Annotation Interface PrimaryKey

@Documented
@Retention(RUNTIME)
@Target({ANNOTATION_TYPE,FIELD,METHOD})
@Column
public @interface PrimaryKey

Identifies the primary key field of the entity, which may be of a basic type or of a type that represents a composite primary key class. This field corresponds to the PRIMARY KEY of the corresponding Cassandra table. Only one field in a given type hierarchy may be annotated with this annotation.

Remember, if the Cassandra table has multiple primary key columns, then you must define a class annotated with PrimaryKeyClass to represent the primary key!

Use PrimaryKeyColumn in conjunction with Id to specify extended primary key column properties.
