A signal is a notification that something has occurred in a CDF process. Users and systems may listen to signals by creating a sink and attaching subscriptions with a filter that matches the signals they are interested in. Subscriptions tie sinks to topics. Each topic represents some CDF resource like integrations or workflows. When a signal is emitted for a resource, all subscriptions for that resource's topic are evaluated. If the signal matches the subscription filter, it is pushed to the the sink.
