Module auto_index 

Auto-Index Selection

Automatically selects the optimal index type based on data characteristics:

• Dataset size (number of vectors)
• Dimensionality
• Memory constraints
• Query latency requirements
• Accuracy requirements

Index Selection Matrix

Vectors	Dimensions	Memory	Latency	Recommended Index
< 10K	Any	Any	Any	Flat (brute force)
10K-100K	< 256	Low	Medium	IVF + SQ8
10K-100K	< 256	Normal	Low	HNSW
100K-1M	Any	Low	Medium	IVF-PQ
100K-1M	Any	Normal	Low	HNSW
> 1M	Any	Low	Any	IVF-PQ
> 1M	Any	Normal	Low	HNSW + SQ8
