Example 1 with BasicQueryStats

use of com.facebook.presto.server.BasicQueryStats in project presto by prestodb.

the class QueryStateMachine method getBasicQueryInfo.

public BasicQueryInfo getBasicQueryInfo(Optional<BasicStageExecutionStats> rootStage) {
    // Query state must be captured first in order to provide a
    // correct view of the query.  For example, building this
    // information, the query could finish, and the task states would
    // never be visible.
    QueryState state = queryState.get();
    BasicStageExecutionStats stageStats = rootStage.orElse(EMPTY_STAGE_STATS);
    BasicQueryStats queryStats = new BasicQueryStats(queryStateTimer.getCreateTime(), getEndTime().orElse(null), queryStateTimer.getWaitingForPrerequisitesTime(), queryStateTimer.getQueuedTime(), queryStateTimer.getElapsedTime(), queryStateTimer.getExecutionTime(), getCurrentRunningTaskCount(), getPeakRunningTaskCount(), stageStats.getTotalDrivers(), stageStats.getQueuedDrivers(), stageStats.getRunningDrivers(), stageStats.getCompletedDrivers(), stageStats.getRawInputDataSize(), stageStats.getRawInputPositions(), stageStats.getCumulativeUserMemory(), stageStats.getCumulativeTotalMemory(), stageStats.getUserMemoryReservation(), stageStats.getTotalMemoryReservation(), succinctBytes(getPeakUserMemoryInBytes()), succinctBytes(getPeakTotalMemoryInBytes()), succinctBytes(getPeakTaskTotalMemory()), succinctBytes(getPeakNodeTotalMemory()), stageStats.getTotalCpuTime(), stageStats.getTotalScheduledTime(), stageStats.isFullyBlocked(), stageStats.getBlockedReasons(), stageStats.getTotalAllocation(), stageStats.getProgressPercentage());
    return new BasicQueryInfo(queryId, session.toSessionRepresentation(), Optional.of(resourceGroup), state, memoryPool.get().getId(), stageStats.isScheduled(), self, query, queryStats, failureCause.get(), queryType, warningCollector.getWarnings(), preparedQuery);
}

Example 2 with BasicQueryStats

use of com.facebook.presto.server.BasicQueryStats in project presto by prestodb.

the class TestMemoryManager method isBlockedWaitingForMemory.

private static boolean isBlockedWaitingForMemory(BasicQueryInfo info) {
    BasicQueryStats stats = info.getQueryStats();
    boolean isWaitingForMemory = stats.getBlockedReasons().contains(WAITING_FOR_MEMORY);
    if (!isWaitingForMemory) {
        return false;
    }
    // queries are not marked as fully blocked if there are no running drivers
    return stats.isFullyBlocked() || stats.getRunningDrivers() == 0;
