### Vector Functions

- `cosine_similarity(x,y)` -> number
- `l2distance(x,y)` -> number
- `l2normalize(x)` -> Vector
- `vector_embedding(field, kind?, model?)` -> Vector

For `vector_embedding`, `kind` defaults to `'DOCUMENT'` and `model` to `'SAP_GXY.20250407'`; use the `vectorEmbeddingDefaultModel` and `vectorEmbeddingHanaDefaultRemoteSource` compiler options to change these defaults.

> [!warning] HANA and PostgreSQL only
> Vector functions require SAP HANA Cloud or PostgreSQL with [pgvector](https://github.com/pgvector/pgvector).

I think for Java it works on HANA, PG, SQLite and H2 and on PG vector_embedding will not work.
