Example 66 with Queue

use of org.apache.activemq.artemis.core.server.Queue in project activemq-artemis by apache.

the class SlowConsumerTest method testMultipleConsumersOneQueue.

/**
 * This test creates 3 consumers on one queue. A producer sends
 * messages at a rate of 2 messages per second. Each consumer
 * consumes messages at rate of 1 message per second. The slow
 * consumer threshold is 1 message per second.
 * Based on the above settings, slow consumer removal will not
 * be performed (2 < 3*1), so no consumer will be removed during the
 * test, and all messages will be received.
