Examples with Event io.zeebe.client.event.Event used on opensource projects

Example 1 with Event

use of io.zeebe.client.event.Event in project zeebe by zeebe-io.

the class ClusteringRule method createTopic.

/**
 * Creates a topic with the given partition count in the cluster.
 *
 * This method returns to the user, if the topic and the partitions are created
 * and the replication factor was reached for each partition.
 * Besides that the topic request needs to be return the created topic.
 *
 * The replication factor is per default {@link #DEFAULT_REPLICATION_FACTOR}, but can be modified with
 * {@link #setReplicationFactor(int)}.
 *
 * @param topicName
 * @param partitionCount
 * @return
 */

    final Event topicEvent = zeebeClient.topics().create(topicName, partitionCount).execute();
    assertThat(topicEvent.getState()).isEqualTo("CREATED");
    waitForTopicPartitionReplicationFactor(topicName, partitionCount, replicationFactor);
    return waitForSpreading(() -> waitForTopicAvailability(topicName));
}

Example 2 with Event

use of io.zeebe.client.event.Event in project zeebe by zeebe-io.

the class CreateTopicTest method shouldCreateTopic.

@Test

    // given
    brokerRule.onExecuteCommandRequest(Protocol.SYSTEM_PARTITION, EventType.TOPIC_EVENT, "CREATE").respondWith().key(123).position(456).event().allOf((r) -> r.getCommand()).put("state", "CREATED").done().register();

}

Example 3 with Event

    // when
    final Future<Event> foo = topics.create("foo", 2).executeAsync();
