Examples with PER_PARTITION com.hazelcast.config.MaxSizePolicy.PER_PARTITION used on opensource projects

Example 1 with PER_PARTITION

use of com.hazelcast.config.MaxSizePolicy.PER_PARTITION in project hazelcast by hazelcast.

the class CustomEvictionPolicyComparatorTest method custom_eviction_policy_removes_correct_entries.

@Test
public void custom_eviction_policy_removes_correct_entries() {
    int sampleCount = SAMPLE_COUNT;
    Config config = getConfig();
    config.setProperty(PARTITION_COUNT.getName(), "1");
    config.getMapConfig(mapName).getEvictionConfig().setComparator(new OddEvictor()).setMaxSizePolicy(PER_PARTITION).setSize(sampleCount);
    HazelcastInstance instance = createHazelcastInstance(config);
    IMap<Integer, Integer> map = instance.getMap(mapName);
    final CountDownLatch eventLatch = new CountDownLatch(1);
    final Queue<Integer> evictedKeys = new ConcurrentLinkedQueue<>();
    map.addEntryListener((EntryEvictedListener<Integer, Integer>) event -> {
        evictedKeys.add(event.getKey());
        eventLatch.countDown();
    }, false);
    for (int i = 0; i < sampleCount + 1; i++) {
        map.put(i, i);
    }
    assertOpenEventually("No eviction occurred", eventLatch);
    for (Integer key : evictedKeys) {
        assertTrue(format("Evicted key should be an odd number, but found %d", key), key % 2 != 0);
    }
