cap-embedding-function

A CAP service that computes a note's Vector(768) embedding in its own handlers, selecting SAP HANA CloudSAP HANA CloudserviceThe managed database under most of this: CAP's default target, the store Datasphere and Analytics Cloud sit on, and a service with plans and components.sap official, btp's vector_embedding as a column from a Dummy entity.

Notes carries a Vector(768) element and is projected to the service without it; before-CREATE and before-UPDATE handlers fill it from vector_embedding(${text}, 'DOCUMENT', 'SAP_NEB.20240715'), selected as a column from the Dummy entity at id: 1. The similaritySearch function embeds the search word the same way and returns three notes with their cosine_similarity against to_real_vector of that embedding, ordered descending. cap-vector-hccap-vector-hcsampleA sample that declares VECTOR_EMBEDDING in a CDS entity: an FAQ model whose embedding column HANA Cloud generates and stores, then answers questions by similarity search.independent, cap declares the embedding on the element and lets HANA Cloud generate and store it; here the handler owns both the write and the query. The project sets cds.requires to db: hana and auth: dummy, depends on @cap-js/hana@cap-js/hanacds-pluginThe HANA database service — the production default, on the same streamlined architecture as the SQLite and PostgreSQL services.sap official, cap, and its README is the CAP scaffold's own getting-started text.
