DISTANCE() and VECTOR_DISTANCE(): Vector Similarity in Percona Server for MySQL 9.7

Percona Server for MySQL 9.7.2-2 adds the DISTANCE() function for scoring vector similarity directly in SQL, with COSINE, EUCLIDEAN, MANHATTAN, and DOT metrics. The function supplies the scoring layer for vector comparisons, while ANN indexing such as HNSW or IVF is identified as a later milestone for fast large-scale search.
