Method Detail

createSqlStage

public static SqlStage createSqlStage(StageId stageId,
                                      PlanFragment fragment,
                                      Map<PlanNodeId,TableInfo> tables,
                                      RemoteTaskFactory remoteTaskFactory,
                                      Session session,
                                      boolean summarizeTaskInfo,
                                      NodeTaskMap nodeTaskMap,
                                      Executor executor,
                                      SplitSchedulerStats schedulerStats)

getStageId

public StageId getStageId()

finish

public void finish()

abort

public void abort()

fail

public void fail(Throwable throwable)

addFinalStageInfoListener

public void addFinalStageInfoListener(StateMachine.StateChangeListener<StageInfo> stateChangeListener)

Add a listener for the final stage info. This notification is guaranteed to be fired only once. Listener is always notified asynchronously using a dedicated notification thread pool so, care should be taken to avoid leaking this when adding a listener in a constructor. Additionally, it is possible notifications are observed out of order due to the asynchronous execution.

getFragment

public PlanFragment getFragment()

getUserMemoryReservation

public long getUserMemoryReservation()

getTotalMemoryReservation

public long getTotalMemoryReservation()

getTotalCpuTime

public io.airlift.units.Duration getTotalCpuTime()

getBasicStageStats

public BasicStageStats getBasicStageStats()

getStageInfo

public StageInfo getStageInfo()

createTask

public Optional<RemoteTask> createTask(InternalNode node,
                                       int partition,

                                       Optional<int[]> bucketToPartition,
                                       OutputBuffers outputBuffers,
                                       com.google.common.collect.Multimap<PlanNodeId,Split> splits,
