When a datastream is deleted and its destination topic needs to be discarded, delay the deletion of the topic for an hour. This will allow all running instances to finish pumping messages to the topic. For now, this is all handled in memory, which means that if the leader coordinator is down before the KAC is deleted, the topic will remain alive. A possible integration with the Kafka GC or a simple ZK-backed GC for Brooklin is under consideration.
