Adding batch support for Redis stream listener containers

[MrPickle311]

A good option in Redis stream processing would be adding a batch processing feature. It can improve performance and comfort using Stream API for Spring Data Redis.

For example new/extended interface can look like this.

@FunctionalInterface
public interface BatchStreamListener<K, V extends Record<K, ?>> {

	void onMessage(List<V> message);

}

example usage:

public class  SomeService {

       private final SomeJpaRepository someJpaRepository;
       private final StreamMessageListenerContainer container;

	void someMethod() {
                StreamReadRequest<String> readRequest = ...;
                container.registerBatch(readRequest, messages -> {
                          List<SomeEntity> result =  someJpaRepository.findAllById(messages.map(SomeRecord:::getId).toList());
                          processResult(result);
                });
        }

}
