Example 6 with VoidNamespaceSerializer

use of org.apache.flink.runtime.state.VoidNamespaceSerializer in project flink by apache.

the class BatchExecutionInternalTimeServiceTest method testSettingSameKeyDoesNotFireTimers.

@Test
public void testSettingSameKeyDoesNotFireTimers() {
    BatchExecutionKeyedStateBackend<Integer> keyedStatedBackend = new BatchExecutionKeyedStateBackend<>(KEY_SERIALIZER, new KeyGroupRange(0, 1));
    InternalTimeServiceManager<Integer> timeServiceManager = BatchExecutionInternalTimeServiceManager.create(keyedStatedBackend, this.getClass().getClassLoader(), new DummyKeyContext(), new TestProcessingTimeService(), Collections.emptyList());
    List<Long> timers = new ArrayList<>();
    InternalTimerService<VoidNamespace> timerService = timeServiceManager.getInternalTimerService("test", KEY_SERIALIZER, new VoidNamespaceSerializer(), LambdaTrigger.eventTimeTrigger(timer -> timers.add(timer.getTimestamp())));
    keyedStatedBackend.setCurrentKey(1);
    timerService.registerEventTimeTimer(VoidNamespace.INSTANCE, 123);
    keyedStatedBackend.setCurrentKey(1);
    assertThat(timers, equalTo(Collections.emptyList()));
}

Example 7 with VoidNamespaceSerializer

use of org.apache.flink.runtime.state.VoidNamespaceSerializer in project flink by apache.

the class BatchExecutionInternalTimeServiceTest method testFiringEventTimeTimers.

@Test
public void testFiringEventTimeTimers() throws Exception {
    BatchExecutionKeyedStateBackend<Integer> keyedStatedBackend = new BatchExecutionKeyedStateBackend<>(KEY_SERIALIZER, new KeyGroupRange(0, 1));
    InternalTimeServiceManager<Integer> timeServiceManager = BatchExecutionInternalTimeServiceManager.create(keyedStatedBackend, this.getClass().getClassLoader(), new DummyKeyContext(), new TestProcessingTimeService(), Collections.emptyList());

    keyedStatedBackend.setCurrentKey(1);
    timerService.registerEventTimeTimer(VoidNamespace.INSTANCE, 123);
    // advancing the watermark should not fire timers
    timeServiceManager.advanceWatermark(new Watermark(1000));
    timerService.deleteEventTimeTimer(VoidNamespace.INSTANCE, 123);
    timerService.registerEventTimeTimer(VoidNamespace.INSTANCE, 150);
    // changing the current key fires all timers
    keyedStatedBackend.setCurrentKey(2);
    assertThat(timers, equalTo(Collections.singletonList(150L)));
