Example 1 with CpuTimer

use of com.facebook.airlift.stats.CpuTimer in project presto by prestodb.

the class PrioritizedSplitRunner method process.

public ListenableFuture<?> process() {
    try {
        long startNanos = ticker.read();
        start.compareAndSet(0, startNanos);
        lastReady.compareAndSet(0, startNanos);

        waitNanos.getAndAdd(startNanos - lastReady.get());
        CpuTimer timer = new CpuTimer();
        ListenableFuture<?> blocked = split.processFor(SPLIT_RUN_QUANTA);
        CpuTimer.CpuDuration elapsed = timer.elapsedTime();
        long quantaScheduledNanos = ticker.read() - startNanos;
        scheduledNanos.addAndGet(quantaScheduledNanos);
        priority.set(taskHandle.addScheduledNanos(quantaScheduledNanos));
        lastRun.set(ticker.read());

            unblockedQuantaWallTime.add(elapsed.getWall());
        } else {
            blockedQuantaWallTime.add(elapsed.getWall());
        }
        long quantaCpuNanos = elapsed.getCpu().roundTo(NANOSECONDS);
        cpuTimeNanos.addAndGet(quantaCpuNanos);
        globalCpuTimeMicros.update(quantaCpuNanos / 1000);
