NATS: The Challenger to Kafka's Messaging Throne
summary
NATS claims simple deployment and millions of messages per second throughput while keeping security and multi-tenancy; architecture splits into NATS Core (publish/subscribe with subject wildcards, queue groups for even load distribution) and JetStream (persistent streams, replay policies, retention by time/count/size). JetStream adds a key-value store and object store, supports decoupled flow control so slow consumers don’t block producers, and uses gossip for discovery plus RAFT for leader election; demo shows nats server run, pub/sub, queue groups and request/reply working.
