v0.28.0

Higtlights:

• support for the new "vector of float" (FLOATA) data type
• new scalar functions cosine_similarity, euclidean_distance and dot_product
• Upgrade BookKeeper to 4.16.3

See #812

Sample table:

CREATE TABLE DOCUMENTS (
            FILENAME string
            CHUNKID int, "
            TEXT string, "
             EMBEDDINGSVECTOR floata,
             PRIMARY KEY(filename, chinkid)
)

Sample Vector Search query

SELECT text
FROM DOCUMENTS
ORDER BY cosine_similarity(embeddingsvector,cast(? as FLOAT ARRAY)) DESC
LIMIT 10
