Interface ReactiveValueOperations<K,V>

public interface ReactiveValueOperations<K,V>
Reactive Redis operations for simple (or in Redis terminology 'string') values.

Streams of methods returning Mono<K> or Flux<M> are terminated with InvalidDataAccessApiUsageException when RedisElementReader.read(ByteBuffer) returns null for a particular element as Reactive Streams prohibit the usage of null values.
