 NATS is a publish subscribe messaging system. Subscribers listening on a subject receive messages on that subject. If the subscriber is not actively listening on the subject, the message is not received. Subscribers can use the wildcard tokens such as  `*` and `>` to match a single token or to match the tail of a subject.
