Module diskann 

DiskANN: Disk-based Approximate Nearest Neighbor Search

This module provides on-disk graph-based indexing for handling datasets too large to fit in memory (100M+ vectors).

Key features:

• Memory-mapped graph access for constant memory usage
• Vamana algorithm for efficient graph construction
• Page cache optimization for fast queries
• Index compaction and optimization
