public VersionedMemoryPoolId getMemoryPool()

Specified by:

getMemoryPool in interface QueryExecution

setMemoryPool

public void setMemoryPool(VersionedMemoryPoolId poolId)

Specified by:

setMemoryPool in interface QueryExecution

getSession

public Session getSession()

getSession in interface QueryTracker.TrackedQuery

getErrorCode

public Optional<ErrorCode> getErrorCode()

Specified by:

getErrorCode in interface ManagedQueryExecution

Returns:

Returns non-empty value iff error has occurred and query failed state is visible.

getUserMemoryReservation

public io.airlift.units.DataSize getUserMemoryReservation()

Specified by:

getUserMemoryReservation in interface ManagedQueryExecution

getTotalMemoryReservation

public io.airlift.units.DataSize getTotalMemoryReservation()

Specified by:

getTotalMemoryReservation in interface ManagedQueryExecution

public Optional<org.joda.time.DateTime> getExecutionStartTime()

Specified by:

getExecutionStartTime in interface QueryTracker.TrackedQuery

getLastHeartbeat

public org.joda.time.DateTime getLastHeartbeat()

Specified by:

getLastHeartbeat in interface QueryTracker.TrackedQuery

getEndTime

public Optional<org.joda.time.DateTime> getEndTime()

Specified by:

getBasicQueryInfo

public BasicQueryInfo getBasicQueryInfo()

Specified by:

getBasicQueryInfo in interface ManagedQueryExecution

start

public void start()

Specified by:

start in interface ManagedQueryExecution

addOutputInfoListener

public void addOutputInfoListener(Consumer<QueryExecution.QueryOutputInfo> listener)

Specified by:

addOutputInfoListener in interface QueryExecution

getStateChange

public com.google.common.util.concurrent.ListenableFuture<QueryState> getStateChange(QueryState currentState)

Specified by:

getStateChange in interface QueryExecution

addStateChangeListener

public void addStateChangeListener(StateMachine.StateChangeListener<QueryState> stateChangeListener)

Description copied from interface: ManagedQueryExecution

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.

Specified by:

addStateChangeListener in interface ManagedQueryExecution

addFinalQueryInfoListener

public void addFinalQueryInfoListener(StateMachine.StateChangeListener<QueryInfo> stateChangeListener)

Description copied from interface: QueryExecution

Add a listener for the final query 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.

Specified by:

addFinalQueryInfoListener in interface QueryExecution
