NATS JetStream also implements subject-based addressing at the stream level (unlike Kafka where 1 stream = 1 topic, and you can only use the message's key for distribution, not for addressing). So you can for example ask for [the first/the last/all] of the messages on a particular subject, or on a hierarchy of subjects by using wildcards. All the filtering is done at the server level. |
