TODO:

  • In memory vamana based on current segments
  • Vamana index with filtering
  • Vamana index with deletion
  • Optimize filtering algorithm

Discussions:

  • Current vamana index implementation use full precision building and searching, as current segments implementation is different from diskANN storage method, how to gradually build full-precision index stored in segments and using quantization to do the construction and searching process?

  • performance and precision
