@Target(TYPE) @Retention(RUNTIME) public @interface TablePrimaryKeyClass

Marks a class as representing a composite primary key for a table entity.

This annotation is used to define a separate class that encapsulates the primary key components (partition key + clustering columns) of a table. Fields within this class should be annotated with PartitionBy and PartitionSort to define the key structure.

This pattern is similar to Spring Data Cassandra's @PrimaryKeyClass and allows for cleaner entity modeling when dealing with composite keys.

Usage Example:

 
 @TablePrimaryKeyClass
 public class OrderKey {
     @PartitionBy(1)
     @Column("customer_id")
     private String customerId;
     
     @PartitionSort(position = 1, order = PartitionSortOrder.ASC)
     @Column("order_date")
     private LocalDate orderDate;
     
     // constructors, getters, setters, equals, hashCode
 }

 @EntityTable("orders")
 public class Order {
     @TablePrimaryKey
     private OrderKey key;
     
     @Column("amount")
     private BigDecimal amount;
     
     // getters and setters
 }

Retention: RUNTIME

This annotation is retained at runtime to allow runtime reflection.

Target: TYPE

This annotation can only be applied to classes.
