  • Method Details

    • consume

      void consume(Runnable signalsInterrupt)
      Consume **must** make sure that interrupted status is restored as it is needed for stopping unhealthy consumers. Swallowing the interrupt by consume or any of its dependencies will result in consumer being marked as unhealthy and will prevent commits despite messages being sent to subscribers.
