| 限定符和类型 | 方法和说明 |
|---|---|
void |
acknowledgeAllRecordsProcessed()
When received
EndOfData from one channel, it need to acknowledge after this event get
processed. |
void |
checkpointStarted(CheckpointBarrier barrier)
Called by task thread when checkpointing is started (e.g., any input channel received
barrier).
|
void |
checkpointStopped(long checkpointId)
Called by task thread on cancel/complete to clean-up temporary data.
|
void |
notifyDataAvailable()
Called whenever there might be new data available.
|
protected void |
requestSubpartition()
Requests the subpartition specified by
InputChannel.partitionId and InputChannel.consumedSubpartitionIndex. |
void |
resumeConsumption()
After sending a
CheckpointBarrier of
exactly-once mode, the upstream will be blocked and become unavailable. |
