    // Pass Mapped Diagnostic Context (MDC) into child thread, for logging Request ID
    final Map<String, String> contextMap = MDC.getCopyOfContextMap();
    Runnable task = () -> {
        if (contextMap != null) {

    Future<?> future = executorService.submit(task);
    task.run();

    // Wait for background task, log out metrics
    future.get();
