If the passed sensor includes throughput metrics, e.g., when created by the StreamsMetrics.addLatencyAndThroughputSensor(String, String, String, Sensor.RecordingLevel, String...) method, then the throughput metrics will also be recorded from this event.
        Specified by:
        recordLatency in interface StreamsMetrics
        Parameters:
        sensor - sensor whose latency we are recording.
        startNs - start of measurement time in nanoseconds.
        endNs - end of measurement time in nanoseconds.

        Description copied from interface: StreamsMetrics
        Add a latency, rate and total sensor for a specific operation, which will include the following metrics:
        1. average latency
        2. max latency
        3. invocation rate (num.operations / seconds)
        4. total invocation count
        Whenever a user records this sensor via Sensor.record(double) etc, it will be counted as one invocation of the operation, and hence the rate / count metrics will be updated accordingly; and the recorded latency value will be used to update the average / max latency as well. Note that you can add more metrics to this sensor after you created it, which can then be updated upon Sensor.record(double) calls. The added sensor and its metrics can be removed with removeSensor().
        Specified by:
        addLatencyRateTotalSensor in interface StreamsMetrics
        Parameters:
        scopeName - name of the scope, which will be used as part of the metric type, e.g.: "stream-[scope]-metrics".
        entityName - name of the entity, which will be used as part of the metric tags, e.g.: "[scope]-id" = "[entity]".
        operationName - name of the operation, which will be used as the name of the metric, e.g.: "[operation]-latency-avg".
        recordingLevel - the recording level (e.g., INFO or DEBUG) for this sensor.
        tags - additional tags of the sensor
        Returns:
