(bolt_memory_realloc_benchmark ${BOLT_BENCHMARK_DEPS} bolt_memory pthread) +target_link_libraries( + bolt_slab_allocator_benchmark + ${BOLT_BENCHMARK_DEPS} + bolt_memory + jemalloc::jemalloc + pthread +) + target_link_libraries( bolt_memory_realloc_contiguous_benchmark ${BOLT_BENCHMARK_DEPS} bolt_memory pthread ) diff --git a/bolt/benchmarks/unstable/SlabAllocatorBenchmark.cpp b/bolt/benchmarks/unstable/SlabAllocatorBenchmark.cpp new file mode 100644 index 000000000..d06768e61 --- /dev/null +++ b/bolt/benchmarks/unstable/SlabAllocatorBenchmark.cpp @@ -0,0 +1,328 @@ +/* + * Copyright (c) ByteDance Ltd. and/or its affiliates. + * + * Licensed under the Apache License, Version 2.0 (the "License");

Its existing growth policy increases capacity aggressively, typically by 1.5x or by rounding up to a power of two. While this is appropriate for growable buffers, it can waste substantial memory when the final size is known in advance. The issue is more pronounced with jemalloc: oversized requests may be rounded up again to jemalloc size classes, compounding internal fragmentation. Introduce allocation strategies tailored to different use cases. Fixed-size buffers now use a conservative strategy that allocates only the required SIMD-aligned capacity, while growable buffers retain the existing aggressive growth strategy to reduce reallocations. This reduces internal fragmentation and lowers process RSS without compromising the performance of buffers that need to grow. --- bolt/buffer/Buffer.h | 39 +++++++++++++++---- bolt/buffer/StringViewBufferHolder.cpp | 6 ++- bolt/buffer/tests/BufferTest.cpp | 6 +-- bolt/vector/ConstantVector.cpp | 4 +- bolt/vector/FlatVector.cpp | 4 +- .../tests/VectorEstimateFlatSizeTest.cpp | 34 ++++++++-------- bolt/vector/tests/VectorTest.cpp | 4 +- 7 files changed, 63 insertions(+), 34 deletions(-) diff --git a/bolt/buffer/Buffer.h b/bolt/buffer/Buffer.h index 1c0672035..375d00de0 100644 --- a/bolt/buffer/Buffer.h +++ b/bolt/buffer/Buffer.h @@ -72,7 +72,7 @@ class Buffer { // and trivially copyable (so memcpy works) template static inline constexpr bool is_pod_like_v = - std::is_trivially_destructible_v&& std::is_trivially_copyable_v; + std::is_trivially_destructible_v && std::is_trivially_copyable_v; virtual ~Buffer() {} @@ -136,7 +136,6 @@ class Buffer { BOLT_CHECK(!isView()); BOLT_CHECK_LE(size, capacity_); size_ = size; - checkEndGuard(); } uint64_t capacity() const { @@ -330,6 +329,25 @@ class NonPODAlignedBuffer; class AlignedBuffer : public Buffer { public: + enum class AllocationStrategy { + // allocate enough memory to store the requested number of elements, + // but just strictly necessary.
