All Implemented Interfaces:

reactor.kafka.receiver.KafkaReceiver<K,V>

public class TracingKafkaReceiver<K,V>
extends Object
implements reactor.kafka.receiver.KafkaReceiver<K,V>

Constructor Detail

TracingKafkaReceiver

public TracingKafkaReceiver(ReactiveKafkaTracingPropagator reactiveKafkaTracingPropagator,
                            reactor.kafka.receiver.KafkaReceiver<K,V> delegate)

Method Detail

create

public static <K,V> reactor.kafka.receiver.KafkaReceiver<K,V> create(ReactiveKafkaTracingPropagator reactiveKafkaTracingPropagator,
                                                                     reactor.kafka.receiver.ReceiverOptions<K,V> options)

Creates KafkaReceiver that will de decorated by tracing propagator to provide kafka consumer publishing elements containing tracing context in their reactor context.

Type Parameters:

K - Key of the record

V - Value of the record

Parameters:
