}

Vector index type - Flat, RaBitQ, IVF-RaBitQ, or ScaNN (IVF-PQ)

Variants

Flat(Arc<FlatVectorData>)

Flat - brute-force search over raw vectors (accumulating state)

RaBitQ(Arc<RaBitQIndex>)

RaBitQ - binary quantization, good for small datasets

IVF

IVF-RaBitQ - inverted file with RaBitQ, good for medium datasets

Fields

index: Arc<IVFRaBitQIndex>

codebook: Arc<RaBitQCodebook>

ScaNN

ScaNN (IVF-PQ) - product quantization with OPQ, best for large datasets

Fields

index: Arc<IVFPQIndex>

codebook: Arc<PQCodebook>
