numOfPartitions

protected final int numOfPartitions

numOfSubpartitions

protected final int numOfSubpartitions

subpartitionBytesByPartitionIndex

protected final Map<Integer,long[]> subpartitionBytesByPartitionIndex

The subpartition bytes map. The key is the partition index, value is a subpartition bytes list.

方法详细资料

isBroadcast

public boolean isBroadcast()

从接口复制的说明: IntermediateResultInfo

Whether it is a broadcast result.

返回:

whether it is a broadcast result

isPointwise

public boolean isPointwise()

从接口复制的说明: IntermediateResultInfo

Whether it is a pointwise result.

返回:

whether it is a pointwise result

getNumPartitions

public int getNumPartitions()

从接口复制的说明: IntermediateResultInfo

Get number of partitions for this result.

返回:

the number of partitions in this result

getNumSubpartitions

public int getNumSubpartitions(int partitionIndex)

从接口复制的说明: IntermediateResultInfo

Get number of subpartitions for the given partition.

参数:

partitionIndex - the partition index

返回:

the number of subpartitions of the partition

getNumBytesProduced

public long getNumBytesProduced()

从接口复制的说明: BlockingResultInfo

Return the num of bytes produced(numBytesProduced) by the producer.

The difference between numBytesProduced and numBytesOut : numBytesProduced represents the number of bytes actually produced, and numBytesOut represents the number of bytes sent to downstream tasks. In unicast scenarios, these two values should be equal. In broadcast scenarios, numBytesOut should be (N * numBytesProduced), where N refers to the number of subpartitions.

返回:

the num of bytes produced by the producer

getNumBytesProduced

public long getNumBytesProduced(IndexRange partitionIndexRange,
                                IndexRange subpartitionIndexRange)

从接口复制的说明: BlockingResultInfo

Return the aggregated num of bytes according to the index range for partition and subpartition.

参数:

partitionIndexRange - range of the index of the consumed partition.

subpartitionIndexRange - range of the index of the consumed subpartition.

返回:

aggregated bytes according to the index ranges.

recordPartitionInfo

public void recordPartitionInfo(int partitionIndex,
                                ResultPartitionBytes partitionBytes)

从接口复制的说明: BlockingResultInfo

Record the information of the result partition.

指定者:

recordPartitionInfo 在接口中 BlockingResultInfo

参数:

partitionIndex - the intermediate result partition index

partitionBytes - the ResultPartitionBytes of the partition

resetPartitionInfo

public void resetPartitionInfo(int partitionIndex)

从接口复制的说明: BlockingResultInfo

Reset the information of the result partition.

指定者:

resetPartitionInfo 在接口中 BlockingResultInfo

参数:

partitionIndex - the intermediate result partition index

getAggregatedSubpartitionBytes

public List<Long> getAggregatedSubpartitionBytes()

getResultId

public IntermediateDataSetID getResultId()

从接口复制的说明: IntermediateResultInfo

Get the intermediate result id.

指定者:

getResultId 在接口中 IntermediateResultInfo

返回:

the intermediate result id
