DiskTierConsumerAgent

public DiskTierConsumerAgent(List<TieredStorageConsumerSpec> tieredStorageConsumerSpecs,
                             TieredStorageNettyService nettyService)

方法详细资料

setup

public void setup(TieredStorageMemoryManager memoryManager)

从接口复制的说明: TierConsumerAgent

The consumer agent may request buffers from the memory manager. Therefore, the TieredStorageMemoryManager should be integrated into the tier consumer agent. Since the buffer pool is initialized after the creation of the client, the memory manager need to be assigned after the buffer pool becomes available.

指定者:

setup 在接口中 TierConsumerAgent

start

public void start()

从接口复制的说明: TierConsumerAgent

Start the consumer agent.

指定者:

start 在接口中 TierConsumerAgent

registerAvailabilityNotifier

public void registerAvailabilityNotifier(AvailabilityNotifier notifier)

从接口复制的说明: TierConsumerAgent

Register the notifier to notify the availability of a subpartition.

指定者:

registerAvailabilityNotifier 在接口中 TierConsumerAgent

参数:

notifier - to notify availability.

updateTierShuffleDescriptor

public void updateTierShuffleDescriptor(TieredStoragePartitionId partitionId,
                                        TieredStorageInputChannelId inputChannelId,
                                        TieredStorageSubpartitionId subpartitionId,
                                        TierShuffleDescriptor tierShuffleDescriptor)

从接口复制的说明: TierConsumerAgent

Update the TierShuffleDescriptor for the consumer agent.

指定者:

updateTierShuffleDescriptor 在接口中 TierConsumerAgent

peekNextBufferSubpartitionId

public int peekNextBufferSubpartitionId(TieredStoragePartitionId partitionId,
                                        ResultSubpartitionIndexSet indexSet)
                                 throws IOException

从接口复制的说明: TierConsumerAgent

Returns the index of the subpartition where the next buffer locates, or -1 if there is no buffer available or the subpartition index does not belong to the specified indexSet.

指定者:

peekNextBufferSubpartitionId 在接口中 TierConsumerAgent

参数:

partitionId - The index of the partition which the returned subpartition should belong to.

indexSet - The indexes of the subpartitions expected.

抛出:

IOException

getNextBuffer

public Optional<Buffer> getNextBuffer(TieredStoragePartitionId partitionId,
                                      TieredStorageSubpartitionId subpartitionId,
                                      int segmentId)

从接口复制的说明: TierConsumerAgent

Get buffer from the consumer agent.

指定者:

getNextBuffer 在接口中 TierConsumerAgent

参数:

partitionId - the id of partition.

subpartitionId - the id of subpartition.

segmentId - the id of segment.

返回:

buffer.

close

public void close()
           throws IOException

从接口复制的说明: TierConsumerAgent

Close the consumer agent.

指定者:

close 在接口中 TierConsumerAgent

抛出:

IOException
