Inputs to the cost model.

Fields

n_vectors: usize

Total number of vectors in the collection.

dim: usize

Embedding dimension.

index_type: IndexType

Which graph index will be used.

quantization: QuantizationKind

Which quantization codec will be used during traversal.

ef_search: usize

Beam width.

global_selectivity: f32

Global filter selectivity in [0.0, 1.0]. 1.0 means no filter (all vectors are candidates).

candidate_set_size: usize

Expected candidate set size after applying filters. Typically (n_vectors as f32 * global_selectivity) as usize.
