Method Detail

startWaitingForResources

void startWaitingForResources()

fail

void fail(Throwable cause)

addStateChangeListener

void addStateChangeListener(StateMachine.StateChangeListener<QueryState> stateChangeListener)

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.

getSession

Session getSession()

getUserMemoryReservation

io.airlift.units.DataSize getUserMemoryReservation()

getTotalMemoryReservation

io.airlift.units.DataSize getTotalMemoryReservation()

getTotalCpuTime

io.airlift.units.Duration getTotalCpuTime()

getBasicQueryInfo

BasicQueryInfo getBasicQueryInfo()

isDone

boolean isDone()

getErrorCode

Optional<ErrorCode> getErrorCode()

Returns:

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