the class BaseDatarouterServletContextListener method processListeners.

private void processListeners(OnAction onAction, boolean executeAllListenersSynchronously) {
    ThreadFactory factory = new NamedThreadFactory("datarouterListenerExecutor", false);
    ExecutorService executor = Executors.newFixedThreadPool(allListeners.size(), factory);

    for (Pair<ExecutionMode, List<DatarouterAppListener>> listenersByShutdownMode : listenersByExecutionMods) {
        List<DatarouterAppListener> listeners = listenersByShutdownMode.getRight();
        ExecutionMode executionMode = executeAllListenersSynchronously ? ExecutionMode.SYNCHRONOUS : listenersByShutdownMode.getLeft();
        logger.warn("{} {}: [{}", onAction.display, executionMode.display, listeners.stream().map(listener -> listener.getClass().getSimpleName()).collect(Collectors.joining(", ")) + "]");
        if (executionMode == ExecutionMode.SYNCHRONOUS) {
            Scanner.of(listeners).map(executeOnAction(onAction)).forEach(timer::add);

            Scanner.of(listeners).parallel(new ParallelScannerContext(executor, listeners.size(), true)).map(executeOnAction(onAction)).forEach(timer::add);
            logger.info("Parallel {} total={}", onAction.display, System.currentTimeMillis() - shutdownParallelStartMillis);
        }
    }
    logger.warn(String.format("%s [total=%d][%s]", onAction, System.currentTimeMillis() - shutdownStartMillis, timer.getPhaseNamesAndTimes().stream().map(pair -> pair.getLeft() + "=" + pair.getRight()).collect(Collectors.joining("]["))));
    ExecutorServiceTool.shutdown(executor, Duration.ofSeconds(2));
}

Example 2 with NamedThreadFactory

use of io.datarouter.util.concurrent.NamedThreadFactory in project datarouter by hotpads.

the class BaseConveyors method start.

protected void start(Conveyor conveyor, int numThreads, long delaySeconds) {
    String name = conveyor.getName();
    Require.notContains(execsAndConveyorsByName.keySet(), name, name + " already exists");
    String threadGroupName = name;
    ThreadFactory threadFactory = new NamedThreadFactory(threadGroupName, true);
    ScheduledExecutorService exec = Executors.newScheduledThreadPool(numThreads, threadFactory);
    for (int i = 0; i < numThreads; ++i) {
        exec.scheduleWithFixedDelay(conveyor, delaySeconds, delaySeconds, TimeUnit.SECONDS);
    }
    instanceRegistry.register(exec);
