Example 1 with IQueue

use of com.hazelcast.core.IQueue in project orientdb by orientechnologies.

the class HazelcastQueueThroughputTest method main.

public static void main(String[] args) throws InterruptedException {
    final HazelcastInstance hz = Hazelcast.newHazelcastInstance();
    final IQueue[] ring = new IQueue[QUEUE_RING_SIZE];
    for (int q = 0; q < QUEUE_RING_SIZE; ++q) ring[q] = hz.getQueue("test" + q);
    final long start = System.currentTimeMillis();
    long lastLap = start;
    Thread t = new Thread() {

        long lastLap = start;

        @Override
        public void run() {
            int senderQueueIndex = 0;
            System.out.println((System.currentTimeMillis() - lastLap) + " Start receiving msgs");
            for (int i = 1; i < TOTAL + 1; ++i) {
                try {
                    if (senderQueueIndex >= QUEUE_RING_SIZE)
                        senderQueueIndex = 0;
                    Object msg = ring[senderQueueIndex++].take();
                    if (i % LAP == 0) {
                        final long lapTime = System.currentTimeMillis() - lastLap;
                        System.out.printf("<- messages %d/%d = %dms (%f msg/sec)\n", i, TOTAL, lapTime, ((float) LAP * 1000 / lapTime));

    int receiverQueueIndex = 0;
    System.out.println((System.currentTimeMillis() - lastLap) + " Start sending msgs");
    for (int i = 1; i < TOTAL + 1; ++i) {
        if (receiverQueueIndex >= QUEUE_RING_SIZE)
            receiverQueueIndex = 0;
        ring[receiverQueueIndex++].offer(i);
        if (i % LAP == 0) {
            final long lapTime = System.currentTimeMillis() - lastLap;
            System.out.printf("-> messages %d/%d = %dms (%f msg/sec)\n", i, TOTAL, lapTime, ((float) LAP * 1000 / lapTime));
            lastLap = System.currentTimeMillis();
        }
    }
    System.out.println((System.currentTimeMillis() - start) + " Finished sending msgs");
    t.join();
    System.out.println((System.currentTimeMillis() - start) + " Test finished");
}

Example 2 with IQueue
