Index files for backward compatibility testing

This release stores index files generated by different VSAG versions for compatibility testing.

Files

• random_512d_10K.bin - Shared test dataset (20 MB)
• {version}_{algo}.index - Index files for each version
• {version}_{algo}_build.json - Build configuration
• {version}_{algo}_search.json - Search configuration

Usage

These files are automatically downloaded by CI workflows for compatibility testing.

Update

New index files are automatically uploaded when a new version is released.
