sqlite_plus_vec 0.1.0

Brute-force vec0 vector search for sqlite_plus, with ORM nearest queries.

Changelog

0.1.0

Depends on sqlite_plus 0.1.6. Brute-force vec0 virtual table for one little-endian float32 column.

• SqlitePlusVec.register accepts a SqliteDatabase, a MutableSqliteDatabase, or the connection's SqlFunctionRegistry.
• CREATE VIRTUAL TABLE ... USING vec0(embedding float[N] distance_metric=l2|cosine) scans every row for embedding MATCH ? AND k = ?.
• vecDistance, encodeVec, and decodeVec are the same float32 math. Dimensions are 1 to 4096. k is 1 to 100000.
• An ORM table uses DbModules.vec0 and @DbVector. nearest returns the k closest rows.
• The scan is not an approximate index. The file is not a sqlite-vec database.
