ThroughputCalculator

public ThroughputCalculator(org.apache.flink.util.clock.Clock clock,
                            int numberOfSamples)

方法详细资料

incomingDataSize

public void incomingDataSize(long receivedDataSize)

pauseMeasurement

public void pauseMeasurement(long absoluteTimeMillis)

Mark when the time should not be taken into account.

参数:

absoluteTimeMillis - Current absolute time received outside to avoid performance drop on calling Clock.absoluteTimeMillis() inside of the method.

resumeMeasurement

public void resumeMeasurement(long absoluteTimeMillis)

Mark when the time should be included to the throughput calculation.

参数:

absoluteTimeMillis - Current absolute time received outside to avoid performance drop on calling Clock.absoluteTimeMillis() inside of the method.

calculateThroughput

public long calculateThroughput()
