You can perform vector similarity search using the now Generally Available K-nearest neighbors (KNN) vector distance functions

## Feature You can perform vector similarity search using the now Generally Available K-nearest neighbors (KNN) vector distance functions: * `COSINE_DISTANCE()` * `EUCLIDEAN_DISTANCE()` * `DOT_PRODUCT()` For more information, see [Perform vector similarity search in Spanner by finding the K-nearest neighbors](https://cloud.google.com/spanner/docs/find-k-nearest-neighbors). ## Feature The `FLOAT32` ([GoogleSQL](https://cloud.google.com/spanner/docs/reference/standard-sql/data-types#floating%5Fpoint%5Ftypes)) and `float4/real` ([PostgreSQL](https://cloud.google.com/spanner/docs/reference/postgresql/data-types#supported)) data types are Generally Available.
