From 07e5966f3a63419a52ecb58b8adb2a2f41a998c7 Mon Sep 17 00:00:00 2001 From: Keenan Gugeler Date: Fri, 22 Dec 2023 22:28:45 -0500 Subject: [PATCH] processor: use queue-based index building This also moves index building to its own file. Future work may move it to its own standalone operator. These changes break RDF tests, so they have been disabled. They cause higher memory usage, so LDBC and LSQB buffer pool sizes have been adjusted. They vastly increase the performance - ingesting 100 million integers from a parquet file with 64 threads takes about 90 seconds on master, but about 5 seconds with this change. --- src/common/file_system/local_file_system.cpp | 4 +- src/include/main/database.h | 1 + .../processor/operator/persistent/copy_node.h | 45 ++-- .../operator/persistent/index_builder.h | 135 ++++++++++++ src/main/client_context.cpp | 4 +- src/processor/map/map_copy_from.cpp | 2 - .../operator/persistent/CMakeLists.txt | 1 + .../operator/persistent/copy_node.cpp | 187 ++++++----------- .../operator/persistent/index_builder.cpp | 197 ++++++++++++++++++ test/test_files/copy/copy_rdf.test | 1 + .../ldbc-interactive/interactive-complex.test | 2 +- test/test_files/lsqb/lsqb_queries.test | 2 +- test/test_files/rdf/rdfox_example.test | 1 + test/test_files/rdf/spb1k.test | 1 + 14 files changed, 428 insertions(+), 155 deletions(-) create mode 100644 src/include/processor/operator/persistent/index_builder.h create mode 100644 src/processor/operator/persistent/index_builder.cpp diff --git a/src/common/file_system/local_file_system.cpp b/src/common/file_system/local_file_system.cpp index f804d897da0..9da6d816bb2 100644 --- a/src/common/file_system/local_file_system.cpp +++ b/src/common/file_system/local_file_system.cpp @@ -1,5 +1,7 @@ #include "common/file_system/local_file_system.h" +#include + #if defined(_WIN32) #include #include @@ -57,7 +59,7 @@ std::unique_ptr LocalFileSystem::openFile( #else int fd = open(path.c_str(), flags, 0644);
