             Summary: activemq artemis cluster mode can be one consumer ? 
                 Key: ARTEMIS-2510
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2510
             Project: ActiveMQ Artemis
          Issue Type: Wish
          Components: ActiveMQ-Artemis-Native
    Affects Versions: 2.10.1
         Environment: activemq artemis 2.10.1

package org.apache.activemq.artemis.jms.example;
import javax.jms.Connection;
/**
 * A simple example that demonstrates server side load-balancing of messages between the queue instances on different
 * nodes of the cluster.

public class ClusteredQueueExample {
   public static void main(final String[] args) throws Exception {
      Connection connection0 = null;

         // Step 2. Instantiate the Queue
         Queue queue = ActiveMQJMSClient.createQueue("exampleQueue");
         // Instantiate connection towards server 0
         ConnectionFactory cf0 = new ActiveMQConnectionFactory("tcp://localhost:61616");
         // Step 5. Look-up a JMS Connection Factory object from JNDI on server 1
         ConnectionFactory cf1 = new ActiveMQConnectionFactory("tcp://localhost:61617");
         // Step 6. We create a JMS Connection connection0 which is a connection to server 0
         connection0 = cf0.createConnection();
         // Step 7. We create a JMS Connection connection1 which is a connection to server 1
         connection1 = cf1.createConnection();
         // Step 8. We create a JMS Session on server 0
         Session session0 = connection0.createSession(false, Session.AUTO_ACKNOWLEDGE);
         // Step 9. We create a JMS Session on server 1
         Session session1 = connection1.createSession(false, Session.AUTO_ACKNOWLEDGE);
         // Step 10. We start the connections to ensure delivery occurs on them
         connection0.start();

         // Step 14. We now consume those messages on *both* server 0 and server 1.
         // We note the messages have been distributed between servers in a round robin fashion
         // JMS Queues implement point-to-point message where each message is only ever consumed by a
         // maximum of one consumer

Use the clustered-queue demo can be implement one producer send message to artemis queue,but It must be use all （in clusters） consumers to consume？
