NATS

NATS is a lightweight messaging system, and its JetStream layer adds persistent streams, durable consumers and acknowledgements. This tag collects guides about using NATS JetStream to keep RSS and Atom feeds fresh. Articles explain how to model a stream for publish events, send messages with identifiers that remove duplicates and read them with a durable pull consumer. They also cover batching, idempotent rebuilds, atomic file writes, redelivery limits and a timer as a safety net. The advice helps developers deliver new articles into a feed within seconds and share them on social networks automatically.
