The example below is using the name <b>></b> to indicate 'match all topics'. You could use this wildcard to apply different virtual topic policies in different hierarchies.</p>

<p>Note that making a topic virtual does add a small CPU overhead when sending messages to the topic but it is fairly small. From version <b>5.4</b>, dispatch from virtual topics to subscription queues can be <b>selectorAware</b> such that only messages that match one of the existing subscribers are actually dispatched. Using this option prevents the build up of unmatched messages when selectors are used by exclusive consumers.</p>
