Interface ReactiveSetOperations<K,V>

public interface ReactiveSetOperations<K,V>
Reactive Redis operations for Set Commands.

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.
