@Consistency annotation results in Kotlin compilation error [DATACASS-797]

Gautam Jolly opened DATACASS-797 and commented

Compilation of a Kotlin function, that is annotated with @Consistency, results in compilation error “An annotation argument must be a compile-time constant”. Note that fhis feature worked well in spring-data-cassandra-2.1.X.

@Consistency(DefaultConsistencyLevel.QUORUM)
fun doSomething()

The equivalent Java code works just fine:

@Consistency(DefaultConsistencyLevel.QUORUM)
public void doSomething();

To workaround this issue:

1. We created an annotation, which is meta-annotated with \@Consistency, in Java

@Documented
@Target({ElementType.ANNOTATION_TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Consistency(DefaultConsistencyLevel.QUORUM)
public @interface QuorumConsistency {}

1. Applied the newly created annotation to the Kotlin function

@QuorumConsistency //@Consistency(DefaultConsistencyLevel.QUORUM)
fun doSomething()

According to the Cassandra driver team, they intend to address the issue on their side. Closing this ticket until further notice
