A Redis stream is a data structure that acts like an append-only log.

You can use streams to record and simultaneously syndicate events in real time

@Configuration
public class RedisConfig {

	@Value("${stream.key}")
	private String streamKey;

	@Autowired
	private StreamListener<String, ObjectRecord<String, MovieDetails>> streamListener;


	@Bean
	public Subscription subscription(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
		StreamMessageListenerContainer.StreamMessageListenerContainerOptions<String, ObjectRecord<String, MovieDetails>> options = StreamMessageListenerContainer
				.StreamMessageListenerContainerOptions
				.builder()
				.pollTimeout(Duration.ofSeconds(1))
				.targetType(MovieDetails.class)
				.build();
		StreamMessageListenerContainer<String, ObjectRecord<String, MovieDetails>>  listenerContainer = StreamMessageListenerContainer
				.create(redisConnectionFactory, options);
		Subscription subscription = listenerContainer.receive(
				Consumer.from(streamKey, InetAddress.getLocalHost()
				                                    .getHostName()),
				StreamOffset.create(streamKey, ReadOffset.lastConsumed()),
				streamListener);
		listenerContainer.start();
		return subscription;
	}
}
