> > Hi,@acezen @jasinliu. This should solve the problem in #628, please review this. > > Thanks! I think you can create some tests following #628 . Or you can provide the verification process through comments. Yes, I used the totally same exmaple in the comment for testing and the installation steps are exactly the same, the results show that we can run this code correctly <img width="723" alt="image" src="https://github.com/user-attachments/assets/a62a5c7e-64e1-4696-afa1-17e089ab08ba";> ## Other example ### test_read.cc ``` cpp #include <cstdlib> #include <iostream> #include "arrow/api.h" #include "graphar/api/arrow_reader.h" int main() { std::string path = "/workspaces/incubator-graphar/testing/ldbc_sample/parquet/ldbc_sample.graph.yml"; std::string src_type = "person", edge_type = "knows", dst_type = "person"; std::string vertex_property_name = "id"; std::string edge_property_name = "creationDate"; auto maybe_graph_info = graphar::GraphInfo::Load(path); auto graph_info = maybe_graph_info.value(); auto vertex_info = graph_info->GetVertexInfo(src_type); auto maybe_reader = graphar::VertexPropertyArrowChunkReader::Make( graph_info, src_type, vertex_property_name); auto reader = maybe_reader.value(); std::cout << "Chunknum " << reader->GetChunkNum() << std::endl; auto result = reader->GetChunk(); auto table = result.value(); std::cout << "num_rows " << table->num_rows() << std::endl; } ``` ### CMakeLists.txt ```cmake cmake_minimum_required(VERSION 3.15) project(test_read) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -Wall") set(TARGET test_read) # find_package(OpenSSL REQUIRED) find_package(graphar REQUIRED) find_package(Arrow REQUIRED) add_executable(${TARGET} test_read.cc) target_link_libraries(${TARGET} PRIVATE graphar Arrow::arrow_static) ``` ### build ```shell cmake . && make ``` <img width="738" alt="image" src="https://github.com/user-attachments/assets/bed9478f-b567-4d9f-b973-2cbe1f5cdae3";> -- This is an automated message from the Apache Git Service.
