Examples with Host io.confluent.ksql.execution.streams.RoutingFilter.Host used on opensource projects

Example 6 with Host

use of io.confluent.ksql.execution.streams.RoutingFilter.Host in project ksql by confluentinc.

the class MaximumLagFilterTest method filter_shouldNotIncludeAboveThreshold.

@Test
public void filter_shouldNotIncludeAboveThreshold() {
    // The max end offset is 15, so the lag for HOST is 12
    // Given:
    when(routingOptions.getMaxOffsetLagAllowed()).thenReturn(11L);
    // When:
    filter = MaximumLagFilter.create(Optional.of(lagReportingAgent), routingOptions, HOSTS, APPLICATION_ID, STATE_STORE, PARTITION).get();
    // Then:
    final Host host = filter.filter(HOST1);
    assertFalse(host.isSelected());
    assertEquals(host.getReasonNotSelected(), "Host excluded because lag 12 exceeds maximum allowed lag 11.");
}

Example 7 with Host

use of io.confluent.ksql.execution.streams.RoutingFilter.Host in project ksql by confluentinc.

the class LivenessFilterTest method shouldFilterActiveAlive.

@Test
public void shouldFilterActiveAlive() {
    // Given:
    allHostsStatus = ImmutableMap.of(activeHost, HOST_ALIVE, standByHost1, HOST_DEAD, standByHost2, HOST_DEAD);
    when(heartbeatAgent.getHostsStatus()).thenReturn(allHostsStatus);
    // When:
    final Host filterActive = livenessFilter.filter(activeHost);
    final Host filterStandby1 = livenessFilter.filter(standByHost1);
    final Host filterStandby2 = livenessFilter.filter(standByHost2);
    // Then:
    assertThat(filterActive.isSelected(), is(true));
    assertThat(filterStandby1.isSelected(), is(false));
    assertThat(filterStandby1.getReasonNotSelected(), is("Host is not alive as of time 0"));
    assertThat(filterStandby2.isSelected(), is(false));
    assertThat(filterStandby2.getReasonNotSelected(), is("Host is not alive as of time 0"));
}

Example 8 with Host

    // When:
    final Host filterActive = livenessFilter.filter(activeHost);
    final Host filterStandby1 = livenessFilter.filter(standByHost1);

}

Example 9 with Host

use of io.confluent.ksql.execution.streams.RoutingFilter.Host in project ksql by confluentinc.

the class ActiveHostFilterTest method shouldFilterActive.

@Test
public void shouldFilterActive() {
    // Given:
    // When:
    final Host filterActive = activeHostFilter.filter(activeHost);
    final Host filterStandby = activeHostFilter.filter(standByHost);
    // Then:

    assertThat(filterStandby.isSelected(), is(false));
    assertThat(filterStandby.getReasonNotSelected(), is("Host is not the active host for this partition."));
}

Example 10 with Host
