" summary

NATS is a compact, high‑performance messaging system with a ten‑command text protocol, default 1 MB default payload and a Go canonical client; it gives pub/sub, request‑reply and queue groups for load balancing, automatic reconnection (every ~2s) with an 80 MB client buffer and slow‑consumer disconnect after about two seconds. NATS supports TLS, a full‑mesh cluster (ports 4222/6222 plus monitoring), NATS Streaming (Stan) using protobuf with Raft or warm failover, official Docker images, Prometheus exporter and an operator; tests show ~21M msg/s single pub‑sub and ~80M aggregate, clusters up to 50–100 node clusters tested.
