Package org.springframework.data.redis.core.script

Interface ReactiveScriptExecutor<K>

Type Parameters:
K - The type of keys that may be passed during script execution
All Known Implementing Classes:
DefaultReactiveScriptExecutor
public interface ReactiveScriptExecutor<K>
Executes RedisScripts using reactive infrastructure.

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.
