You can connect a trigger to a sink, so that events from a broker are filtered before they are sent to the sink. A sink that is connected to a trigger is configured as a subscriber in the Trigger object’s resource spec.

Example of a Trigger object connected to an Apache Kafka sink
apiVersion: eventing.knative.dev/v1
kind: Trigger
  name: <trigger_name> (1)
      apiVersion: eventing.knative.dev/v1alpha1
      kind: KafkaSink
      name: <kafka_sink_name> (2)
1 The name of the trigger being connected to the sink.
2 The name of a KafkaSink object.
