Vector Operations

Helpers for vector similarity search and distance computation

Functions

compute_vector_distances

Compute vector distance for an array of vectors against a single query vector

compute_vector_similarities

Compute vector similarities for an array of vectors against a single query vector

cosine_distance

Compute cosine distance (1 - cosine_similarity) between two vectors Returns a value in [0, 2] where 0 means identical and 2 means opposite

cosine_similarity

Compute cosine similarity (for vector_similarity function) Returns a value in [-1, 1] where 1 means identical and -1 means opposite

dot_product_distance

Compute dot product between two vectors For similarity search, we return the negative (so lower is better for sorting)

dot_product_similarity

Compute dot product similarity (for vector_similarity function)

extract_single_vector_from_scalar

Extract a single vector from a ScalarValue This avoids allocating a full array when we just need one vector

extract_vectors

Extract vectors from Arrow ListArray or FixedSizeListArray

l2_distance

Compute L2 (Euclidean) distance between two vectors
