    • getStream

      @ManagedAttribute(description="Name of the stream channel used by the endpoint to exchange messages") public String getStream()

    • setStream

      public void setStream(String stream)
      Name of the stream channel used by the endpoint to exchange messages.

    • getMaxInflightExchanges

      @ManagedAttribute(description="Maximum number of exchanges concurrently being processed by Camel") public Integer getMaxInflightExchanges()

    • setMaxInflightExchanges

      public void setMaxInflightExchanges(Integer maxInflightExchanges)
      Maximum number of exchanges concurrently being processed by Camel. This parameter controls backpressure on the stream. Setting a non-positive value will disable backpressure.

    • getConcurrentConsumers

      public int getConcurrentConsumers()

    • setConcurrentConsumers

      @ManagedAttribute(description="Number of threads used to process exchanges in the Camel route") public void setConcurrentConsumers(int concurrentConsumers)
      Number of threads used to process exchanges in the Camel route.

    • getBackpressureStrategy

      public ReactiveStreamsBackpressureStrategy getBackpressureStrategy()

    • setBackpressureStrategy

      public void setBackpressureStrategy(ReactiveStreamsBackpressureStrategy backpressureStrategy)
      The backpressure strategy to use when pushing events to a slow subscriber.

    • isForwardOnComplete

      @ManagedAttribute(description="Determines if onComplete events should be pushed to the Camel route") public boolean isForwardOnComplete()

    • setForwardOnComplete

      public void setForwardOnComplete(boolean forwardOnComplete)
      Determines if onComplete events should be pushed to the Camel route.

    • isForwardOnError

      @ManagedAttribute(description="Determines if onError events should be pushed to the Camel route") public boolean isForwardOnError()

    • setForwardOnError

      public void setForwardOnError(boolean forwardOnError)
      Determines if onError events should be pushed to the Camel route. Exceptions will be set as message body.

    • getExchangesRefillLowWatermark

      @ManagedAttribute(description="The percentage of maxInflightExchanges below which new items can be requested to the source subscription") public double getExchangesRefillLowWatermark()

    • setExchangesRefillLowWatermark

      public void setExchangesRefillLowWatermark(double exchangesRefillLowWatermark)
      Set the low watermark of requested exchanges to the active subscription as percentage of the maxInflightExchanges. When the number of pending items from the upstream source is lower than the watermark, new items can be requested to the subscription. If set to 0, the subscriber will request items in batches of maxInflightExchanges, only after all items of the previous batch have been processed. If set to 1, the subscriber can request a new item each time an exchange is processed (chatty). Any intermediate value can be used.
