所有已实现的接口:

ChannelStateHolder, CheckpointedResultSubpartition

public class PipelinedApproximateSubpartition
extends PipelinedSubpartition

A pipelined in-memory only subpartition, which allows to reconnecting after failure. Only one view is allowed at a time to read teh subpartition.

createReadView

public PipelinedSubpartitionView createReadView(BufferAvailabilityListener availabilityListener)

To simply the view releasing threading model, releaseView() is called only before creating a new view.

There is still one corner case when a downstream task fails continuously in a short period of time then multiple netty worker threads can createReadView at the same time. TODO: This problem will be solved in FLINK-19774

覆盖:

createReadView 在类中 PipelinedSubpartition

finishReadRecoveredState

public void finishReadRecoveredState(boolean notifyAndBlockOnCompletion)
                              throws IOException

指定者:

finishReadRecoveredState 在接口中 CheckpointedResultSubpartition

覆盖:

finishReadRecoveredState 在类中 PipelinedSubpartition

抛出:

IOException
