Method Detail

startTrackingPartition

void startTrackingPartition(org.apache.flink.api.common.JobID producingJobId,
                            TaskExecutorPartitionInfo partitionInfo)

Starts the tracking of the given partition for the given job.

Parameters:

producingJobId - ID of job by which the partition is produced

partitionInfo - information about the partition

stopTrackingAndReleaseJobPartitions

void stopTrackingAndReleaseJobPartitions(Collection<ResultPartitionID> resultPartitionIds)

Releases the given partitions and stop the tracking of partitions that were released.

stopTrackingAndReleaseJobPartitionsFor

void stopTrackingAndReleaseJobPartitionsFor(org.apache.flink.api.common.JobID producingJobId)

Releases all partitions for the given job and stop the tracking of partitions that were released.

getTrackedPartitionsFor

Collection<TaskExecutorPartitionInfo> getTrackedPartitionsFor(org.apache.flink.api.common.JobID producingJobId)

Get all partitions tracked for the given job.

Parameters:

producingJobId - the job id

Returns:

the tracked partitions

promoteJobPartitions

void promoteJobPartitions(Collection<ResultPartitionID> partitionsToPromote)

Promotes the given partitions.

stopTrackingAndReleaseClusterPartitions

void stopTrackingAndReleaseClusterPartitions(Collection<IntermediateDataSetID> dataSetsToRelease)

Releases partitions associated with the given datasets and stops tracking of partitions that were released.

Parameters:

dataSetsToRelease - data sets to release

stopTrackingAndReleaseAllClusterPartitions

void stopTrackingAndReleaseAllClusterPartitions()
