Method Detail

create

public static KafkaTracing create(brave.Tracing tracing)

newBuilder

public static KafkaTracing.Builder newBuilder(brave.Tracing tracing)

consumer

public <K,V> org.apache.kafka.clients.consumer.Consumer<K,V> consumer(org.apache.kafka.clients.consumer.Consumer<K,V> consumer)

Extracts or creates a Span.Kind.CONSUMER span for each message received. This span is injected onto each message so it becomes the parent when a processor later calls nextSpan(ConsumerRecord).

producer

public <K,V> org.apache.kafka.clients.producer.Producer<K,V> producer(org.apache.kafka.clients.producer.Producer<K,V> producer)

Starts and propagates Span.Kind.PRODUCER span for each message sent.

nextSpan

public brave.Span nextSpan(org.apache.kafka.clients.consumer.ConsumerRecord<?,?> record)

Use this to create a span for processing the given record. Note: the result has no name and is not started.

This creates a child from identifiers extracted from the record headers, or a new span if one couldn't be extracted.
