##Acquired Knowledge

• VirtualTopics will be save how persistent messages if delivery mode is PERSISTENT, and has a Consumer.A.VirtualTopic created

• Topics, will use percent stored used if delivery mode is PERSISTENT and exist a durable subscriber to a topic

• Queues, will use percent stored used if delivery mode is PERSISTENT

Queueu = Persistent = STORE percent used Queueu = Non Persisten = TEMP percent used

Topic = non durable subscriber = dont save message Topic = durable subscriber = Non Persistent = TEMP percent used Topic = durable subscriber = Persistent = STORE percent used

VirtualTopic = without a consumer = dont save message VirtualTopic = consumer already existent = Non Persistent = TEMP percent used VirtualTopic = consumer already existent = Persistent = STORE percent used

Create activemq container with disk space with a defined size, for help with tests.
