Topic views can replicate a topic branch to another branch that is throttled to update less often. We do this using a throttling clause.
map ?Demos/Sportsbook/Football/England// to Demos/Sportsbook/Free/Football/<path(5)> throttle to 1 update every 5 seconds.
Demos/Sportsbook/Freeto see the new topics.
Notice the new throttling clause:
throttle to 1 update every 5 seconds. As the topic name suggests, we have built a limited version of the application for non-paying customers, providing less frequent updates and so consuming less bandwidth.
Summary: Use the throttling clause to throttle the rate of reference topic updates.
