We are pleased to announce the release of GraphAr Version 0.2.0! This release includes a number of new features and performance improvements to the GraphAr libraries, as well as addressing some project-related issues.

The main improvements included in this release are:

  1. Optimizing the GraphAr Spark library:
  • Implement a custom data source for GraphAr to improve the performance of the GraphAr Spark Reader/Writer.
  • Fix the Spark Writer bug when the column name contains a dot (.).
  1. Including more methods in the libraries:
  • Provide more reading methods in the Spark library for convenience.
  • Add auxiliary functions in the C++ library to get vertex chunk number or edge chunk number with infos.
  1. Addressing some issues when using GraphAr in external projects:
  • Handle yaml-cpp correctly when requiring GraphAr in external projects.
  • Use gar-related names for arrow project and ccache to avoid duplicated project names.
  • Use linker flags to suppress the clang warnings.
  • Add prefix to arrow definitions to avoid conflicts.
  • Cast StringArray to LargeStringArray in Arrow for generality.
  1. Improving the project configurations and other bug fixes:
  • Add pre-commit configuration and instructions.
  • Handle comments correctly for preview PR docs.
  • Write CSV payload files with header.
  • Update the source code url of GraphScope fragment builder and writer.
