Class KafkaStreamsProducer

java.lang.Object

io.quarkus.kafka.streams.runtime.KafkaStreamsProducer

@Singleton
public class KafkaStreamsProducer
extends Object

Manages the lifecycle of a Kafka Streams pipeline. If there's a producer method returning a KS Topology, then this topology will be configured and started. Optionally, before starting the pipeline, this manager will wait for a given set of topics to be created, as KS itself will fail without all input topics being created upfront.
