Example 1 with Propagation

use of brave.propagation.Propagation in project brave by openzipkin.

the class ITKafkaTracing method continues_a_trace_when_only_trace_id_propagated.

@Test
public void continues_a_trace_when_only_trace_id_propagated() throws Exception {
    consumerTracing = KafkaTracing.create(Tracing.newBuilder().spanReporter(consumerSpans::add).propagationFactory(new Propagation.Factory() {

        @Override
        public <K> Propagation<K> create(Propagation.KeyFactory<K> keyFactory) {
            return new TraceIdOnlyPropagation<>(keyFactory);
        }

    producerTracing = KafkaTracing.create(Tracing.newBuilder().spanReporter(producerSpans::add).propagationFactory(new Propagation.Factory() {

        @Override

    }).sampler(Sampler.ALWAYS_SAMPLE).build());
    producer = createTracingProducer();

}

Example 2 with Propagation

        @Override
        public <K> Propagation<K> create(Propagation.KeyFactory<K> keyFactory) {
