Used for semantically finding courses, holding embedding vectors
| Name | Type | Default | Nullable | Children | Parents | Comment |
|---|---|---|---|---|---|---|
| course_id | uuid | false | public.courses | Embeddings belong to a specific course. | ||
| created_at | timestamp with time zone | now() | false | Timestamp when the record was created. | ||
| deleted_at | timestamp with time zone | true | Timestamp when the record was deleted. If null, the record is not deleted. | |||
| description_embedding | vector(1536) | true | Embedding vector of the course description. | |||
| id | uuid | uuid_generate_v4() | false | A unique, stable identifier for the record. | ||
| title_embedding | vector(1536) | true | Embedding vector of the course title. | |||
| updated_at | timestamp with time zone | now() | false | Timestamp when the record was last updated. The field is updated automatically by the set_timestamp trigger. |
