Annotation Interface Vector

@Target(FIELD)
@Retention(RUNTIME)
public @interface Vector

Annotation to mark a field as a vector in a collection document.

This annotation indicates that the field should be serialized with the special property name "$vector" for use with DataStax Astra DB's vector search features. The field must be of type float[] or DataAPIVector.

Example usage:

 
 @DataApiCollection
 public class MyDocument {
     @DocumentId
     private String id;
     
     @Vector
     private float[] embedding;
     
     // or
     
     @Vector
     private DataAPIVector embedding;
     
     // getters and setters
 }
