• Large-scale vector dataset support, suitable for production-scale search workloads.
• Multi-language support:
  • Python bindings
  • Java bindings
  • Core C++ implementation (in cpp directory)
• Library and service modes:
  • Usable as a library within Python/Java applications
  • Can be deployed as a standalone service for vector search
• Performance and benchmarking:
  • Dedicated benchmarks directory for performance tests and comparisons
  • Designed for efficient query performance on large indexes
• Documentation:
  • docs directory with project documentation and usage guidance
• Project governance and contribution:
  • CODE_OF_CONDUCT.md defining contributor behavior
  • CONTRIBUTING.md with contribution guidelines
  • OWNERS.md documenting project ownership/maintainers
