Method Detail

append

public void append(ByteBuffer record,
                   Buffer.DataType dataType)
            throws InterruptedException

Append record to HsSubpartitionMemoryDataManager.

Parameters:

record - to be managed by this class.

dataType - the type of this record. In other words, is it data or event.

Throws:

InterruptedException

getBuffersSatisfyStatus

public Deque<BufferIndexAndChannel> getBuffersSatisfyStatus(HsSpillingInfoProvider.SpillStatus spillStatus,
                                                            HsSpillingInfoProvider.ConsumeStatusWithId consumeStatusWithId)

Get buffers in allBuffers that satisfy expected HsSpillingInfoProvider.SpillStatus and HsSpillingInfoProvider.ConsumeStatus.

Parameters:

spillStatus - the status of spilling expected.

consumeStatusWithId - the status and consumerId expected.

Returns:

buffers satisfy expected status in order.

spillSubpartitionBuffers

public List<BufferWithIdentity> spillSubpartitionBuffers(List<BufferIndexAndChannel> toSpill,
                                                         CompletableFuture<Void> spillDoneFuture)

Spill this subpartition's buffers in a decision.

Parameters:

toSpill - All buffers that need to be spilled belong to this subpartition in a decision.

spillDoneFuture - completed when spill is finished.

Returns:

BufferWithIdentitys about these spill buffers.

releaseSubpartitionBuffers

public void releaseSubpartitionBuffers(List<BufferIndexAndChannel> toRelease)

Release this subpartition's buffers in a decision.

Parameters:

toRelease - All buffers that need to be released belong to this subpartition in a decision.

setOutputMetrics

public void setOutputMetrics(HsOutputMetrics outputMetrics)

registerNewConsumer

public HsSubpartitionConsumerMemoryDataManager registerNewConsumer(HsConsumerId consumerId)

releaseConsumer

public void releaseConsumer(HsConsumerId consumerId)
